Toluene Diisocyanate(TDI)

CAS: 584-84-9

TDI(toluene diisocyanate) is a commonly used polyisocyanate, which is a polyurethane (PU)material and an important basic raw material. TDI is a mixture of two isomers, 2,4-TDI and2,6-TDI, commonly used in the polyurethane industry, including three common grades :TDI-80/20,TDI-100 and TDI-65/35. The preceding numbers indicate the amount of 2, 4-TDI in the composition.
For example, 80 in TDI-80/20 means 2, 4-TDI (80%) and 2, 6-TDI (20%). The 100 in TDI-100 is basically 2, 4-TDI(about 98%), with very few isomers of 2, 6-TDI. Mainly used in the production of soft polyurethane foam and polyurethane elastomers, coatings, adhesives and so on.
