Here are the top five reasons why our aluminum foil tape has become a best seller with so many of our customers:
1, UL 723 rated and meets International Building Code standards.
UL 723 is a test to measure the surface burning properties of building materials. In particular, it looks at the rate of flame spread and the density of smoke developed. To meet the International Building Code’s definition of fire-resistant, a composite material must have a flame spread rating no higher than 50.
DeYou Aluminum Foil Tapes are UL723 certified, which is worth noting because not all cloth-backed duct tapes or foil tapes are UL 723 rated.
2, Extreme cold and heat temperature versatility.
Our foil tape works in temperatures ranging from 248°F to -22°F and can be applied in temperatures ranging from 50°F to 105°F. Most tapes do not perform well in cold temperatures. Severe cold hardens the adhesive and diminishes sticking power of the tape. If you are applying the tape under cold conditions, it may not stick at all. Conversely, excessive heat can melt the adhesive on some tapes, rendering it useless.
3, Made with an acrylic adhesive.
Deyou’s all-weather aluminum foil tape is coated with a superior performance flame-retardant solvent acrylic adhesive, working equally well in extreme hot and cold weather conditions.
Why does this matter?
Well, most duct tapes are made with a rubber adhesive, which is known to delaminate from its backing in high-temperature applications. Other synthetic rubber adhesives may offer a greater range of temperature functionality, but they also have lower mechanical strength, weak aging resistance, and do not fare well under UV light. By creating a foil tape with an acrylic adhesive, we’ve achieved superior durability and longevity once they cure and stick to a surface.
4, A great alternative to mastic.
DeYou Aluminum Foil Tape are not messy (the biggest drawback of mastic), and they use less equipment (no need for old clothes, eye protection, gloves, paint brushes, drop cloths, etc.) It doesn’t need additional fasteners such as sheet metal screws, scrap metal, and drywall mesh to seal large areas and it can be used to seal holes in a furnace or air handler.
5, Able to hold up over time.
In construction, pressure-sensitive tapes are often used in areas that are concealed (like housewraps or foil-faced insulation). Which means they cannot be easily repaired or replaced. Due to its acrylic adhesive technology, DeYou Aluminum Foil Tapes offers better cohesion, adhesion, and thermal stability than a tape with a rubber adhesive.
