Toluene Diisocyanate

HS Code : 29291020 | CAS NO. : 584-84-9

General description:

Chemical Formula: C9H6N2O2

TDI is an important intermediate in the production of flexible polyurethane foam. TDI is obtained by 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. 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 is among the top suppliers of toluene diisocyanate and the leading exporter of toluene diisocyanate globally.

Application & Usage:

  • It is a vital raw material for flexible polyurethane foam, for use in cushions, mattresses, garments, pads and gloves and packaging materials.
  • It is used in polyurethane coatings for automotive refinishing, wood finishes, and high-performance anti-corrosion coatings.
  • Also used in PU based alkyd paints, wood varnish, floor treatment and wire and powder coating.
  • Also used as shock absorbers
  • High applications in the automobile industry
  • Bicycle wheel forks
  • Conveyor-rollers

Some niche areas of its applications:

  • Elastomers: this is a rubber-like polymer that has a stretching capability of multiple hundreds of per cent. 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.

Toxicity Effects of Toluene Diisocyanate:

  • These have toxic effects in respiratory tracts: they may induce asthma in humans.
  • Eye infection
  • Skin irritations and infections

FAQs


Can diisocyanates be used safely?

Diisocyanates can also be used safely for many years in varied applications. The safety data sheet which is provided by manufacturer mainly helps the users understand the hazards of diisocyanates. The recommended precaution and protective measurements should be taken while handling. During manufacturing you should take safety measures while handling toluene diisocyanates.

How to clean toluene diisocyanate?

While handling toluene diisocyanates you must follow the safety protocols to safeguard yourselves. During toluene diisocyanates manufacture it is must to follow the precautions. If it in direct contact with the eye or skin then there are many chances for you to get affected. You need to clean that by using chlorinated solvents.

What does toluene diisocyanate react with?

Toluene diisocyanates react with hydroxyl groups to form carbonate as a product it is also called urethane so that toluene diisocyanate suppliers export that to fertilizer industries. Because these urethane is formed by TDI and it is mainly used in objects that have different shapes and forms.

How to store toluene diisocyanate?

Toluene diisocyanate has to be stored between 20 degree Celsius and 25 degree Celsius. It has to be kept in a well-ventilated room. It has to be stored in an area without drain or sewer access. This has to be separated from the food and feedstuffs.

How is toluene diisocyanate used in making foams?

The reaction of toluene diisocyanate with polyol produces the foam. By the slab stock foaming process the majority of flexible foams are produced. Here the mixture of polyurethane raw materials is dispensed on to paper linings where it gradually expands into a large bun of foam. These are then cut into blocks.

Why is toluene diisocyanate important?

Toluene diisocyanate is an organic compound and is used in the production of polyurethanes. They are primarily for the flexible foam applications including bedding and furniture, carpet underlay and packaging applications. This is also utilized in the manufacture of coatings, sealants, and adhesives.
