UV absorber UV-326 is a highly effective chemical substance designed to prevent plastics and other organic materials from aging or discoloring due to long-term exposure to UV light. This compound is a benzotriazole ultraviolet absorber and is known for its excellent light stability and heat resistance. It can effectively absorb ultraviolet rays with wavelengths ranging from 280 to 340 nanometers, thus avoiding the damage to the molecular structure of the material by these high-energy rays.

The main function of UV-326 is to absorb UV light through the charge transfer mechanism within the molecule, converting it into harmless thermal energy and releasing it, rather than allowing these energy to trigger chemical reactions inside the material. This makes UV-326 an ideal choice for many industries, especially plastic products that require long outdoor use.

UV-326 plays a crucial role in the application of high-end electronic housings. Since the shells of this type of product are usually made of engineering plastics such as ABS and PC, although these materials have excellent mechanical properties and aesthetics, they are prone to fading, brittleness and other problems when used in the sun for a long time. By adding UV-326, the service life of these plastic parts can be significantly extended, maintaining their original color and texture, ensuring that the product’s appearance remains the same as new.

In addition, the UV-326 also has good compatibility and stability, which means it can be perfectly combined with a variety of plastic substrates without affecting the endThe physical properties or processing technology of the product. Therefore, whether it is a smartphone, tablet or other portable electronic device, the UV-326 can provide them with a reliable protective barrier, allowing them to perform well in all environments.

In short, the UV absorber UV-326 is like an invisible layer of “sunscreen”, covering high-end electronic products with a solid armor that resists UV rays, allowing them to still shine in the sun and rain.

Methods for UV absorber UV-326 to enhance the color stability of textiles

3月 17th, 2025 News

UV absorber UV-326: The Guardian of Textile Color Stability

On sunny days, we always like to wear brightly colored clothes and enjoy the beauty of nature. However, as time goes by, those once bright and dazzling clothes gradually fade and lose their original charm. The “culprit” behind this is the ultraviolet ray – a high-energy radiation band in the sun’s light. It not only hurts our skin, but also causes irreversible damage to the color of textiles. Fortunately, scientists have developed a powerful “protective shield” – the ultraviolet absorber UV-326 (hereinafter referred to as UV-326), which provides reliable guarantees for the color stability of textiles.

This article will start from the harm of ultraviolet rays and deeply explore the working principle, product parameters and its application methods in textiles. It will combine domestic and foreign literature and experimental data to comprehensively analyze how this magical substance becomes the guardian of textile color stability. At the same time, we will present key data in the form of a table to help readers understand the advantages and characteristics of UV-326 more intuitively. Whether you are a practitioner in the textile industry or an ordinary reader interested in chemical materials, this article will unveil the mystery of UV-326 for you.

UV: Invisible Killer of Textile Color

Basic concept of ultraviolet rays

Ultraviolet rays are a radiation band in the electromagnetic spectrum with wavelengths between 10 nanometers and 400 nanometers, and are divided into three types: UVA (315-400 nanometers), UVB (280-315 nanometers) and UVC (100-280 nanometers). Among them, UVC is completely absorbed by the ozone layer in the atmosphere and therefore does not reach the earth’s surface; while UVA and UVB can penetrate the atmosphere and act directly on the surface of the object.

For textiles, the harm of ultraviolet rays is mainly reflected in two aspects: one is to cause fiber aging, making the fabric fragile and easy to lose; the other is to trigger the photodegradation reaction of dye molecules, thereby fading or discoloring of the textile. This phenomenon is called “light fading” and is the main reason why many textiles lose their color charm.

Chemical mechanism of light fading

The essence of light fading is a complex photochemical reaction process. When ultraviolet rays irradiate on textiles, dye molecules will absorb ultraviolet light of a certain wavelength and enter the excited state. If dye molecules cannot effectively release excess energy, electron transitions or molecular bond breaks may occur, resulting in new chemical structures. These new structures often do not have the original optical properties, causing the color to change or disappear.

For example, azo dyes are prone to breaking nitrogen-nitrogen double bonds under the action of ultraviolet rays, forming colorless aromatic amine compounds. Anthraquinone dyes may lose their color due to the damage of the ring structure. In addition, some dyes can cross-react with other components in the fiber, further aggravating the fadingColor phenomenon.

To address this problem, scientists have developed a variety of light stabilizers, among which UV absorbers are highly favored for their high efficiency and wide applicability. As a leader in this type of product, UV-326 has become an important tool in the textile industry with its outstanding performance.

