Chlorinated polyethylene CPE 135A

Chlorinated Polyethylene (CPE) is a family of thermoplastic materials produced by chlorinating polyethylene. The process involves the introduction of chlorine atoms into the polyethylene polymer chain, which alters the material's properties, making it more flexible, durable, and resistant to oils, chemicals, and weathering.

CPE is characterized by its excellent impact strength, even at low temperatures, and its good resistance to heat, ozone, and chemicals. It also exhibits good electrical insulation properties and can be easily processed by extrusion, injection molding, and other thermoplastic processing methods.

The material is widely used in various applications, including:

1. **Wire and Cable Insulation**: Due to its excellent electrical insulation properties and resistance to environmental stress cracking.

2. **Automotive Parts**: Such as seals, gaskets, and hoses, where resistance to oils and chemicals is required.

3. **Construction Materials**: Including roofing membranes, waterproofing sheets, and window profiles, where durability and weather resistance are important.

4. **Industrial Hoses and Tubing**: Where flexibility and chemical resistance are needed.

5. **Footwear**: For soles and other components that require durability and flexibility.

CPE can be modified with other polymers or additives to enhance specific properties, making it a versatile material for a wide range of industrial applications. The degree of chlorination can be varied to produce materials with different properties, ranging from flexible elastomers to rigid plastics.

In summary, Chlorinated Polyethylene is a versatile and durable material that finds use in numerous industries due to its excellent combination of mechanical, chemical, and electrical properties.
