Printable Toluene Diisocyanates Fact Sheet

Toluene-2,6-diisocyanate (2,6-TDI), toluene-2,4-diisocyanate (2,4-TDI), and toluene diisocyanate mixed isomers are the three forms of TDI commonly used in commerce. Acute exposure to TDIs can result in severe skin, eye, lung, and throat irritation. TDIs are possible carcinogens and may be teratogens (reproductive hazards). Workplaces are the primary source of exposure to TDIs, which are intermediary chemicals in the manufacture of polyurethanes. In Massachusetts, businesses used 7.4 million pounds of TDIs in 1998.
