Toluene Diisocyanate (TDI)

TDI (Toluene Diisocyanate) is a highly reactive compound used in the manufacturing of flexible polyurethane foam. It serves as a critical component alongside polyols, reacting to form the polyurethane polymer matrix that gives the foam its flexibility and resilience. TDI is typically a clear to pale yellow liquid with a pungent odor, known for its high reactivity, versatility in formulation, and stability when handled properly.
