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 […]

Polyether Polyols Polyether polyols Chemical Structure Composition Polyether Polyols are made by reacting organic oxide and glycol. Main organic oxide utilized are EO, PO, BO, Epichlorohydrin. Main glycols utilized are EG, PG, Water, Glycerine, Sorbitol, Sucrose, THME. The decision to use a polyether rather than polyester will depend on the final properties of the material […]
