Product Description
Chlorinated polyethylene (CPE, CPE 135A; CPE 135B and the various derivatives) is an inexpensive variation of polyethylene having a chlorine content from 34 to 44%. It is used in blends with polyvinyl chloride (PVC) because the soft, rubbery chlorinated polyethylene is embedded in the PVC matrix, thereby increasing the impact resistance. In addition, it also increases the weather resistance. Furthermore, it is used for softening PVC foils, without risking plasticizer migration. Chlorinated polyethylene can be crosslinked peroxidically to form an elastomer which is used in cable and rubber industry. When chlorinated polyethylene is added to other polyolefins, it reduces the flammability.
Application
CPE-135A is recommended to produce all kinds of opaque PVC products as PVC profiles, PVC fence, PVC pipe products, etc.
