Product Description
Product Details
Introduction
Light stabilizer UV944 is a polymeric high molecular weight hindered amine light stabilizer. Its molecular structure contains multiple functional groups and has the dual functions of light stabilizer and antioxidant. It has the function of capturing free radicals generated by ultraviolet light and the long-lasting antioxidant performance of antioxidant. It has the characteristics of high temperature resistance, extraction resistance, low volatility, low migration, good thermal stability and high light stability.
Application
Applications include polyolefin plastics (such as PP, PE), olefin copolymers such as EVA, and blends of PP and elastomers. In addition, it can also be effectively used for polyoxymethylene (POM), polyamide (PA), polyurethane (PU), soft and hard PVC and PVC blends, and also has good effects on styrene elastomers and adhesives.
