HVAC foil tapes are single-faced adhesive tape of Aluminum Foil backing which is coated by Pressure-sensitive adhesive (PSA).
HVAC foil tape is a type of adhesive tape that is specifically designed for use in heating, ventilation, and air conditioning (HVAC) systems. It is made of a thin layer of aluminum foil backing, which is coated with a strong adhesive on one side. The tape is used to seal and join sections of ductwork, insulation, and other components in HVAC systems.
The aluminum foil backing provides several benefits. It is highly resistant to moisture, heat, and chemicals, making it suitable for use in various HVAC applications. The tape helps to create an airtight seal, preventing air leaks and improving the overall efficiency of the system. It can also be used for insulation purposes, as the foil backing reflects heat and helps to maintain temperature control. The shiny, UV resistant Aluminum foil backing offers an enhanced appearance, excellent reflective and flame retardant properties, and remains flexible to resist cracking and lifting around irregular or curved surfaces.
But the Aluminum foil is too thin, It is easy break because the resistance to external force impact ability is limited. So the various types of HVAC foil tape backing can be solute this problem:
FSK: Foil-scrim-kraft reinforced Aluminum foil backing for HVAC foil tape.
The middle layer is the Glass fiber layer double side coated with Flame-retardant adhesive, it increased tensile strength of FSK, and the Aluminum foil and Kraft paper are firmly bonded.
PSK: PP-scrim-kraft reinforced Aluminum foil backing for HVAC foil tape.
PSK uses a bleached white kraft paper that is laminated with a white polypropylene film and tri-directional fiberglass scrim. Glass fiber layer double side coated with Flame-retardant adhesive,and the Kraft paper and PP film are firmly bonded.
ASJ: All service Jacket reinforced Aluminum foil backing for HVAC foil tape.
The middle layer is the Glass fiber layer double side coated with Flame-retardant adhesive, it increased tensile strength of ASJ, and the Aluminum foil and White kraft paper are firmly bonded.
Tape applications:
HVAC foil tape is commonly used by HVAC professionals and homeowners for sealing ducts, repairing damaged insulation, and securing HVAC components.
Sealing joints and seams in ductwork
Repairing damaged ductwork
Insulating ductwork
Preventing air leaks
Blocking moisture from entering ductwork
