Polyurethane TPE anti-yellowing agent: “color protection messenger” for plastic products

In the vast world of the plastic industry, polyurethane thermoplastic elastomer (TPE) is like a skilled craftsman, creating various plastic products. However, in these colorful plastic worlds, there is an invisible enemy – Huangbian, which quietly erodes the appearance and quality of plastic products. The protagonist we are going to introduce today – polyurethane TPE anti-yellowing agent, is the key weapon in this “color protection battle”.

What is polyurethane TPE anti-yellowing agent?

Definition and Function

Polyurethane TPE anti-yellowing agent is an additive specially designed to prevent yellowing of polyurethane thermoplastic elastomer (TPE) products. Its main function is to protect the color stability and physical properties of plastic products by inhibiting oxidation and photochemical reactions. Simply put, it is to keep plastic products “youthful and energetic” and not “grow old” due to the passage of time.

Working Principle

The working principle of the anti-yellowing agent is similar to putting a layer of “sun protection clothing” on plastic. It prevents chemical reactions that cause yellowing by capturing free radicals and decomposing peroxides. This not only extends the service life of plastic products, but also improves its market competitiveness.

Analysis on the influence of polyurethane TPE anti-yellowing agent on the quality of plastic products

Improving the appearance quality

Color stability

Plastic products without anti-yellowing agents are like white paper without umbrellas that tend to yellow in the sun. After using anti-yellowing agent, the color of the plastic products can remain bright for a long time, just like carefully cared for flowers, always blooming beautifully.

parameters	Description
Initial Color Index	≤2.0
Color index after aging test	≤5.0

Glossiness

Glossiness is as important to plastic products as the smoothness of the skin. Anti-yellowing agents can effectively prevent the loss of surface gloss and make plastic products look more high-end.

Improving physical performance

Tension Strength

Anti-yellowing agent not only protects the color, but also enhances the physical properties of the plastic. For example, treated plastic products have significantly increased tensile strength, which means they are more durable and can withstand the test of various usage environments.

parameters	Unit	Data
Tension Strength	MPa	≥18
Elongation of Break	%	≥450

Impact toughness

In the face of external impact, plastic products with anti-yellowing agents exhibit stronger toughness and are less prone to cracking or damage. This improvement is especially important for products that require frequent movement or collisions.

Extend service life

By effectively preventing yellowing, anti-yellowing agents greatly extend the service life of plastic products. This is of great significance to reducing resource waste and promoting sustainable development.

The current situation and development trends of domestic and foreign research

Domestic research progress

In recent years, domestic scholars have achieved many results in their research on the fight against yelitising agents. For example, a university team developed a new composite anti-yellowing agent that is better than traditional single-ingredient products. They verified the efficiency and economicality of the product through a large number of experiments.

International Frontier Trends

Internationally, some scientific research institutions in the United States and Europe are also actively exploring the application of new anti-yellowing agents. They have used nanotechnology and biotechnology to develop more environmentally friendly and efficient anti-yellowing solutions.

Conclusion

Polyurethane TPE anti-yellowing agent is not only a technological innovation in the plastics industry, but also an important guarantee for improving product quality. In the future, with the advancement of technology and changes in market demand, we have reason to believe that anti-yellowing agents will become smarter, more efficient and environmentally friendly, protecting the quality of plastic products. Let us look forward to more exciting developments in this field together!
