Ceramic fiber paper, as a key insulation material for traditional high-temperature industries such as steel and petrochemicals, has seen its development transforming from a basic insulation material to a high-performance, composite, and environmentally friendly one under the joint promotion of upgraded demand in application fields and material technology innovations. Its strategic importance is constantly emerging in cutting-edge industries such as new energy and semiconductors.
Ceramic fiber paper is a lightweight and flexible high-temperature insulation material made of high-purity silicon dioxide-aluminum fiber. Due to its high temperature resistance and insulation properties, it is widely used in industrial high-temperature and kiln furnaces.
