What is the Chlorinated polyethylene?
English name: Chlorinated Polyethylene
English Synonyms: Ethylene resinchlorinatedCl; Poly Ethylene, chlorinated; Chlorinated polyethylene, rolled
Structural formula: [CH2-CHCl-CH2-CH2] n
English abbreviation: CPE or CM
Chlorinated polyethylene (CPE) saturated polymer materials, the appearance of white powder, non-toxic and tasteless, with excellent weather resistance, ozone resistance, chemical resistance and anti-aging properties, has good oil resistance, flame resistance and coloring performance. Good toughness (flexibility at -30 ℃ still), and other polymer materials having good compatibility, high decomposition temperature, decomposition HCL, HCL catalyze the dechlorination of CPE.
Chlorinated polyethylene is made from high-density polyethylene (HDPE) substitution reaction of polymer materials by chlorination. Depending on the structure and purpose, chlorinated polyethylene resins can be divided into chlorinated polyethylene (CPE) and elastomeric chlorinated polyethylene (CM) two categories. In addition to the thermoplastic resin may be used alone, but also with polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS resin or the like polyurethane (PU) blend using. In the rubber industry, CPE can be used as a high-performance, high-quality special rubber, but also with ethylene-propylene rubber (EPR), butyl rubber (IIR), acrylonitrile-butadiene rubber (NBR), chlorosulfonated polyethylene (CSM), etc. Other rubber blends use.
CPE is a saturated rubber, has excellent heat oxygen aging, ozone aging, acid, chemical resistance.
2) CPE oil performance in general, where resistance to ASTM oil No. 1, No. ASTM 2 oil excellent performance, and NBR quite; excellent resistance to ASTM # 3 oil performance, better than the CR, and CSM quite.
3) CPE containing chlorine, with excellent flame retardant properties, and there is burning anti-drip properties. With antimony-based flame retardants, chlorinated paraffins proper proportion, Al (OH) 3 can be obtained with three excellent flame retardant properties, low-cost fire retardant material.
4) CPE non-toxic, non-heavy metal and PAHS, its full compliance with environmental requirements.
5) CPE filled with high performance, can be prepared in line with the various performance requirements. Processing performance of the CPE, a Mooney viscosity (ML121 1 + 4) at 50-100 There are many brands to choose between.
The late 1990s, the domestic demand for high-performance flame-retardant rubber growing, especially wire and cable industry, the development of auto parts manufacturing industry, led rubber type CPE consumer demand. Rubber type CPE is a comprehensive performance excellent heat aging oxygen ozone, flame resistance of specialty synthetic rubber.
Chlorinated Polyethylene Resin is a new type of synthetic material, with a series of excellent performance. It is PVC plastic excellent impact modifier, also comprehensive good performance synthetic rubber, has a very wide range of applications, has been widely used in cables, wires, hoses, adhesives, rubber products, sealing materials, fire-retardant conveyor belt , waterproofing membranes, films and various profiles and other products. CPE also with polypropylene, high and low pressure polyethylene, ABS and other blends to improve the flame retardant properties of these plastics, anti-aging properties and printing properties of the article. CPE can be seen as, polyvinyl chloride and 1.2 twelve random copolymer molecular chain saturated, polar chlorine atoms are randomly distributed, because it has excellent physical properties and chemical properties, widely used in mechanical, electrical , chemicals, building materials and mining industries. CPE heat resistance, ozone and weather resistance, aging better than most rubber, oil resistance than nitrile rubber (NBR), chloroprene rubber (CR), anti-aging better than chlorosulfonated vinyl chloride (CSM); acid, corrosion properties of alkali, salt and other, non-toxic, nonflammable, non-explosive.
Mainly used: wire and cable (coal with standards set forth in the wire and cable, UL and VDE, etc.), hydraulic hose, automotive hose, tape, rubber, PVC profile pipe modified magnetic material, ABS modified so on.
