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

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.
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.
