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.

• Good flexibility and toughness with excellent resistance to avulsion
• Easy to wrap, shape, or cut — lightweight and simple to work with
• Excellent chemical stability and machining properties
• Superior thermal shock resistance
• Good uniformity and smooth surface appearance
• Good dielectric strength and sound insulation performance
• Low thermal conductivity and low heat storage
• Excellent corrosion resistance

• Industrial Furnace Sealing: Provides high-temperature sealing for furnace doors and observation ports, preventing heat loss and gas leakage.
• Expansion Joint Fillers: Fills expansion joints in furnace linings to absorb thermal stress and prevent structural cracking.
• Automotive Exhaust Systems: Insulates exhaust pipes and mufflers to reduce surface temperatures and absorb noise.
• Appliances and Electronics: Electrically insulates heating elements in ovens and protects sensitive electronic components from heat.
• Backup Insulation Linings: Serves as lightweight backup insulation behind refractory bricks in steel ladles and industrial kilns.
• Glass and Ceramic Kilns: Acts as a release material for glass fusing and protects kiln shelves from glaze drips.
• High-Temperature Filtration: Filters hot gases or molten metals and acts as a welding barrier to block sparks.
• Metal Casting and Foundry: Insulates hot tops and risers while acting as a non-wetting anti-sintering agent for molten metal.
