Application of foaming delay agent 1027 in biodegradable express packaging EPP foam and composting cycle control

1. Introduction: The appearance background of foaming delay agent 1027

In this era of “everything can be purchased online”, the express delivery industry has become an indispensable part of modern life. However, with the surge in express delivery business volume, the environmental problems brought about by traditional plastic packaging materials are becoming increasingly prominent. According to statistics, about one-third of the plastic waste generated worldwide every year comes from express packaging. These non-degradable plastic products can take hundreds of years to completely decompose in the natural environment, putting a heavy burden on the planet’s ecosystem.

Faced with this severe challenge, the research and development and application of environmentally friendly biodegradable materials have become the focus of global attention. Among them, EPP (Expanded Polypropylene) foam, as a buffer packaging material with excellent performance, has shown great potential in the field of express packaging due to its lightweight and strong impact resistance. However, to achieve truly environmental protection of EPP foam, the key is to solve the problems of its degradability and controllability in the production process.

It is in this context that the foaming retardant 1027 came into being. This new additive can not only effectively regulate the foaming process of EPP foam, but also significantly improve its degradability performance, making it compliant with the composting cycle requirements specified in the ASTM D6400 standard. This article will deeply explore the working principle, technical parameters and its application effect in EPP foam production, and combine it with new research results at home and abroad to analyze its importance in promoting the green transformation of express packaging.

Through the systematic explanation of this article, readers will have a comprehensive understanding of how foaming delay agent 1027 can achieve environmental protection goals while ensuring product performance, providing scientific basis and technical support for building a sustainable express packaging system.

Together these parameters constitute the complete technical system of foaming retardant 1027. Among them, the precise control of foaming delay time is one of the outstanding features of this product. It can effectively adjust the expansion rate of EPP foam and avoid product defects caused by excessive foaming. At the same time, biodegradation rates of up to more than 90% and composting cycles that meet ASTM D6400 standards ensure the environmentally friendly performance of the final product. In addition, good thermal stability and wide temperature resistance range enable the product to adapt to a variety of processing conditions and meet the needs of different application scenarios.

It is worth noting that there is a complex relationship between the various parameters of the foaming retardant 1027. For example, changes in the addition ratio will affect the foaming delay time and dispersion; the mixing temperature will change the compatibility coefficient and thermal stability. Therefore, in practical applications, the ratio of each parameter needs to be reasonably adjusted according to the specific formula design and process conditions to achieve excellent comprehensive performance.

3. Analysis of the mechanism of action of foaming retardant 1027

The reason why foaming retardant 1027 can be produced in EPP foamThe unique role of the system is mainly due to its clever molecular structure design and multifunctional synergy mechanism. The following is an in-depth analysis of the core working mechanism of this product from three aspects: chemical structure, mechanism of action and reaction kinetics.

(I) Chemical Structural Characteristics

Foaming retardant 1027 adopts a unique zwitterionic structure, consisting of hydrophilic and hydrophobic groups. This amphiphilic structure allows it to form good compatibility with the polymer matrix and to have specific interactions with the foaming agent. Specifically, its molecular backbone contains multiple ester and amide functional groups that not only provide the necessary polarity, but also impart excellent thermal and chemical stability to the product.

It is more worth mentioning that a specific biodegradation trigger unit is introduced into the foaming retardant 1027 molecule. These units remain stable under normal processing conditions, but can be rapidly catalyzed by microbial enzymes in a composting environment, thereby starting the entire material degradation process. This “intelligent switch” structural design allows the product to have controllable degradability while ensuring its performance.

(Bi) Analysis of the mechanism of action

The main functions of foaming retardant 1027 are reflected in the following aspects:

  1. Foaming rate regulation: By forming a weak hydrogen bond network with the foaming agent molecules, the diffusion speed of the foaming agent is reduced, thereby delaying the time of bubble nuclei generation. This gentle regulation method not only avoids pore unevenness caused by excessive foaming, but also ensures the mechanical properties of the final product.

  2. Crystal Nuclear Induction: Specific functional groups on the foaming retardant 1027 molecule can selectively adsorb in the crystallization region of the polymer matrix to form a stable crystal nuclear induction center. This not only improves the crystallinity of the foam material, but also improves its dimensional stability and compressive strength.

  3. Interface stabilization effect: With its versatile structure, the foam retardant 1027 can form a protective film at the gas-liquid interface to prevent excessive expansion or rupture of the bubbles. This interface stabilization effect is crucial to obtaining a uniform and dense foam structure.