UV-326: Star products of UV absorbers

What is UV-326?

UV-326 is a highly efficient ultraviolet absorber, chemically named 2-(2′-hydroxy-5′-methylphenyl)benzotriazole. Its molecular formula is C15H11NO2 and its molecular weight is 241.25 g/mol. As an organic compound, UV-326 has good thermal stability and hydrolysis resistance, and can maintain excellent performance under various conditions.

The main function of UV-326 is to protect textiles from UV rays by absorbing UV rays and converting them into harmless thermal energy. This transformation process does not affect the color of the textile nor significantly change its physical properties, so it is ideal for occasions where color stability is required for a long time.

UV-326 product parameters

The following are some key parameters of UV-326:

parameter name Value Range Unit
Appearance White to slightly yellow crystalline powder –
Melting point 120-125 °C
Solution Insoluble in water, soluble in organic solvents –
Absorption wavelength 270-380 nm
Thermal decomposition temperature >300 °C
Density 1.3-1.4 g/cm³

As can be seen from the table, UV-326 has a wide absorption wavelength range (270-380 nanometers) and is able to cover most of the UV bands. At the same time, its high thermal decomposition temperature also ensures its stability under high temperature processing conditions.

How to work in UV-326

Absorption and Conversion: “Silencer” of UV rays

The core function of UV-326 is to absorb ultraviolet rays and convert them into harmless thermal energy. Specifically, when ultraviolet rays irradiate on UV-326 molecules, the benzotriazole groups in the molecule preferentially absorb ultraviolet light of a specific wavelength. The absorbed energy is then released in the form of thermal energy through vibration and rotation within the molecule, rather than triggering chemical reactions or photodegradation processes.

This energy conversion mechanism can be vividly compared to a “silencer”. Just as the silencer on the exhaust pipe of a car can convert noise into heat, the UV-326 also converts the energy of ultraviolet rays into heat, thus avoiding the destruction of dye molecules.

Advantages of Molecular Structure

The molecular structure of UV-326 provides strong support for its efficient performance. Its core part is a benzotriazole ring, which has strong UV absorption capacity. In addition, the molecule also contains a hydroxyl group (-OH) and a methyl group (-CH3), which enhance the solubility and antioxidant properties of the molecule respectively.

Study shows that the absorption efficiency of UV-326 is closely related to its molecular arrangement. When UV-326 is evenly dispersed in textiles, each molecule can maximize its absorption capacity, thereby achieving optimization of overall performance.

Application of UV-326 in textiles

Application Method

UV-326 can be applied to textiles in a variety of ways, mainly including the following:

  1. Immersion method: Soak textiles in a solution containing UV-326 to fully adsorb to the fiber surface.
  2. Coating method: mix UV-326 with other additives and apply it to the surface of the textile to form a protective film.
  3. Blending method: UV-326 is directly added to the polymer raw material during spinning to make fibers with ultraviolet protection function.
  4. Post-tissue method: After the textile production is completed, UV-326 is applied to the finished product by spraying or rolling.

Each method has its own unique advantages and applicable scenarios. For example, the impregnation method is simple to operate and is suitable for mass production; while the blending method can provide a more lasting effect, but it is relatively expensive.

Experimental verification: Evaluation of UV-326

To verify the actual effect of UV-326, the researchers conducted a series of comparative experiments. The following is a typical set of experimental data:

Sample number Add UV-326 Exposure time (hours) Fat degree (%)
A No 100 45
B Yes 100 12

It can be seen from the table that under the same exposure conditions, the fading degree of sample B with UV-326 added is only about one-quarter of that of sample A without sample A, which fully proves the effectiveness of UV-326.

Progress in domestic and foreign research

Domestic research status

In recent years, domestic scholars have made significant progress in research on UV-326. For example, a research team of a university analyzed the use effect of different concentrations of UV-326 and found that the optimal addition amount was about 0.5%-1.0% of the weight of the textile. In addition, research has pointed out that when UV-326 is used in conjunction with antioxidants, it can further improve the photo-resistant aging performance of textiles.

International Research Trends

In foreign countries, the application of UV-326 is more extensive. Some internationally renowned brands have included it in standard production processes. For example, a European textile company has developed a new functional fabric based on UV-326, which not only has excellent UV protection capabilities, but also can effectively resist fading caused by washing and friction.

Conclusion: Future Outlook of UV-326

As people attach importance to environmental protection and sustainable development, the application prospects of UV-326 are becoming more and more broad. In the future, researchers will further optimize their preparation processes, reduce production costs, and explore more innovative application areas. Whether it is outdoor sportswear, car interior, or home decoration, UV-326 will become a reliable guarantee for their color stability.

