The Properties of Aluminium Tape That Make It Stand Out From Other Tapes

17 Jul

Aluminium foil tape combines the weather-resistant sealing properties of adhesive tapes and the versatility of aluminium, making it one of the most widely used types of tape across a variety of industries today, including construction, manufacturing, automotive, HVAC industry, etc. Due to its great moisture and chemical resistance, light and heat reflectance, thermal conductivity, flame resistance and weatherability, it’s a great fit for many different applications. But what exactly is aluminium foil insulation tape?

Aluminium foil was “invented” in 1888 and it became available for commercial use just a couple of years later. It’s regarded for its protective properties and attractive appearance in containers and packaging. It was widely used in World War II to protect insulation, capacitors and packages. After the war, it became widely used across the aforementioned industries. Aluminium foil insulation tape features a specifically-engineered metal foil backing that adds to its malleable, rugged and conductive properties. Foil tape carriers feature aluminium and aluminium with glass, copper, lead, copper with tin and steel plating.

Having said that, aluminium foil tape is the most widely used type of foil tape in building and construction. When combined with the sealing power, aluminium foil tape provides durable, long-lasting sealing. So what makes aluminium the material of choice for this type of tape, and why is it regarded as one of the most versatile metal when compared to other metals? There are several advantages that aluminium has over most other commercially available metals, including:

  1. Being Lightweight – Aluminium is lighter when compared to many other metals, which is why it’s widely used in the manufacturing industry for a wide range of products, including fuel-efficient vehicles and accessories for vehicles. Additionally, it’s used in the manufacturing process of plane wings, due to the fact that it’s durable, yet flexible and lightweight
  2. Corrosion Resistant Properties – Aluminium is corrosion resistant, but you can improve its resistance properties even more by treating it with a variety of surface treatments
  3. Heat and Electricity Conduction – Aluminium provides outstanding electricity and heat conductivity, making it suitable for use in power transmission lines
  4. Odourless and Impermeable – Aluminium foil can be used for packaging sensitive items like medicine and food. It doesn’t release any odour or taste that can mix in the products you wrap inside it, and it’s also non-toxic. Additionally, it doesn’t let gases and liquid come out, not even the slightest aromas
  5. Ductile Properties – Aluminium can take a lot of stress, allowing it to be stretched into a hammered thin or wire, and it doesn’t brittle during and after the fact
  6. Heat and Light Reflectivity – Since aluminium is lightweight, it comes with great light and heat reflectivity, making it suitable for manufacturing items such as reflectors and rescue blankets
  7. Recyclable – Last but not least, aluminium is a sustainable material simply because it’s recyclable. In order to recycle it, you need to spend 5% of the energy required for its production

With these advantages in mind, it’s no surprise why many industries take advantage of aluminium foil tape. When combined with the adhesive properties of tape, you get a product that’s valuable and versatile in:

  1. The Packaging Industry – Initially used in World War II, aluminium foil tape provides exceptional sealing and securing properties against heat, vermin, moisture, etc.
  2. HVAC Systmes – Aluminium foil tape’s weather-resistant properties allow it to be placed under harsh temperatures and weather conditions, like high-humid areas and sub-zero temperatures. So if you need to seal ducts in heating, ventilating and HVAC systems, aluminium foil tape is your best bet
  3. Electrical Industry – The tape is also great for wrapping electrical insulation and cables thanks to its ability to safeguard temperature-sensitive materials
  4. Aerospace Industry – Aluminium foil tape is used to protect the wheels, windows, seams and everything else on an airplane during paint stripping
  5. Construction Industry – Aluminium foil tape can be used for a wide range of applications in the construction industry, such as repairing roofs and metal gutters, as well as for reinforced fibreglass insulation and mineral thermal wood
  6. Marine Industry – Due to its high moisture resistant properties, aluminium foil tape is great for sealing holes. In fact, cargo-carrying boats can be built completely out of aluminium foil

The adhesive material found on aluminium foil tapes can be either rubber, acrylic or butyl. Rubber adhesives offer exceptional tack and adhesion, but they don’t perform well in extremely cold conditions. On the other hand, butyl adhesives do great in extreme temperatures while keeping its flex qualities. Acrylic adhesives are the middle-ground between butyl and rubber and offer a good balance of tack, shear, adhesion and great resistance to thermal and UV degradation.

No matter what type of aluminium tape you end up choosing, you need to make sure it’s code compliant in order to pass inspection. It should comply to all the safety standards and qualities required for the job. The UL listings, for example, are key for performing work on HVAC systems.
