Aluminum tape
Aluminum adhesive tape consists of a thin aluminum foil that is coated on one side with a mostly heat-resistant adhesive. The side coated with adhesive is protected from sticking together by wax paper. Aluminum adhesive tape is supplied in roll form.
Aluminum adhesive tape is available in different widths and strengths. Most often it is used in a thickness of approx. 25 µm to approx. 100 µm.
One advantage over adhesive tapes made of plastic is their high thermal resistance and durability. Plastic adhesive tapes become brittle over time when exposed to heat or cold.
use
Aluminum adhesive tape is widely used in heating and ventilation construction. The pipe insulation is wrapped with thin wires, which give the insulation the necessary support, and then fixed with aluminum adhesive tape. Joints and cut surfaces are also covered with it to improve the insulation value: If the joints were left open, a lot of heat would be lost through the exchange of air.
Use in electrical engineering
In electrical engineering, aluminum tape is occasionally used for shielding. To do this, if necessary, cover parts of the housing or openings with aluminum tape or self-adhesive aluminum foil. Instead of adhesive tape made of aluminum, copper adhesive tape is often used here; this has the advantage over aluminum adhesive tape that it can be soldered.
