Apiezon N Grease

\nApiezon N Grease is silicone-free and widely recognised and recommended as the cryogenic vacuum grease of choice. This cryogenic grease is specially formulated to exhibit craze-free performance characteristics at low temperatures and withstand frequent cycling between cryogenic temperatures as low as -273°C and +30°C. \n

Apiezon N Grease: Cryogenic High Vacuum Grease Properties

\nApiezon N Grease is a silicone- and halogen-free cryogenic high vacuum grease which: \n

• can withstand frequent cycling between cryogenic temperatures as low as -273°C and +30°C
  
• is craze-free at cryogenic temperatures
• \n
• has the ability to fill the micropores of adjoining surfaces, so improve thermal contact
  
• does not suffer from contamination problems associated with silicone based greases such as 'creep' or 'carry over'
  
• exhibits a vapour pressure of 6 x 10^-10 Torr at 20°C
  
• has powerful 'gettering' action, meaning it absorbs potentially harmful grease and chemical impurities on metal and glass surfaces
  
• is easy to clean, use and remove as it is soluble in hydrocarbon and chlorinated solvents
