The role of UV absorber UV-1 in electric vehicle charging facilities

1. Introduction: Why is the ultraviolet absorber UV-1 so important?

In this era of rapid technological change, electric vehicles (EVs) have become the pioneer of the global green energy revolution. From Tesla to BYD, from NIO to Xiaopeng, major brands are rushing to launch electric cars with excellent performance, bringing earth-shaking changes to human travel methods. However, just as a precision machine requires countless parts to work together, the success of an electric vehicle cannot be separated from a key link – charging facilities. These seemingly inconspicuous charging piles not only carry the heavy responsibility of “recharge” the vehicles, but also are an important part of the entire new energy ecosystem.

However, have you ever thought that these charging facilities exposed to outdoor environments have to withstand the test of wind, rain and scorching sun every day? Especially in areas with strong sunlight, the damage caused by ultraviolet rays to the plastic shells, cable insulation layers, and display screens of charging equipment cannot be ignored. If exposed to ultraviolet light for a long time, these materials may age, discolor or even crack, which seriously affects the service life and appearance quality of the equipment. At this time, the ultraviolet absorber UV-1 became the “behind the scenes” to save these charging facilities.

So, what exactly is UV absorber UV-1? What role does it play in an electric vehicle charging facility? This article will take you into the deep understanding of this mysterious chemical and explore how it provides comprehensive protection for charging facilities through its own characteristics. We will analyze it from multiple angles such as its basic principles, product parameters, practical application cases, etc., and at the same time, combined with the research results of relevant domestic and foreign literature, we will present you a complete picture of the ultraviolet absorber UV-1.

Whether you are an ordinary reader interested in new energy technology or a professional in related industries, this article will provide you with rich knowledge and practical insights. Let’s unveil the veil of UV absorber UV-1 and explore how it can safeguard electric vehicle charging facilities!

2. Basic principles and characteristics of UV absorber UV-1

(I) The hazards of ultraviolet rays and their protection needs

In nature, ultraviolet rays (UV) are electromagnetic radiation with short wavelengths, mainly divided into UVA (320-400nm), UVB (280-320nm) and UVC (100-280nm). Although UVC is usually absorbed by the ozone layer in the atmosphere and will not reach the ground, UVA and UVB can easily penetrate the atmosphere and have a profound impact on objects on Earth. For electric vehicle charging facilities, the harms brought by these ultraviolet rays mainly include the following points:

  1. Material Aging: UV rays can destroy chemical bonds in polymer materials.This leads to the gradual loss of flexibility of plastic shells, cable insulation layers and other polymer materials, and eventually problems such as embrittlement and cracking occur.
  2. Color fade: UV irradiation will decompose dyes or pigments, making the color on the surface of the equipment dull, seriously affecting the appearance quality.
  3. Function degradation: Some electronic components and display screens may have deteriorated performance or even fail completely due to the influence of ultraviolet rays.

To address these problems, scientists have developed a series of ultraviolet protection technologies, among which the ultraviolet absorber UV-1 stands out for its high efficiency and economics, becoming the preferred solution in the industry.

(II) Working mechanism of UV absorber UV-1

UV absorber UV-1 is an organic compound whose main components are usually benzotriazoles or hydroxybenzophenones. Its core function is to absorb the energy of ultraviolet rays and convert them into heat energy to release them, thereby preventing the ultraviolet rays from directly acting on the surface of the material. Specifically, the working mechanism of UV-1 can be divided into the following steps:

  1. Absorbing UV light: Specific functional groups in UV-1 molecules are able to selectively absorb ultraviolet energy in the wavelength range.
  2. Energy Conversion: The absorbed ultraviolet energy will be quickly converted into harmless heat energy and emitted into the environment.
  3. Stable material structure: By preventing the damage of ultraviolet rays to the polymer chain, UV-1 effectively delays the aging process of the material.

This “interception-conversion-protection” mechanism allows UV-1 to provide it with a lasting protective effect without affecting the original performance of the material.

