Ultra pure silica felts 1200°C

Our ultra pure silica felts contain 99.95% SiO2. Composed of silica fibers assembled with polyvinyl alcohol, they can be used in temperatures of up to 1200°C. Even at a continuous temperature of 1000°C, they do not shrink and retain a very low thermal conductivity and exceptional mechanical properties.

These 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.

Applications of Silica Felts

  • The aerospace industry 
  • The glass industry
  • Insulating industrial furnaces
  • Catalytic supports for heating systems
  • Replacement of asbestos and ceramic fibres
  • Thermal insulation in the manufacture of fibre optics
  • Insulation of engines in the aeronautics industry
