Basalt Fibre Fabrics, up to 800 °C
Basalt fibre fabric has properties that are far superior to glass fibre. Basalt fibre products offer extremely great resistance. Their thermal and mechanical properties are far superior to glass fibre's. Heavier than carbon, they are still less expensive.
Basalt is a dark non-crystalline rock that comes from volcanic magma. It can be used for applications involving peak temperature up to 800 °C as well as operating temperatures up to 700 °C. Basalt remains flexible and easy to handle, even if the product loses its mechanical properties and becomes rigid under excessive tension. It resists acids and bases as well as UV and is waterproof.
Basalt fibre fabrics are particularly popular in the automotive sector, as protection for motor components and insulators for exhaust pipes. Coated versions are ideal for fire barriers whereas uncoated versions are used as matrix in the manufacture of composites.
At Final Advanced Materials, basalt fibre fabrics are available untreated or with a clear water based Polyurethan (PU) coating. This tratement stabilises the fabric and reduces the mechanical irritations caused by the stiffness of loose filaments.

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%.
