Ceramic Fibre

High temperature monofilament ceramic fibres.

Final Advanced Materials offers a full range of products in various forms of ceramic fibre: tapes, threads, sleeves, fabrics, etc.

What are Ceramic Fibres?

Final Advanced Materials can supply an innovative continuous polycrystalline ceramic fibre. The metallic oxides at the heart of its composition ensure that the processing of this fibre into ceramic textiles is particularly simple. It is mainly used in the aerospace, automotive, electrical and petrochemical industries.

This fibre also has a very low elongation and shrinkage rate thanks to its application temperature. As a result, manufacture is dimensionally stable. This continuous fibre demonstrates a mechanical and thermal performance that fibrous materials do not achieve, such as aramid, silica or glass fibres. In addition, this fibre has excellent chemical resistance, excellent dielectric strength, low thermal conductivity, good thermal shock resistance and low porosity.

General Characteristics of Ceramic Fibres

Moisture Uptake

Moisture absorption of monofilament ceramic fibres is extremely low. Thanks to their nonporous surface, the fibres are able to retain a maximum of 0.08 % of their weight in water.

Thermal Properties

Monofilament ceramic fibres have low conductivity and excellent resistance to high temperatures, making them an incomparable thermal insulator.

Ceramic Fibres Products

Threads

Ceramic threads are primarily designed for thermal, electrical and mechanical applications subjected to extreme conditions. Composed mainly of Al2O3 at different percentages, the 080-0600 strips withstand continuous temperatures up to 1,370 °C. They are used for the manufacture of fire safety equipment and electrical or chemical insulators.

Sleeves

Ceramic sleeves type 080-0500 can withstand operating temperatures up to 1,370 °C. They are particularly suitable for the insulation and protection of cables, tubes, pipes and thermocouples. They can also be used as insulation seals.

Tapes

The 080-0700 ceramic tapes are resistant to operating temperatures up to 1,100 °C. They are particularly suitable for the insulation and protection of cables, tubes and pipes and to strengthen packaged products. A Heat Cleaned coated version is available to limit irritations for customized applications as well as flying fibres and the amount of smoke generated during exposure to high temperatures.

Fabrics

080-0300 and 080-0400 ceramic fabrics are resistant to continuous operating temperatures of 1,100 °C and 1,370 °C, respectively. They are mainly used in the industry as a heat shield or fire barrier. A Heat Cleaned coated version is available to limit irritations for customized applications as well as flying fibres and the amount of smoke generated during exposure to high temperatures.
