Product Description

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.

Features

Low vapor pressure
Chemical inert
Excellent solvent resistance
High thermal stability
Good lubricity
Excellent compatibility with metals, plastics, elastomers
Low surface tension
Good radiation stability
No flash or fire point
Non-toxic
Environmental friendly
