MBS Impact Modifier( MBS抗冲改性剂）
Methyl Methacrylate Butadiene Styrene polymer (MBS) impact modifiers, provide superb cold temperature impacts for extrusion, injection molding and calendering. Due to its composition, MBS impact modifier is used in non-weatherable applications. Both PVC clear and opaque versions of MBS impact modifiers are available. MBS抗冲改性剂是一种能提供优异的低温冲击强度的具有典型的核-壳结构的高分子聚合物，其核为丁苯橡胶共聚物, 因为双键的存在，MBS不能用于户外制品。MBS通用于PVC透明和非透明制品。
