What is Chlorinated Polyethylene(cpe)?

Chlorinated polyethylene for saturated polymer material, appearance is white powder, non-toxic tasteless, has excellent weather resistance, ozone resistance, chemical resistance and aging resistance, good oil resistance, flame retardancy and shading performance. Good toughness (in - 30 ℃ still have the flexibility), and other polymer material has good compatibility, decomposition temperature is higher.
English abbreviation: CPE or CM
Chlorinated polyethylene (CPE) as the saturated polymer material, appearance is white powder, non-toxic tasteless, has excellent weathering resistance, ozone resistance, chemical resistance and aging resistance, good oil resistance, flame retardancy and shading performance. Good toughness (in - 30 ℃ still have the flexibility), and other polymer material has good compatibility, high decomposition temperature, decomposition to produce HCL, HCL can catalytic dechlorination of CPE.
Chlorinated polyethylene is replaced by high density polyethylene (HDPE) by chlorination reaction of polymer materials. According to different structure and purpose, chlorinated polyethylene type can be divided into the resin chlorinated polyethylene (CPE) and elastic body of two kinds of chlorinated polyethylene (CM). Thermoplastic resin in addition to can be used alone, can also with polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS resin and polyurethane (PU) blend. In the rubber industry, CPE special rubber can be used as high performance, high quality, can also with ethylene-propylene rubber (EPR), butyl rubber (IIR), acrylonitrile butadiene rubber (NBR), chlorosulfonated polyethylene (CSM) and other rubber blend using.
