This product is a widely used polymeric high molecular weight hindered amine light stabilizer, which is effective by capturing free radicals and eliminating the harm of free radicals.Prevent the occurrence of photoaging. As an oligomer, the product has good processing thermal stability, good compatibility with various resins, good water extraction resistance, low volatility and low mobility, and more effectively prevents the degradation of polymers by light, heat, climate and moisture than ordinary low molecular weight light stabilizers.
This product can be widely used in copolymers of polyethylene, polypropylene, polystyrene and olefins, such as blends of EVA and polypropylene elastomer.
At the same time, polyurethane, polyoxymethylene, polyamide and polyester elastomer are used as stabilizers to prevent photoaging, and they also have high efficiency, which is superior to ordinary ultraviolet absorbers and nickel stabilizers. This product also has a good effect in ABS and other
