A carrier-free expandable filler insert for filling or sealing a hollow space or cavity is provided. The insert comprises a self-supporting continuous structure that may be produced by contour extrusion molding or injection molding a polymer matrix containing a polymer and/or polymer precursor and a latent blowing agent. The expandable filler insert is secured to the interior surface of a vehicle pillar, for example, using a fixing element that may be integral with the self-supporting continuous structure, the polymer matrix thereafter being activated and expanded by heating.
