Pure Silica Fibre Felts, heat-resistant up to 1,200 °C
The pure silica fibre products provided by Final Advanced Materials have a proportion of silica greater than 99.95 %. They are made of continuous, non-porous and homogeneous fibres. Silica is not only one the most effective high-temperature materials but is also among the most ecological and reliable on the market.
Pure silica fibre felts are composed of silica fibre combined with polyvinyl alcohol. There is no shrinkage even with operating temperatures up to 1,000 °C and they maintain very low thermal conductivity as well as excellent mechanical properties. They can be used at temperatures up to 1,200 °C.
These felts are particularly appreciated in the aerospace industry for the insulation of engines thanks to their resistance to vibrations as well as their outstanding insulating and fireproof properties and their very long life. Their outstanding properties are also useful for domestic applications such as catalytic heaters and industrial furnace insulation.
The pure silica fibre felts are available untreated or with a polyvinyl acetate (PVA) binder. A calcined version is also possible. The calcination process removes the fibres on the surface, thus improving their performance and their resistance to heat.
For more information regarding the availability, refer to the technical data sheet.
