摘要： Provided are glass compositions with higher softening point temperatures than conventional glasses, which improve flame penetration test performance of flexible duct insulation. In particular, the glass compositions have a softening point in the range of about 1230-1276° F., a log-3 viscosity temperature in the range of about 1802-1879° F., and a temperature difference between log-3 viscosity and liquidus temperatures of at least 150° F. These glasses are specially formulated to increase softening point while only minimally increasing log-3 viscosity temperature, so as to allow fiber insulation manufacturing without requiring increased energy use.
