Chlorinated Polyethylene

Chlorinated Polyethylene CPE

MF: C21H42O4

CAS No.: 63231-66-3

Features:

1) Good anti-ageing property and excellent weatherability. It could be used under harsh climate and environment, and it is fully resistant to ozone
2)Good anti-combustion, no self-ignition
3)Good low-temperature flexibility. It could remain flexible under -20. 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
