Chlorinated polyethylene(CPE)is a high molecular elastomeric material that is chlorinated by HDPE. It is white powder and innocuous. It has excellent anti-flaming, weatherability, lower-temperature flexibility and impact strength, etc. It can be blended with other plastics , mainly used as PVC impact modifier.
Feature:
High molecular weight;Good mechanical and physical properties;Great compatibility with PVC;
Excellent normal/low temperature impact strength due to formed 3D network structure in the correct processing conditions;
Commonly used as modifier plastic products or semi-finished plastics.
Use:
Mainly used in the manufacture of PVC window profiles,fence,board,housing folding board,wall panel,foam board,and U-PVC pipes.
