Polyurethane(or polyisocyanate) resins are produced by the reaction of a diisocyanate with a compound containing at least two active hydrogen atoms, such as diol or diamine. Toluene diisocyanate(TDI), diphenylmethane diisocyanate(MDI) and hexamethylene diisocyanate(HDI) are frequently employed. They are prepared by the reaction of phosgene with the corresponding diamines...  8, fiche 1, Anglais, - 1%2C1%26rsquo%3B%2Dmethylenebis%284%2Disocyanatobenzene%29

Isocyanates and polyisocyanates include a number of chemical products used in the manufacture of plastic foams, synthetic rubber, etc. Some are sufficiently toxic or lachrymatory to need classification as Poisonous articles, Class B or C, particularly isocyanates in pure form. Others may need to be classified as combustible liquids, flammable liquids, corrosive materials, or ORA.A., depending on their characteristics, and a number may be non-hazardous in transportation.  1, fiche 5, Anglais, - polyisocyanate
