- 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 low organic content to minimize fume emission.
- 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
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.
