Description

Light stabilizer 622, also known as tinuvin 622, is a polymerized relatively high molecular weight hindered amine light stabilizer with a large average molecular weight, heat resistance, low volatility, migration resistance, easy processing, and low alkalinity. It has a synergistic effect when used together with antioxidants and UV absorbers, has excellent antioxidant effects, and has good compatibility with resins. Light stabilizer 622 can effectively prevent the degradation of products by light, heat, climate and moisture, and is better than general low molecular weight hindered amine light stabilizers. Light stabilizer 622 is mainly used in polyolefin materials. It can also be used in polyethylene, polypropylene, polyurethane, polyoxymethylene, polyacetal, soft polyvinyl chloride, polyamide, ABS and engineering plastics, especially for nylon 11 and nylon 12 and polyester elastomers. In addition, light stabilizer 622 is approved for food packaging in some countries.
