Description
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.
