Ceramic fiber paper is a lightweight, flexible high-temperature insulation material manufactured from high-purity silica-alumina fibers. Its exceptional heat resistance and thermal insulation properties make it indispensable across traditional heavy industries such as steel and petrochemicals, while its strategic importance continues to grow in cutting-edge sectors including new energy and semiconductors.
Driven by evolving application demands and material technology innovations, ceramic fiber paper has evolved from a basic insulation material into a high-performance, composite, and environmentally friendly solution. It is widely deployed in industrial high-temperature environments and kiln furnaces where reliable thermal management is critical.
