  • LOW DIELECTRIC GLASS FIBER
    Publication number: 20110042129
    Abstract: A glass fiber having a low dielectric constant and low dielectric loss tangent consists essentially of by weight, as a glass composition, 52 to 60% of SiO2, 11 to 16% of Al2O3, 20 to 30% of B2O3, and 4 to 8% of CaO, and substantially no MgO, substantially no Li2O, substantially no Na2O, substantially no K2O, and substantially no Ti2O. The glass fiber also may contain up to 2% F2 by weight. The glass fiber is ideal for use as reinforcement for printed wiring boards, and has excellent dielectric properties at frequencies of about 18 GHz or higher.
    Type: Application

  • Basalt compositions and their fibers
    Patent number: 4560606
    Abstract: Fiberizable basalt compositions are disclosed. The fibers are produced from natural basalt rock modified with alkaline earth metal oxides. The fibers can be used to make low density composites for ceiling tile or boards.