(III) Research on reaction kinetics

Through kinetic monitoring of the foaming process, it was found that the addition of foaming retardant 1027 significantly changed the reaction rate constant of the system. Research shows that it mainly affects the reaction kinetics through the following two pathways:

  1. Activation Energy Regulation: The presence of foaming retardant 1027 increases the apparent activation energy of the foaming reaction and reduces the reaction rate to an appropriate range. This regulation effect is similar to the throttle valve in a car engine, and can be preciseConfirm the speed of the foaming process.

  2. Increased diffusion resistance: Due to the formation of the above-mentioned hydrogen bond network, the diffusion path of the foaming agent molecules becomes more tortuous, and the effective diffusion coefficient is significantly reduced. This “maze effect” further extends the foaming delay time and creates conditions for obtaining an ideal foam structure.

It is worth noting that the mechanism of action of the foaming retardant 1027 is not a single linear process, but a result of the joint action of multiple factors. For example, there is a synergistic effect between its crystal nucleus induction and interface stabilization, which promotes each other and jointly improves the overall performance of foam materials. In addition, the activation process of the biodegradation trigger unit of the product in the composting environment also follows a similar synergistic mechanism, namely, multiple enzymatic reactions are carried out simultaneously to ensure that the material is degraded within the specified time.

IV. Advantages of foaming retardant 1027 in EPP foam

The application of foam delaying agent 1027 in EPP foam production is like injecting a potentiator into the traditional foaming process. It not only solves many technical problems, but also opens up a new path for the development of green and environmentally friendly packaging materials. The following explains its unique advantages in detail from three aspects: product performance improvement, production process optimization and environmental benefits.

(I) Comprehensive improvement of product performance

The application of foaming retardant 1027 has significantly improved the performance indicators of EPP foam. First, by accurately controlling the foaming rate, the common pore uneven problem of traditional EPP foam has been successfully solved. Experimental data show that after adding foaming retardant 1027, the standard deviation of the pore size distribution of the foam material was reduced by 43%, and the porosity was increased by 18%, which directly improved the product’s buffering performance and thermal insulation effect.

Secondly, the unique crystal nucleus induction effect of foaming retardant 1027 greatly enhances the mechanical strength of EPP foam. Test results show that the compressive strength of the modified EPP foam has been increased by 35% and the tensile strength has been increased by 28%, which allows it to better cope with various impacts and squeezes that may occur during express transportation.

It is particularly worth mentioning that the addition of foaming retardant 1027 does not sacrifice the flexibility of the material. On the contrary, due to the micron-scale elastic network formed by its interface stabilization, the modified EPP foam still has good rebound performance while maintaining high strength. This characteristic of combining hardness and softness provides more possibilities for the design of express packaging materials.

(II) Innovation and optimization of production processes

In terms of production processes, the introduction of foaming retardant 1027 has brought about a revolutionary change. Traditional EPP foam production often requires expensive temperature control equipment to regulate foaming rates, and the use of foaming retardant 1027 greatly simplifies this process. By simply adjusting the amount of additives, i.e.Accurate control of foaming time can be achieved, which not only reduces the cost of equipment investment, but also improves the flexibility of the production line.

In addition, the good dispersion and compatibility of the foaming retardant 1027 significantly improves the uniformity of the raw material mixing. The ideal state that used to require multiple kneadings can now be achieved with just one operation. This process optimization not only saves energy consumption, but also shortens the production cycle and improves overall efficiency.

More importantly, the thermal stability of the foam retardant 1027 allows the EPP foam to be processed over a wider temperature range. This means that manufacturers can flexibly adjust processing conditions according to actual needs without worrying about product quality being affected. This improvement in process adaptability provides strong support for enterprises to explore new markets.

(III) Excellent environmental benefits

The remarkable advantage of foaming retardant 1027 is its excellent environmental performance. Through strict laboratory tests and verification, modified EPP foam can achieve a biodegradation rate of 92% in just 85 days under industrial composting conditions, far exceeding the requirements of the ASTM D6400 standard. This efficient degradation performance completely solves the environmental problems that traditional EPP foams are difficult to deal with.

More importantly, the foaming retardant 1027 itself uses renewable resources as raw materials, and the carbon emissions in the production process are only 40% of the traditional foaming agent. In addition, most of the carbon dioxide released during the composting process comes from biomass, which is carbon neutral emissions, truly achieving green and environmental protection throughout the life cycle.

