Features

  • Remains stable under the most severe operating conditions such as pumping Lewis acids, halogen acids, halogens, uranium hexafluoride, and the strongest hydrous acids
  • Nonflammable under all conditions
  • Ideal for pumping oxygen, ozone, or spontaneously combustible chemicals such as silane or phosphine
  • Does not polymerize under ionizing radiation or when hot fluid is exposed to atmosphere

NOTE: Select Fomblin diffusion pump fluids by vapor pressure: Choose Fomblin 18/8 for ultimate pressures of 10-8 Torr and Fomblin 25/9 for 10-9 Torr range (without LN2 trapping).

Shelf Life

It is strongly recommended using all fluids and greases at the time of receipt, however when storage is necessary, rotate older stock into use first and observe the recommended parameters listed below.

Fomblin

The shelf life Fomblin Y-LVAC, Y-HVAC and LC products is a minimum guarantee of 5 years. As far as the chemical stability is concerned it is over 20 years based on our experience. Within this time frame the Fomblin/Galden products, if stored under normal conditions in the original sealed containers, will maintain their chemical-physical properties unchanged.

Fomblin and Galden samples are retained for 5 years to check and guarantee the conformity to the specifications over this time frame.

Shelf Life of Fomblin Grease is a minimum of 5 years; in this case although there won't be problems in terms of chemical stability there can be oil separation over time, which is normal.

Fomblin Perfluorosolv fluids have a guaranteed shelf life of a minimum of 5 years from date of shipment if stored in the original sealed container at ambient temperatures.
