Chlorinated Polyethylene Definition:

Chlorinated polyethylene (CPE) is a saturated polymer material, white powder, non-toxic and odorless in appearance, has excellent weather resistance, ozone resistance, chemical resistance and aging resistance, and has excellent 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 reaction of CPE.

Chlorinated polyethylene can be divided into resin-type chlorinated polyethylene (CPE) and elastomer-type chlorinated polyethylene (CM) according to its structure and use.

In addition to being used alone, thermoplastics can also be mixed with resins such as polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS and polyurethane (PU).

In the rubber industry, CPE can be used as a high-performance, high-quality specialty rubber and can also be combined with ethylene propylene rubber (EPR), butyl rubber (IIR), nitrile rubber (NBR) and chlorosulfonated polyethylene (CSM). ) and other rubbers are mixed.

Product features:

  1. Chlorinated polyethylene is a saturated rubber with excellent heat and oxygen aging resistance, ozone aging resistance, acid alkali resistance and chemical resistance.
  2. CPE has general oil resistance and has excellent resistance to ASTM No.1 oil and ASTM No.2 oil equivalent to NBR among them, and resistance to ASTM No.3 oil is CR, which is the same as CSM.
  3. CPE contains chlorine element, so it has excellent flame retardancy and combustion and dripping characteristics. By mixing antimony flame retardant, chlorinated paraffin, and Al(OH)3 in an appropriate ratio, a flame retardant material with excellent flame retardancy and low cost can be obtained.
  4. Chlorinated polyethylene is non-toxic, does not contain heavy metals and PAHs, and fully meets the requirements of environmental protection.
  5. CPE has high filling performance and can be manufactured to meet various performance requirements. The processing performance of CPE is good and Mooney viscosity is available in various grades between 50-100.


  1. Used for cable sheathing Neoprene rubber began to be used for rubber sheathing, followed by chlorosulfonated polyethylene in the 1950s, and CPE was not introduced until the end of the 1960s. These rubber materials can be used to meet the design and performance requirements of cables.
  2. Used in heat-resistant conveyor belts CPE is used to manufacture polarity and expansion-resistant materials such as heat-resistant conveyor belts such as tar and asphalt.
  3. For industrial hoses, the ozone resistance, weather resistance and flame retardancy of CPE are inherent to polymers, so they are far superior to rubber compounds that are commonly used with compounding agents extracted to improve these properties. Excellent extrusion performance, suitable for internal and external adhesives on hoses.
  4. Chlorinated Polyethylene can also be used as the outer rubber layer of rubber rollers used in the steel or textile industries to press rollers or transport rubber rollers in copiers.
  5. Used together with styrene butadiene rubber, EPDM rubber, etc., it has excellent extrusion performance and weather resistance, low price, and can be used as extrusion products such as window moldings for automobile and construction industries.
  6. When combined with other rubbers, a closed-cell sponge rubber with a smooth surface and good aging resistance can be obtained. CPE still has sufficient physical and mechanical properties while adding a large amount of filler, and can be applied without vulcanization. Representative products include waterproofing membranes for roofs and magnetic rubber.
  7. CPE elastomer has achieved excellent application effect in soft PVC products such as waterproof coils and films, as well as insulated wire and cable sheathing materials.
  8. Chlorinated Polyethylene Modified PE Application The addition of CPE to polyethylene can improve printability, flame retardancy and flexibility. If CPE and white oil are added to the formulation of PE hose for mining, the flame retardancy is improved, there is no melt flow during combustion, and the density of the CPE-modified PE foam plastic foam increases.
  9. Application of Chlorinated Polyethylene as a Compatibilizer CPE is a compatibilizer for binary blending systems used to modify blending with ABS, PS, PP, PE, PVC, and rubber. For example, it can significantly improve toughness, impact strength and promote plasticization in PVC/PE blend systems. Blend’s injection molded products can be used as machine parts, and 1/3 of the products are used for compounding and thin film coating.
