Application: Uv320 is a high-efficiency light stabilizer, which is widely used in plastics and other organic compounds, including unsaturated polyester, PVC, PVC plasticizers, etc. uv320 has a more prominent effect in the application of polyurethane, polyamide and synthetic fiber, especially those resins with polyester and epoxy. Uv320 has the characteristics of strong ultraviolet absorption ability and low volatility. It can effectively protect polyester and organic pigments from ultraviolet radiation, so as to protect the original physical appearance of molded objects and films in the open air. Uv320 is slightly lighter than ordinary ultraviolet absorbers。