To sum up, the foaming retardant 1027 not only performs outstandingly in product performance and production process, but also has won wide recognition in the market for its excellent environmental protection characteristics. The superposition of these advantages is driving the EPP bubble to develop in a more efficient, economical and sustainable direction.

5. Review and comparison analysis of domestic and foreign literature

The research and development and application of foaming delay agent 1027 has attracted widespread attention from the academic community at home and abroad, and the number of related research papers is showing an increasing trend year by year. By sorting out the core literature published in recent years, we can clearly see the research progress and future direction in this field.

(I) Current status of foreign research

European and American countries started early in the field of biodegradable foaming materials, and are in the leading position in both research depth and breadth. American scholar Smith et al. (2019) first proposed the “dynamic foaming window theory”, and revealed the influence mechanism of foaming delay agents on the microstructure of foam by establishing mathematical models. This theory points out that the role of the foaming retardant is essentially to dynamically adjust the position of the foaming window in the time-temperature coordinate system, so that the foaming process is more controllable. This research result provides a theoretical basis for the rational design of foaming delay agents.

The German research team Hoffmann et al. (2020) focused on optimizing the molecular structure of foaming retardants.They used quantum chemocomputing methods to systematically study the effects of different functional groups on foaming delay properties, and found that the introduction of specific carboxylic acid ester groups can significantly improve the thermal stability of the foaming delay agent while maintaining good biodegradability. This study provides an important reference for the molecular design of foaming retardant 1027.

Japanese scientist Tanaka et al. (2021) developed a foaming process prediction model based on machine learning from the perspective of industrial applications. This model can accurately predict the performance indicators of the final foam material based on process parameters such as the addition amount of foam retardant and mixing temperature. Practice has proved that the prediction accuracy of this model has reached more than 95%, greatly improving the controllability of the production process.

(II) Domestic research progress

Although my country’s research in the field of biodegradable foaming materials started a little later, it developed rapidly and has achieved many important results. Professor Li’s team at Tsinghua University (2020) took the lead in proposing a “multi-scale collaborative regulation strategy”, emphasizing the simultaneous optimization of the performance of foaming delay agents from the three levels of molecular, particle and macro. Through experimental verification, they found that the use of grading addition can effectively improve the dispersion and compatibility of the foam retardant agent, thereby improving the overall performance of the foam material.

Professor Zhang’s research group (2021) of Fudan University focuses on environmentally friendly research on foaming delay agents. They innovatively used natural plant extracts as raw materials for foaming delaying agents and successfully developed a series of bio-based products. These products not only have excellent foaming delay performance, but also release beneficial bacterial groups during the composting process and promote soil repair.

The team of researcher Wang from the Institute of Chemistry, Chinese Academy of Sciences (2022) conducted a large-scale industrial application test and systematically evaluated the applicability of foaming retardant 1027 in different types of EPP foams. The research results show that the product performs very well in high-density and low-density EPP foams, and can maintain stable performance especially in low-temperature environments.

(III) Comparative Analysis and Inspiration

By comparing domestic and foreign research results, it can be seen that foreign research pays more attention to breakthroughs in basic theories and exploration of cutting-edge technologies, while domestic research pays more attention to practical applications and industrial promotion. This difference reflects the different emphasis of the two countries in scientific research orientation. However, the two are not opposites, but complementary relationships.

The theoretical framework and calculation methods proposed by foreign research provide important guidance for domestic research, and the large amount of experimental data and practical experience accumulated in domestic research provide strong support for the improvement of theoretical models. Especially in the application study of foaming retardant 1027, this complementary effect is particularly obvious. For example, the research results of the German Hoffmann team on molecular structure optimization have been successfully applied to new product development by many domestic companies; and the multi-scale regulation strategy proposed by Professor Li’s team at Tsinghua University provides new research ideas for European and American peers.

It is worth noting that although domestic and foreign research has its own advantages, there are still differences on certain key issues. For example, the conclusions drawn by different studies are not completely consistent for the optimal addition ratio of foaming retardant. This reminds us that future research needs to strengthen international cooperation and form a more unified understanding through larger-scale experimental verification and data sharing.

Introduction to UL 2596 Vibration Test Standard

Before discussing how to conduct vibration testing of foaming retardant 1027, let’s first understand the basic content of the UL 2596 vibration testing standard. UL 2596 is a standard developed by Underwriters Laboratories to evaluate the performance and durability of various electrical and electronic devices and their components under mechanical stresses that may be encountered during transportation and use. This standard is particularly applicable to products that need to withstand high frequency vibrations, such as battery packs and accessories in new energy vehicles.

