Apiezon AP100 grease Apiezon AP100 vacuum 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 AP100 Grease is a silicone-free ultra high vacuum lubricating grease which: has anti-seize properties, making it an effective protector and lubricant in ultra-high vacuums exhibits extremely high levels of lubricity demonstrates an extremely low vapour pressure of 7 x 10-11 Torr at 20°C is recommended for use at ambient temperatures does not suffer from contamination problems associated with silicone based greases such as ‘creep’ or ‘carry over’ is easy to clean and remove using hot water and an aqueous glassware detergent or hydrocarbon solvents The unique properties of Apiezon AP100 lubricating vacuum grease mean it is frequently used to protect stepping motors and gearboxes from corrosion and abrasion, particularly when they are subjected to high load conditions. AP100 is also used to prevent seizure in stopcocks, taps and small metal fastenings. The creep resistance of Apiezon AP100 benefits scientific and semiconductor users alike. AP100 helps to increase the accuracy of analytical techniques and improve yields in semiconductor manufacture by contamination avoidance. In addition, AP100 is used for surface coating applications where silicone contamination can lead to poor surface adhesion and incomplete coating defects.

Apiezon AP101 with its superior anti-seize properties is typically used to maintain the smooth operation of stopcocks and taps in scientific and industrial settings. Coupled with easy separation of ground or polished glass joints AP101 is an excellent general purpose grease for laboratory use. The value of Apiezon AP101 anti-seize properties is not limited to laboratory or glassware use, but is equally effective when used on metal equipment which may be subject to seizure or corrosion. Just a small amount of AP101 on fastenings which, when exposed to corrosive environments would normally jam solid, will ensure they are protected. Apiezon AP101 is an excellent general purpose grease for sealing joints and is ideal for use in critical lubrication conditions such as highly stressed bearings. Being hydrocarbon based, Apiezon AP101 does not suffer from the problems of “creep” or “carry over” which is traditionally associated with silicone greases. It reduces sample contamination and consequently the risk of interference in analytical techniques such as infra-red and mass spectrometry. Additionally AP101 can be used with confidence in paint spraying and metal deposition processes.

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 As an ultra-high vacuum grease with excellent lubrication properties and radiation resistance Apiezon L Grease is used for many diverse applications. In particular, L Grease is commonly used in scientific and industrial sealing and lubrication applications. Apiezon L Grease has been especially formulated to provide excellent lubrication while maintaining an efficient gas seal and is therefore widely used in the manufacture and servicing of high performance vacuum pumps. Using silicone-free Apiezon L Grease avoids the problems of ‘creep’ and ‘carry over’ which can often lead to sample contamination. Therefore, it is regularly used in analytical techniques such as infrared or mass spectrometry where sample contamination must be avoided. Similarly, ‘creep’ can cause problems in industrial paint or metal deposition processes as trace amounts of silicone on surfaces can prevent the adherence of paint, leading to poor coverage. When using silicone-free Apiezon L Grease this is not a problem. As a halogen-free product Apiezon L Grease has a built-in resistance to irradiation. Other high vacuum greases such as esters, silicones or halogenated paraffins decompose at radiation levels of 0.1 MGy or less. In contrast, L Grease maintains excellent lubrication properties in high radiation applications, demonstrating only a small increase in stiffness when irradiated with 4 MeV electrons to 1 MGy.

We specifically recommend that Apiezon T Grease is used for both sealing and lubrication in medium temperature environments (but not for highly stressed bearings). T Grease confers excellent cohesive strength and therefore when joints are mated they stay mated, forming an extremely efficient, gas tight seal. Apiezon T Grease provides extra cushioning between mated surfaces, and is highly effective in protecting fragile glass to glass joints. The strong absorption properties of Apiezon T Grease give it a powerful ‘gettering’ action . This is of considerable value in the electronics industry where scrupulous cleanliness of metal surfaces is required. Apiezon T Grease has also found a niche as a barrier to oxygen transmission in both vacuum and non-vacuum situations. Apiezon T Grease Vapour Pressure Graph MSDS Technical Data Sheet