(III) Main characteristics of UV absorber UV-1

Features Description
Efficient absorption Can absorb more than 95% of ultraviolet energy, covering the UVA and UVB bands
Chemical Stability Stabilize under high temperature and light conditions, and is not easy to decompose or evaporate
Good compatibility It can be well compatible with a variety of polymer materials and is suitable for different types of plastics and rubbers
Do not affect transparency When adding it, it will not significantly reduce the materialThe light transmittance of the material is particularly suitable for transparent parts
Low toxicity and environmental protection Complied with international environmental standards and is harmless to the human body and the environment

These characteristics make UV-1 an ideal ultraviolet protection additive, widely used in the automotive industry, construction fields, and electronic products industries.

(IV) Current status of domestic and foreign research

In recent years, with the rapid development of the electric vehicle industry, domestic and foreign scholars have also been studying the ultraviolet absorber UV-1 in depth. For example, a study by the University of Michigan in the United States showed that after 1,000 hours of ultraviolet radiation, the tensile strength of polycarbonate materials with appropriate amounts of UV-1 decreased by only 5%, much lower than that of the control group without UV-1 (about 30%). In China, the research team at Tsinghua University found that when UV-1 is combined with antioxidants, it can further improve the weather resistance of the material and extend its service life.

In addition, an experiment by BASF in Germany showed that UV-1 can not only protect the material itself, but also indirectly improve the appearance quality of the product. By simulating tests in real-life use environments, the researchers found that the shell of the charging facility with UV-1 added always maintained a bright color for two years, while samples without UV-1 added showed obvious fading.

To sum up, UV absorber UV-1 plays an important role in the protection of electric vehicle charging facilities due to its unique chemical structure and excellent performance. Next, we will further explore the specific performance of UV-1 in practical applications.

3. Application of UV absorber UV-1 in electric vehicle charging facilities

(I) Overview of application scenarios

Electric vehicle charging facilities usually include charging piles, charging guns, cables, and supporting control panels. Most of these devices are installed in outdoor environments and are exposed to challenges under natural conditions for a long time, such as extreme temperature changes, humidity fluctuations, and important UV radiation. UV absorber UV-1 is the key to playing its unique role in this complex environment.

The following are some typical application scenarios of UV-1 in electric vehicle charging facilities:

  1. Charging pile shell: The shell of the charging pile is mostly made of engineering plastics such as ABS, PC or PMMA, and these materials are prone to degradation under the action of ultraviolet rays. By adding UV-1 during the production process, the anti-aging ability of the shell can be significantly improved, making it more durable.
  2. Cable Sheath: The outer sheath of the charging cable is usually composed of PVC or TPE material,Some materials may harden or even crack under long-term exposure to ultraviolet rays, causing safety hazards. The addition of UV-1 helps maintain the flexibility and integrity of the sheath.
  3. Display and Touch Screen: Modern charging piles are generally equipped with LED displays or touch panels, and these optical components are very sensitive to ultraviolet rays. UV-1 can protect the screen from UV damage through coating or doping, ensuring its clarity and sensitivity.

(II) Product parameters and technical indicators

parameter name Specific value or range Remarks
Chemical Components Benzotriazoles or hydroxybenzophenone compounds There may be slightly different depending on the specific model
Absorption wavelength range 280-400nm Cover the UVA and UVB bands

Thermal Stability >250°C Ensure that there is no decomposition during processing
Solution Slightly soluble in water, easily soluble in organic solvents Easy to mix with other materials
Antioxidation properties Advance by 50%-70% It is better to use with antioxidants

(III) Actual case analysis

Case 1: Weather resistance test of a well-known brand charging pile

A well-known charging pile manufacturer introduced UV-1 in its new product and conducted a one-year outdoor weather resistance test. The results showed that after more than 2,000 hours of ultraviolet irradiation, the shell surface remained smooth and smooth, and the color was as bright as before; while the control group without UV-1 was significantly pulverized and faded. In addition, the test also found that the addition of UV-1 did not have any negative impact on the mechanical properties of the material (such as hardness, impact strength).

