Product name: Chlorinated Polyethylene
Synonyms: CPE
Chemical family: PVC impact modifier
Introductions:
It is a type of irregular chlorinated high molecular polymer, which has excellent physical properties as PVC impact modifier. It is compatible with PVC easily, and has fine tensile strength, good shock-resistance and superior impact modification for rigid PVC materials. Under the correct processing conditions, it can form three-dimension net structure inside of rigid PVC products, and make the final products possess superior impact resistance at normal and low temperature.
