Apiezon M Grease

Apiezon M Grease is a silicone- and halogen-free high vacuum grease and is ideally suited to all manner of high vacuum applications. Its inherent versatility means M Grease is also frequently used for non-vacuum purposes in both scientific and industrial settings and it is approved for use by NATO.

Apiezon M Grease is designed for use in high vacuum environments at ambient temperatures (generally between 10 to 30°C / 50 to 86°F). If you are looking for a grease capable of performing at higher temperatures, Apiezon AP101 or Apiezon H Grease may be more appropriate.

Apiezon M Grease: High Vacuum Grease Properties

Apiezon M Grease is a silicone- and halogen-free high vacuum grease which:

• does not suffer from contamination problems associated with silicone based greases such as ‘creep’ or ‘carry over’
• provides excellent lubrication
• is recommended for use at ambient temperatures
• exhibits a vapour pressure of 1.7 x 10^-9 Torr at 20°C
• has built-in radiation resistance
• has powerful ‘gettering’ action, meaning it absorbs potentially harmful grease and chemical impurities on metal and glass surfaces
• is easy to clean and remove as it is soluble in hydrocarbon and chlorinated solvents
