Biosoluble Fibre Felt, up to 1 200 °C
Biosoluble fibres felts’ composition excludes all carcinogenic classification as per Q in directive 97/69 EC, unlike pure silica and silicate fibres. Biosoluble fibres felts are an ideal solution to replace ceramic fibres. Biosoluble 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 thermal insulation and fire protection qualities.
Biosoluble fibre felts are obtained from long fibres of alkaline earth silicate. With high thermal stability, they retain a flexible fibrous structure up to a temperature of 1,200 °C. Their high-temperature insulation performance is remarkable.
This range of product contains no binders or lubricants and emits no smoke or odor when heated. Biosoluble fibre felts are flexible and easy to cut or install. Biosoluble fibre blankets are available laminated with an aluminum film to improve the thermal properties of the sheets.
Applications of Biosoluble Felt
- Chimney, furnace and pipe insulation
- Heating and furnace lining
- Heat shield
- Component in the manufacture of thermal protection

FAQs that can help you in this category
Felts made from carbon/graphite fibre are excellent at withstanding high temperatures, and are used up to 3,000°C. These felts are stable up to 2,000°C, but only in an inert, oxygen-free environment. Otherwise, they oxidise above 300°C. Unlike carbon/graphite felts, zirconia felts are resistant to temperatures up to 2,000°C, even in the presence of oxygen in the environment.
Final Advanced Materials' biosoluble fibre felts are a safe alternative to replace asbestos-based insulation or other refractory fibres. These fibres have low biopersistence, meaning the body can eliminate any inhaled fibre rapidly and naturally. These felts have a low thermal conductivity and a temperature resistance of up to 1,400°C, and are used primarily as oven coatings, but also as a customisable local thermal insulation.
The only felts capable of withstanding a continuous exposure to temperatures exceeding 1,500°C are ceramic (Al2O3), zirconia (ZrO2) or graphite fibre-based felts. Each felt has specific constraints: graphite felts can only be used in an inert atmosphere or in a vacuum, while zirconia felts have poor mechanical properties, and ceramic fibre felts can only resist temperatures up to 1,650°C.
The other felt families (glass, silica, biosoluble, RCF, basalt, etc.) cannot withstand a continuous exposure to more than 1,260°C.
The material has a thermal conductivity of 0.06 W/m·K at 200°C, and 0.30 W/m·K at 1,000°C. It is substantially lower than that of conventional refractory materials (often between 1 and 2 W/m·K at these temperatures). The felts offered by Final Advanced Materials are available in several densities, ranging from 64 to 160 kg/m3. The higher the density, the lower the conductivity which can go as low as 0.20 W/m·K at 1,000°C.
