    Abstract: A process for the production of stable dispersions (I) of melamine in polyol components comprising high-mol. wt. compound(s) with at least two reactive hydrogens and optionally low-mol. wt. chain extenders/crosslinkers, blowing agents, catalysts, fire retardants and other additives etc.. In this process, melamine is used as fire retardant in combination with amine(s) (II) and unmodified and/or modified organic isocyanate(s) (III). Also claimed is a process for the production of fireproofed polyurethane (PU) foam, by reacting isocyanates as above with other components as above, using melamine dispersions (I) as fire retardant. Preferably the process comprises adding melamine as fire retardant, followed by amines (II) and then isocyanates (III). The polyol component contains 1-50 wt% melamine, preferably with a particle size of 1-100 microns. (II) comprise prim. and/or sec. aliphatic and/or cycloaliphatic amines, and (III) comprise aromatic isocyanates or prepolymers with NCO groups, each in amounts of 0.05-5 wt% based on the polyol component.
