Biosoluble fibre

Final Advanced Materials has a wide range of biosoluble fibre products available: packings, twisted ropes, braided ropes, felts, fabrics, paper, sleeves, tapes, etc.

What is Biosoluble Fibre ?

Biosoluble fibres are guaranteed asbestos and ceramic fibre-free. In order to eliminate the health risks associated with exposure to ceramic fibres or rock 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 thermal insulation and fire protection qualities. Our biosoluble fibre products are reinforced with glass or refractory steel which enhances their thermal resistance up to 650 °C (E-glass) and 1,050 °C (refractory steel).

Applications of Biosoluble Fibre

• Insulation for pipes and exhausts
• Electrical insulation
• Metal work

Comparative Table

Product Range of Biosoluble Fibre

Our products in biosoluble fibre can adapt to different applications to suit all requirements:

Tapes

Biosoluble fibre strips are available in 2, 3 and 5 mm thicknesses with widths of 10 to 200 mm. Adhesive strips and strips with bolt holes are also available.

Packings

Produced with an E fibreglass sleeves, the packing has excellent flexibility while maintaining good mechanical strength. The core consists of 100 % biosoluble fibres. Sleeves are available in diameters from 12 to 80 mm and can reach a peak temperature of 600 °C.

Twisted Ropes

Biosoluble fibre twisted ropes are reinforced, either with E-glass fibre or with refractory steel (Inconel®):

• Glass fibre reinforcement is more cost-effective, and provides the benefit of not being electrically conductive;
• Refractory steel reinforcement increases the strength of the high-temperature braided cord, and improves its physical properties, whilst preserving its initial flexibility. These twisted ropes are available in diameters ranging from 5 to 60 mm.

Braided Ropes

Alike twisted ropes, biosoluble fibre braided ropes can be reinforced with refractory steel or fiberglass and benefit from the same advantages. The biosoluble braided ropes are available in diameters ranging from 5 to 60 mm, in square, rectangular or round sections.

Bulk fibre

The product consists of a mass of randomly orientated, long, fluffy, resistant fibres. It has excellent thermal stability and retains its flexible fibrous structure up to a temperature of 1,000 °C. It contains no binders and emits no smoke or odor when first heated. The fibres are insensitive to thermal shock and absorb very little energy when heated. Biosoluble bulk fibre is available lubricated for use when filling or as expansion joints. The non-lubricated version is particularly useful for vacuum forming. The fibres are available in short, medium, long and extra-long sizes. The level of thermal conductivity depends on the degree of compression during installation.

Sleeves

Our sleeves are available in diameters of 15 to 60 mm. They are sold in 25 m rolls.

Felts

Biosoluble fibre felts are obtained from long fibres of alkaline earth silicate. Their high-temperature insulation performance is remarkable. With high thermal stability, they retain a flexible fibrous structure up to a temperature of 1,200 ° C. Felts contain no binders or lubricants and emit no smoke or odor when heated. Biosoluble fibre felts are flexible and easy to cut or install. They are available laminated with an aluminium film to improve the thermal properties of the sheets.

Papers

Made from alkaline earth silicate wool, biosoluble paper has an extremely uniform structure. Resistant to continuous operating temperatures up to 1,260 °C, this product has low thermal conductivity and high temperature stability as well as being light, smooth, flexible and easy to handle. These exceptional properties come from the careful selection of specific organic binders combined with advanced manufacturing processes. Our papers are available in thicknesses from 1 to 6 mm and a width of 610 mm. Sold in whole rolls, we also offer customized cuts. Other dimensions are available on request.

Fabrics

Biosoluble fibre fabrics are available in 2 and 3 mm thicknesses. During production, they are heat-treated to limit flying fibres and dust.
