CPE Impact Modifier( CPE 抗冲改性剂)
Chlorinated PolyEthylene (CPE) is produced by combining chlorine and polyethylene in a process which is saturated. Linear high molecular structure enables CPE with superior physical and chemical performances.CPE has been widely used in plastics and rubber applications. CPE作为一种优良的、有着高性价比的抗冲改性剂,被广泛地应用于硬质塑料型材、管材、管件、板材等多种硬质塑料制品以及房屋外墙披叠板、建筑防腐、防潮薄壁板的生产。CPE能够促进PVC塑化,改善加工性能,并能大大提高制品的抗冲击强度,明显改善其耐低温及耐候等性能。
