MDA-100 为含有99.0%以上的4,4’-二氨基二苯基甲烷和少量的2,4’-二氨基二苯基甲烷的芳香二胺混合物,
其主要成分的结构式为:
分子量为198.26;
室温下呈白色或浅黄色固体状态。它是一种重要的化工中间体,除主要用于生产MDI、HMDI 外,还大量用于制备聚酰亚胺(Pl) 绝 缘漆、聚脂亚胺 (PEI) 绝缘漆、双马树脂等电绝缘材料,还可用于环氧树脂的固化剂,聚氨酯弹性体的扩链剂。用MDA合成的上述各种 产品,具有优良的力学性能、绝缘性能、耐高温性能、耐辐射性能和耐磨耗性能。
MDA-100 contains more than 99.0%of 4,4'-methylenedianiline and a small amount of 2,4'-methylenedianiline.It is an aromatic diamine mixture.The molecular weight is 198.26 and it is in white or light yellow solid state at room temperature.
MDA-100 as an important chemical intermediate,it can be widely used in MDI, HMDI,PI,PEI,epoxy resin hardener,performance thermoplastic,chain extender of PU elastomer etc.These products synthesized with it have excellent properties of mechan- ics,electrical-insulation,heat-resisting,radiation-resisting and abrasion-resisting.
