Fluorinated Greases

Excellent chemical stability based on fluorinated base oil

Achievement of Long-Term Lubrication with Excellent Chemical Stability

  • Exhibit stable performance over long periods with low oxidation degradation or evaporation, thanks to a fluorinated base oil (PFAE).
  • Excellent load bearing performance resulting from a combination of a PTFE thickener, solid lubricant additives, and a fluorinated base oil.
  • Can be used over a wide temperature range, from low to high, because of relative immunity to the effect of temperature changes.
  • Suitable even for use under vacuum conditions or in a clean room, thanks to the low vapor pressure of the base oil.
  • Can be used in demanding environments with exposure to chemical or solvent splashes or for plastic and rubber lubrication.

Prior to using a fluorinated grease, please take note of the following points:

  1. As fluorinated greases have a stable chemical structure, they are not compatible with other synthetic or mineral oils. If a fluorinate grease is applied to a surface on which any antirust agent, grease or the like has previously been applied, it is likely to be repelled from the surface, resulting in seizure.
  2. Although fluorinated greases are less toxic than general-purpose greases and non-flammable, they emit fluorine gas if heated to 260°C or more as a result of thermal decomposition of their ingredients. For this reason, be sure to use them within the specified temperature range.
  3. To remove old fluorinated grease, cleaning with a highly fluorinated organic solvent, such as our Sumitec Solvent 72 (5 kg), is effective.
