CPE（Chlorinated Polyethylene）

This product is composed of the structure of saturated, thermoplastic, almost no crystallization. It has very low mooney viscosity and plasticizing temperature, good processing property and has excellent performance mixed with natural rubber and synthetic rubber (for example CR, CSM, NBR, EPDM, SBR),which can give products with excellent weathering resistance, flexible, and flame retardant.
