E-Glass Sleeves, up to 700 °C
Since its patent in 1930, E-glass fibre was used in the industry for its resistance to high temperatures and its great electrical insulation properties. This rot-proof fibre remains dimensionally stable, even with strong variations in humidity and temperature and can withstand the main chemical agents.
E-glass filaments with a diameter bigger than 9 μm can cause to skin irritation. However, filaments smaller than 3 μm are respirable and can lead to build-up in the respiratory system. To prevent these risks, our E-glass fibre sleeves are manufactured using filaments with a diameter ranging from 6 to 9 μm.
E-glass fibre sleeves are very flexible, which facilitates the insertion of the cables and pipes that need to be insulated. They are ideal for the electrical insulation of wirings, electrical cables and piping. Moreover, these products can withstand peak temperatures up to 700 °C and operating temperatures up to 550 °C.
The sleeves are available in an inner diameter ranging from 12 to 110 mm in braided versions. A silicone-coated version is also available on request, for the improvement of some of the product's properties. For more information regarding the availability, refer to the technical data sheet.

FAQs that can help you in this category
Sleeves are tubes, usually flexible, designed to protect cables or electrical components from electricity, heat, and mechanical forces or impacts. Final Advanced Materials offers sleeves capable of withstanding temperatures up to 1,300°C in continuous service. For protection against radiant heat, Final Advanced Materials manufactures custom laminated sleeves using thin aluminium foils. This construction reflects up to 95% of radiation exchanges, thereby protecting cables from exposure to excessively high temperatures.
Few materials are suitable for exposure to contact temperatures over 1,200°C in continuous service, without radiation. Silica fibres, for example, are not stable during prolonged exposure. If you are seeking electrical insulation without the risk of deformation at such temperatures, ceramic fibre is the only viable solution. Other materials may also be suitable, depending on the duration and frequency of exposure, such as materials made of coated or uncoated glass fibres, basalt fibres, or silica fibres. However, these parts will need to be replaced regularly, and the replacement frequency will depend on the usage.
The primary downside of textile products is their low resistance to abrasion. To counteract this downside, Final Advanced Materials offers numerous treatments (silicone, PTFE) which improve this resistance. It should however be noted that these treatments can modify the sleeve’s behaviour when exposed to temperature.
For optimal thermal insulation, whether for operator protection or for reduced heat loss, it is important to select the correct insulating material and thickness. Final Advanced Materials has the necessary teams and skills to simulate these thermal exchanges and can determine not only the appropriate material but also the required thickness.
