Performance1. Low saturated vapor pressure,narrow distillaiton range,high molecular weight and pumping speed.2. When heated to its boiling piont,the oil will eject in supersonic.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.Application1. Suitable for vapor diffusion pumps,it is available according to the final pressure only.2. Applicable to vacuum distillation,vacuum metallurgy,vacuum coating,vacuum fumace,and etc.3. Also be used as working fluid of diffusion pump in industries,msuch as electronics,nuclear and etc.Typical DataItem / ModelHFV K46HFV K68HFV K100Kinematic viscosity (40),mm2 /s41.4 50.661.2 74.890 110Average Molecular Weight380420450Flash Poin220230250Saturation Vapor Pressure,kpa5.0×10-91.0×10-95.0×10-10Limit vacuum,kpa7.0×10-85.0×10-83.0×10-8
