UV 531 & Chimassorb 81 – Wellsorb UV-531
UV 531 & Chimassorb 81 is a light stabilizer with good performance, capable of absorbing the UV radiation of 240-340 nm wavelength with the characteristics of light color, nontoxic, good compatibility, small mobility, easy processing, etc. It can protect the polymer to its maximum extent, helps to reduce the color. It can also delay the yellowing and obstacle the loss of its physical function. It is widely applied to PE, PVC, PP, PS, PC organic glass, polypropylene fiber, ethylene-vinyl acetate, etc.
