Chlorinated polyethylene(CPE, CPE 135A; CPE 135B and the various derivatives) is an inexpensive variation of polyethylene having a chlorine content from 34 to 44%. It is used in blends with polyvinyl chloride (PVC) because the soft, rubbery chlorinated polyethylene is embedded in the PVC matrix, thereby increasing the impact resistance. In addition, it also increases the weather resistance. Furthermore, it is used for softening PVC foils, without risking plasticizer migration. Chlorinated polyethylene can be crosslinked peroxidically to form an elastomer which is used in cable and rubber industry. When chlorinated polyethylene is added to other polyolefins, it reduces the flammability. Application CPE-135A is recommended to produce all kinds of opaque PVC productsas PVC profiles, PVC fence, PVC pipe products, etc. Product group characteristics Performance Indicator Appearance Whitepowder Volatile Content(%) 0.40 Heat of fusion(J/g) 2.0 Chlorine Content(%) 352 Sieve residue(0.9mm aperture) 2.0 Colored Particles (pieces/100g ) 20 Tensile Strength(Mpa) 6.0 Shore A hardness(A) 65 Tg(C) 1.1-1.2 Specific gravity 0.40-0.60 Bulk density(g/cm3) 5.0 CaCo3 content(%) 5.0 Reference formulation Recommended using dosage:8.0-12.0kg per 100kg PVC resin.
