CHLORINATED POLYETHYLENE(CPE135A)
Introduction :
It is chloridized by HDPE. Because the molecule of CPE doesn't contain double bond, it has excellent weatherability, anti-flaming property 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 crytallization 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 have 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.
