Chlorinated polyethylene (CPE) is an innovative powder derived from the suspension chlorination of HDPE in a water phase. As chlorination progresses, crystalline HDPE transforms into an amorphous elastomer. This saturated polymer material appears as a white, non-toxic, and odorless powder. CPE boasts outstanding weather, ozone, chemical, and aging resistance, paired with excellent oil resistance, flame retardancy, and color properties. Its remarkable toughness and flexibility endure even at -30ºC. Additionally, CPE integrates seamlessly with various polymer materials and offers a high decomposition temperature, releasing HCL, which catalyzes its own dechlorination reaction.
Chlorinated polyethylene is a sophisticated polymer created through the chlorination substitution reaction of high-density polyethylene (HDPE). Depending on its structure and application, CPE is categorized into resin chlorinated polyethylene (CPE) and elastic type chlorinated polyethylene (CM). Thermoplastic resins not only stand alone but can blend with polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS, and even polyurethane (PU). In the rubber industry, CPE shines as a high-performance, special rubber, blending seamlessly with ethylene propylene rubber (EPR), butyl rubber (IIR), nitrile butadiene rubber (NBR), and chlorosulfonated polyethylene (CSM), among others.
In the late 1990s, the domestic market saw a surge in demand for high-performance flame-retardant rubber, spurred by the wire and cable industry and the automotive parts manufacturing sector. This demand significantly boosted the consumption of rubber CPE. Renowned for its exceptional properties, rubber-type CPE offers superb heat resistance, oxygen and ozone aging resistance, and notable flame retardancy, making it a unique synthetic rubber.
Chlorinated polyethylene resin represents a cutting-edge synthetic material known for its exceptional properties. It excels as an impact modifier for PVC plastic and serves as a high-performance synthetic rubber. With an extensive range of applications, CPE is utilized in cables, wires, hoses, tapes, rubber and plastic products, sealing materials, flame-retardant transport belts, waterproof membranes, films, and various profiles. Blending CPE with polymers like polypropylene, high and low-pressure polyethylene, and ABS enhances their flame retardancy, aging resistance, and printability. Widely used across machinery, electric power, chemicals, building materials, and mining industries, CPE's heat resistance, ozone and weather resilience, and aging resistance surpass most rubbers. Additionally, its oil resistance outperforms nitrile (NBR) and neoprene (CR), and its aging resistance exceeds that of chlorosulfonated polyethylene (CSM). Non-toxic, flame retardant, and devoid of explosion risks, CPE resists acids, alkalis, and salts.
Primarily used in: - Wire and cable (including coal mine cables, and those adhering to UL and VDE standards) - Hydraulic hoses - Automotive hoses - Tapes - Rubber plates - PVC profile pipe modifications - Magnetic materials - ABS modifications, and more.
