Ceramic fiber paper is a lightweight, high-temperature resistant refractory material made from high-purity alumina silica ceramic fibers. Through a wet forming process similar to papermaking, these fibers are mixed with organic binders to form a uniform and soft sheet. Organic adhesives will burn off during the initial heating process, leaving behind a pure inorganic fiber structure.

Ceramic fiber paper has low shrinkage, good processing strength, and low thermal conductivity. It contains a small amount of organic adhesive used for processing, making it flexible while reducing exhaust gases and odors during use. Due to its controlled basis weight and thickness, our product has a highly uniform structure, ensuring uniform thermal conductivity and a clean and smooth surface, making it an ideal choice for gaskets or seals.
Ceramic fiber paper is completely asbestos free and aims to become an economical alternative to asbestos paper in most applications.

Technical Specifications

Why Choose Our Products?

• High Temperature Stability: Continuous service temperature typically ranges from 2300°F to 2732°F (1260°C to 1500°C), depending on the grade (standard, high-purity, or zirconia-reinforced).
• Low Thermal Conductivity: Exceptional insulating capability reduces heat loss and saves energy.
• Low Thermal Mass & Heat Storage: Its thin, low-density structure heats and cools rapidly, enabling faster thermal cycles.
• Excellent Thermal Shock Resistance: Resists spalling and cracking even under sudden, extreme temperature changes.
• Chemical Stability: Resistant to most corrosive agents (except hydrofluoric acid, phosphoric acid, and strong alkalis). Does not wet with molten aluminum.
• Mechanical Flexibility: Easy to cut, wrap, fold, or die-cut into complex shapes.
• Low Shrinkage: Maintains dimensional stability under high heat.
• Electrical Insulation: Provides good dielectric strength at elevated temperatures.
• Non-Wetting to Molten Metals: Particularly suitable for aluminum casting applications.
