Application of Ceramic Fiber Paper

Ceramic fiber paper is widely used for high-temperature furnaces insulation and fire prevention. Because of its excellent high-temperature resistance and working temperature up to 1600 ℃, it has been widely used in industries such as steel, aluminum, and glass. Ceramic fiber paper is applied to various industrial furnaces, ladle, and immersion nozzle high-temperature insulation, industrial electric furnace  insulation, furnace doors and furnace expansion joint sealing materials. What is more, ceramic fiber paper can make high-temperature filters and sealing pads, which has provided a guarantee for industrial production.
