CPE 135A
CPE 135A is mainly used as an impact modifier for rigid PVC products. Under proper processing conditions, the addition of CPE 135A leads to the formation of a three-dimensional network structure within the rigid PVC products. As a result, rigid PVC products can maintain good impact resistance even in low-temperature environments.
Product Introduction
CPE135A is a high-performance Chlorinated Polyethylene (CPE) widely used as an impact modifier for rigid PVC products. It is produced through the chlorination of High-Density Polyethylene (HDPE), offering excellent toughness, weather resistance, and processing performance.
CPE135A is one of the most commonly used PVC additives in the plastics industry and is especially suitable for PVC pipes, profiles, boards, sheets, and cable materials.
With excellent compatibility with PVC resin, CPE135A can significantly improve the impact strength and low-temperature resistance of finished products while maintaining good processing stability.
Main Features
- Excellent impact resistance
