Product DescriptionProduct DescriptionCPE ResinChlori nated Polyethylene (CPE) is a versatile thermoplastic polymer obtained by the chlorination of high-density polyethylene (HDPE). It exhibits a unique combination of flexibility, chemical resistance, and weatherability, making it suitable for a wide range of industrial applications. CPE is available in various grades, differentiated by chlo rine content, density, melt flow index, and particle size. The polymer is often supplied as fine powder or granular form for ease of processing.Key properties of CPE include:- Excellent impact resistance even at low temperatures- Good flexibility and elongation- Resistance to UV radiation, ozone, and weathering- Chemical and oil resistance- Compatibility with PVC, rubber, and other thermoplasticsProduct ParametersItemSpecificationsCAS Number63231-66-3Volatile Matter0.3–0.5Shore A Hardness57–65Chinese NameChlorinated Polyethylene ResinEnglish NameChlorinated PolyethyleneEnglish AbbreviationCPEDensity1.10-1.25 g/cm3Elongation at Break≥700ChIorine Content (%)35±2Tensile Strength8–15 MPaDecomposition Temperature≥165°CApparent Density (Bulk)0.45–0.55 g·cm-3Chemical NameChlorinated Polyethylene ResinAppearanceWhite free-flowing powder or granulesMooney Viscosity≤120Glass Transition Temperature (Tg)–15°C to –10°CApplication PVC ModificationCPE is commonly used to modify PVC to improve impact resistance, flexibility, and low-temperature performance. This is particularly valuable in producing rigid and semi-rigid PVC products like pipes, profiles, window frames, and siding.Wire and Cable InsulationCPE's excellent electrical insulation properties, combined with flexibility and resistance to weathering, make it ideal for use in power cables, control cables, and flexible cords. It enhances low-temperature flexibility and mechanical durability.Automotive ApplicationsIn automotive industries, CPE is used in weatherstrips, seals, bumpers, gaskets, and hoses. It provides excellent resistance to oils, fuels, and aging, while maintaining elasticity over time.Waterproofing MembranesCPE is widely employed in roofing membranes, waterproofing sheets, and geomembranes due to its water resistance, UV stability, and long-term durability. It maintains flexibility under extreme temperature variations. Flooring and Synthetic LeatherCPE is added to vinyl flooring, artificial leather, and coated fabrics to enhance flexibility, impact strength, and wear resistance.CPE can be blended with natural rubber, SBR, or EPDM to improve impact resistance, weatherability, and low-temperature performance. This is widely used in hoses, belts, and gaskets.Packaging & ShippingWe Offer Professional, Convenient And Efficient Packaging Services And a Variety Of Logistics And Shipping Services, Including Sea Freight, Air Freight, Express Delivery, Land Transport, Rail Transport And Door-To-Door Logistics Services.Company ProfileWeifang Phoenix New Material Co., Ltd.
