有特殊紫外线稳定剂 with special UV stabilizers ; Extrusion- and injection molding grade ; Technical parts ; good low-temperature flexibility
与特殊的紫外线稳定剂 injection molding grade
紫外线稳定剂：虽然大量的太阳高能辐射已被大气层所吸收，然而 一些在280-400nm范围内的射线（紫外线）仍能达到地球表面。
Ultraviolet Stabilizers: While much of the sun's high-energy radiation is absorbed by the atmosphere, some radiation in the 280 to 400 nm (ultraviolet) range reaches the earth's surface.
根据光稳定剂作用机理的不同，将光稳定剂分为光屏蔽剂、紫外线吸收剂、激发态猝灭剂及自由基捕获剂。
Based on different action principle, light stabilizers were defined as ultraviolet light screening agent, ultraviolet absorbent, quencher and free radical catching agent.
主要用于聚氯乙烯不透明制品的稳定剂，其电绝缘性、耐候性及紫外线吸收性能良好。
It is mainly used as stabilizer for non-transparent PVC products, having excellent performance of electrical insulation, weather resistance and ultraviolet absorption.
