Corrugated metallic foil tape
A metallic foil tape having a top surface and a bottom surface with an adhesive applied to at least one of the top surface or the bottom surface of the metallic foil tape and corrugations in the metallic foil tape providing for expansion of the corrugated metallic foil tape in a circular or semi-circular shape. The corrugated metallic foil tape is suitable to be applied to contoured or three-dimensional surfaces, and is particularly suitable for use in sealing or joining components of heat, ventilation, and air conditioning (HVAC) units.
