Abstract
The novel composition of the present invention comprises a paper-like sheet material or a non-woven mat which contains water-insoluble gypsum anhydrite microfibers and a cellulosic binder, such as cellulose fibers, optionally with glass fibers, which has surprising fire-retardant properties. Typical paper processing methods or wet process mat techniques are utilized in preparing this material. The flexible gypsum microfiber sheet or mat of this invention may be used as microfiber insulation, particularly in a fire retardant barrier.
