Aramid Fibre Fabric, up to 400 °C
The word 'aramid' is a contraction of 'aromatic polyamide'. The chemical name is para phenylene terephthalamide or PPD-T. Created in the 1960’s, aramid fibres consist of yellow filaments of about ten microns in diameter, assembled into threads.
Woven in plain weave, 100 % para-aramid fabrics (Kevlar®) have excellent thermal characteristics. In addition to their good insulating properties, they can reach a peak temperature of 500 °C and a continuous temperature of 350 °C. In addition to this, they have excellent resistance to cuts, abrasion, tearing and acids, as well as excellent mechanical properties. Available in different versions (aluminised, fleece, etc.), they are particularly suitable for the manufacture of protective clothing and thermal insulation.
100 % para-aramid (Kevlar®) fabrics always include a cross-twill woven version (two single twills in different directions). Particularly resistant to high temperatures up to 450 °C and cuts, it is mainly used to reinforce protective clothing. Coated versions (silicone, aluminium, flame retardant, etc.) are available.
70 % Panox® / 30 % Kevlar® twill is a good alternative to 100 % aramid fabrics. The fiber is an oxidized, thermally stable, polyacrylonitrile fiber. This fiber mixture allows the textile to withstand up to a temperature of 400 °C continuously (maximal temperature 600 °C). It is particularly suitable for use against sparks and projected materials. On the other hand, its mechanical properties are inferior to a 100 % para- aramid fabric. It is mainly used in the manufacture of seats for the rail and air industries. An aluminium version is also available.

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%.
