Material and construction Aluminum foil facing with acrylic adhesive for durable, heat-tolerant performance. Waterproof, heat-resistant, and easy to cut for fast field work. Paper-backed liner for easy peeling and accurate application. Key benefits and problem solving Creates reliable seals and patches that reduce air leaks, heat loss, moisture ingress and corrosion. Bonds well to non-adhesive and varied surfaces including metal, wood, paper and silicone, so you can use one tape across multiple materials. Wide temperature tolerance and weather resistance means a single tape suits both indoor and outdoor repairs. Performance and durability Temperature range: -20°C to 180°C. Resistant to flames, heat transfer, moisture, weather, certain chemicals and vapours, corrosion and rust. Designed for long-lasting adhesion under thermal cycling and damp conditions. Primary functions and compatibility HVAC tape for ducts: shielding, insulating, patching, sewing and sealing of joints and seams. Compatible with HVAC systems, appliances and automotive surfaces listed below without special primers. Common applications (practical scenarios) Repair a torn cold-air duct or reseal an HVAC seam to stop conditioned air loss and restore proper airflow. Patch around a dryer vent or refrigerator outlet to prevent moisture and heat escape while resisting high temperatures. Seal air-conditioning lines, bonnet heat shields or car vents to protect components from moisture and prevent corrosion. Why choose this tape Easy to cut to any length or angle and simple to apply—peel the liner, press into place and smooth for immediate adhesion. Robust aluminum face and acrylic glue combine thermal protection with reliable bonding to both smooth and low-energy surfaces. One product for multiple sealing, insulating and patching jobs across HVAC, appliance and automotive use. Specifications (as provided) Material: acrylic adhesive and aluminum foil.
