1260C thermal insulation for ceramic fiber gaskets

Refractory aluminosilicate thermal insulation gaskets ceramic fiber gaskets Temp.:1260C Density:200kg/m3 Thickness:1-6mm

JIUQIANG Refractory aluminium silicate thermal insulation gaskets

ceramic fiber paper pads is manufactured from high-grade ceramic fiber with low slag ball content, and formed into excellent flexible sheet through unique beating, deslagging, slurry-compounding, long net forming, vacuum water removal, drying, cutting and rolling processes.

   It is featured with high temperature resistance and heat insulation and high anti-melt capability, very low thermal conductivity, chemical corrosion resistance and thermal shock stability.    So the paper can be widely used in building, glass industry for teeming pads separation. It provides maximum heat resistance and thermal insulation in limited space.

Typical Application

Die cut gaskets between castings in coke oven doors, blast furnace hot air piping, aluminium heat treating furnace, tuyeres and heat treat furnaces. Backup for brick and monolithic refractories in blast furnace stoves, piping, tundish, ladle, hot metal cars, trough etc. Mould wrapping for controlled cooling SEN isulation wraping Shield for welding & brazing operation Rotary klin back-up insulation Ladle & tundish insulation Asbestos paper replacement Hot top linings Thermal and electrical insulation.
