Photostabilizer
Prolonging the Lifespan of High-Molecular Polymers
The photostabilizer is an essential additive in high-molecular polymer formulations. It prevents UV filters from losing effectiveness in sunlight, thereby extending the lifespan of the polymers.
Key Features
UV Protection: Prevents degradation of UV filters in sunlight.
Enhanced Durability: Prolongs the lifetime of high-molecular polymers.
Versatile Application: Suitable for various high-molecular polymer products.
