The use of Chlorinated polyethylene
2023-06-19
At the end of the 1990s, the demand for high-performance flame retardant rubber in China was increasing, especially in the wire and cable industry and the development of auto parts manufacturing, which drove the demand for rubber-type Chlorinated Polyethylene. Rubber type Chlorinated polyethylene is a special synthetic rubber with excellent comprehensive performance, heat-resistant oxygen ozone aging and good flame retardancy. Chlorinated polyethylene resin is a new type of synthetic material with a range of excellent properties. It is an excellent impact modifier for PVC plastics. It is also a synthetic rubber with good comprehensive performance. It has a wide range of applications and has been widely used in cables, wires, hoses, rubber and plastic products, sealing materials, waterproofing membranes, films and Various kinds of 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. It has saturated molecular chains and random distribution of polar chlorine atoms. It has excellent physical and chemical properties and is widely used in machinery and electricity. , chemical, building materials and mining industries. CPE has better heat resistance, ozone resistance, weather resistance and aging resistance than most rubbers. Its oil resistance is better than that of nitrile rubber (NBR) and neoprene rubber (CR). Its aging resistance is better than that of chlorosulfonated vinyl chloride (CSM). Alkali, salt and other corrosive properties, non-toxic, no explosion hazard. It is mainly used in: wire and cable (coal used in coal mine cables, UL and VDE standards), hydraulic hoses, automotive hoses, tapes, PVC profile pipe modification, magnetic materials, ABS modification and so on.
