CPE
Chlorinated polyethylene (PE-C or CPE) is an inexpensive variation of polyethylene, where chlorine is substituted for some of the hydrogen atoms. CPE has a chlorine content from 34 to 44%. Due to its soft, rubbery texture, CPE is added to polyvinyl chloride to increase its impact and weather resistance. Furthermore, it is used for softening PVC foils, without risking plasticizer migration.
