one. Adhesive Strength
Appear for high-tack adhesive that bonds instantaneously and permanently. Some tapes use acrylic adhesive for extended-lasting maintain in Severe temperatures.
2. Temperature Assortment
Pick a tape with a wide operating temperature range, specifically for HVAC or industrial use. Some tapes functionality in ranges from -twenty°F to 300°File or bigger.
three. Thickness
Thicker tape frequently means more durability and superior general performance in sealing and warmth resistance. However, it could be more durable to use all around restricted corners.
4. UL Certification
For HVAC use, UL181A-P or UL181B-Forex certification makes certain the tape fulfills fire and safety standards.
five. Dampness foil tape & UV Resistance
Make sure the tape is well suited for outside use if required. UV and humidity resistance will avert degradation with time.
How to Apply Foil Tape Properly
Implementing foil tape is simple, but a number of greatest methods make sure most general performance:
Clear the Surface: Take out any Grime, oil, or humidity in advance of applying the tape.
Evaluate & Reduce: Pre-evaluate the length you have to stay away from squander.
Push Firmly: Make use of a squeegee or press Software to bond the tape securely to your floor.
Overlap Edges: For ducts or seams, marginally overlap Every part for a decent seal.
Steer clear of Stretching: Stretching foil tape can weaken the adhesive and compromise overall performance.
