BX IM 156 Impact Modifier


MBS series are products with a “core-shell” structure and excellent toughness performance. The products of this series are the copolymer of methyl methacrylate(M), butadiene(B), styrene(S) and the fourth functional monomer. These are synthesized resins specially developed to improve the impact strength and processing performance of PVC products. These are especially suitable to make indoor products, such as PVC films, sheets, pipes, pipe fittings, WPC, bottles, and granular materials.
BX IM 156 provides PVC products with superior impact resistance at normal to low temperatures. Replace Dow BTA 707/717, KANEKA B622, ARKEMA C140, LG CHEM MB-872.
