Ceramic Fibre Fabrics, up to 2,000 °C
Final Advanced Materials offers an innovative continuous polycrystalline ceramic fibre. The metallic oxides at the heart of its composition ensure that the processing of this fibre into ceramic textile is particularly simple. The resulting mechanical and thermal performances exceed those of other fibrous materials, including aramid, silica, quartz or even glass.
Primarily composed of alumina (Al2O3) at different percentage, our ceramic fabrics can withstand operating temperatures up to 1,400 °C and peak temperatures up to 2,000 °C. They are mainly used in the industry as heat shield or fire barrier.
The ceramic fabrics provided by Final Advanced Materials are untreated. A version with a heat cleaned finish is available to limit irritations for customised applications as well as flying fibres and the amount of smoke produced during exposure to high temperatures. Ceramic fabrics are also available with a heat treated finish. This treatment prevents the physical degradation of the fibre when it is subjected to hot and humid conditions for an extended period.
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%.