Case 2: Aging test of charging cable

A company focusing on electric vehicle charging equipmentWhen developing a new charging cable, try to incorporate the UV-1 into the sheathing material. After accelerated aging testing (simulating five years of outdoor use), the cable’s sheath remains well elastic and has no cracks or damage. In contrast, traditional cables no longer work properly under the same conditions. This result fully demonstrates the significant advantages of UV-1 in improving cable durability.

(IV) Economic and social benefits

Although the initial cost of UV absorber UV-1 is slightly higher than that of ordinary additives, its use can significantly reduce maintenance costs and replacement frequency in the long run, bringing considerable economic benefits to the enterprise. At the same time, since UV-1 can extend the service life of charging facilities and reduce resource waste, it also has important environmental significance and social value.

IV. Future development and challenges of UV-1 UV absorber

As the global focus on sustainable development and environmental protection continues to increase, the technology of the UV absorber UV-1 is also improving. The future development direction mainly includes the following aspects:

  1. Improve efficiency: By optimizing molecular structure, the ultraviolet absorption capacity and stability of UV-1 are further enhanced.
  2. Wind-out the scope of application: In addition to electric vehicle charging facilities, UV-1 is expected to find more use in the fields of photovoltaic panels, wind turbines, etc.
  3. Green and Environmentally friendly: Develop biodegradable or recyclable UV-1 alternatives to meet increasingly stringent environmental protection requirements.

Of course, UV-1 applications also face some challenges, such as how to balance costs and performance, how to ensure its reliability under extreme conditions, etc. But I believe that with the continuous advancement of science and technology, these problems will eventually be solved.

5. Conclusion: Little UV-1, the big guardian

Reviewing the full text, we can see that although the ultraviolet absorber UV-1 is inconspicuous, it is an indispensable part of the charging facilities of electric vehicles. It is like a silently dedicated guard, protecting the safety and beauty of these high-tech equipment in its own way. Whether it is resisting ultraviolet erosion or improving the weather resistance of the material, UV-1 has shown outstanding capabilities.

As an old saying goes, “Details determine success or failure.” In the tide of the new energy era, it is precisely because of the heroes behind the scenes like the UV-1 that we can enjoy a more convenient and reliable electric vehicle life. Let us pay our highest respect to this “invisible hero”!

Analysis of the advantages of UV absorber UV-1 in outdoor billboard production

3月 17th, 2025 News

UV absorber UV-1: “Invisible Guardian” of outdoor billboards

In modern society, outdoor billboards are like “information beacons” in the city, attracting people’s attention with colorful pictures and eye-catching designs. However, behind these dazzling visual feasts, there is a problem that cannot be ignored – ultraviolet erosion. Just as fruits exposed to sunlight gradually lose moisture and luster, outdoor billboards also face the risk of fading, aging and even damage when exposed to ultraviolet light for a long time. UV absorber UV-1 is the “behind the scenes” that solves this problem.

UV absorber UV-1 is an efficient functional chemical that can effectively absorb and convert ultraviolet energy in sunlight, thereby protecting the material from damage from ultraviolet rays. It is like an invisible protective cover that converts the energy of ultraviolet rays into heat or harmless low-energy radiation to release it, avoiding the direct damage to the surface coating of the billboard by ultraviolet rays. This magical function makes UV-1 an indispensable and important ingredient in outdoor billboard production.

This article will explore in-depth the advantages of UV absorber UV-1 in outdoor billboard production from multiple angles. First, we will introduce the basic principles of UV-1 and its application effects in different materials; secondly, through analyzing relevant domestic and foreign literature, we will reveal the significant role of UV-1 in improving the durability and aesthetics of billboards; then, based on actual cases, we will show how UV-1 can help billboard manufacturers reduce costs, improve product quality, and bring consumers a better visual experience. Let us uncover the mystery of this “Invisible Guardian” and explore its unique value in the modern advertising industry.

