Grease Perfluoropolyether Grease for Bearing Lubricating

PFPEs - perfluoropolyethers are polymeric chains built upon just three elements aa carbon, oxygen and fluorine.

Perfluoropolyethers (PFPEs) are polymeric chains built upon just three elements – carbon, oxygen and fluorine. Each contributes significantly to the material’s ability to act as a high-performance lubricant in the harsh environments. The absence of hydrogen, a common element of traditional lubricants, contributes further to PFPE’s enhanced thermo-oxidative stability.
