China ISO9001 Manufacture of Bio Soluble Fiber Board 1260c

NRBIO300 is a uniformly bonded combination of NON-RCF alkaline earth silicate fiber insulation board. Exhibiting superior machineabilty - many detailed custom shapes can be made from it. NRBIO300 is suitable for use as a substitute for insulation containing refractory ceramic fiber materials in applications with temperatures to 1260°C (2300°F).

Soluble fiber boards are designed for applications which require high strength and rigidity with high temperature and excellent insulation properties.

Temperature: Up to +1260°C.
Key features: Security and environmental protection;
Low thermal conductivity;
Low shot content;
Resistance to the corrosion of molten aluminum;
Low loss of heating storage;
Good capacity of thermal shock resistance.
Applications: Kiln linings, furnace linings, gaskets & seals, fire protection, glass tank insulation, expansion joints, hot gas duct linings, refractory backup insulation.
