1. Introduction
CPE is the abbreviation of Chlorinated Polyethylene. It is made from HDPE and chlorine. Its appearance is white powder. Features as follows:
1) Good anti-aging property and excellent weatherability. It could be used under harsh climate and environment, and it is fully resistant to ozone
2) Good anti-combustion, without self-ignition
3) Good low-temperature flexibility. It could remain flexible under -20 degree Celsius. It may be used as impact modifier in UPVC product
4) Excellent endurance to chemicals. It is inert to many chemical reagents, and corrosion-resistant to various acids and alkalis
5) Good processing ability. It's easy to be shaped
6) Extremely safe for operation. CPE is harmless to human body and the environment
7) Excellent stability
