配方组成对UPVC异型材耐候性的影响

The Effect of Formula Design on the Weatherability of UPVC Profile

从配方角度研究不同UPVC异型材的耐候性,探讨了不同原料和助剂(PVC、稳定剂、钛白粉、冲击改性剂、CaCO3等)对异型材老化和长期耐候性的影响,并提出优化配方的要点。

The weatherability of UPVC profile was researched from formula viewpoint, especially the effect of different raw materials and additives （PVC, stabilizers, TiO2, anti-impact modifier, CaCO3 and so on）, were discussed, and how to optimize the formulation was also pointed out.
