Heizfolie

Heizfolie, which translates to heating foil, is a thin, flexible heating element often used for surface heating applications. It typically consists of a conductive material, such as carbon, graphite, or a metallic alloy, printed or laminated onto a substrate. The substrate is usually a thin, insulating material like PET (polyethylene terephthalate) or Mylar. When an electric current is passed through the conductive layer, it generates heat due to electrical resistance.

The primary advantage of Heizfolie is its thinness and flexibility, allowing it to be integrated into various products and structures where conventional heating elements would be impractical. It can be cut to size and shaped to fit irregular surfaces. Common applications include heated mirrors, defrosting systems in vehicles, underfloor heating in buildings, heated textiles, and warming plates for food.

Heizfolie operates at relatively low voltages, making it a safe option for many uses. The heating temperature can be controlled by adjusting the voltage or by incorporating temperature sensors and controllers. Its energy efficiency is also a notable characteristic, as it directly heats the surface it is applied to, minimizing heat loss to the surrounding environment. The manufacturing process can involve printing techniques or lamination, making it suitable for mass production.
