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).

  • Refractory Ceramic Fibre
  • Aluminosilicate
  • Aluminum Oxide
  • Amorphous Silica
  • Organic Binder
  • Organic Lubricant
