PVC抗冲击改性剂 PVC impact modifier (塑改性氯化聚乙烯 CPE-135A（国标）) (Plastic modified chlorinated polyethylene CPE-135A (national standard))
产品简介 Product Introduction
CPE即氯化聚乙烯，由高密度聚乙烯（HDPE）经氯化而制得的，即用氯原子部分取代HDPE分子链上的氢原子的产物。 CPE stands for chlorinated polyethylene, which is made by chlorination of high-density polyethylene (HDPE), which is the product of partially replacing the hydrogen atoms on the HDPE molecular chain with chlorine atoms.
