Descriptions
ceramic fiber board is manufactured and designed for the thermal applications requesting high demands on rigidity, the thermal insulation properties and abrasion resistance of ceramic fiber board have been further improved due to the higher density. Ceramic fiber board is a vacuum formed product that resists higher gas velocities than ceramic fiber blanket. It is ideal for furnace, boiler duct and stack lining thanks to its low thermal conductivity and low heat storage, which makes the shorter cycle times and quicker access for maintenance in the industrial furnaces possible.
Features
High rigidity and light weight
Low thermal conductivity
Resistance to thermal shock and gas erosion
Easy cutting and engineering, mechanical flexibility
Resists penetration by molten aluminum and other non-ferrous metals.
Typical Applications
Refractory lining for industrial furnaces
Combustion chamber liner, boilers and heaters
Back-up insulation for monolithic refractories
Transfer of non-ferrous metals
Expansion joint boards
Barrier against flame
