Diisocyanates are one of the key reactive materials required to produce polyurethane. The most commonly used in foam production are toluene diisocyanate (TDI) and methylene diphenyl diisocyante (MDI). MDI is used in the manufacture of rigid foams whereas TDI is used in applications where flexible foam is used such as furniture and bedding.
