CPE 135B
CPE135B (Chlorinated Polyethylene 135B) is an amorphous saturated thermoplastic elastomer produced through the chlorination modification of high-density polyethylene (HDPE). It has an almost completely non-crystalline structure.This product combines the processing fluidity of plastics with the high elasticity of rubber, making it a high-performance specialty synthetic rubber material.
Product Introduction
CPE135B is a rubber-grade chlorinated polyethylene (CPE) produced through the chlorination modification of high-density polyethylene (HDPE). It is a thermoplastic elastomer with excellent flexibility, weather resistance, flame retardancy, and chemical stability.
CPE135B features low crystallinity, suitable Mooney viscosity, and excellent compatibility with various rubbers and plastics. It provides outstanding mechanical properties, low-temperature resistance, oil resistance, and aging resistance, making it widely used in wire and cable materials, rubber hoses, sealing products, and soft PVC applications.
Main Features
