|< Diffusion Pump Oil
The diffusion pump oil used in high vacuum technology requires thermal oxidation resistance and low vapor pressure at cooling temperature. < \< Currently, mineral oils, esters, polyphenylene ether and silicone oils are mainly used. Among them, silicone oil has the best performance,
: . Contact information: <
It has high thermal oxidation stability, small viscosity-temperature coefficient, narrow boiling point range, steep vapor pressure curve and low vapor pressure at normal temperature. , low freezing point, chemically inert, non-toxic, odorless and non-corrosive. Therefore it can be used for a long time at < < ℃, and allows use at higher temperatures under vacuum