Purpose and importance of testing

The main purpose of the UL 2596 vibration test is to verify whether the product can maintain its structural integrity and functionality under long exposure to vibration conditions of different frequencies and amplitudes. For materials like foaming retardant 1027, this means ensuring that the buffer pad it supports can continue to effectively protect the battery pack from damage under complex road conditions. The importance of this kind of testing is that it is directly related to the safety of the vehicle and the quality of the user’s experience. If the buffer pad fails during vibration, it may cause damage to the battery pack, which will lead to serious safety accidents.

Key parameters specified by the standard

According to the UL 2596 standard, vibration testing involves multiple key parameters designed to simulate various conditions that a product may experience during its life cycle. The following are detailed descriptions of several main parameters:

parameter name Description
Vibration frequency range Tests usually start from low frequencies to high frequencies gradually increase to cover all possible resonance points.
Acceleration level indicates vibration intensity, unit in g (gravity acceleration). Different product categories have different requirements.
Duration The duration of the test for each frequency segment is generally in hours, depending on the expected usage environment.
Temperature Conditions In some cases, the test needs to be performed at specific temperatures to simulate extreme climatic conditions.

Home and foreign comparison and development trends

Across the world, in addition to UL 2596, there are other similar vibration testing standards, such as IEC 60068-2-6 and ISO 16750-3. Although these standards vary in details, the overall goal is to ensure sufficient reliability and safety of the product in the actual use environment. With the advancement of technology and changes in market demand, future vibration testing standards may be more stringent, and more environmental factors and user specific needs will be considered.

To sum up, UL 2596 vibration testing is not only an important link in product quality assurance, but also a key driving force for technological innovation and development. Through the understanding and application of this standard, we can better ensure the effectiveness and safety of foaming delay agent 1027 in new energy vehicles.

Physical and chemical properties of foaming retardant 1027

The reason why foaming delay agent 1027 can play an important role in the buffer pad of battery packs of new energy vehicles is closely related to its unique physical and chemical characteristics. These characteristics not only determine their effectiveness in practical applications, but also lay a solid foundation for them to pass the UL 2596 vibration test.

Physical Characteristics

Frost delay agent 1027 shows a series of characteristics that are conducive to improving the performance of the buffer pad. First of all, its moderate density can not only ensure good filling effect without significantly increasing the overall weight. Second, the material has a high elastic modulus, which means it can quickly return to its original state even when under high pressure, which is crucial for absorbing and dispersing vibration energy. In addition, foaming retardant 1027 also has a lower thermal conductivity, which helps to maintain the battery pack operating in a relatively stable temperature range and reduces the potential risks caused by temperature fluctuations.

Physical Characteristic Parameters Unit Typical
Density g/cm³ 0.03-0.05
Elastic Modulus MPa 1.2-1.8
Thermal conductivity W/m·K 0.02-0.04

Chemical Characteristics

Chemistry, the foaming retardant 1027 is known for its excellent chemical stability. It can remain stable within a wide pH range and is not prone to adverse reactions with other substances. This stability ensures that the material does not lose its efficacy due to chemical changes during long-term use. In addition, this material has good antioxidant ability, and can effectively inhibit the occurrence of oxidation reaction even under high temperature environments, thereby extending the service life of the buffer pad. More importantly, the foaming delay agent 1027 does not contain any known harmful substances and fully complies with the current international regulations and regulations on environmental protection and health and safety.

Chemical Characteristic Parameters Description
pH stability Stabilize between pH 4-10
Antioxidation capacity It can effectively inhibit oxidation reaction at high temperatures
Environmental Compliance Complied with international environmental standards such as REACH and RoHS

Influence on buffer performance

Combining the above physical and chemical characteristics, the foaming retardant 1027 has had a profound impact on the overall performance of the buffer pad. On the one hand, it improves the mechanical strength and wear resistance of the cushion, making it more resistant to the inevitable vibration and impact during daily driving; on the other hand, by improving thermal management and chemical stability, the adaptability of the cushion in harsh environments is further enhanced. These advantages work together to make the buffer pad using foam retardant 1027 show excellent performance in the UL 2596 vibration test, providing a reliable guarantee for the safety and comfort of new energy vehicles.

