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

 

[Bullet] Low thermal conductivity
[Bullet] High temperature stability
[Bullet] Density uniformity
[Bullet] Chemical resistant
[Bullet] Excellent resistance to thermal shock
      

It is 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. It is an ideal material for use in thermal areas experiencing vibration, mechanical stress, or strong erosion.
