【Summary Description 】 Chinese name: Chlorinated Polyethylene English name: chlorinated polyethylene Structural type: [CH2-CHCl-CH2-CH2]n English short name: CPE or CM Chlorinated polyethylene (CPE) is saturated polymer materials with white powder in the appearance.

Chinese name: Chlorinated Polyethylene English name: Chlorinated polyethylene Structure: [CH2-CHCl-CH2-CH2]n English abbreviation: CPE or CM chlorinated polyethylene (CPE) is a saturated polymer material, the appearance of white powder, non-toxic and tasteless, has excellent weather resistance, ozone resistance, chemical resistance and aging resistance, has good oil resistance, flame retardant and coloring properties. Good toughness (still flexible at -30℃), good compatibility with other polymer materials, high decomposition temperature, decomposition of HCl, HCL can catalyze the dechlorination reaction of CPE. Chlorinated polyethylene is a kind of high density polyethylene (HDPE) by chlorination. According to the different structure and use, chlorinated polyethylene can be divided into resin chlorinated polyethylene (CPE) and elastic type chlorinated polyethylene (CM) two categories. In addition to being used alone, thermoplastic resin can also be blended with polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS and even polyurethane (PU). In the rubber industry, CPE can be used as high performance, high quality special rubber, also can be mixed with ethylene propylene rubber (EPR), butyl rubber (IIR), nitrile butadiene rubber (NBR), chlorosulfonated polyethylene (CSM) and other rubber.
