Refractory Ceramic Fibre Twisted Yarn (Rope): our Ceramic twisted yarn is made with 80% ceramic fibres and 20% organic fibres. These organic fibres burn off at low temperatures, without affecting the characteristics of the ceramic fibre.
Ceramic twisted yarn is an excellent and pliable sealing material. The ceramic fibre insulation is rated to 1260°C in situ, its wire reinforcement is rated to 1000°C, and the glass reinforcement is rated to 550°C.
Our rope 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.
