MBS抗沖改性劑是一種能提供優(yōu)異的低溫沖擊強(qiáng)度的具有典型的核-殼結(jié)構(gòu)的高分子聚合物,其核為丁苯橡膠共聚物, 因?yàn)殡p鍵的存在,MBS不能用于戶外制品。MBS通用于PVC透明和非透明制品。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.
