用途

(Application)

UV-329 具有十分有效的光稳定效果,可防止聚合物的泛黄和降解。可用于例如聚苯乙烯、聚烯烃、PVC、不饱和聚酯、丙烯酸树脂和ABS树脂。UV-329 能够单独使用,或与其他稳定剂配合使用。 UV-329 与受阻胺光稳定剂配合使用时,有协同效应。UV-329 的用量在 0.10-1.0% (A highly effective light stabilizer, it has a broad UV absorption spectrum and low volatility. For PS, polymethyl methacrylate, unsaturated polyester (UPE), rigid PVC, polycarbonate, ABS resin, etc., esp. in clear products or engineering plastics processed under high temperature. It has synergetic effect if used with antioxidant, which can raise heat and oxidization stabilities of the product. Usual amount to use is 0.01-1%.)
