Chlorinated polyethylene CPE-135B
Product Title：Chlorinated polyethylene CPE 135B is soft, flame-retardant, resistant to low temperatures, enhanced in oil resistance, and resistant to ozone.
product presentation：Chlorinated polyethylene is a high-molecular material obtained by the chlorination substitution reaction of high-density polyethylene (HDPE). Depending on its structure and application, chlorinated polyethylene can be classified into two major categories: resin-type chlorinated polyethylene (CPE) and elastic-type chlorinated polyethylene (CM). Besides being used alone, thermoplastic resins can also be mixed with polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS and even polyurethane (PU) resins. In the rubber industry, CPE can be used as a special rubber with superior performance and quality, and can also be mixed with other rubbers such as ethylene propylene rubber (EPR), butyl rubber (IIR), nitrile rubber (NBR), chlorosulfonated polyethylene (CSM), etc.
