The present invention is an article comprising a shaped rigid foam part; a heat activated foamable adhesive applied directly to at least a portion of the outer surface of the shaped foam part and an integral locating means. A second aspect of the invention is a method of forming a foam filled vehicle hollow member comprising, (a) inserting into a vehicular hollow member a rigid foam part comprised of a rigid foam having a heat activated foamable adhesive on at least a portion of the rigid foam insert and at least one integral locating means extending from a surface of the rigid foam, (b) engaging the locating means with the hollow member to locate the rigid foam part within the hollow member, and (c) heating the hollow member having the rigid foam part therein to a temperature and for a time sufficient to activate the heat activated expandable adhesive to form the foam filled vehicle hollow member.

What is claimed is: 1. An article comprising a shaped rigid foam part, a heat activated foamable adhesive applied directly to at least a portion of the outer surface of the shaped rigid foam part and an integral locating means wherein the integral locating means is a shaped indentation or protrusion in the rigid foam part; a second locating means partially molded into the rigid foam part wherein a portion of the second locating means also protrudes from the rigid foam part and which is adapted to locate the rigid foam part in the proper location of a hollow member, and further wherein the shaped rigid foam part has at least one adhesive dam on the surface of the shaped rigid foam part where said dam, upon expansion of the foamable adhesive, causes at least a portion of the article to be free of the foamable adhesive. 2. An article according to claim 1 wherein the second locating means is a locating pin, a metal tab, a protrusion having a pressure-sensitive adhesive or a magnet applied thereto, or an insert having threads adapted for receiving a screw. 3. An article of claim 1 wherein the shaped rigid foam is a polyurethane foam. 4. An article of claim 1 wherein the foamable adhesive is an epoxy adhesive. 5. An article of claim 1 wherein the foamable adhesive is an elastomeric adhesive. 6. An article of claim 1 wherein at least one of the locating means is adapted to hold the article in place mechanically. 7. An article according to claim 1 wherein the adhesive dam has a height that is essentially the same as the foamable adhesive's thickness.
