In modern society, outdoor sports have become one of the important ways for people to pursue a healthy life. Whether it is running, cycling or fitness, various sports equipment has become an indispensable companion. However, the appearance quality of these equipment often determines the first impression and willingness to buy. Among them, high-resilience castor anti-yellowing agent, as an emerging functional material, is quietly changing this field. This article will deeply explore the characteristics of high-resistance castor anti-yellowing agent and its application in improving the appearance quality of outdoor sports equipment, and reveal the technical mysteries behind it through rich data and case analysis.
1. Overview of high rebound castor anti-yellowing agent
(I) What is a high rebound caster anti-yellowing agent?
High resilience castor anti-yellowing agent is a functional additive specially designed for improving the performance of plastic products. It is mainly used in the manufacture of high-resistance casters based on polyurethane (PU), thermoplastic elastomer (TPE), etc., and aims to solve the problem of yellowing caused by ultraviolet rays, high temperatures or oxidation. This phenomenon not only affects the aesthetics of the product, but also may reduce its performance, thereby shortening its service life.
Simply put, anti-yellowing agent is like a “invisible guardian”. It can effectively prevent or delay the color changes of plastic products due to external environmental factors, making the product always bright as new. This characteristic is particularly important for outdoor sports equipment, which usually require prolonged exposure to sunlight, and UV rays are one of the main culprits in the yellowing of plastic products.
(II) Working principle of anti-yellowing agent
The core mechanism of action of anti-yellowing agents can be divided into the following two aspects:
-
Absorb UV rays
The UV absorber component in the anti-yellowing agent can efficiently absorb ultraviolet energy in the wavelength range and convert it into harmless heat to release it, thereby avoiding the damage of ultraviolet rays to the plastic molecular chain. -
Inhibit free radical reaction
Under high temperature or light conditions, free radicals are easily generated inside the plastic, which in turn triggers an oxidation reaction and leads to yellowing. Anti-yellowing agents prevent the material from damage by capturing these free radicals.
(III) Market status and development trends
In recent years, with the increase in global environmental awareness and the growth of consumers’ demand for high-quality products, the market demand for anti-yellowing agents has continued to expand. According to relevant statistics, the global anti-yellowing agent market size has reached billions of dollars in 2022, and is expected to grow at an average annual compound growth rate of more than 5% in the next five years. Especially inIn the sports goods industry, due to the high requirements for weather resistance and aesthetics of outdoor sports equipment, the application prospects of anti-yellowing agents are particularly broad.
2. Product parameters of high rebound castor anti-yellowing agent
In order to better understand the actual performance of high-resistance castor anti-yellowing agent, we can describe it in detail through the following key parameters:
| parameter name | Unit | Typical value range | Note Notes |
|---|---|---|---|
| Ultraviolet absorption efficiency | % | 90%-98% | Indicates the ability to absorb ultraviolet rays |
| Thermal Stability | ? | >200 | Stable performance can be maintained under high temperature environments |
| Compatibility | – | Good | Compatible with various polymer systems |
| Additional amount | phr | 0.5-2.0 | Number of parts added per 100 parts of resin |
| Yellow Index Improvement Rate | % | ?70% | Effect of improving the degree of yellowing |
From the table above, it can be seen that the high rebound caster anti-yellowing agent has high UV absorption efficiency and thermal stability, and can provide reliable protection in extreme environments. At the same time, its good compatibility also makes it suitable for a variety of different types of plastic substrates, meeting diverse needs.
3. Application of high rebound castor anti-yellowing agent in outdoor sports equipment
(I) Treadmill Casters
As a star product in home fitness equipment, the casters of treadmills not only need to have excellent wear resistance and silent performance, but also to withstand the test of sun and rain. Without effective anti-yellowing measures, the surface of the caster may gradually turn yellow or even crack, seriously affecting the overall appearance and user experience.
The weather resistance of casters can be significantly improved by adding an appropriate amount of high rebound casters anti-yellowing agent. For example, after a well-known brand of treadmill manufacturer used a modified polyurethane material containing anti-yellowing agent in its new product, it found that after a year of outdoor use testing, the color of the casters had almost no changes and the rolling resistance remained within the ideal range.
(II)Car foot support
For bicycle enthusiasts, although foot support seems inconspicuous, it is one of the important components to ensure riding safety. Traditional metal foot braces are prone to rust and corrosion, while plastic foot braces have the problem of yellowing and aging. To this end, many high-end bicycle brands have begun trying to use engineered plastics with anti-yellowing agents to make foot support.
Study shows that this type of improved foot supports have significantly improved impact strength, hardness and color durability. Even under direct sunlight, it can maintain its original bright color for a long time.
(III) Fitness equipment slide rail
Large equipment in the gym, such as rowing machines, strength trainers, etc., are usually equipped with a slide rail system for smooth movement. However, due to the long-term high-strength use, the surface of the slide rail will inevitably suffer from wear and fading. This not only affects the overall beauty of the equipment, but may also bring safety risks.
In response to this problem, some advanced fitness equipment manufacturers have introduced high-performance composite materials containing anti-yellowing agents, successfully solving the above problems. Experimental results show that after thousands of cycles of tests, the slide rails using this technology can still maintain a smooth and flat surface and show excellent anti-yellowing properties.
IV. Comparison of domestic and foreign research progress and technology
(I) Foreign research results
On an international scale, European and American countries have started research on yelping agents early and have accumulated rich experience and achievements. For example, BASF, Germany has developed a new anti-yellowing agent based on silicone structures, and its unique molecular design gives the product better heat resistance and light stability. In addition, DuPont, the United States has also made breakthrough progress in this field. The series of anti-yellowing products they launched have been widely used in aerospace, automobile industry and other fields.
(II) Domestic development status
In recent years, with the rapid development of my country’s chemical industry, the technical level of local enterprises in the field of anti-yellowing agents has been continuously improved. The research team represented by the Institute of Chemistry, Chinese Academy of Sciences has achieved a series of important results in the preparation of nano-scale anti-yellowing agents. These new technologies not only improve product performance indicators, but also greatly reduce production costs, laying the foundation for large-scale promotion and application.
However, compared with the international leading level, there is still a certain gap in the research and development and industrialization of high-end anti-yellowing agents in my country. Specifically, problems such as insufficient independent innovation capabilities of core technologies; some key raw materials rely on imports; and product quality consistency needs to be further improved, etc. Need to be solved urgently.
5. Future prospects and challenges
