毒性A designated hazardous waste (EPA). It is a colorless to yellow solid, melting at about 20°C. TDI and MDI (diphenylmethane diisocyanate) are used in the manufacture of polyurethane foams by reaction with polyhydroxy compounds. These foams are used for insulation, upholstering, etc. Exposure is commonly by inhalation of the vapor. Both TDI and MDI can cause irritation of eyes and mucous membranes, in severe cases leading to pulmonary edema. Sensitization to TDI is common and frequently rapid, leading to an allergic reaction and some loss of lung function. In the United Kingdom, the threshold limit value is 0.02 ppm for not more than 20 min, or 0.005 ppm for 8 h.
