Impact Modifier Chlorinated Polyethylene135A
Product introductionChlorinated polyethylene, is made from high density polyethylene (HDPE) by chlorination, because CPE molecules do not contain double bonds, has good weather resistance, at the same time with fire resistance, wide application range and other advantages, mainly used as PVC impact modifier.Product performanceAppearance is white powder, non-toxic, due to the hydrogen atoms are replaced by chlorine atoms, the damage to the crystallization of HDPE, make its have the rubber becomes soft and nature, because of the presence of chlorine atom, make CPE polar polymer and has the same polar groups with PVC, increased the intermiscibility of PVC, in addition to PE, PS and rubber blending to improve physical properties.
