Apiezon

Apiezon AP100 Grease is a silicone-free vacuum grease and lubricant. Containing PTFE, AP100 exhibits extremely high levels of lubricity and has been shown to provide eight times the level of lubrication offered by standard, petroleum-based lubricating greases. Apiezon AP100 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 suitable for use scientific and industrial applications. 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 H Grease is a silicone-free high vacuum grease perfectly suited for use at high temperatures in both scientific and industrial applications. H Grease has exceptional ‘stiction’ and thermal conduction properties and has gained prestigious approvals from a variety of international organisations, including BAE Systems, the European Space Agency and NASA.
Apiezon H Grease: High Temperature Vacuum Grease Properties.
Apiezon H Grease is a silicone-free high temperature vacuum grease which:
-performs well under a wide range of temperatures, from -10 to +240°C, and retains its optimum consistency at temperatures between +10 and +110°C 
-rather than melting, actually becomes stiffer as temperature increases and therefore is not recommended for highly stressed bearings
-has excellent heat transfer properties
-conducts heat away from the site of operation, reducing the danger of overheating and damaging heat-sensitive components
-exhibits good ‘stiction’ or sticking power
-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
-exhibits a vapour pressure of 1.7 x 10-9 Torr at 20°C

A well‐proven and recommended high‐vacuum grease for electron beam instruments. Grease L is a petroleum hydrocarbon grease, containing no additives. Very low vapour pressure (@20°C of 8×10‐¹¹ torr), high vacuum grade. Type L is widely used in electron microscopy where moderately high column temperatures and high vacuum requirements demand a vacuum grease with extraordinary characteristics. Type L is also used in the stationary phase of gas liquid chromatography, and may be used on all ground joints in a vacuum system (not for stopcocks). Its solubility is as follows: in ethanol at 20°C‐0.003%; 60°C‐0.005%; 100°C‐0.011%; 150°C‐0.011%. Grease L softens and melts at about 47°C and it is not recommended for joints where temperatures exceed more than 30°C in use. Grease T is recommended for these higher temperatures.

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.
