Base Oil for PFPE Grease

RUI-J series products is an ideal for the use in lubricating fluid and grease as base oil especially when pumping strongly oxidative substances like oxygen, ozone or nitric oxides as well as highly reactive substances like halogens and hydrogen halides.

RUI-J series products will not polymerise under the influence of high energy radiation.
