Methylene Diphenyl Diisocyanate (MDI) CAS:101-68-8 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 MDI contains monomeric MDI and products with higher […]

Toluene Diisocyanate (TDI)
Toluene Diisocyanate (TDI) CAS:584-84-9 TDI (Toluene Diisocyanate) is produced by a 3 step reaction. The first step is the nitration of toluene to obtain dinitrotoluene. Second step is the catalytic hydrogenation of Dinitrotoluene into toluene diamine TDA. Finally, the TDA react with phosgene to produce the TDI. TDI is commonly sold under 3 different ratio […]
