A process for the production of cellular polyurethane mouldings having a compact surface without using CFCs by reacting starting materials known per se which react to give polyurethane foams in closed moulds, using, as a blowing agent, carbamates obtainable from aliphatic amino alcohols and carbon dioxide, optionally in addition to further blowing agents. The process is particularly suitable for the production of foam sheathing of steering wheels, spoilers and of protective cushions in the passenger compartment of automobiles or for the production of shoe soles or shoe components. |
