Air Duct Aluminum Foil Adhesive Tape 2'' 50mm 3'' 75mm

Aluminuim Adhesive Tape

Aluminium foil with an adhesive coat on one side.

Used on ductwork to provide an airtight seal, a sure and long lasting moistureproof and sealing-proof barrier against weather influences.
For maximum effect the surface must be clean and free of dust, moisture and other foreign contamination.

Coated on one face with an acrylic pressures sensitive adhesive.

Available in 50, 75 or 100 mm width.

Tehcnial Data Sheet of Aluminum Foil Adhesive Tape

Self-adhesive aluminium coated tapes from UNT Tape are especially cold and heat resistant, flame retardant, durable and waterproof or water resistant depending on the type. Our thin and thick aluminium adhesive tapes made of pure aluminium or aluminium composite film offer strong adhesive strength and high shear resistance. With these properties, our thermal adhesive tapes are the first choice for technical insulation or water vapor barriers. Their excellent workability at high and low temperatures makes them extremely construction site friendly.

Usage And Application of Aluminum Foil Tape 

Aluminum adhesive tape (commonly called aluminum foil tape) is a specialized pressure-sensitive tape with a high-purity aluminum foil backing coated on one side with acrylic, rubber, or silicone adhesive, often with a release liner for storage. It’s valued for thermal insulation, moisture sealing, heat reflection, EMI shielding, and chemical resistance, making it a staple across HVAC, construction, electronics, and automotive industries.

Key Applications
HVAC & Ductwork: Seal joints of foil-faced insulation, tape duct seams, patch insulation nail punctures, prevent air/moisture leaks.
Building & Piping: Insulate hot/cold water pipes, wrap duct insulation, seal roofing underlayments, radiant barrier installations.
Electronics & Appliances: EMI shielding for LCDs, laptops, and control panels; fixing heat sinks in refrigerators/air conditioners.
Automotive & Industrial: Exhaust heat shields, battery pack thermal management, chemical tank lining seals.

Usage & Selection Tips
Surface prep: Clean, dry, free of oil/dust for maximum adhesion; avoid applying at extreme low temperatures.
Adhesive choice: Acrylic for cost-effective general use; silicone for >120°C environments (ovens, industrial ducts).
