Basalt Fibre Sleeves, up to 800 °C
Final Advanced Materials presents a range of products made of basalt fibre with extreme resistance. As a matter of fact, this high-temperature material offers properties that are far superior to glass fibre. Basalt fibre is also ecological when it comes to both manufacturing and recycling it.
Basalt fibre products can resist flame as well as chemicals and are very good acoustic and electrical insulators. As they remain functional with peak temperatures up to 800 °C and operating temperatures up to 700 °C, they are used for high-temperature applications. Moreover, they offer excellent thermal stability, mechanical and chemical resistance.
Basalt fibre sleeves are made from fibres with a diameter ranging from 8 to 16 µm. They are fireproof and produce neither smoke nor toxic gases. They are mainly used in the insulation of electrical cables and as thermal protection for pipes and exhausts in the automobile industry.
The basalt fibre sleeves proposed by Final Advanced Materials are available in sections ranging from 1.5 to 22 mm.
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.
