Rigid felt • Online Furnace Services Ltd

Online Furnace’ rigid felt comprises layers of graphitised PAN felt which have been impregnated and bonded together. They are then heat treated to 1800ºC. Rigid felt can be supplied with either graphite foil or CFC bonded to the board. CFC clad board offers unsurpassed board lifetime, through its unequalled resistance to gas erosion in today’s high pressure gas quench furnaces.
