Brief Introduction
LS series Impact Modifier is the Weatherability 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 can only improve impact proof performance of the product, but also increase the surface gloss of the product, especially the weatherability of the product. It is especially suitable for outdoor products and broadly used in PVC profiles, sheets, sheets, pipes, pipe fitting etc.
