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.
