Product Description

Product Description

MDI is a polyurethane material synthesized by isocyanate, polyol and its auxiliary agent. With its excellent properties, various varieties and broad uses, MDI is unique among many synthetic materials and has become one of the fastest developing materials today. As the main raw material for the synthesis of polyurethane, isocyanate, in the late 1930s, the German chemist O.Ayer and his colleagues first developed the synthesis method and processing technology of diisocyanate
