The present application is directed to pumpable thermally foaming filler compositions based on combinations of a liquid epoxy resin and a polyvinyl chloride resin and/or an acrylic resin powder and at least one alkali metal salt of a fatty acid containing 16 C-atoms or 18 C-atoms, wherein the alkali metal is calcium or zinc. These pumpable filler materials provide the advantage that they can be expanded to provide foam with high expansion values after humidity exposure/storage.The present invention further describes methods for filling closed spaces with the pumpable thermally foaming filler composition as well as vehicle parts which are obtainable with the indicated methods.
