Invoil 46
Invoil 46 is a synthetic (arylalkyldiphenylether) diffusion pump fluid
whose performance combines the best properties of silicones and polyphenyl
ethers. It was developed to accommodate the performance requirements
of such applications such as CRT evacuation, optical coatings, evaporation
and sputtering, vacuum metallurgy, leak detection, and mass spectrometry.
As a result of its unique chemical structure, Invoil 46 offers excellent
thermal stability and radiation resistance. It can attain untrapped
pressures near 10-8 torr. It's ability to recover from
accidental exposure to atmosphere during normal operation is comparable
to that of silicon pump fluids. In addition, deposits formed i the
even of ionizatino or breakdown of the fluid are conductive and do not
accumulate static charges.
