Product Description
Equivalent Brand: Dow Corning 705, MT-705, and HIVAC-F-5 Diffusion Pump Oil RJ-275 is a colorless to light yellow transparent oily, single-component fluid designed for ultrahigh vacuum applications in the range of 5 (10 ~10 ) torr (untrapped).
The vapor pressure and backstreaming rate of RJ-275 is so low that the use of 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.
Technical Index Property Specification Chemical composition Pentaphenyl trimethyl trisiloxane Ultimate Vacuum, torr (untrapped) 5 (10 ~10 )
