Pure Silica Fibre Felts 1200°C

pure silica felt high temperrature insulation

Pure Silica Fibre Felts, up to 1,200 °C

Our pure silica felts contain 99.95 % SiO2. They are made from continuous, homogeneous and non-porous filaments. This material is not only one of the most efficient in terms of high temperature application, but also one of the safest and most ecological on the market.

Composed of silica fibres assembled with polyvinyl alcohol, they can be used in temperatures of up to 1,200 °C. Even at a continuous temperature of 1,000 °C, they do not shrink and retain a very low thermal conductivity and exceptional mechanical properties

Our felts are particularly popular in the aerospace industry for insulating engines thanks to their outstanding insulating and fireproof characteristics as well as their resistance to vibrations and their very long life. Their outstanding properties are also useful for domestic applications such as catalytic heaters and industrial furnace insulation.

Silica products are particularly valued for their exceptional dielectric properties, especially in the construction of radomes.

Applications of Pure Silica Felts

  • Insulation of industrial furnaces
  • Catalytic supports for heating systems
  • Replacement of asbestos and ceramic fibre
  • Thermal insulation in the manufacture of optical fibre
  • Engine insulation in aeronautics
