Abstract
High temperature glass fibers suitable for use as textile and reinforcements are specifically adapted to be used in high temperature applications such as sound absorbing material in engine exhaust mufflers. The glass fibers have compositions of up to 72 Mole % SiO2, 20 mole percent Al2O3, 22 mole percent alkaline earth oxides and may include small amounts of alkali oxides and ZrO2.
