High Temp 1430°C Refractory Ceramic Fiber Paper Thermal Insulation Low Conductivity
Thermal Insulation Ceramic Fiber Paper High Temp 1430°C Low Conductivity
Product Overview:
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.

Key Properties & Advantages:
- Exceptional Handling & Machinability: Easily cut, wrapped, or die-cut into complex gaskets and shapes without fraying, thanks to its good flexibility and tensile strength.
- Superior Thermal Management: Offers very low thermal conductivity and low heat storage, providing efficient insulation and rapid thermal cycling capability.
- High-Temperature Integrity: Maintains excellent dimensional stability and chemical resistance under continuous exposure, with grades suitable for up to 1430°C.
- Electrical & Acoustical Insulation: Provides good dielectric strength and sound absorption properties for multi-functional use.
- Safe & Compliant: Completely free of asbestos and designed with a low organic content to minimize fume emission.
Diverse Industrial Applications:
- Gasketing & Sealing: Die-cut gaskets for coke oven doors, blast furnace hot air systems, aluminum furnaces, and heat treat equipment.
- Backup Insulation & Wrap: Layer behind brickwork, insulation wrap for tundishes, ladles, hot metal cars, and SEN (Submerged Entry Nozzle) insulation.
- Thermal Barriers & Protection: Heat shield for welding/brazing, mould wrap for controlled cooling, expansion joint packing.
- Specialized Liners & Components: Induction coil liner, mould liner, silencer interleaf, hot top linings, and as a direct asbestos paper replacement.
Engineered for Performance & Safety:
More than just paper, this is a precision-engineered thermal management material. Its uniform structure ensures consistent performance, while its asbestos-free composition and low fume profile address modern safety and environmental standards, making it the responsible choice for upgrading legacy installations.
