Ceramic Fiber Paper – High-Temperature Insulation up to 1430°C with Low Thermal Conductivity
Engineered for precision and reliability, our Ceramic Fiber Paper is a versatile, lightweight refractory sheet produced from a uniform blend of high-purity alumina-silica fibers. With a controlled, smooth surface and consistent thickness, it delivers predictable thermal and electrical insulation performance. Formulated with a minimal organic binder for flexibility during installation and low off-gassing during use, it serves as a high-performance, cost-effective, and safe asbestos-free replacement across numerous industrial applications.
Available in four grades -- Standard, High Pure, High Aluminium, and Zirconium -- our ceramic fiber paper covers maximum service temperatures from 1050°C to 1430°C. Each grade is produced under strict quality control protocols, ensuring consistent chemical composition, uniform density, and reliable performance in continuous high-temperature environments. The material is completely asbestos-free and designed with low organic content (≤5%) to minimize fume emission during first heat-up.

Why Choose Our Products?
Exceptional Handling and Machinability - Easily cut, wrapped, or die-cut into complex gaskets and shapes without fraying, thanks to its good flexibility and tensile strength. The uniform structure ensures clean edges and consistent performance in precision applications.
High-Temperature Integrity - Maintains excellent dimensional stability and chemical resistance under continuous exposure, with grades suitable for up to 1430°C. Low shrinkage rates ensure the paper retains its shape and sealing properties throughout its service life.
Electrical and Acoustical Insulation - Provides good dielectric strength and sound absorption properties for multi-functional use in electrical equipment and noise-sensitive applications.
Safe and Compliant - Completely free of asbestos and designed with a low organic content (≤5%) to minimize fume emission during initial heat-up. Meets modern safety and environmental standards for industrial workplaces.
Primary Applications
Gasketing and Sealing - Die-cut gaskets for coke oven doors, blast furnace hot air systems, aluminum furnaces, heat treat equipment, and other high-temperature sealing applications requiring a compressible, heat-resistant barrier.
Backup Insulation and Wrap - Layer behind brickwork, insulation wrap for tundishes, ladles, hot metal cars, and SEN (Submerged Entry Nozzle) insulation in steelmaking and foundry operations.
Thermal Barriers and Protection - Heat shield for welding and brazing, mould wrap for controlled cooling, expansion joint packing, and other thermal protection applications.
Frequently Asked Questions (FAQ)
Q1: How do I select the right grade for my application?
The selection depends on your maximum operating temperature, chemical environment, and required purity. Standard grade (1050°C) is suitable for general-purpose insulation and gasketing. High Pure grade (1150°C) offers higher purity for applications sensitive to impurities. High Aluminium grade (1260°C) provides enhanced chemical resistance and higher temperature capability. Zirconium grade (1430°C) is recommended for the most demanding ultra-high-temperature applications. Please provide your design specifications for a tailored recommendation.
Q2: What is the organic content and why does it matter?
Our ceramic fiber paper contains ≤5% organic binder, which provides flexibility during installation. During the first heat-up, this binder burns off cleanly with minimal fume emission. The low organic content ensures that the paper maintains its structural integrity and thermal performance after binder burnout, with no harmful residues affecting the application.
Q3: Can this paper be die-cut into custom gaskets?
Yes. Our ceramic fiber paper is specifically designed for excellent machinability. It can be easily die-cut, laser-cut, or hand-cut into complex gaskets and shapes without fraying. The uniform density and consistent thickness ensure clean edges and reliable sealing performance in precision applications.
