Abstract
The invention relates to a process for the production of water-blown, finely cellular rigid foams containing urethane groups and/or isocyanurate groups by the reaction of polyisocyanates with a polyol component in the form of an emulsion. The invention also relates to open-cell polyurethane foams which are foamable in the mould.
