Details

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
