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.

Lupranate® Monomeric MDI Product Line Case Studies
The "Pengins Project", is the exceptionally challenging process of continuously extracting crude oil deposits from the English North Sea territory. ELASTOGRAN took on the challenge to develop made-to-measure, off-shore pipe insulation for the Penguins pipelines, through focused know-how and the benefit of vast experience.
Using the Sandwich Plate System, BASF is working to revolutionize shipbuilding, by replacing the conventional steel construction, with just two steel plates filled with liquid polyurethane, reducing corrosion and making them more resistant to mechanical stress.
