Ceramic fiber is a fibrous lightweight refractory material, which is mainly made of aluminum silicate, silicon dioxide, alumina, zirconium oxide and other materials, and is suitable for various high-temperature, high-pressure, and non-wear environments.
(1) Excellent thermal insulation performance
(2) Excellent thermal stability: the fiber has good resistance to devitrification
(3) Low heat storage
(4) Tough, elastic and strong blanket,
(5) Not easy to tear before and after heating
(6) Thermal shock resistance
(7) Good acoustic properties
(1) Power generation, especially heat recovery boiler pipe insulation
(2) Industrial and commercial chimney insulation
(3) Furnace, boiler and heater linings
(4) Pipe wrapping
(5) Backup linings for kilns and furnaces
(6) Consumer products
(7) Heat storage insulation
