  • Glass fiber compositions
    Patent number: 5055428
    Abstract: Based on the discovery that Al.sub.2 O.sub.3 strongly retards the dissolving rate of insulating glass fibers in a synthetic lung solution, glass fibers having low alumina contents have been identified that dissolve significantly faster in lung fluid. Moreover, these glass fibers still have adequate durability for insulation pruposes and have physical properties which allow current processes to fabricate them into insulation.
