Physical and Chemical Properties of Chlorinated Polyethylene (CPE)
Issue Time:2016-07-19

Chlorinated Polyethylene (CPE) is a kind of saturated polymer material. Its appearance is white powder. It’s non-toxic and odourless. It has excellent weatherability, ozone resistance, chemical resistance and ageing resistance. And it also has good oil resistance, flame retardancy and and coloring property. It has good toughness under 30 centigrade below zero. It has excellent compatibility with other polymers and high decomposition temperature.


Chlorinated Polyethylene (CPE) is a kind of polymer chlorinated from High Density Polyethylene (HDPE). As per their structure and different application, Chlorinated Polyethylene (CPE) is divided into two major types: Resin type and Elastomer type. Thermoplastic resin can be used solely and can also be blended with Polyvinyl Chloride (PVC), Polyethylene (PE), Polypropylene (PP), Polystyrene (PS), ABS resins and Polyurethane (PU). Chlorinated Polyethylene (CPE) is used as high-performance and quality specialty rubber. Chlorinated Polyethylene (CPE) can also be blended with EPR, IIR, NBR and CSM rubber.


CAS No.:63231-66-3

Density:1.22 g/mL at 25 oC



1. Chlorinated Polyethylene (CPE) is a kind of saturated rubber. It has excellent heat resistance, ageing resistance, ozone resistance, corrosion resistance and chemical resistance.


2. Chlorinated Polyethylene (CPE) contains Cl element, thus having excellent flame retardancy. It can be mixed with  Stibium based flame retardant, chlorinated paraffin wax and aluminum hydroxide in approximate proportion to produce a kind of flame retardant with good flame retardancy and low cost.


3. Chlorinated Polyethylene (CPE) is non-toxic and doesn’t contain heavy metal and PAHS. It’s a kind of environmental-friendly material.


4. Chlorinated Polyethylene (CPE) has good filling property, thus being used for manufacturing products with a variety of properties. Chlorinated Polyethylene (CPE) also has good processability.
