Polyisocyanate (Methylene diphenyldiisocyanate (MDI), diphenylmethane diisocyanate) is an aromatic diisocyanate.
It is commonly known as three isomers: 4,4-MDI, the most widely used isomer, also known as pure MDI and 2,2-MDI, 2,4-MDI.
Polyisocyanate is a dark brown liquid mixture of 4, 4-diphenylmethane diisocyanate (MDI) with isomers and homologues.
In the production of polyurethane foam (PPU), MDI is more often referred to as "component B" of a system that forms polyurethane by reacting with "component A".
