Biosoluble Fibre Sleeves, heat-resistant up to 1,150 °C
Biosoluble fibres are guaranteed asbestos and ceramic fibre-free. To eliminate the health risks associated with exposure to rock fibres or ceramic fibres for insulation, their chemical composition has been adapted. These fibres dissolve in bodily fluids such as those found in the pulmonary alveoli. They are less biopersistent, meaning they are eliminated more quickly by the body while maintaining their excellent fire protection and thermal insulation properties.
Biosoluble fibre sleeves offer great thermal resistivity and are good insulators. They are therefore used in the industry for the insulation of exhausts, pipes and electrical cables.
Final Advanced Materials provides biosoluble fibre sleeves in inner diameter ranging from 8 to 80 mm. A reinforcing with E-glass fibre or heat-resistant steel is also available to obtain better mechanical properties. Depending on the reinforcing used, the sleeves can resist peak temperatures up to 1,150 °C and operating temperatures up to 1,050 °C.

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.