Basic characteristics and working principle of UV-1 UV absorber

UV absorber UV-1 is a highly efficient ultraviolet protective agent. Its core function is to absorb and convert ultraviolet energy, thereby protecting the material from ultraviolet rays. Specifically, the working mechanism of UV-1 can be divided into three key steps: absorption, conversion and release. When UV light hits the surface of a material containing UV-1, UV-1 molecules quickly capture high-energy photons in the UV light and convert their energy into heat or other low-energy forms of radiation, which are safely released into the environment. This process not only avoids direct damage to the material by ultraviolet rays, but also ensures long-term stability of material performance.

From the chemical structure, the ultraviolet absorber UV-1 is a hydroxybenzone compound, with good light stability, heat resistance and chemical compatibility. Its molecular structure contains specific aromatic rings and carbonyl functional groups, which impart excellent UV absorption capacity to UV-1. Research shows that UV-1 has particularly strong absorption capacity for ultraviolet rays (i.e., UVA and partial UVB) with wavelengths ranging from 290nm to 400nm, which is the key band that causes the aging of outdoor materials. Therefore, UV-1Able to function within an effective range and provide comprehensive UV protection.

In addition, UV-1 also has excellent dispersive and mobility control capabilities. This means that it can be evenly distributed in substrates such as coatings and plastics, while maintaining high stability and will not fail or migrate due to changes in the external environment. This feature makes it ideal for outdoor billboards, which require long-term exposure to complex environments. For example, under high temperature, high humidity or strong light conditions, UV-1 can continue to play its protective role and extend the service life of billboards.

In order to better understand the technical parameters of UV-1, we can summarize its main characteristics through the following table:

Parameter name Numerical Range Instructions
Absorption wavelength range 290nm – 400nm For UVA and partial UVB bands, the main UV bands covering material aging.
Large absorption wavelength About 350nm UV-1 has a high absorption efficiency at this wavelength, which can greatly reduce the impact of ultraviolet rays on the material.
Heat resistance temperature ?200°C Stabilizes stability during high-temperature processing and is suitable for a variety of industrial application conditions.
Dispersion Even distribution It is easy to disperse in the substrate to ensure the consistency of ultraviolet protection effect.
Photostability >1000 hours After long-term lighting, it can still maintain efficient absorption capacity, and is suitable for long-term outdoor use scenarios.
Compatibility Widely compatible Can be used in combination with a variety of resins, solvents and other additives without affecting the overall formulation performance.

Through an in-depth understanding of the basic characteristics of UV-1, we can see its huge potential in outdoor billboard making. Whether from a technical perspective or a practical application perspective, UV-1 is a rare high-performance ultraviolet protective agent, providing all-round protection for billboards.

UV absorber UV-1Analysis of application scenarios in outdoor billboards

In the field of outdoor billboards, the application scenarios of UV absorber UV-1 are very wide, covering almost all mainstream material types. Below we will focus on analyzing the specific application and effectiveness of UV-1 in three common billboard materials.

1. Paint-type billboard

Paint-type billboards are one of the common forms of outdoor advertising. The surface is usually composed of paint or spray paint, with bright colors and clear patterns. However, traditional paints are prone to powdering, cracking and fading under ultraviolet rays, which seriously affects the advertising effect. These problems have been significantly improved after the introduction of UV-1.

The application of UV-1 in coatings is mainly reflected in the following aspects:

  • Enhanced Weather Resistance: By absorbing ultraviolet rays, UV-1 effectively delays the aging process of pigments and resins in the paint, allowing billboards to maintain their original color when exposed to sunlight for a long time.
  • Reduce surface damage: The addition of UV-1 reduces the destruction effect of UV rays on the coating molecular chains and reduces the probability of surface cracking and powdering.
  • Optimize construction performance: UV-1 has good compatibility with the coating system, and will not affect the leveling and adhesion of the coating, making it convenient for large-scale industrial production.

