MDI is by isocyanate and polyol and cooperate with additive synthesis of polyurethane materials, with its superior performance, in a wide range of variety, wide use, is unique among many synthetic materials, now became one of the fastest growing materials as the main raw material of synthesis of polyurethane, isocyanate, in the 1930 s, by a German chemist onychoteuthis ayer and his colleagues developed diisocyanate synthesis and processing technology for the first time

MDI PM-200 is a diisocyanate-diphenylmethane(MDI)-based composition containing some higher functionality isocyanates. The functionality is about 2.6-2.7. It is a brown liquid at ambient temperatures.
MDI PM-200 can be widely used in the production of rigid PU foam heat-insulating materials; also used in isocyanurate foam, paints, adhesives, structural foam, cellular integral skin foam, automotive bumper and interior parts, high-resilience foam and synthetic wood, etc. Due to its unique composition structure, PM-200 can provide better flowability. It is, therefore, particularly suitable for the production which require strict flowability of systems.
Pure MDI: white to yellowish crystal at room temperature, storage temperature below 5 degrees, , packing generally 250 kg iron drum nitrogen filled packaging (tank car nitrogen filled ) Polymerized MDI: colorless brown liquid, stored at room temperature, shelf life of two years, the packaging is generally 250 kg iron drum nitrogen-filled packaging.
