LUYANGWOOL 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 gasvelicities than ceramic fiber blanket. It is ideal for furnace,boiler duct and stack lining thanks to its low thermalconductivity and low heat storage, which makesthe shorter cycles times and quicker access for maintenance in the industrial furnaces possible.

 

LUYANG ceramic fiber board is a lightweight refractory material processed with alumina-silica fibres for applications at temperatures up to 1430C.
