Foamfrax Insulation is a monolithic insulation system developed by Unifrax Corporation. Foamfrax is a three component system of specially conditioned bulk ceramic or soluble fibers, an inorganic binder, and organic foaming binder.
Foamfrax Insulation is used to insulate metal, refractory, or ceramic fiber surfaces at temperatures up to 2450 degrees F. It can be installed at rates in excess of 1000 board feet / hour and is used in a wide range of furnace linings and other insulating applications.
