Ceramic fiber blanket is high strength, needled insulating blanket that is made from spun aluminum silicate fiber bulk. The combination of long spun fibers and needling operation produce tough,resilient and strong blankets,which resist tearing both before and after heating. Ceramic fiber blanket is completely inorganic do not contain binder or lubricant and do not emit any fumes or smell during the first firing. It is available in a variety of temperature grades,densities,and sizes, blanket can be folded,compressed and encapsulated to produce modules.