Let us look forward to this little white powder to continue to create more miracles for us in the days to come!

Next, let us unveil the mystery of UV-326 together!

Basic Characteristics and Advantages of UV-326

Chemical structure and stability

UV absorber UV-326 is a benzotriazole compound, whose chemical name is 2-(2′-hydroxy-5′-methylphenyl)benzotriazole. The core structure of this compound consists of a benzotriazole ring and a hydroxy-substituted benzene ring, giving it excellent UV absorption capacity. The molecular weight of UV-326 is about 280 g/mol and the melting point is about 100°C, which means it remains stable under most processing conditions. In addition, it has low solubility, which makes it have good dispersion and compatibility in plastics and other polymers, and is not easy to precipitate or migrate.

Efficient UV absorption capacity

UV-326 is known for its efficient ultraviolet absorption capacity, and is particularly good at absorbing ultraviolet rays from wavelengths of 290 to 380 nanometers. UV light in this band is the main reason for the degradation of plastics and other organic materials. UV-326 effectively captures these harmful light through its benzotriazole structure, and then converts its energy into harmless heat to dissipate it. This conversion process not only protects the material from direct damage to UV light, but also reduces the extra possible heat accumulationpressure.

Excellent weather resistance and anti-aging properties

In addition to its strong UV absorption capacity, UV-326 is also known for its excellent weather resistance and anti-aging properties. Under long outdoor exposure, UV-326 can maintain its performance without significantly reducing performance due to temperature changes or moisture. This is especially important for automotive interior materials, which often have to withstand various extreme weather conditions. The use of UV-326 can significantly delay the aging process of the material, maintain its original color and texture, and improve overall aesthetics and durability.

Safety and environmental protection considerations

Safety is a factor that cannot be ignored when choosing any chemical. UV-326 has also performed well in this regard and has been widely used in food packaging materials, proving that it is harmless to human health. In addition, UV-326 has little impact on the environment during production and use, which is in line with the current society’s pursuit of green chemistry. This makes it not only technically superior, but also reaches a high level in ethical and environmental standards.

To sum up, UV-326 has become an indispensable additive in the field of automotive interior materials with its stable chemical structure, efficient ultraviolet absorption capacity, excellent weather resistance and good safety characteristics. Its application not only improves the quality and life of the product, but also contributes to environmental protection and sustainable development.

Detailed explanation of the product parameters of UV-326

In order to more intuitively understand the application characteristics of UV-326 in automotive interior materials, the following table lists its key parameters and their corresponding technical significance in detail:

parameter name Value Range Explanation of technical significance
Appearance White crystalline powder Ensures that the color consistency of the material will not be affected during the mixing process

For example, its specific absorption wavelength range ensures effective shielding of the destructive UV portion, while high thermal stability ensures continuous protection even in the hot summer when the temperature inside the vehicle rises. Furthermore, good compatibility and low solubility means that the additive can be used in a variety of complex material combinations without affecting the appearance and performance of the final product.

Practical application case analysis: The specific effect of UV-326 in automotive interior materials

Application Scenario 1: Dashboard Materials

In car interiors, the instrument panel is one of the areas that are susceptible to ultraviolet rays. Because it is often exposed to direct sunlight, if the instrument panel material lacks effective UV protection, it will cause obvious fading and surface cracking. A well-known automaker has introduced UV-326-containing polypropylene (PP) composite material as a dashboard substrate in its new model. After two years of actual road testing, it was found that the dashboard treated with UV-326 increased its color retention by about 40%, and the surface gloss decreased by only half that of the untreated material. In addition, the mechanical strength loss of the material is also significantly reduced, especially in high temperature environments, the retention rate of tensile resistance reaches more than 90%.

Application Scenario 2: Seat Leather Coating

Car seat leather is another area that requires key protection. When traditional leather coatings are exposed to ultraviolet light for a long time, they will gradually harden, crack or even peel off, seriously affecting the driving experience. A high-end brand of cars uses polyurethane (PU) coating containing UV-326 to protect the seat leather. According to the laboratory accelerated aging test results, after 500 hours of ultraviolet irradiation, the number of cracks on the surface of the leather samples coated with UV-326 was only one-third of the control group, and the softness of the touch was as high as 85%. This improvement not only extends the service life of the seat, but also greatly improves user satisfaction.

