These mechanisms work together to form a strong defense line against yellowing, allowing sports shoes to remain as white as before after long-term use.

2. Application background of polyurethane shoe material anti-yellowing agent

With the booming development of the global sports industry, the demand for professional sports shoes has been increasing year by year. According to statistics from the internationally renowned market research institution Statista, global transportation in 2022The size of the sneaker market has reached US$95 billion and is expected to continue to grow at an average annual rate of 5%. However, in the fierce market competition, consumers’ requirements for sports shoes have long exceeded the basic functional needs, and instead pay more attention to the product’s appearance design and durability. Against this background, polyurethane shoe material anti-yellowing agent has emerged and has become an important tool for major brands to enhance product competitiveness.

(III) Market demand drives technological innovation

In recent years, consumers’ aesthetic standards for sports shoes have been increasing, and the trend of “little white shoes” has swept the world. This type of sneakers with white as the main color is popular for their simple and fashionable design style, but they are also facing serious yellowing problems. How to solve this pain point has become a technical problem that the shoemaking industry needs to overcome urgently. The emergence of polyurethane shoe anti-yellowing agent provides a perfect solution to this problem. It can not only significantly improve the color stability of the shoe material, but also be environmentally friendly and economical, satisfying the pursuit of green consumption concepts by modern consumers.

3. Product parameters of polyurethane shoe material anti-yellowing agent

In order to better understand the practical application effect of polyurethane shoe cotton anti-yellowing agent, we can reveal its excellent performance by conducting detailed analysis of its key parameters.

The above parameters show that polyurethane shoe anti-yellowing agent has extensive adaptability and excellent performance in practical applications. Its high thermal decomposition temperature ensures stability in the high-temperature molding process, while a moderate addition ratio takes into account cost control and effect optimization. At the same time, the high anti-yellowing index fully reflects the core value of the product.

IV. Review of domestic and foreign literature

Scholars at home and abroad have conducted in-depth discussions on the research results of polyurethane shoe cotton anti-yellowing agent. A paper titled “UV Stabilizers in Pol” published by the Journal of Applied Polymer Science in the American Chemical SocietyThe article in yurethane Foams for Shoe Sole Applications states that by introducing specific types of UV stabilizers into polyurethane foams, its anti-yellowing properties can be significantly improved. Experimental data show that after the treated shoe material was exposed to the sun for three consecutive months in a simulated outdoor environment, the degree of yellowing was only about 15% of the untreated samples.

At the same time, important progress has been made in research in related fields in China. A study from the School of Materials Science and Engineering of Tsinghua University shows that the use of a composite antioxidant system can further enhance the anti-yellowing effect of polyurethane shoes. Through comparative tests, the researchers found that the composite formula can increase the yellowing resistance index by about 20 percentage points compared to a single component, and has little impact on the mechanical properties of the materials.

In addition, a long-term follow-up survey by the Fraunhofer Institute in Germany showed that sneakers containing high-efficiency anti-yellowing agents perform well in actual use and maintain a good appearance even under extreme climate conditions. This fully demonstrates the reliability and effectiveness of polyurethane shoe anti-yellowing agent in practical applications.

5. Advantages and challenges of polyurethane shoe anti-yellowing agent

Although polyurethane shoe cotton anti-yellowing agent has shown great potential in the field of sports shoes, it still faces many challenges in its development process. On the one hand, due to the differences in production processes and technical levels between different brands, the actual application effects of anti-yellowing agents are uneven; on the other hand, as environmental protection regulations become increasingly strict, how to develop a greener and more environmentally friendly anti-yellowing agent has also become the focus of the industry.

(IV) Advantage Analysis

1. Significantly improve product life: By effectively suppressing yellowing, the service life of sports shoes is greatly extended and the frequency of replacement for consumers is reduced.
2. Enhance brand competitiveness: High-quality anti-yellowing performance helps to establish a brand image and attract more loyal users.
3. In line with the concept of sustainable development: The new generation of anti-yellowing agents are mostly made of renewable raw materials, reducing the impact on the environment.

(V) Challenge Response Strategies

In response to the above challenges, the industry generally takes the following measures to deal with them:

1. Strengthen investment in technology research and development: Carry out basic research with universities and research institutions to continuously optimize product formulas.
2. Establish a unified standard system: Promote the formulation of industry standards and ensure consistency in product quality.
3. Promote green production model: Encourage enterprises to adopt clean production processes to reduce wasteMaterial emissions.
