ABSTRACT:
A thin-walled structure (e.g., an end cone insulator (12) and/or a mounting mat) (12) comprising insulating material suitable for insulating portions (e.g., an end cone) of a pollution control device (16) and/or mounting material suitable for mounting a pollution control element in a pollution control device (16) (e.g., a catalytic element in a catalytic converter, a filter element in a diesel or gasoline engine exhaust filter, etc.). The thin-walled structure can comprise an insulating material and/or mounting material in the form, for example, of a sheet, mat (12) or three-dimensional thin walled structure (e.g., a single piece or multiple piece three dimensional end cone insulator). (12) An intermediate adhesive (18) (e.g., a heat activated adhesive, hot melt adhesive and/or adhesive-like thermoplastic material) is bonded to at least one major surface of the thin-walled structure so as to coat and penetrate into the at least one major surface. The intermediate adhesive (18) at least mechanically bonds to the thin-walled structure. A pressure sensitive (20) adhesive is bonded to the intermediate adhesive (18) and used to secure the thin-walled structure in place in the pollution control device (16).
