Its use in polyurethane foams accounts for approximately 80 percent of the MDI consumed Appendix D1 2 Methylene diphenyl diisocyanate For the production of MDI, the condensation of aniline is done with formaldehyde to form methylenedianiline (MDA), which gets reacted with phosgene to form MDI. Methylene Diphenyl Diisocyanate C15H10N2O2 MDI is mainly used as industrial adhesive; bonding rubber to rayon and nylon; and woodchip binder for particle board. Typically, one tonne of polyurethane foam needs 0.616 tonne of MDI and 0.386 tonne of polyol, with 0.054 tonne pentane as a blowing agent. Methylene diphenyl diisocyanate, most often abbreviated as MDI, is an aromatic diisocyanate. tRlɤÂtÓ ÁRF ¡sçhC Methylenediphenyl diisocyanate (MDI) is defined as a type of aromatic isocyanate that has wide application base in large-scale commercial and consumer sector. Major producers include Bayer, Dow, Huntsman, Elastogran, Repsol, Shell Chemicals, and Tosoh.
