Ceramic Fiber
Cloth is a compression packing for very high temperature
duties. It is manufactured from an exceptionally stable
fibre material that is soft, non-irritating,
non-hazardous & is not limited by World Health
Organisation or European Union restrictions.
These heat resistant fibres are produced using
advanced chemical fibre technology. They are spun
into a flexible yarn in the UK, together with a low
percentage of glass fibre and Inconel wire
reinforcement.
Ceramic Fiber yarn, Rope, Cloth contains no organic
agents or processing additives. It therefore retains its
physical and chemical properties at very high
temperatures and does not decompose into hazardous
substances, as happens with many normal ceramics.
Typical Applications :
Compression packing of Ceramic Fiber Product Hi-Temp are
recommended for very high temperature static sealing
duties or slow rotary applications. It replaces ceramic
yarn packing and radiation seals on BOS plant, and
ceramic packings and vessel lid seals on secondary
steelmaking plant.
Other examples include door seals for annealing
furnaces at steelworks, kiln packings, protective
surfaces on pottery kiln cars, and stem gland
sealing on valves handling very high temperature
gases.
Ceramic Fiber Textile resist Hi-Temp include braided
insulation sleeves, webbing tapes, ladder tapes, twisted
ropes, lagging ropes, blankets and paper, and woven
cloth. These are used for thermal insulation and heat
resistant duties where flexibility and resilience are
required.
Prime
features :
• Non-hazardous heat resistant fibre construction
• 1000°C for constant duties, with excursions to 1100°C
• Competitively priced alternative to normal ceramic
fibre packings
• Far better value for money than other non-hazardous
high temperature materials, such as those made of pure
silica fibre
• Good chemical compatibility
Health & Safety considerations :
Average diameter of the mineral fibre used in Ceramic
Fiber product Hi-Temp is 9µm which is considered
non-hazardous tohealth. No
protection for breathing, eye, hand or body is required
by the World Health Organisation or European Union
during the product's normal storage, handling and use.
Please note that normal ceramic fibres, as often
used in the manufacture of very high temperature
compression packings, are around 3µm diameter. These
much finer fibres are now considered
hazardous to health, with WHO and EU
restrictions applied to the products that contain
them.
