  • Multilayer structure for polymers
    Patent number: 7862899
    Abstract: The invention relates to a multilayer structure which is especially suitable for the anti-scratch sealing and decorative metallic finishing of topographically defined polymer surfaces, and to vacuum methods for building up the series of layers.
    Type: Grant

    Date of Patent: January 4, 2011
    Assignee: Rehau AG & Co.
    Inventors: Thomas Schettler, Edgar Quandt
  • PROCESS FOR MODIFYING A SILICONE RUBBER SURFACE
    Publication number: 20090092843
    Abstract: The process for modifying a silicone rubber surface by coating with a functional layer is characterised in that a silicate-containing functional layer is deposited from a flame on the silicone rubber surface, as a result of which the surface is modified in such a way that it has a very low adhesion or tackiness.

  • Heating element on the polymer inside surface of a motor vehicle front-end module/bumper in an operative connection to a radar transmitter/receiver unit
    Patent number: 7326894
    Abstract: A heating element for an inside surface of a front-end module/bumper for a motor vehicle. The heating element is operatively connected to a radar transmitting/receiving unit. The heating element includes a heating film formed of a polymer, an array of conductor strips integrated into the heating film, and an electronic control element that controls the conductor strips. The array of conductor strips is divided into an inner region through which a radar beam from the radar transmitting/receiving unit is transmitted, and an outer region through which the radar beam is not transmitted. The conductor strips in the inner region are inclined by angles of about 45° to about 90° relative to a polarization plane of the radar beam. The conductor strips in the outer region are arranged in a meandering pattern.
