Chlorinated polyethylene（CPE）is a polymer material made from high-density polyethylene（HDPE）through chlorination reaction. It has good heat aging resistance, ozone and weathering resistance, oil and solvent resistance, electrical properties and flame retardancy. These characteristics of CPE make it an important rubber material in the wire and cable industry.

In the wire and cable industry, CPE is mainly used to manufacture cable sheath materials. Due to its heat resistance, the maximum operating temperature of CPE cable can reach 75-85℃, or even higher. CPE vulcanizate has excellent ozone and weathering resistance, can maintain stable performance under harsh conditions, and is not prone to cracking. In addition, CPE's oil resistance and chemical resistance make it show good stability in various oil and chemical environments.

Although the electrical properties of CPE limit its application in high-voltage insulation materials，its heat resistance, aging resistance and wear resistance make it an ideal material for cable sheaths. CPE's flame retardant properties are also very outstanding. It does not spread fire and can form an ash layer to prevent the spread of flames under the action of flames, thereby improving the safety of wires and cables.

In terms of processing technology, CPE can be cross-linked by high-temperature thermal cross-linking or electron irradiation, providing a variety of processing options. CPE has good processing performance, is easy to mix with other rubbers and plastics, and has good durability, which makes CPE widely used in the wire and cable industry.
