MBS(Methyl methacrylate-Butadiene-Styrene) resin is methacrylic acid ester (M), butadiene (B) and styrene (S) terpolymer, it tool has type 核- housing/shell structure.

due to its solvent degree parameters and PVC versus 近, 故两者 hot force versus property good, performance is PVC in room temperature or low temperature lower tool has very high impact resistant strong/high degree. and due to it and PVC折 light versus 近, 故当两者 blending melt rear, easy to 均一 折射 rate, therefore use MBS做PVC impact modifier effect/influence PVC transparent property, therefore MBS is PVC made transparent products most material. 另一方面, due to its and PVC versus property good, in room temperature or low temperature lower tool has very high impact resistant property, suitable for non transparent property various products.

MBS resin production process is butadiene and styrene in water and emulsification agent in emulsification, in agent function lower polymerization, production 丁苯胶乳(SBR胶乳), again add styrene and methacrylic acid ester emulsion grafting polymerization, to MBS resin grafting 胶乳(MBS resin 胶乳), most rear 经 凝 poly, water and drying rear to MBS resin formed product.

in MBS resin production process process in, has 3 large key/critical technology.

its is SBR胶乳 combined formed technology, is SBR胶乳 粒径不但决定 MBS resin, pvc alloy impact resistant property can, meanwhile also it light property can;

its is MBS resin combined formed technology, is 核-- housing/shell ratio, grafting rate and grafting process mono add material and other for MBS resin 胶乳 凝 poly and rear 处理, MBS resin powder material pellets and MBS resin and PVC versus property and optical property can and other has non significantly effect/influence;

its is MBS resin 胶乳 凝 poly technology, poly water high low 直接决定 most product degree distribution, pellets property, flow property and table/sheet density and MBS resin in PVC in dispersion property and versus property and other indicators.
