ceramic fiber blankets
Product Description
FZXT FERROALLOY SMELTING CO.,LTD
CERAMIC FIBER BLANKET
There are 5 standard grades of ceramic fiber blankets, 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, these blankets are produced from high strength spun ceramic fiber and needled to provide exceptional handling strength. These blankets are completely inorganic and are available in a variety of densities, thickness, widths, and temperature ratings:
