one. Adhesive Toughness
Look for high-tack adhesive that bonds immediately and permanently. Some tapes use acrylic adhesive for lengthy-lasting keep in extreme temperatures.
two. Temperature Range
Choose a tape with a broad functioning temperature vary, specifically for HVAC or industrial use. Some tapes purpose in ranges from -twenty°F to 300°File or bigger.
three. Thickness
Thicker tape commonly usually means more durability and improved overall performance in sealing and heat resistance. However, it could be more durable to use all over restricted corners.
4. UL Certification
For HVAC use, UL181A-P or UL181B-FX certification ensures the tape satisfies hearth and security specifications.
5. Moisture & UV Resistance
Make sure the tape is appropriate for outdoor use if needed. UV and humidity resistance will avert degradation after a while.
How to Apply Foil Tape The right way
Making use of foil tape is straightforward, but a few most effective techniques make certain maximum general performance:
Clear the Surface: Take out any Filth, oil, or moisture in advance of applying the tape.
