Low saturated vapor pressure,narrow distillation range,high molecular weight and pumping speed.
Performance
1. Low saturated vapor pressure,narrow distillation range,high molecular weight
and pumping speed.
2. When heated to its boiling point,the oil will eject in supersonic speed to create a
vacuum environment rapidly.
3. Reasonable chemical compositions, perfect oxidation and thermal stability.
4. Low back-streaming rate,oil vapor will condense into new fluid as soon as it touches cold wall.
Application
1. Suitable for vapor diffusion pumps,it is available according to the final pressure only.
2. Applicable to vacuum distillation,vacuum metallurgy,vacuum coating, vacuum furnace, and etc.
3. Also be used as working fluid of diffusion pump in industries,such as electronics, aeronautics,nuclear and etc.
