Aluminum ceramic fiber board is a lightweight refractory material processed with alumina-silica fibers for applications at temperatures up to 1430℃(2600℉)
Characteristic ：
♦ Fibers are bonded by binder
♦ Low density and low thermal conductivity
♦ Shorter heat up and cool down time
♦ Resilience and resistance to thermal shock
♦ Greater mechanical strength
♦ Can withstand gas flow velocity of 30 m/sec
♦ Even density, thickness
♦ Flexible and easy to cut or install
♦ Asbestos free
Application ：
♦Refractory lining for industrial furnaces in walls,roofs,doors,stacks,etc.
♦Combustion chamber liners,boilers and heaters
♦Back-up insulation for brick and monolithic refractories
♦Transfer of molten aluminum and other non-ferrous metals
♦Expansion joint boards
♦Barrier against flame or heat
♦Hot face layer for high velocity or abrasive furnace atmosphere
