Product description

CPE (chlorinated polyethylene material) generally refers to chlorinated polyethylene. It is a saturated du polymer material. Its appearance is white powder, non-toxic and odorless, and has excellent weather resistance, ozone resistance, chemical resistance and resistance Aging performance, with good oil resistance, flame retardancy and coloring performance. Good toughness (flexibility at -30℃), good compatibility with other polymer materials, and high decomposition temperature.

According to different structures and uses, chlorinated polyethylene can be divided into resin-based chlorinated polyethylene (CPE) and elastomer-based 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).

Use

Chlorinated polyethylene has been widely used in products such as cables, wires, hoses, tapes, rubber and plastic products, sealing materials, flame-retardant conveyor belts, waterproof membranes, films and various profiles. CPE can also be blended with polypropylene, high and low pressure polyethylene, ABS, etc. to improve the flame retardancy, aging resistance and printing performance of these plastics.

CPE can be regarded as a random copolymer of ethylene, polyethylene and 1.2-dichloroethylene. Its molecular chain is saturated and polar chlorine atoms are randomly distributed. Because of its excellent physical and chemical properties, it is widely used in machinery and electricity. , Chemicals, building materials and mining industry.

CPE heat resistance, ozone resistance, weather resistance, and aging resistance are better than most rubbers, oil resistance is better than nitrile rubber (NBR), chloroprene rubber (CR), and aging resistance is better than chlorosulfonated vinyl chloride (CSM); acid resistance, Corrosive properties such as alkali and salt, non-toxic, non-flammable, and no explosion hazard.
