UV-320 is a high-efficiency light stabilizer widely used in plastics and other organic materials, including unsaturated polyester, PVC, PVC plastic, etc., in polyurethane, polyamide, synthetic fiber, especially poly In the application of grease and epoxy resin, UV-320 effect is more prominent. UV-320 has the characteristics of strong UV absorption and low volatility. It can effectively protect polyester and organic pigments from ultraviolet radiation, thus protecting the original physical appearance of molded objects, film and the like in the open air.
Preparation or source:
(1) Extracted from coal tar.
(2) phenol and ethylene are used as raw materials, and phosphoric acid is used as a catalyst to obtain a reaction at 200 ° C and 4.0 to 4.5 MPa
