The chemical dictionary tells you what chlorinated polyethylene is and the uses of chlorinated polyethylene. With the increasing domestic demand for high-performance flame-retardant rubber, especially the development of wire and cable industry and auto parts manufacturing industry, Consumer demand for rubber-based CPE. So many people will ask: What is chlorinated polyethylene? What is chlorinated polyethylene
Chlorinated polyethylene (CPE) is a saturated polymer material, white powder in appearance, non-toxic and tasteless, with excellent weather resistance, ozone resistance, chemical resistance and aging resistance, and good oil resistance, flame retardancy and coloring performance. Good toughness (flexibility at -30℃), good compatibility with other polymer materials, high decomposition temperature, decomposition to produce HCL, HCL can catalyze the dechlorination reaction of CPE.
Chlorinated polyethylene use
Chlorinated polyethylene resin is a new type of synthetic material with a series of excellent properties. It is an excellent impact modifier for PVC plastics and a synthetic rubber with good comprehensive performance. It has a very wide range of applications and has been widely used in cables, wires, hoses, tapes, rubber and plastic products, sealing materials, and flame retardant conveyor belts. , Waterproof membranes, films and various profiles and other products. 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 distributed randomly. 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, Alkali, salt and other corrosive properties, non-toxic, non-flammable, no explosion hazard.
