TYPICAL USAGE of BR Fractalin:
BR Fractalin are excellent material to use as furnace lining.  Please contact Mattech for custom shapes.  Use in aluminum furnaces.   Fractalins have a higher service life compared to any fiber insulating board, due to their mechanical, and chemical stability at high temperatures. Other applications include hot plates, gas combustion burners, fire protection and stops. Due to high porosity, high strength, and high melting point BR Fractalin boards find many other uses.