Step of Implementation of UL 2596 Vibration Test

After understanding the basic characteristics of foaming retardant 1027 and the importance of UL 2596 vibration test, we will discuss in detail how to implement this test in detail. The entire testing process can be divided into three main parts: preparation stage, execution stage and result analysis.

Preparation Phase

Equipment calibration and inspection

Before starting formal testing, it is a very important step to ensure that all equipment used is accurately calibrated. This includes a vibration table, a data acquisition system, and any auxiliary measurement tools. Calibration should be carried out in accordance with relevant international standards to ensure the accuracy and repeatability of test results.

Device Name Calibration cycle Calibration based standards
Vibration Test Platform Once a quarter ISO 10816-1
Data logger Once every six months IEC 60068-2-6
Temperature Controller Once per year ASTM E230/E230M

Sample preparation

The preparation of samples must be carried out strictly in accordance with the established specifications to ensure that the test results can truly reflect the performance of the material in actual applications. For foaming retardant 1027, this means integrating it into a complete buffer manufacturing process and then cutting into sizes and shapes that meet the test requirements.

Execution Phase

Vibration frequency and acceleration settings

According to UL 2596 standard, vibration tests should cover a range of frequency ranges and acceleration levels. Typically, the test starts at low frequencies (approximately 5 Hz), gradually increases to high frequencies (up to 500 Hz), and applies appropriate accelerations (such as 10g to 50g) at each frequency segment. Such a setup is to simulate the various vibrational conditions that a product may encounter throughout its life cycle.

Test environment control

In addition to mechanical vibration, the temperature and humidity of the test environment also need to be strictly controlled. This is because extreme environmental conditions may aggravate the aging or deformation of the material, thereby affecting the final test results. Generally, the test should be performed at room temperature (25°C ± 2°C) and at standard atmospheric pressure, but in some cases it may also require the introduction of high or low temperature cycles.

Result Analysis

After completing all predetermined vibration tests, the next step is to conduct in-depth analysis of the collected data. This step involves a comprehensive assessment of changes in the physical characteristics of the sample, surface damage, and internal structural integrity.

Data Processing and Statistical Analysis

Using advanced data analysis software, the original number can be transferredIt is translated into easy-to-understand forms such as charts and curve charts. Through these visualization tools, engineers can quickly identify which combinations of frequencies and accelerations have a big impact on the sample, thereby optimizing product design.

Product evaluation and improvement suggestions

After

, based on the above analysis results, specific performance evaluation reports and improvement suggestions are proposed. If poor performance is found under certain conditions, it may be necessary to adjust the formulation of foaming retardant 1027 or modify the overall structural design of the buffer pad. This feedback mechanism is an indispensable part of continuously improving product quality.

To sum up, UL 2596 vibration testing is not only a simple process of determining whether to pass or not, but also an opportunity to gain insight into the behavioral characteristics of materials and continuously optimize solutions. Through rigorous and meticulous implementation steps, we can ensure that every product can withstand the test of harsh reality.

Evaluation and data analysis of vibration test results

After completing all the steps of the UL 2596 vibration test, it is particularly important to conduct scientific and systematic evaluation and analysis of the test results. This not only helps to confirm whether the performance of the foaming retardant 1027 in actual applications meets expectations, but also provides a valuable reference for subsequent product optimization and technical improvement.

Initial Data Analysis

Preliminary data analysis is usually focused on several key indicators that can intuitively reflect the sample’s state changes during and after vibration testing. The first is the degree of deformation of the sample, which is a basic parameter to measure the stability of the mechanical properties of the material. If the sample exhibits significant deformation or cracks during the test, it indicates that its structural integrity is challenged and may require a reexamination of the material selection or processing process.

Initial Data Parameters Unit Typical values ??before testing Typical values ??after test
Flag variable mm 0 < 0.5
Mass loss rate % 0 < 1.0
Surface hardness change Shore A 45 > 40

Further performance evaluation

In addition to basic data comparison, deeper performance evaluation is also required. This includes, but is not limited to, the fatigue life, thermal stability and chemical stability of the materialSex and other aspects. For example, by observing the microstructure changes of the sample after a long period of vibration, it can be judged whether there is any hidden damage or deterioration inside it. In addition, using analysis methods such as infrared spectroscopy (FTIR) to detect whether the sample has an irreversible chemical reaction, which is crucial for safety assessment in long-term use.

Result Interpretation and Significance

This is not only a technical article, but also an in-depth exploration journey about the science and engineering practice of electronic materials.

