Aluminum foil HVAC tape is a type of single-faced adhesive tape that is specifically designed to be used in heating, ventilation, and air conditioning (HVAC) systems. It is made from a layer of thickness 100um pure aluminum foil, has a strong adhesive backing coated with acrylic adhesive, protected by an easy-release silicone paper liner. That allows it to be easily applied to ductwork, pipes, and other components of HVAC systems.

The primary purpose of aluminum foil HVAC tape is to provide an airtight seal between two surfaces, which helps to prevent air leaks and improve the efficiency of the HVAC system. This aluminum foil tape is often used to seal joints and seams in ductwork, as well as to repair tears or punctures in the ducts themselves.

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

Aluminum Foil Tape Applications:

1. Sealing ductwork: Aluminum foil HVAC tape is commonly used to seal joints and seams in HVAC ductwork, ensuring that the system is airtight and preventing air leaks.

2. Insulation: Secure and seal insulation materials in HVAC systems, helping to maintain thermal efficiency and prevent heat loss.

3. Vapor barrier: It can act as a vapor barrier when applied to insulation materials, helping to control moisture and humidity levels within the HVAC system.

4. Repairs: Repairing damaged sections of HVAC ductwork, providing a strong and durable seal to restore the integrity of the system.

5. Reflective properties: The reflective nature of the aluminum foil tape can help to minimize heat loss and maintain consistent temperatures within the ductwork.
