Toluene Diisocyanate (TDI)

Description

What is Toluene Diisocyanate (TDI)?

Toluene Diisocyanate (TDI) is a highly versatile organic compound widely used in the production of polyurethane products, particularly flexible foams. With the chemical formula CH₃C₆H₃(NCO)₂, TDI is an aromatic diisocyanate available mainly in two commercially important isomers: 2,4-TDI (CAS: 584-84-9) and 2,6-TDI (CAS: 91-08-7).
Due to its excellent reactivity and performance, TDI is a preferred raw material for the furniture, bedding, automotive, footwear, and coatings industries. Chemex Chemicals is one of the leading importers and trusted suppliers of Toluene Diisocyanate (TDI) in India, providing high-quality material at competitive prices.
