Mechanical carbon seal material : Carbon graphite is an ideal seal material in every aspect. Self lapping and flexible enough to conform to the mating face, very hard and resistant to wear, and self lubricating. It's also lubricated by almost any fluid so the media being sealed can act as a lubricant. It's impervious and resistant to most chemicals.
1) Metal impregnated carbon: Antimony, Copper, or Babbitt alloys are used as filler for applications requiring higher working temperatures or higher strength. 2) Resin bonded carbon: An economic, pressed to size material for large volume requirements 3) Resin impregnated carbon: Furan resin, Phenolic resin, or Epoxy resin are used as filler to decrease the porosity of carbon