The following is a comparison of typical parameters of UV-1 in paint-type billboards:

Project Ordinary Paint Add UV-1 paint Elevation
Color fastness (rating) Level 3 Level 5 Advance by 67%
Surface crack resistance time (years) 2 years Above 5 years Extend more than 150%
Service life (years) 3-5 years 8-10 years Extend about 160%

2. PVC billboard

PVC (polyvinyl chloride) billboards are lightweight, easy to process andThe advantage of low cost is widely used in various outdoor publicity scenarios. However, PVC materials themselves are extremely sensitive to ultraviolet rays, and long-term exposure to the sun will cause them to become brittle, yellow or even crack. The introduction of UV-1 has brought revolutionary improvements to PVC billboards.

The main roles of UV-1 in PVC billboards include:

  • Inhibit photodegradation: UV-1 can prevent free radical reactions caused by ultraviolet rays, slow down the speed of PVC molecular chain breakage, thereby extending the service life of the material.
  • Prevent color changes: UV-1 can effectively absorb short-wave radiation from ultraviolet rays and prevent PVC surface from yellowing or discoloring due to light oxidation.
  • Improving Mechanical Performance: By protecting the internal structural integrity of PVC, UV-1 helps maintain the flexibility and strength of billboards.

The following are the specific data on improving the performance of UV-1 on PVC billboards:

Project UV-1 not added Add UV-1 Elevation
UV resistance (h) About 500 hours >2000 hours Advance by more than 300%
Yellow Index Sharp increase Almost unchanged Important improvement
Tension Strength (MPa) 20 30 Advance by 50%

3. Digital printing billboard

With the development of digital printing technology, digital printing billboards have gradually become the mainstream of the market. This billboard adopts inkjet printing technology, which has the advantages of high resolution and delicate images, but also faces the challenges of ink durability and coating protection. The addition of UV-1 provides a comprehensive UV protection solution for digital printed billboards.

The application characteristics of UV-1 in digital printing billboards are as follows:

  • Protective ink layer: UV-1 can effectively absorb ultraviolet rays.Prevent dye decomposition in the ink, thus ensuring that the ad screen remains bright at all times.
  • Enhanced Coating Performance: UV-1 works synergistically with the coating material to improve the wear and scratch resistance of the coating, and further improve the overall quality of the billboard.
  • Simplify production process: Since UV-1 is easy to disperse and has strong stability, its addition will not cause additional burden on the existing production process, but will help improve production efficiency.

The following is a comparison of the performance of UV-1 in digital printing billboards:

Project General coating Add UV-1 coating Elevation
Image fidelity General High Sharp improvement
Coating Durability (month) 6 months >18 months Extend by more than 200%
Cost-effective Higher Better Comprehensive cost reduction

To sum up, the use of UV absorber UV-1 in different types of billboards has shown excellent results. Whether it is paint, PVC or digital printed billboards, UV-1 can provide it with strong UV protection, significantly extending its service life and improving visual effects. These advantages not only meet market demand, but also inject new vitality into the advertising industry.

The current situation and future development trends of domestic and foreign research

Around the world, the research and application of UV-1, the ultraviolet absorber has become an important branch in the field of materials science. In recent years, domestic and foreign scholars have conducted a lot of research on UV-1 performance optimization, development of new composite materials, and sustainable development. These research results not only enrich the basic theory of UV-1, but also promote its widespread application in outdoor billboards and other fields.

1. Progress in foreign research

European and American countries started research in the field of ultraviolet absorbers early and accumulated rich experience and technical achievements. A study from the University of Michigan shows that by adjusting UV-1 pointsThe number of hydroxyl groups in the substructure can significantly improve its absorption efficiency to the UVA band while reducing interference to visible light. This discovery offers new possibilities for the use of UV-1 in high-end billboard coatings. In addition, the Fraunhofer Institute in Germany has developed a UV-1 dispersion method based on nanotechnology, which can evenly distribute UV-1 particles in the substrate, further enhancing its protective effect.

