Apiezon H Grease
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 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 solvents
exhibits a vapour pressure of 1.7 x 10-9 Torr at 20°C
Available to buy in 25g tubes.
