Product Description:LS 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.