It is worth mentioning that a research team from Tokyo University of Technology in Japan proposed the concept of a “smart” ultraviolet absorber. They introduced temperature-sensitive groups into UV-1 molecules, so that they had the ability to adjust their absorption efficiency as temperature changes. This innovative design not only improves the adaptability of UV-1 in extreme climates, but also opens up new paths for the long-lasting use of outdoor billboards in high or low temperature environments.

2. Domestic research trends

Although my country’s research in the field of ultraviolet absorbers started a little later, it has made significant progress in recent years. The research team from the Department of Chemical Engineering of Tsinghua University successfully synthesized a new type of modified UV-1 material, whose large absorption wavelength expanded from the original 350nm to 380nm, with a wider coverage and stronger protection ability. This breakthrough result has been applied for a number of patents and has been practically applied in many well-known companies.

At the same time, the Department of Materials Sciences of Fudan University focuses on the study of the synergistic effects of UV-1 and other functional additives. They found that using UV-1 with antioxidants, light stabilizers and other substances can build a more complete protection system and significantly extend the service life of outdoor billboards. In addition, an experiment from the School of Environment of Zhejiang University showed that the application of UV-1 in biodegradable plastics has good environmental protection potential, which provides new ideas for the future development of green billboards.

3. Future development trends

As the global awareness of environmental protection increases, the research and development direction of the ultraviolet absorber UV-1 has gradually tilted towards greening and intelligentization. The following points may become the main trends in future development:

  1. Green and environmentally friendly UV-1: Many UV absorbers currently have certain ecological risks, such as difficulty in degradation or toxic to aquatic organisms. Therefore, the development of new biodegradable, non-toxic and harmless UV-1 materials will become a research hotspot.

  2. Multifunctional integrated design: The future UV-1 is expected to integrate more functions, such as antibacterial, anti-mold, self-cleaning, etc., to meet the diverse needs in different scenarios. This multifunctional integrated design will further broaden its application scope.

  3. Intelligent response system: With the help of advanced sensing technology and artificial intelligence algorithms, the future UV-1 may be realized to the external environment (such as purple).Real-time monitoring and dynamic adjustment of external strength, humidity, temperature, etc.) to achieve optimal protective effect.

  4. Low-cost large-scale production: Although UV-1 has excellent performance, its high cost is still a major bottleneck that restricts its widespread application. Therefore, finding cheap raw materials, optimizing production processes, and reducing manufacturing costs will be one of the key directions of future research.

To sum up, research on the ultraviolet absorber UV-1 at home and abroad is constantly deepening, and new technologies and new products are emerging one after another. These research results not only enhance the practical application value of UV-1, but also lay a solid foundation for the sustainable development of the outdoor billboard industry. It can be foreseen that in the near future, UV-1 will surely show greater potential and influence in more fields.

Comprehensive considerations on the economics and environmental protection of UV-1 in outdoor billboards

When exploring the application of UV absorber UV-1 in outdoor billboards, in addition to paying attention to its technical performance and protective effect, it also needs to conduct a comprehensive evaluation from the two dimensions of economic and environmental protection. These two factors are not only an important basis for corporate decision-making, but also a key criterion for measuring whether UV-1 truly meets market demand.

1. Economic analysis

In the short term, the introduction of UV-1 does increase the initial production cost of billboards. According to industry data, the cost of adding UV-1 to each ton of paint is about 500-1,000 yuan, accounting for about 5%-10% of the total cost. However, from the perspective of long-term economic benefits, the benefits brought by UV-1 far exceed its investment costs.

First, UV-1 significantly extends the service life of the billboard. Taking an ordinary paint-type billboard as an example, if UV-1 is not added, its average service life is only 3-5 years; and after UV-1 is added, its service life can be extended to 8-10 years, or even longer. This means that billboard replacement frequency is significantly reduced, thus reducing the cost of maintenance and remake. According to the current market conditions, the cost of replacing a billboard is about 80% of the initial production cost, so this item alone can save enterprises up to millions or even tens of millions of yuan in funds.

