CPEbrief introduction

  Chlorinated polyethylene (CPE) is a random product of high-density polyethylene (HDPE) produced by chlorine substitution reaction. It can be regarded as ethylene, vinyl chloride, 1,2-vinyl chloride ternary polymer, with almost no double bond structure. With the change of chlorination conditions, chlorine content and polyethylene raw materials, products from rubber to hard plastic can be made.

  The chlorination mechanism of polyethylene is that chlorine generates free radicals with the aid of initiators. This chlorine atom attacks the C-H bond of the macromolecular chain (without affecting the C-C bond of the main chain) to generate free radicals. In the case of continuous supplement of chlorine, the free radical reaction chain transmits and transfers continuously by chain reaction to make the chlorination continuous. After meeting the chlorination requirements, the chlorination is stopped and terminated Reaction.
