Weipren® CPE – Vinyl Modification & Thermoplastic Grades

Weipren® Chlorinated polyethylene (CPE) modifiers provide excellent impact resistance and ductility to the entire range of rigid PVC applications, including vinyl siding, fence, window profiles, and pipe. The range of use extends to PVC capstocks, based on proven weatherability of CPE-modified compounds. CPE also finds use in other thermoplastic applications, such as sheet, rigid foam, injection molded goods, and as a compatibilizer for polymer blends. Specialized CPE grades provide enhanced efficiency with an excellent combination of processing characteristics.
