Toluene Diisocyanate (TDI) is a highly reactive aromatic diisocyanate widely used as a key intermediate in the production of polyurethane materials. It is a clear, colorless to pale-yellow liquid with excellent reactivity toward polyols, enabling the manufacture of flexible foams, elastomers, coatings, and adhesives. TDI is valued for its ability to deliver superior elasticity, resilience, and mechanical performance in finished polyurethane systems.
