E-Glass Fibre Sleeves, heat-resistant up to 700 °C
Since its patent in 1930, E-glass fibre is distinguished by its resistance to high temperatures and its excellent electrical insulating properties. This high-quality fibre ist rot-proof, resistant to the most common chemical agents and dimensionally stable, even in the event of substantial variations in humidity and temperature.
While E-glass filaments of diameter exceeding 9 μm can cause skin irritations, filaments with a diameter smaller than 3 μm are respirable and can build up in the respiratory system. For these reasons, E-glass fibre products supplied by Final Advanced Materials are manufactured using E-glass filaments with a diameter between 6 to 9 μm.
The high flexibility of E-glass sleeves facilitates the insertion of cables or pipes that need to be insulated. Moreover, these sleeves can withstand operating temperatures up to 550 °C and peak temperatures up to 700 °C. Therfore, they are used in the industry for the thermal protection and the electrical insulation of cables and pipings.
Final Advanced Materials provides E-glass sleeves in braided versions with an inner diameter ranging form 12 to 110 mm. A silicone coating is also available to improve the properties of the sleeves. 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.
