Silicate Fibre Fabric, heat-resistant up to 1,100 °C
Silicate is a mineral made of silicon dioxide (SiO2) and other metallic oxides, such as calcium, magnesium, aluminium, etc. Silicate fibre-based textiles offer different thermal, physical and mechanical properties depending on their level of silicon dioxide.
Silicate fibre is inorganic and contains no toxic substances. The good thermal and mechanical properties of this fibre make it an excellent alternative to ceramic fibre. These fibres pose no health risk when handling with its diameter of 9 μm and can withstand high temperatures better than glass or basalt fibres.
Silicate fibre fabrics offer great mechanical strength and chemical resistance. They also have excellent thermal resistivity. They are therefore suitable for high-temperature applications, such as the assembly of protective covers against sparks and metal splashes.
The silicate fibre fabrics proposed by Final Advanced Materials have at least 94 % of silicon dioxide. These fabrics are untreated or available with a vermiculite coating. This treatment enhances the properties of the textiles, including their resistance to abrasion or to peak temperatures. A pre-setting is also possible in order to stabilise textiles through the action of heat. Moreover, different declinations of the silicate fibre are available for silicate fibre fabrics.
For more information regarding the availability, refer to the technical data sheet.

FAQs that can help you in this category
Final Advanced Materials offers a very wide selection of fabrics which can withstand temperatures ranging between -72°C and +2,000°C. For applications reaching temperatures as high as 550°C, fibreglass-based fabrics are the most versatile. They combine high mechanical and chemical resistances and are also effective electrical and thermal insulators. For applications with a continuous exposure to temperatures over 500°C, fabrics made from basalt fibre (800°C), silicate fibre (1,000°C) or ceramic fibre (1,300°C) are recommended. The choice of fabric depends on the desired application. Whether for insulation or protection, the service conditions are a determining factor for the choice of fabric.
The Zetex and ZetexPlus fabrics produced by Final Advanced Materials are both high-temperature fibreglass fabrics, used for thermal protection or insulation applications. Zetex fabrics are suitable for standard uses, with a resistance to temperatures of 540°C in continuous service and up to 700°C short-term. ZetexPlus fabrics are given a vermiculite-based treatment which improves their resistance to abrasion and mechanical stresses, while enabling them to withstand high temperatures, 815°C in continuous service, and up to 1,095°C short-term. The choice between these two materials therefore depends primarily on the working conditions.
Final Advanced Materials offers a wide range of products for extreme applications. Ceramic fibre-based and silicate fibre-based textiles are mainly used to manufacture parts in the aeronautical and aerospace sector.
They have an excellent thermal shock resistance, and can withstand exposure to temperatures of over 1,200°C short-term. These products are available in a wide range of forms, such as fabrics, braids, sleeves, tapes and non-wovens.
The ceramic fibre fabrics and the silica fibre fabrics offered by Final Advanced Materials are designed for the most extreme applications. When made into a fabric, ceramic fibres have a better stability at high temperature than silica-based fibres. Silica fibres have inferior mechanical properties and have a high shrinkage rate of 7 to 12%. It is however possible to thermally treat silica fabrics to reduce this shrinkage to only 1 to 4%.
