Apiezon N Grease

What is Apiezon N grease?

Apiezon is manufactured by M&I Materials LIMITED.Apiezon N Grease is silicone-free and widely recognised and recommended as the cryogenic vacuum grease of choice.

Apiezon N Grease

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.

What are the properties of Apiezon N grease?

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

can withstand frequent cycling between cryogenic temperatures as low as -273°C and +30°C

is craze-free at cryogenic temperatures

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 solvents

Available to buy in 25g tubes.

When should Apiezon N grease be used?

Apiezon N grease is the first choice sealant and heat transfer medium for low temperature applications. Being pliable at room temperature but freezing solid at cryogenic temperatures, it allows for easy mounting and removal of sensors or samples without causing damage.

Important in low temperature testing of semiconductor chips, laser diodes and crystals, etc., Apiezon N Grease is used to improve thermal contact between the sample boat and cold finger of a cryotstat. This cryogenic thermal contact grease ensures that samples are at the lowest possible temperatures to improve test sensitivities.

Apiezon N Grease can also be used in a variety of applications at ambient temperatures such as when added cushioning is required. N Grease has a special additive which gives it a tenacious, rubbery consistency which absorbs vibrations in equipment, making N Grease invaluable in fragile glass to glass joints, like burette taps, which continually risk fracture.
