High molecular weight polymeric compound hindered amine light stabilizer HS-362
HS-362 is a high-performance polymeric hindered amine light stabilizer synergistic compound (HALS), which is especially suitable for polyolefin (PP,PE, polyolefin copolymer, nylon, polyacetal, polyester and other polymer products can effectively prevent the occurrence of photoaging phenomena, such as mechanical strength decline, yellowing, etc., and improve the weather esistance of products. This product can also be used for copolymers of polyolefin with EVA and PPO, polyoxymethylene (POM), nylon (PA), polyurethane (PU), soft and hard polyvinyl chloride (PVC) and PVC blends. In addition, this product also has good light stability effect on styrene, rubber and stickies. As a polymeric high molecular weight hindered amine light stabilizer,HS-362 has excellent compatibility with resin and extraction resistance, and can be used in systems requiring low volatilization and small migration. It is especially suitable for thin products such as film, flat wire and glass fiber
