<p>TITLE MINERAL WOOL FIBER INSULATION PRODUCTS Mineral wool fiber insulating compositions are provided which may be formed by deposition of a slurry of the composition upon a foraminous mandrel immersed in that slurry. Compositions of the invention are characterized by high-strength and superior processing characteristics and comprise a major portion of mineral wool fibers, a minor portion of colloidal clay, binders and about one percent by weight zinc borate. Zinc borate reduces considerable exotherms associated with conventional organic starch binding agents and also effectively flocculates slurries from which compositions of the invention are deposited.</p> |
