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 […]
