Chlorinated Polyethylene (CPE) Characteristics and Application | VIA Chemical

Chlorinated polyethylene (CPE) is a material obtained via the alternative of hydrogen atoms with chlorine atoms in high-density polyethylene (HDPE). CPE exists as a white powder. It is non-toxic as well as tasteless.

The high-temperature thermal aging resistance of CPE made from low-pressure polyethylene HDPE transcends to that of CPE produced from high-pressure polyethylene. CPE is generally generated in the density variety of 0.93-- 0.96 g/cm3 with a typical molecular weight of 5-- 25 million and the melt index of 0.01-- 2.0 g/10 min. The degree of chlorination has a considerable effect on the homes of CPE Rubber and Modifier . As an example, CPE is plastic when its chlorine material is less than 15%, a polycarbonate elastomer when its chlorine material is 16%-- 24%, as well as a rubber-like elastomer when its chlorine content is 25%-- 48%. It is a leather-like semi-elastic difficult polymer when its chlorine content is 49%-- 58% as well as comes to be a weak material when its chlorine material enhances to 73%. Crystallinity is gotten rid of from high-pressure polyethylene upon the introduction of approximately 27% chlorine content. Crystallinity is also gotten rid of when 30% chlorine web content is presented right into high-crystallinity low-pressure polyethylene. CPE rubber elastomer ideally contains 30%-- 40% chlorine. CPE rubber consists of 25%-- 45% chlorine. Enhancing chlorine content improves the oil resistance, air permeability, and fire retardancy of the CPE product. By contrast, decreasing chlorine web content improves the cool resistance, resilience, and also compression bending performance of the CPE item.

CPE can be divided right into two categories: resin-type CPE and also elastomer-type CPE. CPE can be utilized alone or mixed with PVC, polyethylene, polypropylene, polystyrene, ABS, and even polyurethane. CPE can be utilized as a high-performance, high-grade rubber and can be applied with ethylene propylene rubber, butyl rubber, nitrile rubber, chlorosulfonated polyethylene. CPE modified with other rubber materials is primarily utilized in the production of cords and also cables, such as coal-mine cord, standard usage cord, UL, and also VDE, as well as in the production of hydraulic pipe, automobile pipe, tape, as well as plastic sheets. CPE with rubber products are also used to change PVC profile pipes, magnetic materials, and also ABS.
