one. Adhesive Toughness
Glimpse for top-tack adhesive that bonds right away and forever. Some tapes use acrylic adhesive for extensive-Long lasting keep in Serious temperatures.
two. Temperature Selection
Opt for a tape with a large working temperature variety, especially for HVAC or industrial use. Some tapes function in ranges from -twenty°File to 300°File or bigger.
three. Thickness
Thicker tape normally signifies a lot more durability and better performance in sealing and warmth resistance. On the other hand, it might be tougher to use all around tight corners.
four. UL Certification
For HVAC use, UL181A-P or UL181B-FX certification ensures the tape satisfies hearth and safety criteria.
5. Humidity & UV Resistance
Ensure the tape is suitable for out of doors use if foil tape necessary. UV and humidity resistance will avert degradation with time.
How to use Foil Tape Accurately
Applying foil tape is simple, but a couple of most effective procedures ensure greatest overall performance:
Clean up the Surface area: Take out any Grime, oil, or dampness prior to making use of the tape.
