Textile rope Refractory Ceramic Fibre Packing (Graphite Impregnated)

ceramic fiber

Refractory Ceramic Fibre Packing (Graphite Impregnated): manufactured from high performance refractory ceramic fibre yarns, reinforced with either glass or wire filament to produce a round rope section. Our ceramic 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 processing. The yarns are spun and combined with the relevant re-enforcing media to improve the tensile strength at extended temperatures. Its organic content burns off at temperatures above 200°C without affecting the ceramic fibre; adequate ventilation is needed during this initial firing. Where tensile strength matters, the temperature limitations of the re-enforcing media should be considered. It is suitable for temperatures up to 1260°C dependant on application. Also resistant to most chemicals except phosphoric acid, hydrofluoric acid and strong alkalis. The packing is non-combustible, has low thermal conductivity, and is resistant to thermal shock. Its open overbraid of stainless steel enhances the abrasion resistance and prolongs the life of the seal considerably. The E Glass filament reinforcement is rated up to 550°C. The wire reinforcement is rated up to 1000°C, Glass reinforcement up to 650°C. A graphite aqueous mineral dispersion has been added to improve abrasion resistance and aesthetics. Our packing is normally supplied in loomstate form. In the manufacture of ceramic yarn, some organic binder is used to aid spinning. This can sometimes cause "flashing" at high temperatures.
