| abstract |
The present invention relates to a layer composite, suitable as a wound dressing, comprising a foam layer (10) and a cover layer (20), wherein the cover layer (20) comprises thermoplastic polymer, preferably polyurethane, and is at least partially directly connected to the foam layer (10) and wherein the foam layer (10) comprises a polyurethane foam obtained by foaming and drying a composition comprising an aqueous, anionically hydrophilic polyurethane dispersion (I). The foam can be stabilized with ethylene oxide / propylene oxide block copolymers. The invention further relates to a method for producing such a layer composite and its use, for example as a wound dressing. |
