Aluminum Foil Tape Description


Air duct aluminum foil tape is a type of adhesive tape specifically designed for sealing and repairing air ducts in HVAC systems. It is made of a durable aluminum foil backing and coated with a strong adhesive on one side. Aluminum foil is treated on one side with silicone for easy release on unwind. The aluminum foil backing provides excellent heat and moisture resistance, making it suitable for sealing joints, seams, and gaps in air ducts.

Air duct aluminum foil tape is commonly used to prevent air leaks, improve energy efficiency, and maintain proper airflow in HVAC systems. The tape is one of your go-to tools for joining and sealing joints, connections, and seams on rigid fiberglass ductboard and flexible air duct. Air duct aluminum foil tape uses acrylic adhesive to resist drying out and becoming brittle. The metal foil backing also withstands temperature changes without shrinking and failing the way cloth-backed duct tape does.

Tape Applications:

Air duct aluminum foil tape designed for fixing aluminum cooling tubes in the refrigeration industry, holding electric heat tracing cables, general purpose sealing and holding applications, moisture barrier, electroplating, Home appliance industry, Automotive industry, Aerospace industry.

Tape Features:

The self wound foil tape will be offer good tack and adhesion to width range of temperature (from -30 degrees to 150 degrees).The aluminum foil tape will be good aging stability, high resistance to UV, ozone and humidity, best useful in long-term, outdoor applications.
