Light stabilizer UV120 is a benzoate light stabilizer with an ultraviolet absorption peak of 265 nm. It has the characteristics of low volatility, low coloration, good extraction resistance and high thermal stability. When used in combination with benzotriazole ultraviolet absorbers and nickel chelate light stabilizers, a significant synergistic effect can be achieved. When combined with antioxidants and hindered amines, it can form an excellent photo-oxidation stabilization system. It is suitable for polypropylene (film, flat yarn, injection molding), polyethylene, ABS resin, unsaturated resin, etc., and has excellent long - term thermal stability and light stability. The general dosage is 0.05 - 0.20%.
