  • Enhanced performance conductive filler and conductive polymers made therefrom
    Publication number: 20110108775
    Abstract: There is provided a particulate conductive filler which comprises a conductive metal coating formed over a coarse carbon-based core such as graphite between 350 and 1000 microns in size. The conductive filler is used in conjunction with a polymer matrix such as an elastomer typified by silicone elastomer to form composite materials for conductive and electromagnetic interference shielding applications.
    Type: Application
    Filed: January 20, 2011
    Publication date: May 12, 2011
    Applicant: Sulzer Metco (Canada) Inc.
    Inventors: Brian William Callen, William Kimber Walkhouse
