Abstract (en)
[origin: WO0073232A1] The present invention provides a glass fiber composition comprising: 55 to 63 percent by weight SiO2; 22 to 26 percent by weight CaO; 12 to 16 percent by weight Al2O3; 0 to 1 percent by weight MgO; 0.05 to 0.80 percent by weight Fe2O3; 0 to 2 percent by weight Na2O; 0 to 2 percent by weight K2O; 0 to 2 percent by weight TiO2; 0 to 2 percent by weight BaO; 0 to 2 percent by weight ZrO2; and 0 to 2 percent by weight SrO, and at least one material selected from the group consisting of: 0.05 to 2 percent by weight B2O3; 0.05 to 2 percent by weight Li2O; 0.05 to 2 percent by weight ZnO; 0.05 to 2 percent by weight MnO; and 0.05 to 2 percent by weight MnO2. In one nonlimiting embodiment of the invention, the glass composition has a forming temperature of no greater than 2300 DEG F based on an NIST 717A reference standard, a liquidus temperature of no greater than 2160 DEG F, a ratio of SiO2 to RO of no greater than 2.65, and a DELTA T of at least 65 DEG F.
