Chlorinated polyethylene (CH2-CHCl-CH2-CH2)n is a polymer that has been treated with chlorine. It is used in a variety of applications, including electrical insulation, coatings, and adhesives. CPE is known for its high resistance to chemicals, heat, and UV light. It is also flame retardant and has good electrical properties.
CPE is used as a modifier for semi-rigid PVC wire harness.Improve low temperature properties (Brittle Temp. etc.) and Reduce the amount of plasticizer and prevent its bleeding.Loyal CPE Advantage: Flexibility, Weatherability, Heat aging resistance Flame retardancy and Chemical resistance.
Loyal CPE has high oil resistance and good heat resistance.
Loyal CPE is chlorinated elastomer. You have to put stabilizer(acid acceptor, antiaging agent) to prevent dehydrochlorination.
Don’t add heavy metal compounds like Iron or Zinc that accelerates degradation.

How do you make chlorinated polyethylene?
Chlorinated polyethylene can be made through two different processes, suspension chlorination and solution chlorination. In the suspension chlorination process, CPE is suspended in water and then treated with chlorine gas. This process is typically used to make lower density CPE products. In the solution chlorination process, CPE is dissolved in a solvent and then treated with chlorine gas. This process is typically used to make higher density CPE products.
What is CPE in PVC?
Chlorinated polyethylene (CPE) is a type of plastic that contains chlorine. It is used in a variety of applications, including as a liner for pipes and as a insulation material. CPE is also used in the production of PVC (polyvinyl chloride) products.
CPE is made by chlorinating ethylene, which is a type of hydrocarbon. The chlorine atoms attach to the ethylene molecules and create a new compound. The resulting material is then used to create products or improve the performance of existing products.
Loyal Chlorinated Polyethylene - 135A has been used for various applications of Wire & Cable.
Jacket/Seath of rubber Wire & Cable jacket
- Effective: Oil resistance, Heat resistance and Flame retardancy
Jacket/Seath of Insulated (Crosslinked) PE for Wire & Cable jacket
- Effective: Flame retardancy, Anti-drip and Electrical properties after water immersion
CPE has a number of benefits over other materials, including its resistance to chemicals, its flexibility, and its durability. It is also relatively inexpensive to produce.

Despite its many advantages, CPE has some drawbacks. It can be difficult to work with and it can emit harmful fumes when heated. Additionally, CPE is not recyclable and it can take centuries to break down in the environment.
If you have any questions about CPE or PVC, feel free to leave them in the comments section below.
Is CPE environmentally friendly?
CPE is made from PVC, which is a type of plastic. PVC is not biodegradable, so it will remain in the environment for a long time after it is thrown away. CPE is also not recyclable.
What does CPE mean in recycling?
CPE stands for chlorinated polyethylene. It is a type of plastic that is used in many different applications. CPE is recyclable and can be recycled into new products.
