| Silicone Fluids for Diffusion Pump |
SiSiB® PF8704 Diffusion Pump Fluid is a silicone diffusion pump fluid. This fluid's low vapor pressure and thermal stability make it popular in processes such as vacuum coating, metallurgical work, and various other applications.
SiSiB® PF8705 Diffusion Pump Fluid is designed to produce an ultra high and ultra clean vacuum. With the use of traps, SiSiB® PF8705 is capable of attaining a pressure of 10-11 torr. Without traps, a pressure of 10-9 torr can be achieved.
