  • Publication number: 20110094665
    Abstract: 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.

  • Patent number: 7674421
    Abstract: A guide catheter shaft is formed from an inner tube structure and a multilayer sheath around the inner tube structure. The multilayer sheath includes an intermediate sheath and a shrink tube layer. The intermediate sheath is disposed around the inner tube and realized from a melt-processible first polyether-block amide material. The shrink tube layer is disposed around the intermediate sheath and realized from a different second polyether-block amide (e.g. a cross-linked polyether-block amide material) having a shrink temperature range greater than a melt temperature range of the first polyether-block amide material. The resulting structure is heated at a temperature within the shrink temperature range such that the outer shrink tube layer shrinks and the intermediate layer melts to thereby bond the multilayer sheath to the inner tube.
