EV-Silicon Oil-730

For diffusion pumps
 EV-Silicon Oil-730 (Phenyl-Methyl Silicone) is an excellent compromise oil having a mid-range boiling point approaching 704. Extensively used in heat treatment and investment casting applications where a high auto-ignition oil temperature is desirable. EV-Silicon Oil-730 provides exceptionally high resistance to oxidation and thermal stability when compared with mineral diffusion pump oils.

EV-Silicon Oil-730 is a bespoke diffusion pump oil that may be used as a direct replacement for the discontinued Wacker AN30.
EV-Silicon Oil-730 is an intermediate upgrade between EV-Silicon Oil-702 and EV-Silicon Oil-740 for those who want extra performance and faster pumping speeds than traditional 702.
