CPE Impact Modifier (Chlorinated Polyethylene)
CAS Number: 68442-33-1
Chlorinated Polyethylene (CPE) Impact Modifier is a cost-effective elastomeric toughener for rigid PVC, particularly used in pipe, fittings, and profiles requiring good chemical and weather resistance. CPE-135A grade with 35% chlorine content is the standard modifier for rigid PVC, providing excellent low-temperature impact strength and oil resistance. It is widely used in both rigid and flexible PVC applications.
