23 January 2023
What is Toluene Diisocyanate?
Toluene Diisocyanate (TDI) is an organic compound composed of toluene and isocyanate groups. It is a colorless to yellow liquid that is highly reactive and flammable. TDI manufactured as well as supplied by one of the top-ranked Toluene Diisocyanate suppliers in Kazakhstan, is used in the production of polyurethane (PU) foam, which is used in a variety of applications such as insulation, upholstery, and automotive parts.
TDI is produced by the reaction of toluene and phosgene. The reaction produces a mixture of isomers, including 2,4-TDI and 2,6-TDI, which are used in different applications. 2,4-TDI is mostly used for the production of flexible polyurethane foam, while 2,6-TDI is mostly used for the production of rigid polyurethane foam.
TDI is also used to produce other polyurethane-based products such as coatings, adhesives, and sealants. However, TDI can be dangerous to handle and use due to its highly reactive nature, and it can cause skin and respiratory irritation. Therefore, proper protective equipment and safety measures must be taken when handling TDI.
