ArChine Diffutech 705

Vacuum Diffusion Pump Oil

Production Description:

Chemical structure:

Equivalent Brand: DOW Corning 705, MT-705, HIVAC-F-5

ArChine Diffutech 705 oil is a colorless to light yellow transparent oily, single-component fluid designed for ultrahigh vacuum applications in the range of 5 x (10^-9~10^-10) torr (untrapped). The vapor pressure and backstreaming rate of 705 oil is so low that the use traps or refrigeration is unnecessary for some ultra-high and ultra-clean vacuum applications. It has the highest phenyl content of all silicone diffusion pump oils and the best resistance to radiation.
