Parameters of Ceramic Fiber Cotton
Ceramic thermal cotton is a high-temperature insulation material made from alumina silica fibers. These fibers are produced by melting high-purity alumina and silica at extremely high temperatures. The molten material is then spun into fine fibers, creating a lightweight and flexible cotton-like material. See its parameters.

Key Raw Materials in Ceramic Cotton
- Alumina (Al2O3): This content provides high-temperature resistance and stability.
- Silica (SiO2): This content enhances thermal insulation and flexibility.
- Zirconia (ZrO2): This is added for improved thermal shock resistance in some grades.
Advantages of Ceramic Fiber Cotton
- Excellent Thermal Insulation: Low thermal conductivity (as low as 0.03 W/m·K) ensures minimal heat loss, improving energy efficiency.
- Lightweight and Flexible: With a density of 96-128 kg/m³, it is easy to handle, cut, and install, reducing labor costs.
- High-Temperature Resistance: This feature shows an withstand temperatures up to 1260°C (2300°F), making it ideal for extreme heat applications.
- Thermal Shock Resistance:It performs well under rapid temperature changes, maintaining structural integrity.
- Chemical Stability: Resists corrosion from acids, alkalis, and other chemicals, ensuring long-lasting performance.
- Sound Absorption: Ceramic fiber bulk provides excellent soundproofing, making it suitable for noise reduction in industrial settings.
Applications of Ceramic Fiber Cotton
- Power Generation: Insulates boilers, turbines, and heat recovery systems, ensuring optimal performance.
- Petrochemical Industry: Provides insulation for reactors, pipelines, and storage tanks, reducing energy consumption.
- Automotive Industry: Used in exhaust systems and catalytic converters for thermal and acoustic insulation.
Global Case in Steel Industry
A steel manufacturer in Germany used Kerui’s ceramic fiber cotton to insulate their annealing furnace. The result was a 25% reduction in energy consumption and a 15% increase in furnace lifespan, thanks to the material’s excellent insulation properties.
