This product is a polymeric high molecular weight hindered amine light stabilizer. It is an oligomer with good thermal stability during processing and good compatibility with various resins. Since this product is a high molecular weight compound, it has Very good resistance to water extraction, therefore, during processing or use, the resistance to water extraction is good and not easy to lose.

This product can effectively prevent the degradation of high polymers by light, heat, climate and moisture. It is much superior to the general low molecular weight hindered amine light stabilizer (HALS). Polymeric hindered amines have better heat resistance, resistance to extraction, and lower volatility and migration.

As a light stabilizer, this product is suitable for polyethylene, polypropylene, polystyrene, olefin copolymer, polyester, soft PVC, polyurethane, polyoxymethylene and polyamide, etc.
