Silicate Fibre Felt 1,200°C

Silicate fibre felt

Silicate Fibre Felts, up to 1,200 °C

S98 fibre are made of more than 98 % silica (S98) and have a silicate fibre base that allows them to withstand application up to 1,200 °C.

Silicate fibre products are inorganic, and contain no toxic substances (asbestos-free) or irritants. The good thermal and mechanical properties of these products make them excellent replacements for asbestos-based products. With a diameter ranging from 6 to 9 μm, these fibres pose no hazard to health.

Silicate fibre felts do not contain any organic binders. The fibres are mechanically bonded, which makes the felt compact, flexible and gives it a good hold during processing. 

In comparative terms, silicate fibre-based textiles have superior high-temperature resistance to biosoluble fibre textiles.

Applications of Silicate Felts

  • Heat insulation
  • Acoustic insulation
  • Component for thermal and fire protection
