Refractory Ceramic Fibre Packing (Soft Lagging Core) (Wire Reinforced): our soft ceramic packing is a seal and insulating rope, made by over braiding mechanically resistant wire reinforced ceramic yarns around a soft lagging core. The overbraid covers the core 100% (full coverage). Its soft lagging core of the packing consists of blown ceramic fibres resistant to very high temperatures.
The combination of wire reinforced ceramic yarn and ceramic fibre filler makes the soft ceramic packing particularly suitable for static sealing applications. The ceramic fibre insulation is rated to 1260°C in situ with a rating of 1000°C for the wire reinforcement.
Please note that our packing is normally supplied in loomstate form. In the manufacture of ceramic yarn a certain small percentage of 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.
