About Toluene Diisocyanate TDI
Toluene Diisocyanate (TDI) is an aromatic diisocyanate produced through the phosgenation of toluene diamine. It exists primarily as a mixture of 2,4 and 2,6 isomers, with the 80/20 ratio being the most commercially significant form for the production of flexible polyurethane foams.
In the Indian market, TDI is a critical raw material for the rapidly expanding mattress and automotive seating sectors. It is also extensively used in the formulation of polyurethane-based paints, varnishes, and adhesives that require high chemical resistance and durability in tropical climates.
Procurement of TDI in India requires strict adherence to safety protocols due to its toxicity and reactivity. Buyers should source from reputable suppliers who provide certified material with proper moisture-free packaging, as TDI reacts violently with water and moisture-laden air.
