Ceramic Fiber Board
Rigid, Lightweight, Fireproof – Ideal for Furnaces, Kilns, and High-Temperature Equipment
Ceramic fiber board is a high-performance insulation product formed in a vacuum process using ceramic fibers and adhesives. It has a smooth surface with evenly distributed ceramic materials, providing excellent thermal insulation properties. Due to its low thermal conductivity and low heat storage, it does not expand when heated, helping to reduce energy costs and cycle times while protecting refractory surfaces from thermal shock and chemical erosion. With its combination of insulation, mechanical strength, and dimensional stability, ceramic fiber board is an ideal choice for rigid insulation applications in high-temperature industries.
🔥Extreme Heat Resistance: Withstands up to 1430°C (zirconia-enhanced grade).
🏋️High Strength: Compressive strength 1-5 MPa, ideal for load-bearing insulation.
❄️Superior Insulation: Thermal conductivity 0.08-0.15 W/m·K (800°C), reducing energy costs by 20-30%.
🛡️Rigid & Durable: Resists airflow erosion and mechanical impact (vs. fiber blankets).
🪶Lightweight: Density 200-400 kg/m³ (1/3 weight of traditional refractory bricks).
🧪Chemical Stability: Resists acid/alkali corrosion (except HF).
🌱Fireproof & Eco-Friendly: Non-combustible (ASTM E136), asbestos-free.
•High-temperature industrial equipment: kiln lining, thermal equipment insulation doors, burner lining plates.
•Specialized and civilian applications: fireproof building materials, household fireplaces and barbecue grills, laboratory high-temperature equipment.
• Ordinary :1100℃
• Standard:1260℃
• High purity type:1360℃
• Containing zirconium type:1430℃
A：Ceramic fiber board is used for high-temperature insulation in industrial furnaces, kilns, fireproof structures, and combustion chambers. It resists direct flame and thermal shock, making it ideal for applications in metallurgy, petrochemical, power generation, and more.
Q：Are you a ceramic fiber board manufacturer or a trader?
