Radio Frequency (e.g., 13.56 Megahertz, Etc.) Patents (Class 264/421)
  • Patent number: 8470897
    Abstract: A process for devulcanizing crosslinked elastomer particles comprising applying an alternating electric field to a composition comprising crosslinked elastomer particles under compression. The alternating electric field preferably has a frequency between 1 and 100 MHz and a voltage between 1000 and 10,000 V, and may be applied between an apparatus that continuously conveys the particles through the field.
