Polyurethane shoe material anti-yellowing agent brings a long-lasting and fresh appearance to running shoes

Polyurethane shoe material anti-yellowing agent: a secret weapon to make running shoes last for a long-lasting and fresh appearance

In the world of running, a pair of running shoes is not only a companion for sports, but also a symbol of fashion. Just imagine, when you wear those brand new running shoes and run in the sun, its flawless whiteness, smooth lines and bright colors make you feel like you are the beautiful boy on this street? However, time is like a ruthless engraver, which will gradually dim the color of running shoes and even embarrassing “yellow changes”. At this time, polyurethane shoe material anti-yellowing agent became the hero to save the appearance of running shoes.

What is polyurethane shoe cotton anti-yellowing agent?

Polyurethane shoe material anti-yellowing agent is a chemical additive specially used to prevent color changes in polyurethane materials (such as soles, insoles, etc.) due to light, oxidation and other factors. It is like an invisible bodyguard, silently protecting your running shoes, keeping them fresh and beautiful at all times.

Basic Principles of Anti-Yellowing Agent

The mechanism of action of anti-yellowing agents is mainly divided into two categories: one is to prevent the occurrence of oxidation reactions by capturing free radicals; the other is to reduce the degradation reaction caused by light by absorbing ultraviolet rays. These two methods work together to effectively delay the aging process of polyurethane materials.

Market demand and application background

As people pay attention to sports health, the running shoe market has shown explosive growth in recent years. According to statistics, the global running shoes market size has exceeded US$30 billion, and this number is still rising. However, consumers’ requirements for running shoes are not only on functionality, but also their pursuit of aesthetics and durability is also increasing. Therefore, how to maintain the color stability of running shoes has become an urgent problem that major brands need to solve.

Status of domestic and foreign research

Domestic research progress

In China, research on anti-yellowing agents for polyurethane shoe materials started late, but developed rapidly. In recent years, with the rise of domestic running shoe brands, related technologies have also made great progress. For example, a university’s materials science laboratory has developed a new high-efficiency anti-yellowing agent, which has a performance comparable to imported products and is at a lower cost, providing strong technical support for domestic brands.

Frontier International Research

In contrast, international research on the fight against yelitising agents is more in-depth. Some well-known European and American companies have introduced nanotechnology and bio-based materials into the research and development of anti-yellowing agents, making the product’s performance more excellent. For example, a composite anti-yellowing agent launched by BASF, Germany, not only has excellent antioxidant ability, but also can significantly improve the weather resistance of the material.

Detailed explanation of product parameters

In order to better understand the actual effect of polyurethane shoe cotton anti-yellowing agent, let’s take a typical product as an example to list its parameters in detail.

parameter name Unit Specific value
Appearance Light yellow transparent liquid
Density g/cm³ 1.02-1.06
Viscosity mPa·s 50-80
Antioxidation properties % ≥95
UV absorption rate % ≥80
Thermal Stability ≤250

It can be seen from the table that this anti-yellowing agent performs excellently on multiple key indicators, especially its anti-oxidation performance of up to 95% and ultraviolet absorption of more than 80%, which is enough to cope with various complex usage environments.

Technical Advantage Analysis

Efficiency

Highly efficient anti-yellowing agents can achieve significant results at extremely low addition amounts. Generally speaking, just adding 0.5%-1.0% anti-yellowing agent can more than double the service life of polyurethane materials.

Safety

Safety is an important factor that must be considered when choosing anti-yellowing agents. Most modern anti-yellowing agents are environmentally friendly, do not contain any harmful substances, and are very friendly to the human body and the environment.

Economic

Although high-performance anti-yellowing agents are relatively expensive, they can greatly reduce maintenance costs and extend product life, resulting in higher economic benefits in the long run.

Applied case sharing

Case 1: A well-known brand of running shoes

A internationally renowned sports brand has adopted advanced polyurethane shoe anti-yellowing agent technology in its new running shoes. After a year of market feedback, the anti-yellowing effect of this running shoe is excellent, and it can still maintain a good appearance even in a high-strength environment.

Case 2: A new domestic brand

A emerging domestic running shoe brand has also introduced similar anti-yellowing technology in its new series. Through comparative tests, it was found that shoes using anti-yellowing agents performed better in color maintenance than those of the same shoes that were not used, and the user satisfaction was greatly improved.

Conclusion

In short, polyurethane shoe material anti-yellowing agent, as an important technological innovation, is changing our understanding of running shoes. It not only enhances the visual beauty of the product, but also enhances its practical value, truly realizing the perfect combination of technology and art. So, next time when you choose running shoes, you might as well pay more attention to whether it is equipped with this magical anti-yellowing technology! After all, who doesn’t want their love shoes to always maintain that first amazing thing?
