Appear for high-tack adhesive that bonds instantaneously and completely. Some tapes use acrylic adhesive for extended-lasting hold in extreme temperatures.
two. Temperature Vary
Choose a tape with a broad functioning temperature array, specifically for HVAC or industrial use. Some tapes operate in ranges from -20°F to three hundred°File or increased.
3. Thickness
Thicker tape typically implies a lot more durability and better overall performance in sealing and warmth resistance. On the other hand, it might be tougher to use all over restricted corners.
4. UL Certification
For HVAC use, UL181A-P or UL181B-Forex certification guarantees the tape satisfies hearth and security requirements.
five. Dampness & UV Resistance
Ensure the tape is ideal for out of doors use if essential. UV and moisture resistance will reduce degradation after a while.
How to Apply Foil Tape Effectively
