Lupranate® Monomeric MDI Product Line


Monomeric MDI (MMDI) refers to the 4,4’- and 2,4’-isomers of diphenylmethane diisocyanate. Pure 4,4’-MDI is a crystalline solid at room temperature. BASF sells frozen drums of 4,4’-MDI as Lupranate M and MS isocyanates. Above 45°C, pure 4,4’-MDI can be shipped and kept as a liquid for up to fifteen days. By blending 50% 2,4’-MDI into the 4,4’-MDI, the resulting mixture is a liquid at room temperature. Several variations in isomer distribution and stabilizer package are available in the MMDI product line.
