摘要： A method of producing a hydrophilic polyurethane foam structure containing inert activated carbon particles, includes the steps of: (a) providing a water phase containing a surfactant and dispersed inert particles; (b) providing a isocyanate-terminated polyether having functionality of more than 2; (c) mixing the water phase and the isocyanate-terminated polyether, immediately transferring the resulting mixture to a mould or a continuous web, whereby a foam structure is obtained; and (d) drying the foam structure until it has a moisture content of at most 10% (wt). A foam structure produced by the method and a wound dressing containing the foam structure are also disclosed.

摘要： A method of producing a hydrophilic polyurethane foam structure containing a silver salt, chosen from the group of silver sulphate, silver citrate, silver acetate, silver carbonate, silver lactate and silver phosphate, or a mixture of these salts includes the steps of (a) providing a water phase containing a surfactant, and at least one silver salt, wherein the at least one silver salt is dispersed in the water phase; (b) providing a isocyanate-terminated polyether having functionality of more than (2); (c) mixing the water phase and the isocyanate-terminated polyether, immediately transferring the resulting mixture to a mould whereby a foam structure is obtained; and (d) drying the foam structure until it has a moisture content of at most 10% (wt). The hydrophilic polyurethane foam structure produced by the method and a wound dressing containing the foam structure are also described.
