IMS Strong Boards are produced from refractory fibre compositions specailly developed to give rigid, self-supporting boards with excellent high temperature properties.

IMS strong board is designed for use in applications requiring higher rigidty than blanket forms. Because of its higher density, it offers improved thermal insulation properties and good abrasion resistance.

IMS strong boards are manufactured using our vacuum forming process. The process allows the production of white boards in a wide dimensional choice, offering excellent homogeneity throughout the thickness which allows for high definition machining of the board.

IMS strong board is produced by the additon of selected refractory fillers to the ceramic fibre in order to improve its mechanical properties. Strong board has two times the strength of 1260 board, both when measured fired and unfired.

All board fomualations contain a small amount of organic binder to improve the cold handling strength and this burns out on first firing at approximately 200-300°C. Heat treatment can be made to burn the organic binders on special request.

Applications:

  • Iron and Steel- Expansion Joints, back-up insulation, heat shields and mould base insulation
  • Non-ferrous – Tundish and launder covers in the casting of copper and copper-based alloys
  • Ceramics – Hot-face lining for kilns and in construction of LTM kiln cars.
  • Glass – Back-up insulation in melting furnaces and protection of burners.
  • Furnance Building – Hot-face lining material ( alternative to blanket); back-up to solid refractories; expansion joints.
  • Light industry – Lining combustion chambers in industrial and domestic boilers
  • Petrochemical- High temperature heater lining- hot face material

Advantages

  • Rigid, self-supporting boards
  • Low thermal conductivity
  • Good abrasion resistance
  • Low heat storage
  • Resistant to thermal shock
  • Not wetting when in contact with most molten non ferrous metals ( including aluminium)
  • Good resistance to spalling
  • Can be easily cut and shaped
