Diphenylmethane diisocyanate, or "MDI" for short, is a white to pale yellow molten solid, containing 4,4 '-diphenylmethane
diisocyanate, 2,4' -diphenylmethane diisocyanate, 2,2 '-diphenylmethane diisocyanate, and other isomers. Is the aromatics
downstream main products, widely used in polyurethane elastomers, synthetic fiber, artificial leather, solvent-free coatings and other polyurethane materials production field.
Especially in terms of heat insulation, sound insulation, abrasion resistance, oil resistance, elasticity, etc., it has the
advantages that other synthetic materials can't match. It is next to polyethylene. The sixth largest plastic after ethylene,
polypropylene, polystyrene and ABS (now surpassing ABS to become the fifth largest plastic), it has been widely used in national defense, aerospace, light industry, chemical industry, petroleum, textile, transportation, automobile, medical,etc. The field has become an indispensable emerging material for economic development and people's lives.
