KEIRBY PRODUCT DATA SHEET

High & Low Density Cabled Rope

Construction
Cabled ropes are manufactured from high performance ceramic fibre yarns (High Density) or twisted Card Sliver (Low Density), re-inforced with either a wire or glass filament. Sliver and 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 spun and combined with the relevant re-inforcing media to improve the tensile strength at extended temperatures. The yarn of sliver is first assembled and twisted and balanced to produce a cabled rope.

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.

Properties
Ceramic fibres 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.

Re-inforcements
Temp limitations: >E= glass filament suitable for temperatures up to 550°C.
Nickel chrome alloy wire 601 suitable for temperatures up to 1091°C.
