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 % SiO 2 , 20 mole percent Al 2 O 3 , 22 mole percent alkaline earth oxides and may include small amounts of alkali oxides and ZrO 2 .
1. A continuous glass fiber produced from a composition consisting essentially of:60-72 mole percent SiO 2 ,10-20 mole percent Al 2 O 3 ,14.0 to 22.0 mole percent RO, where RO equals the sum of MgO, CaO, SrO and BaO mole percents, wherein the amount of MgO is less than 3 mole percent,0 to 5 mole percent ZrO 2 , and0 to 3 mole percent alkaline metal oxide,wherein the composition has(i) a glass transition tcmperature of at least 1472° F. (800° C.),(ii) a viscosity of about 1000 poise at a forming temperature greater than 2500° F. (1371...
