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.
Higher temperatures
Apiezon H grease can be used over a wide range of temperatures from -10 to +240°C, while optimum consistency is retained at between +10 and +110°C.
Thermally conducting
Apiezon H grease is a filled hydrocarbon grease which exhibits excellent heat transfer properties.
Allowing heat to conduct away from a site of operation, Apiezon H grease will reduce the danger of overheating and hence will limit the risk of damage to heat sensitive components.
Under vacuum
Apiezon H grease exhibits good vacuum properties in the low to medium vacuum range at higher temperatures. At lower temperatures Apiezon H grease can be used in the high vacuum range.
Sticking power
Apiezon H grease is a very tenacious grease exhibiting excellent cohesive strength. With Apiezon H grease, gone are the days of loose fitting glassware and mated joints working loose.
Silicone free
As a hydrocarbon based grease, H grease is highly resistant to "creep" or “carry over”, a phenomenon associated with silicone-based products. Silicone has a tendency to travel away from the area of application and contaminate adjacent surfaces.
Easily removed
Apiezon H grease is easily removed by wiping with a soft clean lint free cloth. Any residues of grease can be washed away with warm soapy water, by using any aromatic hydrocarbon solvent (toluene, xylene) or chlorinated hydrocarbons (trichloroethylene).
Compatibility
Apiezon H grease is compatible with a wide range of o-ring materials including:-
- Viton
- Silicone
- Nitrile (>30% nitrile content)
- Nylon
- Polyurethane
- Polyethylene
- Polypropylene
