Category: PVC Impact Modifier
ACR series Impact Modifier is a Weatherable Acrylic Impact Modifier used in rigid PVC products. It is a "core -shell" structure modifier, with cross-linked poly butyl acrylic as "core"and graft methyl methacrylate as "shell". It not only improves impact resistance performance of the product, but also increases the surface gloss of the product, and especially the weatherability of the product. It is especially suitable for outdoor products and broadly used in PVC profiles, sheets, boards, pipes, pipe fittings, etc.
Product Description:
Product Description:
Specialized additives designed to enhance impact resistance by absorbing and dispersing impact energy, preventing brittle fracture in polymers. Particularly critical for rigid or low-temperature applications.
Key Application Areas:
PVC Systems
Rigid PVC (profiles, pipes, sheets):
✓ Compensates for inherent brittleness
✓ Compatible with CPE/ACR/MBS modifiers
✓ Essential for weather-resistant applications (window frames, drainage systems)
Flexible PVC (cables, films):
✓ Works synergistically with plasticizers
✓ Improves low-temperature flexibility
Engineering Plastics
Polycarbonate (PC):
✓ Increases notch impact strength by 30-50%
✓ Critical for automotive components (headlamp housings, dashboards)
Polyamide (PA):
✓ Reduces low-temperature embrittlement
✓ Enables use in gears and sports equipment
PBT/PET Polyesters:
✓ Maintains impact strength at thin wall sections
✓ Ideal for electrical connectors (UL94 compliant)
Other Polymers
Polypropylene (PP):
✓ EPDM/POE-based toughening systems
✓ Enables bumper and appliance applications
ABS:
✓ Augments existing rubber phase
✓ Optimized for 3D printing filaments
