20080268204 | MULTIPLE LAYER POLYMER INTERLAYERS HAVING AN EMBOSSED SURFACE - The present invention provides multiple layer interlayers having a relatively soft inner layer and relatively stiff outer layers that can be laminated without unacceptable optical distortion and used in various multiple layer glass panel type applications. | 10-30-2008 |
20090286046 | Multiple Layer Polymer Interlayers Having An Embossed Surface - The present invention provides multiple layer interlayers having a relatively soft inner layer and relatively stiff outer layers that can be laminated without unacceptable optical distortion and used in various multiple layer glass panel type applications. | 11-19-2009 |
20110094665 | Multiple Layer Polymer Interlayers Having a Melt-Fractured Surface - The present invention provides multiple layer interlayers having a soft inner polymer layer and relatively stiff outer layers that can be laminated without unacceptable optical distortion and used in various multiple layer glass panel type applications. Multiple layer interlayers of the present invention have surface topography that is formed by controlling the melt fracture that occurs at the exposed surface of the interlayer, or individual layers of the multiple layer interlayer, during formation of the interlayer. By precisely controlling the surface topography of the interlayer, lamination of the interlayer with a rigid substrate does not lead to unacceptable optical distortion caused by the transfer of the surface topography through outer, stiffer layers into softer, internal layers of the interlayer. | 04-28-2011 |
20120135191 | Systems, Methods and Apparatuses for Direct Embossment of a Polymer Melt Sheet - A continuous single-stage embossing station comprised of two (2) temperature controlled engraved rollers which is located immediately after the extrusion die in the manufacturing process for multi-layer laminated glass panels and allows for dual simultaneous embossment of both sides of a polymer melt sheet and produces a polymer interlayer sheet with increased permanence, embossed retention values and decreased incidence of mottle and stack sticking peel force values. Also disclosed herein is an embossed polymer interlayer sheet with a first side, a second side and an embossed surface on at least one of the sides, with a surface roughness Rz of 10 to 90 microns on the embossed surface, a permanence of greater than 95% when tested at 100° C. for five (5) minutes and an embossed surface retention of greater than 70% when tested at 140 ° C. for five (5) minutes. | 05-31-2012 |
