Special Shapes


Nutec Fibratec* Ceramic Fiber Special Shapes are available in a wide variety of shape configurations.

These shapes are processed from alumina silica fibers for applications at temperature up to 1537°C (2800°F). To match

Nutec Fibratec* Special Shapes to specific applications, material compositions can be varied with different fillers and chemicals to produce special characteristics such as high strength, density and molten metal non-wetability.

  • Low thermal conductivity saves fuel.
  • Low heat storage, reduces cycle times.
  • Light weight-replaces heavy back-up insulations, less steel required.
  • Excellent thermal shock resistance.
  • Resistant to hot gas erosion.
  • Resists most chemical attacks.
  • Easy to cut, handle and install.
  • Low sound transmission.
  • Resists penetration by molten aluminum and other non-ferrous metals.
  • Contains no asbestos.

Typical Applications
  • Tundishes, melting crucibles and hot tops for alloy melting.
  • Heat insulation for industrial heaters.
  • Small furnaces.
  • Riser sleeves for foundries.
  • Head boxes and lounders for continuous sheet casting.
  • Die casting ladles.
  • Combustion Chambers.
