Corrugated metallic foil tape

Abstract

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.

         1 . A corrugated metallic foil tape prepared by a process comprising:
 obtaining a flat metallic aluminum foil tape having a top surface and a bottom surface,   obtaining a release liner having a pressure sensitive adhesive applied directly thereon,   applying the release liner to the flat metallic aluminum foil tape wherein the pressure sensitive adhesive is between the flat metallic aluminum foil tape and the release liner,   feeding the flat metallic aluminum foil tape with the release liner to a corrugator, and   corrugating the flat metallic aluminum foil tape with the release liner to form corrugations in the flat metallic aluminum foil tape and the release liner.   
     
     
         2 . The tape according to  claim 1 , wherein the corrugations in the corrugated metallic foil tape provide for expansion of the corrugated metallic foil tape in a circular or semi-circular shape. 
     
     
         3 . The tape according to  claim 1 , wherein the pressure sensitive adhesive is selected from the group consisting of acrylic, synthetic rubber, natural rubber, polyurethane, styrene-butadiene rubber (SBR), synthetic isoprene rubber, ethylene vinyl acetate copolymers, and silicone. 
     
     
         4 . The tape according to  claim 1 , wherein the corrugations are parallel to one another. 
     
     
         5 . A corrugated metallic foil tape having a top surface and a bottom surface prepared by a process comprising:
 obtaining a flat metallic foil tape,   obtaining a release liner having a pressure sensitive adhesive applied directly thereon,   applying the release liner to the flat metallic foil tape wherein the pressure sensitive adhesive is between the flat metallic foil tape and the release liner,   feeding the flat metallic foil tape with the release liner to a corrugator, and   corrugating the flat metallic foil tape with the release liner to form corrugations in the flat metallic foil tape and the release liner, wherein the corrugations are parallel to one another.   
     
     
         6 . The tape according to  claim 5 , wherein the corrugations in the corrugated metallic foil tape provide for expansion of the corrugated metallic foil tape in a circular or semi-circular shape. 
     
     
         7 . The tape according to  claim 5 , wherein the pressure sensitive adhesive is selected from the group consisting of acrylic, synthetic rubber, natural rubber, polyurethane, styrene-butadiene rubber (SBR), synthetic isoprene rubber, ethylene vinyl acetate copolymers, and silicone. 
     
     
         8 . The tape according to  claim 5 , wherein the flat metallic foil tape is an aluminum foil tape. 
     
     
         9 . A corrugated metallic foil tape prepared by the process comprising:
 obtaining a flat metallic aluminum foil tape having a top surface and a bottom surface,   applying a pressure sensitive adhesive to at least one of the top surface or the bottom surface of the flat metallic aluminum foil tape using a release liner having the pressure sensitive adhesive applied directly thereon, and   corrugating the flat metallic aluminum foil tape with the release liner to form corrugations in the flat metallic aluminum foil tape and the release liner.   
     
     
         10 . The tape according to  claim 9 , wherein the corrugations in the corrugated metallic foil tape provide for expansion of the corrugated metallic foil tape in a circular or semicircular shape. 
     
     
         11 . The tape according to  claim 9 , wherein the pressure sensitive adhesive is selected from the group consisting of acrylic, synthetic rubber, natural rubber, polyurethane, styrene-butadiene rubber (SBR), synthetic isoprene rubber, ethylene vinyl acetate copolymers, and silicone. 
     
     
         12 . The tape according to  claim 9 , wherein the corrugations are parallel to one another. 
     
     
         13 . The tape according to  claim 9 , wherein the release liner is applied to the flat metallic aluminum foil tape by lamination prior to corrugation. 
     
     
         14 . A corrugated metallic foil tape prepared by the process comprising:
 obtaining a flat metallic aluminum foil tape having a top surface and a bottom surface,   laminating a release liner having a pressure sensitive adhesive applied directly thereon to at least one of the top surface or the bottom surface of the flat metallic aluminum foil tape, and   corrugating the flat metallic aluminum foil tape with the release liner to form corrugations in the flat metallic aluminum foil tape with the release liner.   
     
     
         15 . The tape according to  claim 14 , wherein the corrugations in the corrugated metallic foil tape provide for expansion of the corrugated metallic foil tape in a circular or semicircular shape. 
     
     
         16 . The tape according to  claim 14 , wherein the pressure sensitive adhesive is selected from the group consisting of acrylic, synthetic rubber, natural rubber, polyurethane, styrene-butadiene rubber (SBR), synthetic isoprene rubber, ethylene vinyl acetate copolymers, and silicone. 
     
     
         17 . The tape according to  claim 14 , wherein the corrugations are parallel to one another. 
     
     
         18 . A corrugated metallic foil tape prepared by a process comprising:
 obtaining a flat metallic foil tape having a top surface and a bottom surface,   applying a pressure sensitive adhesive to at least one of the top surface or the bottom surface of the flat metallic foil tape using a release liner having the pressure sensitive adhesive applied directly thereon, and   corrugating the flat metallic foil tape with the release liner to form corrugations in the flat metallic aluminum foil tape and the release liner.
