Chlorinated Polyethylene(CPE) is a saturated polymer which has excellent weather resistance, ozone resistance, corrosion resistance, aging resistance, oil resistance, flame resistance and coloring properties, good low-temperature toughness, good compatibility with other polymer materials and higher thermal decomposition temperature.CPE has extensive application fields. The resin CPE is mainly used as modifier of PVC toughness and impact resistance and the flame resistant modifier; the Rubber CPE can be used alone or blended with other rubbers.
