Ceramic Fiber Blanket (6# Density, 2300°F), 1 in. Thick x 48 in. Wide x 60 ft. Long (Total Of 20 sq. ft.) is used for various applications in the metal, ceramic, and glass production industries as well as in fire protection and aerospace applications. Ceramic fiber blankets are made from bulk fibers produced by the most modern spinning process, giving exceptional length and uniform distribution. Ceramic fiber blankets are manufactured with pure alumina-silica, forming a continuous blanket, mechanically sewed with double needle in order to provide better integrity to the surface on both sides of the blanket, a greater resistance in kaolin types and a higher purity. It contains no binder or other added constituents.
