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.
摘要:
The invention relates to a novel optical function layer and its production, the function layer imparting to materials coated with it protection against uv radiation while transmitting electromagnetic radiation of larger wavelengths. The function layer of the invention and the manufacturing method of the invention offer advantages over the state of the art by allowing very accurate and precise adjustability in the uv range of the relatively sharp absorption constant.
