Product Description

  Toluen e Diisocynate (TDI) is an organic compound with the formula CH₃C₆H₃(NCO)₂. Two of the six possible isomers are commercially important: 2,4-TDI (CAS: 584-84- 9) and 2,6-TDI (CAS: 91-08- 7). 2,4-TDI is produced in the pure state, but TDI is often marketed as 80/20 and 65/35 mixtures of the 2,4 and 2,6 isomers respectively.

    It is produced on a large scale, accounting for 34.1% of the global isocyanate market in 2000, second only to MDI. Approximately 1.4 billion kilograms were produced in 2000. All isomers of TDI are colorless, although commercial samples can appear yellow.

    2,4-TDI is prepared in three steps from toluen e via dinitrotoluen e and 2,4-diaminotoluen e (TDA). Finally, the TDA is subjected to phosgenation, i.e., treatment with phosgene to form TDI. This final step produces HCl as a byproduct and is a major source of industrial hydrochloric a cid.
 
    Distillation of the raw TDI mixture produces an 80:20 mixture of 2,4-TDI and 2,6-TDI, known as TDI (80/20). Differentiation or separation of the TDI (80/20) can be used to produce pure 2,4-TDI and a 65:35 mixture of 2,4-TDI and 2,6-TDI, known as TDI (65/35).

    TDI (toluen e 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.

    It is mainly used for producing flexible polyurethane foam and polyurethane elastomers, coatings, adhesives and so on.
