Information

Chinese name: Chlorinated Polyethylene English name: Chlorinated Polyethylene Structural formula: [CH2-CHCl-CH2-CH2 ]n Abbreviation: CPE or CM Chlorinated polyethylene (CPE) is a saturated polymer material with a white powder in appearance and non-toxic It is odorless, has excellent weather resistance, ozone resistance, chemical resistance and aging resistance, and has good oil resistance, flame retardancy and coloring properties. Good toughness (flexibility at -30°C), good compatibility with other polymer materials, high decomposition temperature, decomposition to produce HCl, HCL can catalyze the dechlorination reaction of CPE. Chlorinated polyethylene is a polymer material made from high-density polyethylene (HDPE) through chlorination substitution reaction. According to different structures and uses, chlorinated polyethylene can be divided into resin type chlorinated polyethylene (CPE) and elastomer type chlorinated polyethylene (CM). In addition to being used alone, thermoplastic resins can also be blended with resins such as polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS, and even polyurethane (PU). In the rubber industry, CPE can be used as a high-performance, high-quality special rubber, and can also be combined with ethylene propylene rubber (EPR), butyl rubber (IIR), nitrile rubber (NBR), chlorosulfonated polyethylene (CSM), etc. Other rubbers are blended and used.
