Chlorinated polyethylene (CPE)
Chlorinated polyethylene is made from high-density polyethylene (HDPE) by chlorination. Due to the absence of double bonds in CPE molecules, it has good weather resistance, flame retardancy, and a wide range of applications. It is mainly used as an impact modifier for PVC.
The appearance is white powder, non-toxic. Due to the substitution of hydrogen atoms by chlorine atoms, the crystallinity of HDPE is disrupted, making it soft and rubber like. Due to the presence of chlorine atoms, CPE becomes a polar polymer with the same polar group as PVC, increasing the solubility of PVC. In addition, it can be blended with PE, PS, and rubber to improve physical properties.
