Go with a tape with a wide operating temperature selection, especially for HVAC or industrial use. Some tapes function in ranges from -20°F to 300°F or increased.
3. Thickness
Thicker tape commonly indicates extra sturdiness and better overall performance in sealing and heat resistance. Having said that, it could be more difficult to apply all around limited corners.
4. UL Certification
For HVAC use, UL181A-P or UL181B-FX certification guarantees the tape satisfies fire and security expectations.
5. Dampness & UV Resistance
Make sure the tape is appropriate for out of doors use if wanted. UV and dampness resistance will avoid degradation after some time.
