Chlorinated Polyethylene (CPE) Characteristics and Application | VIA Chemical

Chlorinated polyethylene (CPE) is a material gotten with the alternative of hydrogen atoms with chlorine atoms in high-density polyethylene (HDPE). CPE exists as a white powder. It is safe and unsavory.

 

The high-temperature thermal aging resistance of CPVC Compound produced from low-pressure polyethylene HDPE transcends to that of CPE made from high-pressure polyethylene. CPE is commonly produced in the thickness range of 0.93-- 0.96 g/cm3 with a typical molecular weight of 5-- 25 million and also the thaw index of 0.01-- 2.0 g/10 min. The level of chlorination has a considerable impact on the buildings of CPE. For instance, CPE is plastic when its chlorine material is much less than 15%, a polycarbonate elastomer when its chlorine material is 16%-- 24%, as well as a rubber-like elastomer when its chlorine web content is 25%-- 48%. It is a leather-like semi-elastic difficult polymer when its chlorine content is 49%-- 58% and comes to be a fragile resin when its chlorine material boosts to 73%. Crystallinity is gotten rid of from high-pressure polyethylene upon the introduction of about 27% chlorine material. Crystallinity is also removed when 30% chlorine material is presented right into high-crystallinity low-pressure polyethylene. CPE rubber elastomer ideally contains 30%-- 40% chlorine. CPE Rubber and Modifier consists of 25%-- 45% chlorine. Enhancing chlorine web content enhances the oil resistance, air leaks in the structure, as well as fire retardancy of the CPE item. By comparison, reducing chlorine material enhances the cool resistance, durability, and also compression flexing efficiency of the CPE item.

 

 

CPE can be divided into 2 classifications: resin-type CPE as well as elastomer-type CPE. CPE can be used alone or combined with PVC, polyethylene, polypropylene, polystyrene, ABS, and also polyurethane. CPE can be used as a high-performance, top notch rubber and also can be used with ethylene propylene rubber, butyl rubber, nitrile rubber, chlorosulfonated polyethylene. CPE changed with various other rubber materials is mostly used in the production of cords and wires, such as coal-mine cable, common usage cord, UL, as well as VDE, as well as in the production of hydraulic pipe, vehicle tube, tape, and plastic sheets. CPE with rubber materials are likewise utilized to change PVC account pipelines, magnetic products, and also ABS.

 

CPE enhancers are generally composed of carbon black and white carbon black. The filling system utilized in CPE manufacturing is primarily calcium carbonate, clay, or talc. Plasticizers for CPE are mostly DOA as well as DOS. Sodium stearate, magnesium oxide, barium stearate, and also lead sulfate are generally used as stabilizers in CPE production to take in the hydrogen chloride generated throughout vulcanization.

 

Offered that CPE is a saturated rubber, the typically made use of sulfur vulcanization system is inefficient in the vulcanization of CPE. Vulcanization systems for CPE are split into the thiourea, peroxy, thiadiazole, and triazoledimercaptoamine salt systems.
