Ceramic fibre products

You can use this material for insulation up to 1,850 °C. Because of the chemical element weight ratio, the crust of the earth contains more than 82 % oxygen, silicone and aluminium. The inorganic textured ceramic fibre is manufactured from this raw material combination; therefore, it is fire-resistant and thermally insulating. State-of-the-art chemical technology allows these fibres to be produced by melting various oxides at high temperatures.

Polycrystalline wool

Polycrystalline wool (aluminium oxide wool), or PCW wool in short, is produced from aqueous spinning solutions in the sol-gel process. PCW wool consists of fibres that have an aluminium oxide content (Al2O3) greater than 70 % by weight. The sol-gel process first results in water-soluble green fibres, which are then crystallised by heat treatment. This kind of wool is usually used at operational temperatures of more than 1,300° C.

Application fields are for example:

  • Furnace construction
  • Automobile manufacturing
  • Ceramics industry


  • Paper
  • Fleece
  • Plates
