Product Description

Description

PFPE Oil Topda B Grades are perfluorinated polyether inert fluids with only carbon (C), fluorine(F), and oxygen(O) atoms on the molecular chain. They not only maintain the excellent properties of perfluoropolyether fluids, but also has many unique properties, such as excellent high temperature stability, good low temperature properties, low evaporative loss and high viscosity index. They are widely used as base oil to formulate PFPE greases for specific appliations to meet the most challenging demands.
