The invention relates to a method for producing flat, hydrophilic, aliphatic polyurethane foam materials. The invention further relates to the flat, hydrophilic, aliphatic polyurethane foam material produced according to the method and the use thereof as a wound dressing, incontinence product, or cosmetic article. The invention provides that a prepolymer component and a carbonic acid and/or a carboxylate component containing water be produced, that said components be combined and mixed, and that the mixture thus obtained be spread on a flat substrate in a layer of even thickness. Subsequently, the layer of the mixture thus spread expands to a flat polyurethane foam material having a layer of even thickness. |
