A process for producing a flame-resistant elastic soft polyurethane foam from a foam reaction component mixture of a polyol, a polyisocyanate, and a proportion of expanded graphite in the form of flakes as a flame retardant, includes initially admixing the flakes having a size on the order of magnitude of resultant foam cell walls with the polyol component. The flakes are incorporated to form at least part of the cell walls upon expansion of the foam. |
