Toluene Diisocyanate (TDI) – High Reactivity Isocyanate for Polyurethane Production
Toluene Diisocyanate (TDI) is a highly reactive aromatic isocyanate widely used in the production of polyurethane foams, coatings, adhesives, and elastomers. As a key raw material in the polyurethane industry, TDI 80/20 (a mixture of 2,4-TDI and 2,6-TDI isomers) delivers excellent reactivity, flexibility, and processing performance.
Toluene Diisocyanate TDI is particularly suitable for flexible foam applications such as furniture cushions, mattresses, automotive seating, and insulation materials. Its fast reaction profile and compatibility with polyols make it an essential component in industrial formulations.
