MDI

MDI (methylenediphenyl diisocyanate or diphenylmethane diisocyanate) is a chemical compound from the group of isocyanates, which is widely used for polyurethane adhesives. MDI is usually in the form of a colorless to yellowish, flammable powder or in the form of flakes with a pungent odor. In addition to TDI (which is not used at RAMPF!), MDI is one of the world's most widely produced isocyanates.
