In various sectors, methylene diphenyl diisocyanates (MDIs) are crucial raw materials used to create polyurethanes, urethane-prepolymers, and polyisocyanurate polymers. MDIs are employed in a broad variety of applications due to their reactivity and adaptability in interacting with a variety of cura Read More

An aromatic diisocyanate is methylene diphenyl diisocyanate (MDI). There are three common isomers: 2,2′-MDI, 2,4′-MDI, and 4,4′-MDI. These are distinguished by the locations of the isocyanate groups around the rings. The most common isomer, commonly known as 4,4′-diphenylmethane diisocyanate, is the Read More
