Acrylic Impact Modifier

Product Description

Product Overview

ACRYLIC impact modifier is a polymer additive based on acrylic core-shell structure, designed specifically to enhance the impact toughness of PVC, especially hard PVC. Its unique core-shell microstructure (hard core+soft shell) can form an elastic dispersed phase in the PVC matrix, effectively absorbing impact energy, significantly improving the material's impact resistance, while maintaining excellent weather resistance and processing stability.

Core Features:

Ultra high impact resistance

Excellent weather resistance

Transparency optional
Some models have a refractive index that matches PVC and can be used for high transparency products such as medical packaging and transparent sheets.

Processing compatibility

Rigid toughness balance
While improving toughness, it has little impact on the rigidity (bending modulus) of PVC, making it suitable for structural components.

Applications

Summary
ACRYLIC impact modifier is the preferred choice for high-end rigid PVC products, especially suitable for applications that require weather resistance, high impact resistance, and low temperature toughness (such as door and window profiles, automotive components). Although the cost is higher than CPE/MBS, its comprehensive performance advantages can significantly extend product life and reduce long-term maintenance costs. For transparent or extremely low-cost requirements, MBS or CPE can be chosen as alternative solutions at discretion.
