摘要： The invention relates to a method for producing flat, hydrophilic, aliphatic polyurethane foams. The invention also relates to a flat, hydrophilic, aliphatic polyurethane foam obtained according to said method and to the use thereof as a wound dressing, incontinence product or cosmetic article. According to the invention, a prepolymer-component and a carbonic acid or carboxylate component containing water is produced, said components are combined and mixed, and the obtained mixture is applied to a flat substrate as a layer which has an even thickness. Directly after application, a perforated separation element is applied in a flat manner to the layer. Said applied layer then expands with the applied perforated separation element to form the flat polyurethane foam.
