Property

RUI PFPE oils are perfluorinated polyether inert fluids for use as lubricants in vacuum pumps.RUI fluids are a mixture of fluorinated polymers obtained by a photochemical process that begins with hexafluoropropylene. These fluids have exceptional properties such as:

 

Low vapor pressure

Low toxicity

Chemical inertness

High dielectric properties

High thermal stability

Low surface tension

Good lubricant properties

Good radiation stability

No flash or fire point

 Environmentally acceptable

Good aqueous and non-aqueous solvent resistance

Excellent compatibility with metal

plastics and elastomers

 

Features 

Will not polymerize when exposed to oxygen,ionizing radiation or accelerated subatomic particles. The system stays free of varnish and deposit from fluid decomposition.

Non-flammable

Resistant to oxidation of explosion and hot fluid can be exposed repeatedly to air without harm to the fluid while running the pumps.

Inert to most reactive chemicals,the fluid can be used in direct contact with materials such as UF6,F2,PCl3,BF3,without harm to the fluid.

Application

RUI PFPE oils are suggested for applications requiring the highest quality vacuum suchas in scanning electron transmission microscopes, mass spectrometers, particle accelerators, ion implantation, plasma and vapor deposition processes. In addition, it is suggested for pumps handing reactive gases such as UF6, F2, Oxygen, Ozone, and Tritium, as the fluid can be used in direct contact with those gases without reaction and fluiddegradation.
