1. Adhesive Toughness
Glimpse for top-tack adhesive that bonds immediately and permanently. Some tapes use acrylic adhesive for lengthy-lasting keep in Serious temperatures.

2. Temperature Range
Decide on a tape with a broad running temperature assortment, especially for HVAC or industrial use. Some tapes functionality in ranges from -20°F to three hundred°File or better.

3. Thickness
Thicker tape generally means additional toughness and greater effectiveness in sealing and heat resistance. Nevertheless, it could be more difficult to use all over tight corners.

four. UL Certification
For HVAC use, UL181A-P or UL181B-Forex certification guarantees the tape satisfies fire and basic safety requirements.

five. Moisture & UV Resistance
Make sure the tape is ideal for out of doors use if necessary. UV and humidity resistance will prevent degradation after some time.
