Abstract (en)

Lubricating greases comoprising: A) from 65.1 to 95% by weight of a (per)fluoropolyether oil having a viscosity at 20 DEG C in the range 20-2,000 cSt; B) from 5 to 34.9% by weight of powder of polytetrafluoroethylene or of a tetrafluoroethylene copolymer with another monomer having an ethylene type unsaturation, said powder obtainable by coagulation with an electrolyte of an aqueous latex containing polymeric particles having sizes comprised between 5 and 100 nm, wherein the grease has a surfactant content lower than 20 ppm and a water content lower than 100 ppm.
