Moderate Thickening Efficiency and Wear Resistance

Fluoro GS  powders are made from unsintered, suspension grade virgin PTFE. These products  are characterized by the uniform, crystalline structure of PTFE provide increased slip and abrasion properties.

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.

These products can be added with moderate change to the viscosity of the system. They impart excellent lubricity and wear resistance. Fluoro GS products are used in applications such as chain lubricants, brake applications, food grade grease, and low temperature greases.
