Toluene diisocyanate reacts with diols to form linear polymers and triols to form cross linked polymers. Mixtures are used. (Note that ethylene glycol and glycerol are example alcohols.)

If a small quantity of water is added, this will hydrolyse some of the isocyanate functions to the amine and carbon dioxide. The liberated carbon dioxide will expand and cause the formation of polyurethane foam.
