Impact Modifier
Impact modifiers are chemical additives designed to enhance the impact resistance of polymeric materials by leveraging the elastic toughness mechanism. They improve the toughness of rigid polymers, primarily used in PVC, PC, and PBT.
CPE 135-A
Chlorinated polyethylene CPE is a higher molecular elastomeric material that is chlorinated by HDPE. It is white powder and innocuous, it has excellent anti-flaming, weatherability, low temperature flexibility, and impact strength, etc. It can be blended with other plastics and rubber, mainly used as a PVC impact modifier.
