Aluminum Foil Tape Description


Air conditioner aluminum foil tape is a type of adhesive tape specifically designed for use in air conditioning and heating systems. Air conditioner tape are single-faced adhesive tape of thickness 18um normal aluminum foil backing, coated by Solvent Acrylic adhesive (PSA), protected by an easy-release silicone paper liner, which allows it to adhere well to both smooth and irregular surfaces. These AC foil tapes has strong adhesion and excellent retention, and provides firm and reliable sealing and adhesion for the joints and seams of central air-conditioning duct (from -30 degrees to 150 degrees).

Air conditioner aluminum foil tape will be good aging stability, high resistance to UV, ozone and humidity, best useful in long-term, air-conditioner duct work applications. AC foil tape has a lot of application in wide range of industries with good chemical and heat resistance. Air conditioner foil tape can provide excellent steam barrier for wrapping the steam pipe to prevent the temperature from losing outwards. Greatly improve the thermal insulation performance.

Tape Applications:

AC aluminum foil tape is commonly used to seal seams and joints in ducts, pipes, and other components of air conditioning systems. This helps to prevent air leaks and improve energy efficiency.

AC foil tape can be used to repair damaged surfaces, such as holes in ducts or cracks in pipes. 

Air conditioner tape can also be used to isolate the harm of electromagnetic wave to human body, so as to avoid the influence of voltage and current on the function. In addition, it has a good effect on electrostatic discharge after grounding.

AFA 1855 aluminum foil tape can form a heat shield, which can optimize the working performance of the air conditioner, extend the service life of the air conditioner, and avoid the air conditioner from thermal radiation.

Tape Features:

Air conditioner tape backing provides excellent heat and light reflection.

High quality adhesive with super strong adhesion and holding power offers reliable and durable joints and seams sealing in air-conditioning ductwork application.

Low moisture vapor transmission rate makes AFA1855 an excellent vapor barrier.

Superior quick stick at normal temperatures with superior low temperature performance at freezing.

AC foil tape is easy to apply and remove. It can be cut to size with scissors or a utility knife.