2. Detailed explanation of UL 1449 standard: The significance and requirements of lightning strike withstand voltage test

UL 1449 standard, full name of “Surge Protector Safety Standard”, is a globally recognized surge protection equipment testing specification. Among them, 6kV lightning strike withstand voltage testing is undoubtedly one of the key and challenging projects in this standard. This test is designed to evaluate the ability of electronic devices and their protective materials to withstand lightning shocks, ensuring that the system can maintain normal operation under extreme conditions.

In the specific test process, the equipment needs to withstand a series of strict regulations: first, the test voltage must reach 6000 volts and be applied to the sample with a specific waveform; second, the entire test process must be carried out under strict environmental control, including temperature, humidity and other conditions, and afterwards, the sample needs to undergo multiple continuous impact tests, with the interval of no more than 1 minute. This high-intensity and high-frequency testing method fully simulates the real scene of lightning impact in nature.

It is of great significance to pass this test. It not only verifies the stability of the material under extreme conditions, but more importantly, it ensures the safety and reliability of electronic devices in the face of emergencies. Imagine that when a lightning bolt cuts through the sky and huge energy pours into the power grid instantly, it is these rigorously tested materials that silently protect our living facilities and data security.

3. Analysis of the performance parameters and advantages of TEDA materials

TEDA series of electronic potting materials has set a benchmark in the industry with its outstanding performance parameters and unique advantages. The following table shows the key performance indicators of TEDA’s main products:

parameter name TEDA-200 TEDA-300 TEDA-500
Density (g/cm³) 1.25 1.32 1.45
Hardness (Shore A) 45 58 72
Tension Strength (MPa) 6.5 8.2 9.8
Electrical Insulation Resistance (?·cm) >10^14 >10^15 >10^16

It can be seen from the table that the TEDA series products perform excellently in terms of density, hardness, tensile strength and electrical insulation properties. In particular, its electrical insulation resistance value is far exceeding the industry average, laying a solid foundation for 6kV lightning strike withstand voltage testing.

The unique advantages of TEDA materials are mainly reflected in the following aspects: First, its molecular structure has been specially designed and has excellent aging resistance. Experiments show that after continuous operation in high temperature and high humidity environment for 1,000 hours, the electrical performance degradation rate of TEDA materials is less than 5%, which is significantly better than similar products. Secondly, TEDA adopts advanced nanomodification technology, which greatly improves the impact resistance of the material. Research shows that the impact toughness of TEDA materials after nanomodified can be increased by more than 30% (reference: Zhang Wei, “Research on Polymer Material Modification Technology”, 2019).

In addition, TEDA materials also have good fluidity and permeability, and can effectively fill gaps of electronic components in complex shapes. This characteristic allows the material to form a uniform and dense protective layer after curing, further enhancing the protective effect.

IV. Performance of TEDA materials in 6kV lightning strike tolerance test

The TEDA series materials demonstrated impressive performance in actual 6kV lightning strike withstand voltage tests. To comprehensively evaluate its protective capabilities, the researchers designed a series of rigorous testing schemes covering different application scenarios and environmental conditions. The following are several typical test cases and results analysis:

In the first test case, the TEDA-300 material was used to package a high-performance power module. Test results show that after 20 consecutive 6kV shocks, the electrical performance of the module only dropped by 2.3%. It is particularly noteworthy that TEDA materials exhibit excellent thermal stability during impact, and their surface temperature increase is always within the safe range (Reference: Li Hua, “Research on Thermal Management of Electronic Materials”, 2020).

The second case involves the application of outdoor communication equipment. The researchers applied the TEDA-500 material to the package of an optical communication module. In tests simulated inclement weather conditions, the material maintained stable electrical properties even at temperature cycles from -40°C to 85°C. Experimental data show that the dielectric constant change rate of TEDA-500 is only 1.2%, far lower than the industry average (Reference: Wang Qiang, “Research on the Performance of Electronic Materials in Extreme Environments”, 2021).

The third case focuses on the protection needs of high-frequency electronic devices. TEDA-200 material performed well in high-frequency signal transmission tests, and its shielding effect on electromagnetic interference reached more than 98%. Especially after 100 6kV shock tests, the dielectric loss factor of the material increased by only 0.005, showing excellent long-term stability.

Through comparative analysis, it can be found that TEDA materials perform well in different application scenarios. Its unique molecular structure design and advanced production process enable it to effectively disperse energy in the face of lightning shocks while maintaining stable electrical performance.
