Acrylic Impact Modifier
Acrylic Impact Modifiers based on core-shell architecture provide outstanding toughening performance for rigid PVC without sacrificing weatherability or clarity. The rubbery acrylic core absorbs impact energy while the hard shell ensures compatibility and dispersion within the PVC matrix. They are the preferred choice for outdoor applications where UV resistance is a priority.
