Abstract
Elastic foamed products or articles having a much better heat resistance than that of the asbestos fiber foamed mass, prepared by drying of an aqueous fiber-dispersed slurry retaining bubbles and consisting essentially of inorganic fibers, synthetic fluormica of the non-restrictive swelling type and surface active agents. In the elastic foamed products, the inorganic fibers having films of the fluormica formed therebetween are evenly entangled with each other, said films having bubbles retained therein.
