A rigid, high temperature board made from bulk ceramic fibers (alumina & silica ) and organic bonding agents.

 

[Bullet] Low thermal conductivity
[Bullet] High temperature stability
[Bullet] Excellent resistance to thermal shock
[Bullet] Ideal for use in areas experiencing vibration, mechanical 
     stress, or  strong  erosion    
[Bullet] Easily Machined 
[Bullet] Higher mechanical strength than lower density LD material
 

Used as rigid high temperature seals and gaskets, baffles and muffles, flue and chimney linings in furnaces and kilns, infrared elements supports, trough and distribution linings for conveying molten metals, refractory backup, hot gas duct linings and furnace linings.
