Applicationofchlorinatedpolyethylenerubberinthemarket

At present, most of the chlorinated polyethylene applications in the chemical market are rubber-type chlorinated polyethylene, which should be used in a wide range of applications, such as: wire and cable (cables for coal mines, wires specified in UL and VDE standards), hydraulic Hose, automotive hose, tape, rubber sheet, PVC pipe modification, magnetic material, ABS modification, etc.

   Chlorinated polyethylene (CPE) is a saturated polymer material. The appearance is white powder, non-toxic and tasteless. It has excellent weather resistance, ozone resistance, chemical resistance and aging resistance. It has good oil resistance, flame resistance and coloring. performance. Good toughness (still flexible 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 made from high-density polyethylene (HDPE) through a chlorination substitution reaction. According to different structures and applications, chlorinated polyethylene can be divided into two types: resin-type chlorinated polyethylene (CPE) and elastomer-type chlorinated polyethylene (CM). In addition to being used alone, thermoplastic resins can also be blended with resins such as 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 used with ethylene-propylene rubber (EPR), butyl rubber (IIR), nitrile rubber (NBR), chlorosulfonated polyethylene (CSM), etc. Other rubber blends.

Chlorinated polyvinyl chloride

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

2) CPE has excellent oil resistance, among which ASTM 1 oil and ASTM 2 oil have excellent performance, which is equivalent to NBR; ASTM 3 oil has excellent performance, which is superior to CR and comparable to CSM.

3) CPE contains chlorine element, has excellent flame retardancy, and has anti-flammability properties. It can be combined with antimony flame retardant, chlorinated paraffin, and Al (OH) 3 in appropriate proportions 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 fully meets environmental protection requirements.

5) CPE has high filling performance and can be made into products that meet various performance requirements. CPE has good processing performance. Mooney viscosity (ML121 1 + 4) is available in various grades between 50-100.
