Silver-containing foam structure

foam structure containing silver. The present invention relates to a method for producing a hydrophilic polyurethane foam structure containing a silver salt, selected from the group consisting of silver salt, silver citrate, silver acetate, silver carbonate, silver lactate and silver phosphate, or a mixture of these salts. the method comprising the steps of (a) providing an aqueous phase containing a surfactant, and at least one silver salt, wherein the at least one silver salt is dispersed in the aqueous phase; (b) provision of an isocyanate-terminated polyether having a functionality of more than 2; (c) mixing said aqueous phase with said isocyanate-terminated polyether, immediately transferring the resulting mixture to a mold, whereby the foam structure is obtained; and (d) drying said foam structure until its moisture content is at most 10% (by weight). the invention also provides a polyurethane foam structure produced by the method and a dressing containing the foam structure.
