Thermoplastic Elastomer CPE 135A CAS 63231-66-3 PVC Impact Modifier Chlorinated Polyethylene

 

Chlorinated Polyethylene (CPE) is a type of thermoplastic elastomer produced by the chlorination of high-density polyethylene (HDPE). The chlorination process introduces chlorine atoms into the polymer chain, resulting in a material with enhanced properties and versatility.

Description:
CPE is a white or light-colored solid with a rubbery texture. It exhibits both thermoplastic and elastomeric properties, combining the flexibility of rubber with the processability of plastics. The degree of chlorination can vary, resulting in different grades of CPE with varying characteristics.

Applications:

1. Wire and cable insulation: CPE is commonly used as an insulation material for wires and cables due to its excellent electrical properties, resistance to chemicals and oils, and flame retardancy.
2. Automotive industry: CPE finds application in automotive components such as hoses, gaskets, seals, and weatherstripping. It provides good resistance to weathering, ozone, and chemicals, making it suitable for outdoor and under-the-hood applications.
3. Roofing membranes: CPE is used in roofing membranes to enhance their durability, flexibility, and resistance to weathering, UV radiation, and chemical exposure.
4. Impact modifiers: CPE is often used as an impact modifier in PVC (polyvinyl chloride) formulations. It improves the impact strength, low-temperature performance, and processing characteristics of PVC.
5. Adhesives and sealants: CPE is utilized in the formulation of adhesives and sealants to provide flexibility, adhesion, and resistance to environmental factors.

Features:

1. Flexibility and elasticity: CPE exhibits rubber-like flexibility and elasticity, allowing it to be easily molded and formed into various shapes. It can recover its original shape after deformation.
2. Chemical resistance: CPE demonstrates good resistance to chemicals, oils, greases, and solvents, making it suitable for applications where exposure to such substances is likely.
3. Weatherability: CPE possesses excellent resistance to weathering, UV radiation, and ozone, making it suitable for outdoor applications where exposure to harsh environmental conditions is expected.
4. Flame retardancy: CPE has inherent flame retardant properties, making it suitable for applications where fire resistance is required.
5. Processability: CPE can be easily processed using various methods such as extrusion, injection molding, and compression molding. It has good melt flow characteristics and can be blended with other polymers for improved performance.
