1. Adhesive Power
Seem for prime-tack adhesive that bonds quickly and completely. Some tapes use acrylic adhesive for long-Long lasting keep in extreme temperatures.
2. Temperature Selection
Decide on a tape with a broad operating temperature array, specifically for HVAC or industrial use. Some tapes function in ranges from -twenty°F to 300°File or better.
three. Thickness
Thicker tape usually usually means much more sturdiness and much better functionality in sealing and warmth resistance. Even so, it might be more difficult to apply about tight corners.
four. UL Certification
For HVAC use, UL181A-P or UL181B-FX certification guarantees the tape meets fireplace and basic safety expectations.
5. Humidity & UV Resistance
Ensure the tape is ideal for out of doors use if wanted. UV and dampness resistance will prevent degradation after a while.
How to use Foil Tape Appropriately
