Toluene Diisocyanate

Product Description

General description:

Chemical Formula: C9H6N2O2

TDI is an important intermediate in the production of flexible polyurethane foam. TDI is obtained by the nitration of toluene. The hydrogenation of di-nitro toluene is then obtained to produce Toluene Diamine (TDA), which is, in turn, reacted with phosgene to form TDI. TDI is a clear, pale yellow liquid with a sharp, pungent odor. It is combustible only at high temperatures but burns to produce toxic gases (cyanides and nitrogen oxides). It is volatile, producing toxic concentrations at room temperature. The utmost care and safety measures have to be taken working with polyurethanes' production

These are also used to produce proinflammatory cytokines and the secretions of chemokines coming from bronchial epithelial cells.

Prakash Chemicals International Pvt. Ltd is amongst the top global suppliers of Toluene Diisocyanate and the leading exporter of toluene diisocyanate from India.

Application & Usage:

• Toluene Diisocyanate is a vital raw material for flexible polyurethane foam, for use in cushions, mattresses, garments, pads and gloves and packaging materials.
• TDI is used in polyurethane coatings for automotive refinishing, wood finishes, and high-performance anti-corrosion coatings.
• TDI is also used in PU based alkyd paints, wood varnish, floor treatment and wire and powder coating.
• TDI is also used as shock absorbers

Some niche areas of its applications:

Elastomers: this is a rubber-like polymer that has a stretching capability of multiple hundreds of percent. Simultaneously, polymers can also return to their original shape and size when the stress that has been applied while stretching is released. These have high melting and boiling points. They find their applications in lightning applications, for wheels in skates, for printing rollers, abrasion-resistant sheathings in mining steel, and many other paper industries.
