CeramSource offers 3 standard grades of spun ceramic fiber blanket, all of which are lightweight and thermally efficient, resulting in a material that possesses the advantages of low heat storage and complete resistance to thermal shock. Used in a variety of heat processing applications, the ceramic fiber blanket is produced from high strength spun ceramic fibers and is needled to provide exceptional handling strength. The ceramic fiber blanket is completely inorganic and is available in a variety of densities, thicknesses, widths and temperature ratings:
Commercial grade: service temperature 1800°F High-Purity grade: service temperature 2300 °F Zirconia grade: service temperature 2600 °F Standard Densities: 6, 8 Ibs./cu. ft. (96, 128 kg/m3) Standard Thicknesses: 1/2", 1", 1-1/2",2" Standard Widths: 24" and 48" Standard Packaging: Cartons or bags
Note: Other densities available per special request
