Elastic, heat-insulating shapes of ceramic, refractory or fireproof fibers and, where needed, further refractory or fireproof substances, and temporary or inorganic binders, as well as a process for the preparation thereof. The heat-insulating shapes are characterized by the fact that they contain 5 to 40 weight % of fibrids comprised of organic polymers, as a result of which they have elastic properties and can be formed with ease at moderate temperatures. In preparing these shapes, a customary aqueous dispersion containing the fibers and binder is mixed with the fibrids of the organic polymer, and water is removed therefrom and the shapes are otherwise produced in a known manner. |
