Hight-temperature thermal insulation fibre

High-temperature thermal insulation fibre is used as thermal insulation for boilers, stress-relief welds, pipeline networks, glass-melting furnace arches in the nuclear industry, gas and steam turbines, various operator process cabins on rolling mills, cabinets, assemblies, etc.; lining of bell-type furnaces, industrial kilns for drying and firing, chimneys, air ducts, smoke stacks, walls and arches of tunnel and ring kilns in the ceramic industry, covers of shaft furnaces, walls and arches of heating, thermal, annealing and hardening furnaces, covers of low-temperature stands for heating tundishes, covers of steel-teeming ladles, smelting furnaces, as a sealant for furnace doors, thermal barriers in the automotive industry; filler for expansion joints in masonry; and is also a thermal insulation layer in furnace units.
