Apiezon L Grease
Apiezon L Grease is a silicone and halogen-free ultra-high vacuum grease suitable for use scientific and industrial applications.
Apiezon L Grease has the best vapour pressure properties of all the Apiezon products and is therefore suitable for use in ultra-high vacuum applications. L Grease is regularly used by highly respected organisations such as The European Space Agency, NASA and NATO.
Apiezon L Grease is designed for use 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 L Grease is a silicone and halogen-free ultra-high vacuum grease which:
exhibits an extremely low vapour pressure of 7 x 10-11 Torr at 20°C
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
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 solvents
Available to buy in 25g or 50g tubes.
