Air conditioning duct tape is high-quality, high tensile strength aluminum foil coated in epoxy resin with strong, cold-weather solvent acrylic adhesive set on a easy-release silicone paper liner to preserve the adhesive and provide ease of use. Air conditioning duct tape uses a large amount of acrylic to resist drying out and becoming brittle, the aluminium foil backing also withstands temperature changes without shrinking and failing the way cloth-backed duct tape does.

The AC duct tape combines flexible foil for irregularly-shaped applications and excellent low temperature performance. Air conditioning duct tape conforms to fibrous ductboard and sheet metal ducts and works well in general-purpose heat shielding and light reflecting applications. The tape is used to seal joints and seams in ductwork to prevent air leakage and improve energy efficiency.


Aluminum Foil Tape Applications:

  • Fibrous ductboard, sheet metal ducts and blankets.
  • Applications requiring flexibility and good temperature performance.
  • General purpose aluminum foil tape for a variety of air conditioning ducts applications.

Aluminum Foil Tape Features:

  • Multi-purpose foil tape for HVAC industrial applications.
  • Nominal 40um aluminum foil is excellent for use on fibrous and sheet metal ducts.
  • Low moisture vapor transmission rate makes AFR4080 an excellent vapor barrier.
  • Service Temperature range from -20℃ to +80℃.
  • Flexible foil conforms well to curved or irregular surfaces.
  • Hand tearable and easy to install on site without special tools or application methods.
