Chlorinated Polyethylene Elastomer (CPE) from Canada
CPE is produced by chlorination of polyethylene, creating an elastomeric polymer of halogenated olefins in primary forms like powder or pellets under HTS 3904.90.1000. Chlorine modification imparts rubber-like properties with the base olefin structure preserved. Commonly used for wire insulation and roofing membranes.
