The foil backing is highly malleable, allowing it to conform to curved and irregular surfaces including fibrous duct board and sheet metal. The acrylic adhesive is formulated to hold across a wide service temperature range of -40 degrees F to 250 degrees F, making it suitable for both cold-weather installs and high-heat duct environments. Each roll measures 1.88 inches wide by 50 yards long. HVAC technicians and sheet metal workers are the primary installers of this product.\u003c\/p\u003e\n\u003cp\u003eThis tape is used in residential and light commercial HVAC applications for sealing duct seams, repairing foil-faced insulation, and patching sheet metal ducts. Its hand-tearable backing makes it practical for field use without requiring a tape dispenser or cutting tools. The easy-release kraft liner allows for clean, one-handed application during overhead or confined-space installs. It performs reliably in high-humidity environments such as crawlspaces, attics, and mechanical rooms where adhesive failure is a common problem with lower-grade tapes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2.0 mil dead soft aluminum foil backing conforms to irregular and curved duct surfaces\u003c\/li\u003e\n  \u003cli\u003eAcrylic adhesive rated for service temperatures from -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eHand tearable for fast field application without tools or dispensers\u003c\/li\u003e\n  \u003cli\u003eEasy-release kraft liner for clean, controlled adhesive placement\u003c\/li\u003e\n  \u003cli\u003eSuitable for high heat and high humidity environments\u003c\/li\u003e\n  \u003cli\u003eApplies to fibrous duct board and sheet metal duct substrates\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for sealing and patching fibrous duct board, foil-faced insulation, and sheet metal ductwork in residential and light commercial HVAC systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed HVAC technicians or sheet metal workers. Before applying, ensure the duct surface is clean, dry, and free of dust or grease to achieve full adhesive contact. Power down the air handling system before sealing supply or return duct sections. No special tools are required; the tape is hand tearable and can be pressed into place by hand or with a seam roller for improved adhesion on irregular surfaces.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTape Thickness\u003c\/strong\u003e: 2.0 mil\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.88 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 50 yards\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdhesive Type\u003c\/strong\u003e: Pressure-sensitive acrylic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Dead soft aluminum foil\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLiner Type\u003c\/strong\u003e: Easy-release kraft\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 31.55 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 11.13 inches x 11.13 inches x 12.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Roll\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 750351352024\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7100043755\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51345945821490,"sku":"7100043755","price":500.51,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310523896.jpg?v=1782067129","url":"https:\/\/voomisupply.com\/products\/3m-7100043755-aluminum-foil-tape-1-88-in-x-50-yd-hvac","provider":"Voomi Supply","version":"1.0","type":"link"}
