Alper: polyester ultra-flat heating elements

131

The Alper ultra-flat PET (polyester) heating foils allow to reduce the thickness of the heating elements (min. 0.2 mm). These resistances are produced by screen printing, initially depositing silver-based tracks, for the transport of electric current, and afterward a layer of conductive and heating ink. The continuous search for new formulations of heating inks has allowed Alper to make the production capacity and the development of new products based on customer specifications extremely flexible. The technology allows to reduce the tooling costs and any small changes on the required powers (+/- 20%) only by changing the composition of the heating inks.
