Superwool Fibre


ThermalMax offers Superwool® Fibre blankets which are manufactured to offer excellent performance in high-temperature applications.

Our Superwool® Fibre blankets offer an alternative to traditional solutions due to its high refractoriness and excellent non-wetting characteristics with molten Aluminum. They also provide stability and resistance to chemical attack, however, exceptions include hydrofluoric acid, phosphoric acid and strong alkalies (i.e. NaOH, KOH). Our Superwool® Fibre blankets are unaffected by incidental spills of oil or water and their thermal and physical properties are restored after drying. These blankets are designed from pure raw Calcium-Magnesium-Silicate (CMS) raw materials and can be altered to achieve desired properties such as fibre diameter, shot content, fibre length and form.

Our Superwool® Fibre blankets are ideally suited to individual customer applications and are available in a wide range of thicknesses and densities. The maximum continuous use temperature depends on the application.

Typical applications include:

  • expansion joint construction
  • base seals
  • low-mass kiln car construction
  • tube seal fabrication
  • thermal and acoustical insulation
  • Superwool® HT Fibre (formerly Superwool® 607® HT)

The only biopersistent fibre available with a classification temperature of 1300°C.
