In a process for the production of a flame-resistant, elastic soft polyurethane foam from a foam reaction mixture containing a polyol and polyisocyanate and containing expandable graphite as flame-inhibiting agent, it is proposed according to the invention, in order to prevent after-swelling with danger of subsequent spontaneous combustion, that melamine in a prespecified amount be admixed with the foam reaction mixture in addition to the expandable graphite. |
