Name: HFV-MF Vacuum Sealing Oil Model: HFV—MF Brief: Good thermal stability to keep the stabilization of vacuum degree at high temperature.

详细介绍

Performance

※ Perfect oxidation and chemical stability.

※ Good thermal stability to keep the stabilization of vacuum degree at high temperature.

※ Good water and solvent resistance and electrical property.

※ Lower saturation vapor pressure and higher molecular weight.

Application         

※ Suitable for lubricity and sesling of oil-sealed metal contact vacuum valve or central valve.

※ Suitable for lubricity and sealing of metal-to-metal surface,movable part of metal soaked in the sealing oil,such as contact-type vacuum valve or central valve.

※ Widely used in illuminating and other industries.

※ Be equivalent to Japan Moresco MC sealing oil.
