The present invention relates to a method for the production of a foam comprising at least one antimicrobial active agent, comprising the following steps: (1) producing a solution or dispersion comprising at least one pre-condensate 10 of the foam to be produced, and at least one antimicrobial active agent, (2) foaming the pre-condensate by heating the solution or dispersion from step (1) in order to obtain a foam having at least one antimicrobial active agent, and (3) tempering the foam obtained in step (2) at a temperature of 120 to 300°C. The invention further relates a foam produced in this manner, a molded part comprising such a foam, and the use of such a foam for the heat and sound insulation of buildings and building parts, for the heat and sound insulation of the interior spaces of vehicles and aircraft, for low temperature insulation, as an insulating wall covering, as an insulating and impact damping packaging material, as abrasively acting cleaning, grinding, and polishing sponges, in the hygiene sector, and as filter material. |
