ceramic fiber board is the lightweight refractory material processed with alumina-silica fibers for applications at temperatures up to 1430℃ (2600℉)
The ceramic fiber board is featured with high temperature stability, low thermal conductivity, consistent density, and excellent resistance against thermal shock and chemical attack.

Ceramic fiber board features:

Low thermal conductivity and Low shrinkage

Strong pressive strength

Resistant airspeed eroding

Smooth surface and Lightweight

Low impurity, even bulk density and thickness

Excellent mechanical strength and structural strength

High plasticity to make complex shape

Lightweight and easy to cut or install

Good erosion resistance

Shorter heat up and cool down time

Asbestos free

Ceramic fiber board applications:

Insulating backup to brick & castable

Furnace hot face lining

Use in industrial heat process equipment

High temperature gasket & seals

Flue & chimney linings in furnace & kilns

Molten metal trough covers

Expansion joint Industrial heat shields & thermal barriers

Industrial combustion chamber construction
