ULTRA TEMP 1401 MILLBOARD is a strong, thin, dense board with excellent insulating characteristics It is made from ceramic fiber, clay, inert fillers and a small amount of organic binders to increase handling strength. It contains no asbestos and can bcell nameasily substituted for asbestos bearing millboards. It is smooth and flat and can be used in a variety of environments up to 2300ºF (1260ºC). It maintains its integrity through-out a wide temperature range and is easily die cut.
