Properties
Chlorinated Polyethylene (CPE, CAS: 63231-66-3) serves as a key impact modifier for rigid PVC pipes. It shows excellent compatibility with PVC resin. After addition, it remarkably enhances low-temperature impact resistance and protects pipes from brittle cracking under impact and cold conditions. Benefiting from good weather resistance and anti-aging property, it is ideal for buried and outdoor products including water & drainage pipes, electrical conduits. During extrusion, it facilitates homogeneous plasticization, stabilizes production and delivers smooth pipe surface. CPE135A is a well-established mainstream modification solution for PVC pipes with balanced performance and cost.

CPE 135A for pvc pipe About

Chlorinated Polyethylene (CPE, typical grade CPE135A) is the most cost-effective impact modifier for rigid PVC pipes. Featuring excellent compatibility with PVC resin, CPE forms elastic dispersed phases inside the PVC matrix. It absorbs impact energy efficiently and overcomes the inherent brittleness of PVC, greatly improving low-temperature toughness and preventing pipe cracking during transportation, installation and cold service conditions.

With outstanding weather resistance and UV stability, CPE suits outdoor and buried PVC-U water supply pipes, drainage pipes and conduit pipes. It also promotes uniform plasticization and optimizes extrusion processability for smooth pipe surface. The recommended dosage is 812 phr. Widely adopted in the production of PVC-U pipes and fittings.
