High Chlorinated Polyethylene (HCPE) is a material obtained via the substitution of hydrogen atoms with chlorine atoms in high-density polyethylene (HDPE). CPE exists as a white powder. It is safe and also unappetizing.
The high-temperature thermal aging resistance of CPE made from low-pressure polyethylene HDPE is superior to that of CPE produced from high-pressure polyethylene. CPE is generally generated in the density array of 0.93-- 0.96 g/cm3 with an ordinary molecular weight of 5-- 25 million and also the melt index of 0.01-- 2.0 g/10 min. The degree of chlorination has a significant effect on the residential properties of CPE. For instance, CPE is plastic when its chlorine web content is much less than 15%, a polycarbonate elastomer when its chlorine material is 16%-- 24%, and 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 becomes a weak resin when its chlorine web content raises to 73%. Crystallinity is eliminated from high-pressure polyethylene upon the introduction of around 27% chlorine content. Crystallinity is likewise gotten rid of when 30% chlorine content is introduced into high-crystallinity low-pressure polyethylene. CPE rubber elastomer preferably includes 30%-- 40% chlorine. CPE rubber consists of 25%-- 45% chlorine. Enhancing chlorine web content enhances the oil resistance, air permeability, and flame retardancy of the CPE product. By comparison, reducing chlorine material boosts the cold resistance, durability, as well as compression bending performance of the CPE product.
CPE can be divided into 2 classifications: resin-type CPE and also elastomer-type CPE. CPE can be made use of alone or combined with PVC, polyethylene, polypropylene, polystyrene, ABS, and also even polyurethane. CPE can be made use of as a high-performance, top quality rubber and also can be applied with ethylene propylene rubber, butyl rubber, nitrile rubber, chlorosulfonated polyethylene. CPE changed with various other rubber products is mostly made use of in the manufacturing of wires as well as cords, such as coal-mine cable television, conventional usage cord, UL, and also VDE, and in the production of hydraulic hose, automobile hose, tape, and also plastic sheets. CPE with rubber products are additionally utilized to modify PVC profile pipelines, magnetic products, and ABS.
