Ceramic Fibre

BOARD

Ceramic Fibre Board is a rigid insulating material available in light, medium and heavy densities and manufactured using refined ceramic fibres, fillers and binders.

Ceramic Fibre Boards are ideal for use at elevated temperatures of up to 1400˚C as they exhibit excellent strength characteristics.

Ceramic Fibre Board is an ideal material for back-up insulation, flue linings, boiler ducts, furnace and kiln linings.

The structure of Ceramic Fibre Board lends itself to high definition machining and production of technically complex machined parts and shapes.

Other benefits include:

Low heat storage
Low thermal conductivity
Outstanding thermal shock resistance
Good tensile strength
Asbestos free
Excellent resistance to direct flame

USED IN

Furnace/Back-Up Lining
Metal Transfer/Casting
Heat/Flame Barriers

Hot Face Insulation for Burner Quarls
Expansion Joints
Combustion Chambers
Kiln Linings

Typical Composition

Refractory Ceramic Fibre in the form of bulk, chopped,blanket, blanket modules,board and shapes are made from inorganic amorphous glass fibre (RCF).
