Abstract
A sealing material for a scroll-type compressor consists essentially of, by weight, more than 20 and up to 40% PAN-system carbon fiber, 1 to 15% polytetrafluoroethylene resin, and the balance of polyphenylene sulfide resin. Further, not more than 10% hard particles formed of a copper alloy are added to the foregoing components. Thus, there can be provided a sealing material which can be applied to scroll members of a high surface hardness which have undergone Tufram process or Ni-P plating.
