Methylene Diphenyl Diisocyanate (MDI)
Methylene Diphenyl Diisocyanate is produced by a 4 steps reaction based on benzene as feedstock.
There are 3 isomers of MDI : 2,2-MDI, 2,4-MDI, and 4,4-MDI. The 4,4 isomer is known as pure or monomeric MDI (mMDI).The Polymeric MDI so called Crude MI contains monomeric MDI and products with higher MW (pMDI).
MDI is used to produce foam for Insulation, PU elastomer, shoe soles, systems houses, synthetic leather, cold stores, sport floor, foundry, mining, …
MDI is the least hazardous of the commonly available isocyanates because of its low vapour pression but it is not benign.
