Ceramic Fiber Blanket is a new kind fire-resistant heat insulation material with white colour. Without any bonding agent, good tensile strength, tenacity and fiber structure can be kept while using under the normal and oxidation condition.
· Heat insulation for back lining of high temperature industrial furnace;
· Heat surface lining materials for porcelain furnace, heat treatment furnace of mechanical and metallurgy and other industrial furnaces.
· The thermal capacity and thermal conductivity are lower than similar products;
· The fiber diameter is uniform, and the slag ball content is lower in products with the same density;
· Stable chemical performance without pulverization;
· The same body density product hashigher tensile strength;
· High flatness, cutting construction without burrs;
· Good thermal shock resistance and long service life;