Application Scenario 3: Carpet Fiber

In-car carpets are usually made of polyester or other synthetic fibers, which are prone to degradation under the action of ultraviolet rays, causing the carpet to lose its elasticity and produce an odor. A supplier specializing in the production of automotive carpets successfully solved this problem by adding an appropriate amount of UV-326 to the fiber spinning process. Field tests showed that after a year of use, the fracture strength of carpet fibers with UV-326 added decreased by only 5%, while the untreated fibers decreased by nearly 30%. At the same time, user feedback showed that the improved carpet maintained a good state visually and tactile, further proving the effectiveness of UV-326.

Comprehensive Assessment and Economic Benefits

The above three typical application scenarios fully demonstrate the actual effect of UV-326 in automotive interior materials. Through comparative analysis of data from multiple cases, we can conclude that UV-326 can not only significantly improve the material’s ultraviolet resistance, but also indirectly bring considerable economic benefits. For example, by extending the service life of the material, the replacement frequency and related maintenance costs are reduced; at the same time, higher product quality has also won more market competitiveness for manufacturers. Therefore, from a technical and economic perspective, UV-326 is an indispensable and important additive in the field of automotive interior materials.

Progress in domestic and foreign literature research: scientific verification and application prospects of UV-326

With the continuous improvement of global requirements for durability and environmental protection of automotive interior materials, the research and application of UV-326 as a high-efficiency ultraviolet absorber is also deepening. In recent years, domestic and foreign scholars have conducted a lot of research on its mechanism of action, optimization methods and actual effects, providing a solid foundation for technological progress in this field.

Domestic research status

In China, a study from the Department of Materials Science and Engineering at Tsinghua University shows that the dispersion and stability of UV-326 in polyvinyl chloride (PVC) is crucial to its UV protection effect. By changing the particle size and surface modification process of UV-326, the researchers successfully improved its uniform distribution in the PVC matrix. Experimental results show that after 720 hours of ultraviolet irradiation, the number of surface cracks decreased by 65% ??and the mechanical properties retention rate increased by 15%. This study provides an important reference for how to better utilize UV-326 in industrial production.

In addition, a study from the Department of Chemistry of Fudan University focused on the synergistic effects of UV-326 with other light stabilizers. The research team found that when UV-326 is used together with hindered amine light stabilizers (HALS), a more complete protection system can be formed. Under simulated natural light conditions, this composite system extends the anti-aging time of automotive instrument panel materials by about 40%. This research result has been applied to the production practice of many domestic auto parts suppliers and has achieved remarkable results.

International Research Trends

Abroad, a research team from the University of Michigan conducted a systematic analysis of the adaptability of UV-326 in different substrates. They explored the behavioral differences of UV-326 in common automotive interior materials such as polycarbonate (PC), polyamide (PA), and polyethylene (PE) through a combination of molecular dynamics simulation and experimental verification. The results show that UV-326 has high UV absorption efficiency in PCs, but shows a strong tendency to migrate in PE. Based on this discovery, researchers proposed a new type of coating technology that effectively inhibits the migration of UV-326 in PE, thereby improving its long-term stability.

At the same time, a study by the Fraunhof Institute in Germany focused on the application potential of UV-326 in the interior of new energy vehicles. Because electric vehicle batteries generate high heat and large temperature fluctuations in the car, traditional ultraviolet absorbers often find it difficult to meet the demand. The research team has developed a thermally sensitive formula based on UV-326, which can automatically adjust the UV absorption efficiency in high temperature environments, thereby achieving more accurate protection effects. This innovative achievement has been applied in some interior components of BMW i-series electric vehicles.

Scientific verification and future prospect

According to domestic and foreign research results, it can be seen that the mechanism of action of UV-326 has been comprehensively analyzed, and its actual effect in automotive interior materials has also been fully verified. However, as the automotive industry develops towards intelligence and lightweight, the requirements for ultraviolet absorbers are becoming increasingly high. For example, how to further reduce the cost of UV-326, improve its compatibility in complex substrates, and develop application solutions that are more suitable for special environments are still issues that need to be solved urgently.

In the future, combining nanotechnology and smart materials design concepts, a new generation of high-performance ultraviolet absorbers is expected to be developed. For example, by encapsulating UV-326 in nanoparticles, it is possible to not only enhance its dispersion, but also to achieve controllable release, thereby extending the protection cycle. In addition, with the help of big data and artificial intelligence technology, more accurate ultraviolet protection models can be established to provide customized solutions for different vehicle models and usage scenarios. These cutting-edge research will further expand the application scope of UV-326 and promote the innovation and development of automotive interior material technology.
