Applications and Uses of Foil TapesJune 22, 2018
Metals and tacky adhesive strips mix to create foil tapes. What properties does a product inherit from this liaison? For starters, the tape gains metallic strength. It’s also innately conformable. What’s more, the material is chemically and thermally resilient, capable of fending off moisture, and it somehow manages to look good while it hangs tough. In light of these metal-centric features, what applications are best served by this product range?
Used to Seal HVAC Ducting
All of those square metal segments, they’re vibrating because of a rush of warm air. The panels bulge and pop, and then they’re pulled inwards as the pressure differential changes. Foil tapes seal the ducts after they’ve been fastened together. The metal strips stop air leaks, hold firm when vibrations propagate along the ducting channels, and they maintain their adhesive properties, even when damp air conditioning streams accumulate in the duct flanges.
An Insulation Binder
Shifting over to a hot boiler room, perhaps the site that those ducts came by their warm air, heat-reflective aluminium foil is parted from a release liner. A pressure-sensitive adhesive touches the insulating. There’s already a coating of aluminium covering the insulation tubes, so the flexible metal tape easily bonds the jointed sections in place. Capable of sealing boiler flue pipes, the product referenced here is designed to handle 315°C of searing heat. Metal durability and a talent for thermal reflectivity work in concert with a silicone-based adhesive to really assure a mechanically reliable seal here, one that’s also moisture resistant.
Insulating Electrical Tapes
Covered in laminated acrylic polymers, foil tapes are commonly used as flexible electrical insulators. Acting as a secondary layer of plastic protection, several coated conductors can travel under the tape and be guided through control panels. Even in car dashboards, the foil tape is there, tidily directing dozens of system wires.
Conducting Foil Tapes
Flexible metal strips are commonly applied as electrical project assets. The conducting copper or aluminium rolls function as grounding strips, die cut electronic circuits, and radio frequency or electromagnetic shields. Essentially, the shiny material can be cut and made to function as a flexible printed circuit board. Static discharge and signal disrupting electrical noise are both defeated by this highly conformable shielding envelope.
From construction to aerospace applications, foil tapes are everywhere. Built to be mechanical tough and UV resistant, these traits make the metal film perfect as an outdoor construction resource or as a marine-grade sealant. Then, up above the clouds, lightweight aluminium foils are protecting conductors, sealing aircraft ducts, and helping the latest satellites orbit the Earth.