Secondly, UV-1 can also enhance the visual effect and brand value of billboards. UV-1 protected billboards can still maintain bright colors and clear patterns after long-term use, which not only enhances consumers’ visual experience, but also enhances the dissemination of brand image. Especially in the high-end advertising market, this high-quality performance can often obtain higher premium space, further increasing the profit returns of the company.

The following is a comparison of the specific economic data of UV-1:

Project UV-1 not added Add UV-1 Difference
Initial cost (yuan/square meter) 50 55 +10%
Service life (years) 3-5 years 8-10 years Extend more than 160%
Maintenance cost (yuan/time) 40 Reduced to near zero Remarkable decline
Total cost saving ratio – Save about 30%-50% in the long term Sharp improvement

2. Environmental protection analysis

As the global focus on environmental protection is increasing, the environmental advantages of UV-1 in outdoor billboards are also receiving more and more attention. Compared with traditional protective measures such as frequent replacement or coating of additional protective coatings, UV-1 is more efficient and low-carbon.

On the one hand, UV-1 indirectly reduces the consumption of raw materials and waste by extending the service life of billboards. According to statistics, the total amount of plastics, paints and other materials discarded due to the aging of billboards worldwide every year is as high as millions of tons. If UV-1 is widely adopted, this number will be reduced by at least 30%-50%, which is of great significance to alleviating resource pressure and environmental pollution.

On the other hand, the environmental protection properties of UV-1 itself are also constantly improving. In recent years, researchers have worked to develop new biodegradable UV-1 materials that can decompose naturally after completing protection tasks without causing long-term harm to the ecosystem. For example, certain UV-1 alternatives based on plant extracts have entered the experimental stage and are expected to be gradually put into commercial applications in the next few years.

In addition, UV-1 can also be combined with other environmentally friendly technologies to form a more complete solution. For example, using UV-1 with photocatalytic materials can not only absorb ultraviolet rays, but also decompose pollutants in the air, thus achieving dual environmental protection effects. This innovative design concept provides new possibilities for the outdoor billboard industry to transform to green.

The following is a summary of the specific advantages of UV-1 in terms of environmental protection:

Project UV-1 not added Add UV-1 Difference
Waste reduction ratio – ?30%-50% Sharp improvement
Reduced energy consumption ratio – ?20% Sharp improvement
Potential hazards to the environment Higher Reduced significantly Improving

3. Comprehensive evaluation

To sum up, the application of UV absorber UV-1 in outdoor billboards not only has excellent technical performance, but also shows significant advantages in economics and environmental protection. Although there may be certain cost investment in the short term, in the long run, the economic benefits and environmental value brought by UV-1 are enough to make up for this. Therefore, UV-1 is undoubtedly one of the solutions worth promoting in the current and future outdoor billboard production.

Conclusion: The future path of UV absorber UV-1

As society continues to increase its demand for high-quality outdoor advertising, the importance of the ultraviolet absorber UV-1 is becoming increasingly prominent. It is not just a simple chemical, but also a “secret weapon” for outdoor billboards to maintain a bright appearance for a long time. Through detailed discussion in this article, we learned that UV-1 can not only provide excellent UV protection in coatings, PVC and digital printed billboards, but also significantly extend the service life of billboards, thereby saving enterprises a lot of maintenance and replacement costs. In addition, UV-1’s contribution in environmental protection should not be underestimated. Its use greatly reduces material waste and environmental pollution, and has made positive contributions to sustainable development.

Looking forward, the development prospects of the ultraviolet absorber UV-1 are exciting. With the continuous advancement of technology, we have reason to believe that UV-1 will make greater breakthroughs in performance, cost and environmental protection. For example, the new generation of UV-1 may be more efficient and environmentally friendly, and can even achieve intelligent response and automatically adjust the protection effect according to different environmental conditions. This will not only improve the quality of outdoor billboards, but will also promote technological innovation in the entire advertising industry.

