  • Polyimide resins for high temperature applications
    Patent number: 8795799
    Abstract: Polyimide resin compositions that contain an aromatic polyimide, graphite, and acicular titanium dioxide are found to exhibit high thermal oxidative stability. Such compositions are especially useful in molded articles that are exposed to high temperatures, such as bushings, bearings, and seal rings that are used in aerospace, transportation, and materials handling applications.
    Type: Grant
    Filed: September 29, 2011
    Date of Patent: August 5, 2014
    Assignee: E I du Pont de Nemours and Company
    Inventors: Robert Ray Burch, Jesus G Moralez, Susan H Tilford
  • Polyimide resins for high temperature wear applications
    Patent number: 8507615
    Abstract: Polyimide resin compositions that contain an end-capped rigid aromatic polyimide, graphite and, optionally, a filler selected from sepiolite, attapulgite, kaolinite, or a mixture thereof, are found to exhibit low wear at high temperatures. Such compositions are especially useful in molded articles that are exposed to wear conditions at high temperatures such as aircraft engine parts.
