FINE-CELL, WATER-DRIVEN RIGID EXPANDED POLYURETHANES

The invention relates to a method for producing water-driven, fine-cell rigid foams containing urethane and/or isocyanurate groups by reacting polyisocyanates with a polyol component in the form of an emulsion. The invention also relates to foam-mouldable open-cell polyurethane foams.