For outdoor billboard manufacturers, timely adopting and promoting UV-1 technology can not only enhance the competitiveness of the product, but also meet the increasingly strict conditions.environmental regulations. For consumers, this means they will enjoy a more lasting and more beautiful advertising experience. Therefore, UV absorber UV-1 is an ideal choice for outdoor billboard production, both from the perspective of economic benefits and social responsibility.

In short, UV-1 is not only a perfect combination of technology and art, but also a bridge connecting the present and the future. Let us look forward to the fact that with the help of UV-1, outdoor billboards will decorate our city with a more gorgeous posture and add more color and vitality to life.

The excellent protection effect of UV absorber UV-327 in high-end plastic products

3月 17th, 2025 News

UV absorber UV-327: Invisible guardian of high-end plastic products

In modern society, plastic products have become an indispensable part of our daily lives. From mobile phone cases to car dashboards, from food packaging to medical devices, plastics occupy an important position in various fields for their lightness, durability and economical characteristics. However, while enjoying these conveniences, we also face a problem that cannot be ignored – the erosion effect of ultraviolet rays on plastics. The ultraviolet rays in the sun are like an invisible knife, quietly weakening the strength of the plastic, changing its color, and even making it fragile and brittle. This phenomenon not only affects the appearance and service life of the product, but may also bring safety hazards.

It is in this context that the ultraviolet absorber UV-327 came into being. It is a high-performance ultraviolet protection additive, specially used to improve the durability and stability of plastic products in ultraviolet environments.

Basic Characteristics and Principles of UV-327

Chemical structure and physical properties

UV absorber UV-327 (chemical name: 2-(2′-hydroxy-5′-methylphenyl)benzotriazole) is a light stabilizer widely used in plastics and other polymer materials. Its chemical structure contains benzotriazole rings, a feature that imparts strong UV absorption capacity to UV-327. Specifically, the molecular formula of UV-327 is C15H11NO2 and the molecular weight is 241.26 g/mol. Its appearance is usually white to light yellow powder with melting points ranging from 108°C to 112°C, with good thermal and chemical stability. In addition, the density of UV-327 is about 1.3 g/cm³, and has low solubility. It is mainly suitable for organic solvent systems, such as alcohols and ester solvents.

Method of action

The core function of UV-327 is to absorb UV and convert it into harmless energy forms, thereby avoiding the damage to the plastic molecular chains by UV. This process can be divided into the following key steps:

  1. Ultraviolet capture
    When ultraviolet rays irradiate on the plastic surface containing UV-327, the benzotriazole ring in the UV-327 molecule preferentially absorbs ultraviolet rays with wavelengths ranging from 290nm to 400nm. This wavelength range is the part that has a great impact on plastic aging. By absorbing ultraviolet rays, UV-327 effectively blocks the possibility that ultraviolet rays can penetrate directly into the plastic interior.

  2. Energy Conversion
    After absorbing ultraviolet rays, UV-327 molecules enter an excited state. It then releases the absorbed energy in the form of thermal energy through non-radiative transitions, or consumes excess energy through intramolecular vibrations. This process not only avoids the direct damage to the plastic molecular chain by ultraviolet rays, but also ensures the stability of UV-327 itself and will not decompose or fail due to excessive absorption.

  3. Prevent free radical formation
    Ultraviolet-induced photooxidation reactions usually cause the plastic molecular chain to break and form free radicals. These free radicals further participate in the chain reaction, accelerating the aging process of plastics. UV-327 absorbs ultraviolet rays, reducing the chance of photooxidation reactions, thereby indirectly inhibiting the generation of free radicals and delaying the aging process of plastics.

Feature Advantages

The reason why UV-327 can become the first choice for high-end plastic products is closely related to its unique characteristics:

Features Description
Efficient absorption Can absorb ultraviolet rays with a wide wavelength range and cover key areas from 290nm to 400nm.

To sum up, UV-327 has become an indispensable light stabilizer in the plastics industry with its superior chemical structure and mechanism of action. Next, we will further explore the performance of UV-327 in different application scenarios and its significant advantages.
