PFPE Base Oil For Grease

PFPE Base Oil for Grease (B Grades) are chemically inert perfluoropolyether fluids composed only of carbon (C), fluorine (F), and oxygen (O).

They retain all superior properties of PFPE fluids while delivering outstanding high-temperature stability, excellent low-temperature performance, minimal evaporation loss, and high viscosity index.

These fluids are widely used as premium base oils for formulating high-performance PFPE greases to meet the most demanding operating conditions.
