CPE is the standardized acronym for thermoplastic chlorinated polyethylene elastomer, which is produced by chlorination of polyethylene. The chlorine content could be as high as 70% by weight, but the current grades have a chlorine content in the range of 25% up to 42%.
Chlorinated polyethylene elastomers (CPE) and resins have excellent physical and mechanical properties, such as resistance to oils, temperature, chemicals, and weather. They can also exhibit superior compression set resistance, flame retardancy, tensile strength and abrasion resistance.
CPE polymers can range from rigid thermoplastics to a flexible elastomer, making them highly versatile. These polymers are used in a variety of end-use applications such as wire and cable jacketing, roofing, automotive and industrial hose and tubing, molding and extrusion, and as a base polymer.
CPE blends well with many types of plastics such as Polyethylene, EVA, and PVC. Such blends can be formed into final products with adequate dimensional stability without the need of vulcanization. The excellent additive/filler acceptability characteristics of CPE can provide a benefit in blends where compound performance and economics are critical.
Our CPE offering portfolio can be categorized into three groups.
- Blends of CPE and Vinyl, which produce very robust compounds with exceptional oil resistance, physical and flame characteristics. If the environments contain oil, acids or alkalis, CPE jackets give more protection than PVC.
- TPO based CPE, with very low halogen content, superior low temperature properties and good flame characteristics.
- CPE systems suitable for radiation crosslinking. They are oil resistant, flame retardant, E-beam curable, CPE based compound suitable for wire & cable applications. Custom color matching is available upon request.
