Acrylic impact modifier: AIM series
AIM series impact modifiers are acrylic impact modifier with core/shell structure in which core being moderate cross linked structure is linked with shell by grafting copolymerization. It not only improves impact resistance performance of the product, but also increases the surface gloss, 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.
◎ Promote fusion
◎ Excellent weatherability
◎ Better impact strength
◎ Lower post-extrusion shrinkage
◎ Outstanding surface quality
