Ceramic Fiber Yarn, it is made from alumina-silica ceramic fiber, free of asbestos, can be used in different industrial applications under temperature up to 2300F(1260C) and has
excellent chemical stability and strong resistance to thermal shock and corrosion attack. Exceptions are hydrofluoric and phosphoric acids and concentrated alkalis. It also resists oxidation and
reduction, If wet by water or steam, thermal properties are completely restored upon drying. No water of hydration is present. It contains 15% organic carriers, which helps to establish physical
formation of Products. The cariers burn out at about 750F(400C). It also contains reinforcement insert materials of either Inconel wire or continuous fiberglass filament to increase handling strength
during installation and enhance fiber durability to rated temperture of 2000F(1093C) for inconel wire and 1200F(649C) for fiberglass filament
