Abstract:
A method for foaming or foam-coating a component, which comprises:selecting a conductive material as at least one material from the group consisting of soot, an ethoxylated amine, a monoglycol ester of a fatty acid, a diglycol ester of a fatty acid, and a polyglycol ester of a fatty acid;finely dividing the conductive material to form a finely divided conductive material;setting a polarity of a foamable material by mixing the finely divided conductive material into the foamable material to give the foamable material a polar state;inserting the foamable material in the polar state completely into cavities of a double-walled or multiple-walled component or applying the foamable material completely onto the component between a surface of the component and a decorative material; andthen heating the foamable material through microwave energy thereby expanding the foamable material to form a foam filling.
