It is chlorinated by HDPE.Due to the molecule of CPE doesn't contain double bond,it has excellent weatherability,anti-flaming and wide application .It is mainly used as PVC inpact modifier.
It is white power and innocuous.Since hydrogen atoms are replaced by chlorine atoms,the crystallization of HDPE was destoryed and becomes soft and full of rubber property.Because of the presence of chlorine atoms,CPE turns into polar polymers and have the same polar groups as PVC.Under this situation ,it increses the compatibility of PVC.In addition,it can blend with PE,PS and rubber to improve its physical properties.
