Chlorinated polyethylene rubber in the market application

At present, the chlorinated polyethylene in the chemical market is mainly rubber-type chlorinated polyethylene, which should have a wide range of applications, such as: wire and cable (coal mine cable, UL and VDE and other standards specified in the wire), hydraulic hose, automotive hose, tape, rubber plate, PVC pipe modification, magnetic materials, ABS modification and so on.

Chlorinated polyethylene (CPE) is a saturated polymer material, the appearance of white powder, non-toxic and tasteless, with excellent weather resistance, ozone resistance, chemical resistance and aging resistance, with good oil resistance, flame retardant and coloring properties. Good toughness (still flexible at -30℃), has good compatibility with other polymer materials, high decomposition temperature, decomposition of HCl, HCL can catalyze the dechlorination reaction of CPE.

Chlorinated polyethylene is a polymer material prepared from high density polyethylene (HDPE) by chlorination substitution reaction. According to the different structure and use, chlorinated polyethylene can be divided into resin chlorinated polyethylene (CPE) and elastic type chlorinated polyethylene (CM) two categories. In addition to being used alone, thermoplastic resins can also be blended with polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS and even polyurethane (PU). In the rubber industry, CPE can be used as a high-performance, high-quality special rubber, and can also be blended with ethylene propylene rubber (EPR), butyl rubber (IIR), nitrile butadiene rubber (NBR), chlorosulfonated polyethylene (CSM) and other rubbers.

Chlorinated polyvinyl chloride

1) CPE is a kind of saturated rubber, with excellent heat resistance to oxygen aging, ozone aging, acid and alkali resistance, chemical properties.

2) CPE has excellent oil resistance, including excellent resistance to ASTM 1 oil and ASTM 2 oil, which is comparable to NBR; Excellent resistance to ASTM 3 oil, better than CR, and comparable to CSM.

3) CPE contains chlorine, has excellent flame retardant performance, and has combustion anti-drip characteristics. The flame retardant material with good flame retardant performance and low cost can be obtained by the appropriate proportion of antimony flame retardant, chlorinated paraffin and Al(OH)3.

4) CPE is non-toxic, does not contain heavy metals and PAHS, and fully meets environmental requirements.

5) CPE has high filling performance and can be prepared to meet a variety of different performance requirements. CPE has good processing properties and Mooney viscosity (ML121 1+4) is available in a variety of grades between 50-100.
