one. Adhesive Toughness
Glimpse for top-tack adhesive that bonds instantly and forever. Some tapes use acrylic adhesive for long-Long lasting keep in Serious temperatures.
two. Temperature Array
Go with a tape with a large working temperature assortment, especially for HVAC or industrial use. Some tapes perform in ranges from -20°File to three hundred°F or greater.
3. Thickness
Thicker tape generally means more longevity and superior effectiveness in sealing and heat resistance. Nevertheless, it could be more durable to apply about tight corners.
four. UL Certification
For HVAC use, UL181A-P or UL181B-FX certification ensures the tape satisfies hearth foil tape and safety standards.
five. Dampness & UV Resistance
Ensure the tape is appropriate for out of doors use if necessary. UV and dampness foil tape resistance will stop degradation after a while.
How to use Foil Tape Properly
