TDI (toluene diisocyanate) is one of the commonly used polyisocyanates, and polyisocyanates are polyurethane (PU) materials and important basic raw materials.
TDI commonly used in polyurethane industry is a mixture of 2,4-TDI and 2,6-TDI isomers, including three commonly used brands: TDI-80/20, TDI-100 and TDI-65/35.
The preceding figures indicate the content of 2,4-TDI in the composition.
For example, 80 in TDI-80/20 indicates that its composition is 80% 2,4-TDI and 20% 2,6-TDI; 100 in TDI-100 basically represents 2,4-TDI (about 98%) and 2,6-TDI has few isomers.
TDI is mainly used for producing flexible polyurethane foam and polyurethane elastomers, coatings, adhesives and so on
