Chlorinated polyethylene (CPE) is a saturated polymer material with a white powder appearance, non-toxic and tasteless, excellent weather resistance, ozone resistance, chemical resistance and aging resistance, and good oil resistance, flame retardancy and coloring. performance. Good toughness (flexibility at -30 °C), good compatibility with other polymer materials, high decomposition temperature, decomposition to produce HCL, HCL can catalyze the dechlorination of CPE.
Chlorinated polyethylene is a polymer material obtained by high-density polyethylene (HDPE) by chlorination substitution reaction. Depending on the structure and use, chlorinated polyethylene can be divided into resin chlorinated polyethylene (CPE) and elastomeric chlorinated polyethylene (CM). The thermoplastic resin may be used alone or in combination with a resin such as polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS, or even polyurethane (PU). In the rubber industry, CPE can be used as a high performance, high quality specialty rubber, or with ethylene propylene rubber (EPR), butyl rubber (IIR), nitrile rubber (NBR), chlorosulfonated polyethylene (CSM), etc. Other rubber blends are used.
Chlorinated Polyethylene CPE CAS No. 63231-66-3 Feature
CPE is a kind of saturated rubber with excellent heat-resistant oxygen aging, ozone aging, acid and alkali resistance and chemical properties.
2) CPE has good oil resistance, among which ASTM No. 1 oil and ASTM No. 2 oil have excellent performance, which is equivalent to NBR; ASTM No. 3 oil has excellent performance and is superior to CR, which is equivalent to CSM.
3) CPE contains chlorine, has excellent flame retardant properties, and has anti-dripping characteristics. It can be combined with an appropriate ratio of lanthanide flame retardant, chlorinated paraffin and Al(OH)3 to obtain a flame retardant material with excellent flame retardancy and low cost.
4) CPE is non-toxic, does not contain heavy metals and PAHS, and it fully meets environmental protection requirements.
5) CPE has high filling performance and can produce products that meet various performance requirements. CPE has good processing properties, and Mooney viscosity (ML121 1+4) is available in a variety of grades from 50-100.
Chlorinated Polyethylene CPE CAS No. 63231-66-3 Application
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 CPE. Rubber type CPE 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, 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. 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, flame retardant, no explosion hazard.
Mainly used in: wire and cable (coal cable, UL and VDE and other standards specified in the wire), hydraulic hose, automotive hose, tape, rubber sheet, PVC profile pipe modification, magnetic materials, ABS modification and so on.
