HVAC tape Selection Manual
HVAC Tape made of Aluminum foil but not only pure foil. Different thickness Aluminum foil as the backing, coating with different pressure-sensitive adhesive.
● Synthetic rubber resin adhesive, Also named Hot melt adhesive.
● Water-based acrylic adhesive.
● Solvent-based acrylic adhesive.

The thickness of Aluminum foil backing from 18um to 150um. But the actual common thickness is up to 50um. The thicker the aluminum foil is, the higher the tensile strength of the tape becomes.
But the thicker the foil, the more expensive it is. We usually use reinforced aluminum foil to increase its tensile strength but not much production costs.
Reinforced aluminum foil tape include:
● FSK tape
● Aluminum foil glass cloth tape
● Foil scrim tape
● PET laminated foil tape
