Rigid Felt Boards

Our rigid graphite felt boards are available in the form of plates, cylinders and other form parts. Graphite felt is composed of lightweight carbon-bonded fibers, ensuring low thermal conductivity and vapor pressure with excellent insulating properties to reduce heat loss. They can withstand furnace temperatures up to 3500°C and are free of voids or hotspots found in other materials. They are easy to handle, install and machine. The felt boards are available in long-fibre and short-fibre versions.
