Toluene diisocyanate (TDI) is a colorless or light yellow transparent liquid with a pungent odor, and it will slowly turn yellow under ultraviolet light. It can react with hydroxyl, water, amine and other compounds containing active hydrogen, and can self-polymerize under certain conditions to form urethane, urea, biuret, isocyanurate, etc. TDI chemical is an important raw material for polyurethane. TDI is often marketed as 80/20 and 65/35 mixtures of the 2,4 and 2,6 isomers respectively.
Toluene diisocyanate (TDI) is a highly reactive chemical used in the production of polyurethane foams, coatings, adhesives, and other materials.
