Hybrid Circuit Materials

Heatel™ Thick Film Pastes


Heatel™ for flat heating elements

DuPont thick film materials are trusted in a wide range of hybrid thick film circuits across automotive, telecom, biomedical and consumer applications.

The market for heating elements is steadily increasing. For a variety of applications stainless steel is the preferred substrate material. Thick film on steel substrates bring with them the advantages of low thermal mass, meaning quicker-heat up rate, improved controllability and therefore economy to the customer. It exhibits improved ability to select and control the resistance and TCR (Temperature Coefficient of Resistance) of the element itself, the potential for incorporating additional functionality on the element, for example, printed temperature sensors or control circuitry as well as rapid design flexibility and prototyping.
