Abstract
PURPOSE: To enhance sealing and lubricating performance of a packing material by impregnating the material with of a lubricating agent consisting of solid wax and liquid grease in a predetermined ratio into the material's porous portion of the packing material principally made of porous ethylene tetrafluoride resin.
CONSTITUTION: The main portion of this packing material is of porous resin of ethylene tetrafluoride impregnated with a mixture of lubricating agents in a proportion of 5W10% by weight. This lubricating mixture is composed of a solid wax such as vegetable wax or high-viscosity ethylene trifluorochloride and a liquid grease such as liquid paraffine or low-viscosity ethylene trifluorochloride. This liquid grease is to enhance the sealing effect as a feature required for a packing material at normal temperature, reducing thus the torque to be generated, while the solid wax is to enhance the sealing and lubricating performances in the high-temp. atmosphere and reduce the wear of that packing's main portion composed of porous resin of ethylene tetrafluoride.
