There are PFPE Oils with D-type, K-type, Y-type and Z-type structures. PFPE Fluids with D-type has a non-shielding structure and its stability is slightly poor. K-type PFPE has a full “shielding” structure with branched chains, its stability is the best. The performance of Y-type and Z-type PFPE oils is between the two. Our company’s PFPE products belongs to full “shielding” K-type structure.
Perfluoropolyether(PFPE) Oil is mainly used in the areas with heat, chemicals, solvents, corrosion, toxicity, flammability, etc. It can be used in original form or to be formulated into greases for the specific applications in the industries of chemical, electronic, cosmetic, machinery, aerospace, nuclear, etc that require high lubricating performance.
PFPE Base Oil For Grease 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.

PFPE Vacuum Pump Oil Topda K-L Grades are perfluorinated polyether inert fluids with only carbon (C), fluorine(F), and oxygen(O) atoms on the molecular chain. They are ideal for use in vacuum pumps as sealing & lubricating fluid and working fluids especially in the systems which are exposed to strongly oxidative substances like oxygen, ozone or nitric oxides as well as highly reactive substances like halogens and hydrogen halides. Because of their high stability and safety, especially the high reliability of working under particularly harsh conditions, no working medium can be comparable to perfluoropolyether oil in such harsh environment.
