E-glass fibre fabrics, up to 700 °C
Since 1930, E-glass fibre has been used in the industry for its great electrical insulation properties. This rot-proof fibre can resist high temperatures as well as the main chemical agents and remains dimensionally stable, even with strong variations in humidity and temperature.
E-glass fibre fabrics are particularly attractive for their electrical properties, their thermal resistivity and their chemical resistance. Moreover, they can withstand peak temperatures up to 700 °C and present noteworthy mechanical properties. In the industry, E-glass fibre fabrics have many applications, like the manufacture of gaskets, compensators, thermal reflectors or protective clothing.
At Final Advanced Materials, E-glass fibre fabrics are manufactured using E-glass filaments with a diameter ranging from 6 to 9 µm. This composition prevents the risks of build-up in the respiratory system and skin irritation.
Our E-glass fibre fabrics are available untreated or with a vermiculite, silicone or aluminised finish. These coatings enhance some of the fabrics’ properties, like the resistance to high temperatures or abrasion.
For more information regarding the availability, refer to the technical data sheet.
E-glass fibre fabric with a silicone coating
A silicone coating enhances the performance of E-glass fibre. This polymer derived from silicon improves the resistance of glass fibre against weather conditions, aqueous solutions, weak acids and bases. A textile coated with silicone can withstand temperatures up to 250 °C. For more information regarding the technical properties of the treated fabric, refer to the technical data sheet.
E-glass fibre fabric with a vermiculite coating
A vermiculite coating improves the performance of E-glass fibre. This natural mineral enhances its resistance to abrasion and its ability to withstand high temperatures. An E-glass fibre fabric coated with vermiculite can be used for the manufacture of gaskets, compensators or protective clothing. For more information regarding the technical properties of the treated fabric, refer to the technical data sheet.
E-glass fibre fabric with an aluminised side
When coated on one or both sides of an E-glass fibre fabric, aluminium improves the performance of the fibre. This treatment enhances its resistance to radiant heat up to 1,650 °C. Aluminium also boosts the fabric’s resistance to flame and splashes of molten metal. For more information regarding the technical properties of the treated fabric, 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%.
