Abstract

A process for the production of mouldings having a density of at least 120 kg/m<3> from polyurethane foams having a compact surface by foam-moulding a reaction mixture comprising a) a polyisocyanate component, b) a reactive component containing groups which are reactive towards isocyanate groups, c) blowing agents and optionally d) further assistants and additives, where the blowing agents c) used are salts containing water of crystallisation, optionally in addition to further chemical or physical blowing agents, and the mouldings obtained by this process.
