KEIRBY PRODUCT DATA SHEET
Twisted or Stranded Ropes
Twisted ropes are manufactured from high performance ceramic fibre yarns, re-inforced with either a wire or glass filament. Yarns are produced on traditional textile machinery by carding high purity 1260°C grade ceramic fibres with a percentage of cellulose fibre to assist in the processing.
The yarns are then spun and combined with the relevant re-inforcing media to improve the tensile strength at extended temperatures.
The organic content will burn off at temperatures above 200°C without affecting the properties of the ceramic fibre, however, adequate ventilation should be provided during this initial firing. Where tensile strength is important the temperature limitations of the re-inforcing media should be considered.
Ceramic fibre are suitable for use at temperatures up to 1260°C dependant on application.
Resistant to most chemicals except phosphoric acid, hydrofluoric acid and strong alkalis.
Are non combustible.
Have a low thermal conductivity.
Resistant to thermal shock.
Temp Limitations: >E= glass filament suitable for temperatures up to 550°C.
Nickel chrome alloy wire 601 suitable for temperatures up to 1091°C.
Chrome steel wire suitable for temperatures up to 1000°C.
Typical Applications: Bulb
material for tadpole seal, boiler door seals, launder section seals.
