ArChine Diffutech 702
Vacuum Diffusion Pump Oil
Production Description:
Equivalent Brand: DOW Corning 702
ArChine Diffutech 702 oil is a kind of general-purpose oil designed for fast pumping of large volumes of gas. It is used to produce vacuums in the range of 10-5 to 10-7 torr. It possesses excellent heat-stability, good resistance to oxidation and radiation. Its vapour pressure is very low under room temperature, and changes sharply with the variation of temperature.
