Carbon and Graphite
Sandwich Boards

Carbon and graphite sandwich boards are manufactured with multi-layered, rigidized carbon or graphite felt. Graphite foil can be bonded to one or both faces.

Composite Rigid Felt Sandwich Boards and shapes be used for various purposes including insulation in vacuum furnaces, multi-crystalline casting furnace, and inert atmosphere furnaces.

Applications
  • Rapid furnace heat-up and cool-down.
  • Excellent temperature uniformity and furnace efficiency.
  • Excellent pump-down capabilities.
  • Easily shaped and installed.
  • Graphite foil surfaces significantly reduce erosion from high velocity gas flow.
