  • Patent number: 10879510
    Abstract: Acid-resistant and biosoluble glass compositions and products made therefrom. The glass compositions exhibit acid resistance, durability in white water as may be used in a wet laid fabrication process, and good biosolubility. In another aspect, a glass fiber mat is made from such a glass composition, and may be used in the manufacture of lead-acid batteries, for example as a pasting material or battery separator.

  • Publication number: 20160273156
    Abstract: Fiberglass products with increased flame resistance are described. The products may include fiberglass-containing thermal insulation that include a plurality of glass fibers coated with a phosphorous-containing flame retardant. The flame retardant may include an organophosphorous compound having a substituted or unsubstituted organophophorous group bonded to a substituted or unsubstituted amide group by a substituted or unsubstituted alkyl group. The fiberglass products may further include fiberglass composites that are about 50 wt. % to about 98 wt. % glass fibers, about 2 wt. % to about 50 wt. % of a binder; and a phosphorous-containing flame retardant. Also described are methods of making fiberglass products with increased flame resistance. These methods may include the steps of contacting glass fibers and/or fiberglass products with a flame retardant mixture that includes a phosphorous-containing compound.

  • Publication number: 20130260980
    Abstract: Methods for forming glass compositions from cullet include providing the cullet to a submerged combustion melter and melting the cullet with the aid of heat generated upon the combustion of a hydrocarbon from landfill gas and, in some cases, a polymeric material, in the presence of an oxidant. The melted cullet is then directed to a fiberization unit to generate a glass composition, such as vitreous fiber. The glass composition can be used to form various structural components, such as glass fiber insulation. Methods and systems provided herein can be used to form low global warming potential products.

  • Patent number: 7842631
    Abstract: 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.
