  • Patent number: 6569351
    Abstract: The present invention is directed to a an accelerator-gel additive used to deliver an accelerator such as sulfur, into a system for the production of polymer modified asphalt, vulcanized rubber or similar system. Unlike conventional methods of delivering accelerator into the system, the accelerator-gel additive suspends the accelerator in a gel system thereby preventing the sedimentation of the accelerator during processing. As a result, the polymer and asphalt are processed at lower temperature reducing the production of toxic and flammable gases such as hydrogen sulfide.
    Type: Grant
    Filed: March 14, 2000
    Date of Patent: May 27, 2003
    Assignee: Ergon, Inc.
