Aluminum Foil Tape Description


Aluminum foil duct tape is a type of tape that is specifically designed for use in heating, ventilation, and air conditioning (HVAC) systems. It is made of a backing material consisting of a thin layer of aluminum foil, which provides excellent heat and light reflection properties, and is coated with a strong adhesive. This aluminum foil tape is heat-resistant and durable, so it can withstand the high temperatures and pressures associated with HVAC systems. Additionally, the reflective properties of the aluminum foil can help to reduce heat transfer and improve energy efficiency.

Aluminum foil duct tape uses professional grade aluminum that resists most conditions including extreme temperatures, humidity, chemicals and UV degradation. Thickness 75um normal Aluminum foil backing, coated with Acrylic adhesive, protected by an easy-release silicone paper liner.

Aluminum foil duct tape is resistant to high temperature, good flame retardant, anti-aging and corrosion resistance. It is flexibility and durability, allowing it to conform to irregular surfaces and withstand varying temperature conditions. In daily use, the aluminum foil tape can be used as a repair tool to repair, wrapping, emergency maintenance and other home use.

Tape Applications:

Sealing air ducts: Effectively seals leaks and gaps in air ducts, preventing energy loss and improving HVAC system efficiency.
Repairing metal surfaces: Patches small holes and tears in metal ductwork, extending the lifespan of your system.
Insulating pipes and wires: Reflects heat away from pipes and wires, protecting them from damage and improving energy efficiency.
Moisture and water sealing: Creates a waterproof barrier around pipes, roofs, and other areas prone to moisture damage.

Tape Features:

Aluminum backing provides excellent resistant of humidity, UV degradation, chemicals and extreme cold and heat.
High quality adhesive to seal gaps in ducting and prevent moisture and emissions from seeping in or out.
Low moisture vapor transmission rate makes AFA75125 an excellent vapor barrier.
Service Temperature range from -30℃ to +150℃.
Conforms easily to irregular surfaces and tears readily for convenient application.
