Ceramic fiber yarn

It is made from alumina-silica ceramic fiber, free of asbestos, can be used in different industrial applications under temperatures up to 2300 °F (1260 °C) 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 carriers burn out at about 750 °F (400 °C). 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 temperatures of 2000 °F (1093 °C) for Inconel wire and 1200 °F (649 °C) for fiberglass filament.
Size: 1-5plies
Tex: 500, 525, 630, 780, 830, 1000, 2250 etc.
Application:It is used as heat insulation materials in thermal installations and heat conducting systems, Also can be extensively made into all kinds of ceramic fiber textiles and an excellent substitute for asbestos.
