Textile rope Refractory Ceramic Fibre Packing (Wire Reinforced)

ceramic fiber

Refractory Ceramic Fibre Packing (Wire Reinforced): manufactured from high performance refractory ceramic fibre yarns reinforced with wire filament to produce a round or square rope section. 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. They are spun and combined with the relevant re-enforcing media to improve the tensile strength at extended temperatures. The organic content will burn off at temperatures above 200°C not affecting ceramic fibre. Adequate ventilation should be provided 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 dependent on application, resistant to most chemicals except phosphoric acid, hydrofluoric acid and strong alkalis. It is non-combustible, has low thermal conductivity, and is resistant to thermal shock. The ceramic fibre insulation is rated to 1260°C in situ. Its wire reinforcement, rated to 1000°C. Packings are also available in rectangular sections. Our packing is normally supplied in loomstate form. Ceramic yarn has an organic binder is used to aid spinning. This can sometimes cause "flashing" at high temperatures. This can be avoided if the product is heat cleaned prior to use or if the organic impurities in the product can be allowed to burn off in situ on application for the initial period. In light of health and safety concerns for refractory ceramic fibre we strongly urge our customers to consider our S-TEX Silica, Belcotex, HT Modified Glass or Bio Soluble alternatives.
