Hitech thermal refractory ceramic fiber blanket for fire resistance
1. Description
Ceramic fiber blanket is made by special ceramic long-fiber, which is produced by melting very pure raw materials and needling in double surface.Ceramic fiber blanket also named aluminum silicate fiber blanket, because their main component is aluminum. It’s a new type of fire-resisting and heat-insulating materials with white color and accurate dimension.
Ceramic fiber blanket is also called Aluminum silicate ceramic fiber blanket.
Aluminum silicate ceramic fiber blanket offers 5 standard grades of spun ceramic fiber blanket,it is completely inorganic and is available in a variety of densities, thicknesses, widths and temperature ratings, 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.
Ceramic fiber blanket does not contain any adhesive to ensure their stable performance in high temperature or low temperature environment.
Their Classification Temperature: 1050-1600°C.
