High Thickening Efficiency

Fluoro GE sub-micron PTFE are powders made from emulsion grade virgin PTFE. These products cover a range of molecular weights to determine dispersability, thickening and performance properties. Due to the small particle size, the GE products have a larger specific surface area when compared to other PTFE.

Thickening Efficiency:

  • Increases as primary particle size (PPS) decreases
  • Increases as Bulk Density decreases
  • Increases with Molecular Weight
    • Using a PTFE with same particle size/density, but much larger MW, may lead to gummy consistency at the same loading in a given grease

  Anti-Wear Performance:

  • Increases as MW decreases
  • PPS can also affect anti-wear performance
    • Depends on contact surface (point, line, plane)
    • Submicron particles better for point/line contacts
    • Larger particles are better for planar contacts
  • Our studies have shown that higher molecular weight leads to higher 4 Ball friction force, a higher likelihood of a slip-stick event, and this results in a larger wear scar when compared to a lower molecular weight PTFE.
Fluoro GE products are used for applications such as aerosol lubricants, mold release, gasket grease, extreme pressure grease, bearing lubricants and other products. This product can be used in NSF grade greases and lubricants.
