Ceramic Fibre Braided Packing
Construction:
Saveguard Braided packings are manufactured from high performance C-Tex ceramic fibre yarns re-inforced with either a wire or glass filament. Braids are available in round or square section and with a soft or firm core. C-Tex yarns are produced on traditional textile machinery by carding high purity 1260 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 organic content will burn off at temperatures above 200 oC 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.
