Chlorinated Polyethylene (CPE)

Formula: [CH₂–CHCl]ₙ GOST/CAS: CAS: 63231-66-3

Chlorinated Polyethylene (CPE) is a high-molecular thermoplastic material produced by the chlorination of high-density polyethylene (HDPE). Due to its unique structure, it combines the properties of both rubber and plastic. It is an essential impact modifier, providing PVC products with durability, frost resistance, and superior resistance to harsh atmospheric conditions.

Applications

PVC Industry: The primary impact modifier for window profiles, siding, pipes, panels, and fittings to enhance toughness and impact strength.

Cable Industry: Used as a jacketing material for wires and cables due to its excellent insulation and flame-retardant properties.

Rubber Products: Production of oil-resistant and heat-resistant hoses, conveyor belts, and seals.

Construction Materials: Manufacturing of roofing membranes and waterproofing sheets with high elasticity.

Key Advantages

Excellent Weatherability: Provides high resistance to UV radiation and oxidation, significantly extending the lifespan of outdoor products.

Chemical Stability: Resistant to acids, alkalis, and oils, maintaining physical properties even in aggressive environments.

High Compatibility: Blends easily with PVC and other polymers, significantly improving processability and tear strength.

Flame Retardancy: The chlorine content provides self-extinguishing properties, enhancing the fire safety of the finished products.

Storage & Transportation

Store in cool, dry, and well-ventilated warehouse facilities in original packaging.
Strictly avoid contact with direct sunlight and heat sources.
Do not stack under heavy pressure to prevent caking (clumping) of the powder.
Transport in covered vehicles, protecting the packaging from moisture and mechanical damage.
