SIGRAFLEX Foils and Laminated
Sheets for Heat Treatment
Applications
Products Markets / Applications Innovative Products Service

SIGRAFLEX graphite foils and laminated sheets are the first choice for a wide range of high-temperature applications in the heat treatment industry. For example, owing to its excellent properties, SIGRAFLEX is ideally suited for electrical heating elements and insulation in vacuum and inert gas furnaces.

Applications
  • Heating elements and heat shields for high temperature applications
  • Linings for melting crucibles and casting molds
  • Facings for hot pressing molds
  • Backing strips for soldering, welding and sintering work
  • Base material for vapor phase deposition of metal films
  • Protective material against laser beams
  • Packings and gaskets for hot gases, melts and heat-carrying oils

* SIGRAFLEX TH sheets may contain traces of dampness from atmospheric humidity during storage. If the sheets are suddenly heated up, escaping steam may cause the formation of bubbles on the surface, or even delamination of the SIGRAFLEX sheet. In order to avoid this damaging effect, we supply SIGRAFLEX sheets with small holes to allow the gas to escape in thermal applications.
