CHLORINATED POLYETHYLENE CPE135A

Chlorinated Polyethylene, often referred to as CPE, is a polymer derived from High-Density Polyethylene (HDPE) through partial chlorination. The introduction of chlorine atoms grants CPE a degree of softness and rubber-like properties. Moreover, it transforms CPE into a polar polymer with polar groups akin to PVC, bolstering compatibility with PVC.

CPE functions as an accelerator in the PVC plasticization process. As the CPE content increases, the plasticization time is reduced, while the plasticization torque and equilibrium torque experience an uptick. Simultaneously, the viscosity of the plasticized melt rises. With an increasing degree of chlorination, the original crystalline HDPE gradually transitions into an amorphous elastomer, further enhancing CPE's adaptability for PVC modification.
