CPE

Introduction:
It is chloridized by HDPE. Due to the molecule of CPE does not contain double bond, it has excellent weatherability, anti-flaming and wide application. It is mainly used as PVC impact modifier.

Product performance:
It is white powder and innocuous. Since hydrogen atoms are replaced by chlorine atoms, the crystallization of HDPE was destroyed and becomes soft and full of rubber property. Because of the presence of chlorine atom, CPE turns into polar polymers and has the same polar groups as PVC. Under this situation, it increases the compatibility of PVC. In addition, it can blend with PE, PS and rubber to improve its physical properties.

Application: It is applicable for PVC profile, non-conventional PVC, PVC pipe, PVC pipe fittings. It is also used for the soft products together with PVC, EVA or paracril.
