Abstract: In the production of finely cellular rigid polyurethane foam by reacting (a) polyisocyanates with (b) compounds with at least 2 reactive hydrogen atoms in the presence of (c) blowing agent, (d) catalyst and optionally (e) ancillaries and/or additives, perfluoro compounds are used as blowing agent (c) and are emulsifier in (a) and/or (b) and water and air are removed from components (a) to (e) before reaction to the polyurethane. An Independent claim is also included for polyurethane foam produced in this way.
