When you work by Toluene diisocyanate, TDI

Exposure to toluene diisocyanate, TDI and related compounds is well known to result in skin and lung sensitization among workers and has been documented to cause asthma, lung damage, and in severe cases, fatal reactions.

Exposure of humans to toluene diisocyanate causes tissue irritation, especially to the mucous membranes, and can produce severe respiratory problems. These isomers are reasonably anticipated to be human carcinogens. TDI may pose a risk to human health.

Toluene diisocyanate, TDI may be found in certain products available to consumers. Manufactory should follow any safety warnings and directions on product labels and dispose of products responsibly.

If diisocyanate exposures were to occur well above 20 ppb, evidence indicates that respiratory sensitization and asthma represent the greatest potential health concerns. Nevertheless, TDI can be used safely with the use of appropriate workplace practices, including use of personal protective equipment, engineering controls and a medical surveillance program.

Toluene diisocyanate, TDI usage

Toluene diisocyanate (TDI) is used in the:

 Production of polyurethanes

 Consumer products

Manufacture of coatings



 Furniture, Polyurethane foam is used in household furniture


 Automotive seats

Bedding and carpet underlay

Packaging applications


In transportation applications, TDI helps produce lighter automobile parts, saving weight, which leads to improvements in fuel efficiency and thus energy conservation.

TDI had limited applications in food packaging and food processing with no expected human exposure from food-related uses.
