  • Patent number: 7351468
    Abstract: This invention relates to thermoplastic interlayers for laminated safety glass with superior vacuum de-airing at elevated temperatures and superior tacking and edge sealing properties. The sheeting has surface pattern on at least one of the surfaces characterized by flat surfaces with substantially uninterrupted channels for airflow in at least two non-parallel directions. The channels allow for rapid de-airing while the area roughness parameter ratio ARp/ARt in the range of 0.52 to 0.62, ARt being less than 32 ?m, and area kurtosis less than 2.5, allow for ease of tacking of the interlayer onto glass and edge sealing after de-airing has been completed. Said surface pattern may also be superimposed onto a pattern which is generated by melt fracture or other means on at least one side to enhance de-airing and aid edge sealing.

  • Patent number: 5908674
    Abstract: This invention comprises an impact-resisting glazing structure having a support frame and a multilayered composite secured in the frame wherein the composite comprises two sheets of glass spaced apart by an interior spacer positioned along the periphery of the glass sheets with a polyester film adhered to the interior surface of one of the glass sheets. The polyester film has an asymmetric orientation of crystals and molecules in the amorphous regions and having an in-plane distribution of crystalline and amorphous phases in which the (100) planes of said crystals lie in the film plane and wherein in the film, said crystals have chain axes oriented toward the transverse direction such that dominant physical properties are obtained in the transverse direction.
