Chlorinated polyethylene (CPE) is a highly effective impact modifier widely used in the plastics industry. Compared to other impact modifiers such as acrylic-based AIM, MBS, and ABS, CPE stands out for its superior overall performance, excellent flexibility, and competitive cost, making it a preferred choice for enhancing polymer toughness.
PS-IM-CPE is specially formulated to improve the mechanical and thermal performance of PVC, PE, PP, and other polymers. When incorporated at appropriate levels, it significantly increases impact strength, enhances low-temperature toughness, improves weather resistance, and maintains compatibility with existing formulations. It can be used as a full replacement for acrylic-based AIM modifiers or blended with AIM in specific ratios, delivering optimal cost-effectiveness without requiring adjustments to processing parameters.
