1. Adhesive Strength
Look for high-tack adhesive that bonds instantly and permanently. Some tapes use acrylic adhesive for long-Long lasting keep in Extraordinary temperatures.
two. Temperature Array
Go with a tape with a large working temperature assortment, especially for HVAC or industrial use. Some tapes function in ranges from -twenty°File to 300°F or higher.
three. Thickness
Thicker tape commonly signifies far more sturdiness and much better overall performance in sealing and warmth resistance. Having said that, it might be tougher to use all-around restricted corners.
4. UL Certification
For HVAC use, UL181A-P or UL181B-Forex certification assures the tape meets hearth and security standards.
five. Moisture & UV Resistance
Make sure the tape is appropriate for outdoor use if wanted. UV and dampness resistance will prevent degradation eventually.
How to Apply Foil Tape Correctly
