Both 2,4-toluene diisocyanate (TDI) and 4,4-methylene diphenyl diisocyanate (MDI) can cause occupational asthma. The most commonly used isocyanate in urethane adhesives is MDI. The global market for diisocyanates in the year 2000 was 4.4 million tonnes, of which 61.3% was methylene diphenyl diisocyanate (MDI), 34.1% was toluene diisocyanate (TDI), 3.4% was the total for hexamethylene diisocyanate (HDI) and isophorone diisocyanate … MDI should be not be heated or sprayed except with strict engineering controls and personal protective equipment. MDI is used primarily in the production of rigid polyurethane foams used for insulation for your home or refrigerator, and many other uses. Methylene Diphenyl Diisocyanate C15H10N2O2 MDI is mainly used as industrial adhesive; bonding rubber to rayon and nylon; and woodchip binder for particle board. Since it polymerizes in the presence of water, its ecological risks are low. The group at the 4-position is approximately four times more reactive than the group at the 2-position.[1]. Skeletal formula of 4,4'-methylene diphenyl diisocyanate (4,4'-MDI, Pure MDI). MDI is reactive with polyols in the production of polyurethane. MDI is reacted with a polyol in the manufacture of polyurethane. It exists in three isomers, 2,2'-MDI, 2,4'-MDI, and 4,4'-MDI.
