Stabilizers for Weather Resistance Polyurethane

Fan Hua Wu Liangyi Ding Zhuming (Tianjin Synthetic Material Research Institute,300220)  
The stabilization mechanism of polyurethances were introduced. Some kinds of ultraviolet absorbents, light stabilizer, antioxidant used for polyurethane were summarized.The influences of ultraviolet (UV-571, UV-328), antioxidant (Irganox 1010,Irganox 1135,Irganox 3125), HALS light stabilizers (UV-770,UV-765)on improving light aging resistance properties of polyurethanes were discussed.The results show that using antioxidant, ultraviolet absorbent and HALS together have the best effect on maintaining light oxidative stabilization of polyurethanes.
