ABSTRACT:
A flexible polyurethane foam is made by reacting an isocyanate with a polyol in the presence of a foam-forming agent and a fire-retardant additive. The fire-retardant additive comprises melamine and this is used in conjunction with a polyol which is of the polymer-modified polyol kind, i.e. a polyol containing a polymeric substance such as a dispersed alkanolamine/isocyanate polyaddition product.
