Apiezon H High Temperature Vacuum Grease, 25 Gram Tube
Apiezon H is designed for applications at higher temperatures and of all the Apiezon greases, is the formulation for the highest 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. There are a growing number of applications for Apiezon H outside of the vacuum area, for example, it is used on a heatsink fan for a computer central processing unit (“CPU”). Apiezon H grease exhibits good vacuum properties (ultimate vapor pressure 1.7×10-10 Torr at 20°C) in the lower to medium vacuum range at higher temperatures, while at lower temperatures, Apiezon H grease can be used in the high vacuum range. Apiezon H 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. Apiezon H grease is manufactured from a unique feedstock containing a high proportion of branched and unsaturated hydrocarbons. These complex structures give Apiezon H grease a very high molecular weight and consequently, strong powers of absorption, particularly for other hydrocarbon molecules. Strong absorption properties ensures that Apiezon H grease has powerful “gettering” action, that is, the power to absorb greasy or chemical impurities on metal and glass surfaces. This is of considerable value in the electronics industry where scrupulous cleanliness of metal surfaces is required.

Product Overview – Apiezon H High Temperature Vacuum Grease:
The Apiezon H family of hydrocarbon high vacuum greases has been serving the market for many years and includes lubrication products highly regarded worldwide for their quality, consistency, and excellent performance within vacuum applications. The greases are silicone-free and highly resistant to creep – the undesirable phenomenon traditionally associated with silicone-based greases.
Apiezon H Grease is a silicone-free high vacuum grease perfectly suited for use at high temperatures in both scientific and industrial applications. Apiezon H Grease has exceptional thermal conduction properties and has therefore gained prestigious approvals from a variety of international organizations, including BAE Systems, the European Space Agency and NASA.
Apiezon H Grease performs well under a wide range of temperatures, from -10 to 240 degrees Celsius, and retains its optimum consistency at temperatures between 10 and 110 degrees Celsius. Contrary to melting, Apiezon H Grease stiffens as the temperature increases and is therefore not recommended for highly-stressed bearings. Apiezon H Grease likewise has excellent heat transfer properties. It conducts heat away from the site of operation, reducing the danger of overheating and damaging heat-sensitive components. The grease exhibits favorable sticking power and absorbs potentially harmful grease and chemical impurities on metal and glass surfaces. It is easy to clean and remove as it is soluble in hydrocarbon and chlorinated solvents.
Applications of Apiezon H High Temperature Vacuum Grease:
As a high temperature, low-to-medium range vacuum grease with excellent sticking power and favorable thermal conduction properties, Apiezon H Grease is used for many diverse applications. In particular, the grease is commonly utilized within scientific and industrial high temperature sealing applications. It is ideal for use with laboratory glassware and is favored by the electronics and space industries, where the high thermal conductivity of the Apiezon H makes it the ideal vacuum grease in situations where heat sink media require adhesion.
Apiezon H is designed for applications at higher temperatures and of all the Apiezon greases, is the formulation for the highest temperatures. Nothing in life is without trade-offs and in this case, the ultimate vapor pressure rating is a bit less attractive than Apiezon L although it is comparable to Apiezon M.
Apiezon H grease is the ideal choice of grease for use at higher temperatures in a wide variety of applications in both science and industry. Its characteristic properties would suggest it is good at high temperatures, it has decent thermal conduction properties, good “stiction” and is designed for use in the low to medium vacuum range. Whatever chemical vapors that do get produced at elevated temperatures would contain only petroleum hydrocarbons and under no circumstances would they contain silicones or halogenated compounds.

Sticking Power
Apiezon H grease is a very tenacious grease conferring excellent cohesive strength. With Apiezon H grease, gone are the days of loose fitting glassware and mated joints coming loose.
“Stiction” power not only makes Apiezon H grease ideal for use with laboratory glassware, but combined with properties of high thermal conductivity, it is the perfect choice for the electronics and space industries where heat sink media require adhesion.
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. There are a growing number of applications for Apiezon H outside of the vacuum area, for example, it is used on a heatsink fan for a computer central processing unit (“CPU”).
Apiezon H grease is a relatively stiff grease which does not melt, but in fact becomes stiffer as the temperature increases. It is specifically recommended for sealing and lubrication in high temperature applications, but not for highly stressed bearings.
At the upper temperature limit: Apiezon H vs. Santovac 5GB High Vacuum Greases
Santovac® 5GB Grease has a drop point of 250°C so it will therefore operate to the same top temperature as Apiezon H (240°C).
Santovac 5GB has slightly lower vapor pressure than Apiezon H at 25°C, 4 x 10-10 Torr (Apiezon H 17 x 10-10 Torr) but these values reverse themselves at higher temperatures. The vapor pressure of Santovac 5GB rises to 1 x 10-2 Torr @ 200°C (Apiezon H, 0.8 x 10-2 Torr) and 10 x 10-2 @ 250°C Torr (Apiezon H, 5 x 10-2 Torr). Santovac 5 fluid turns into a glassy solid at +5 °C (Pour Point) so one would assume that the grease will also have the same low temperature limitations, compared to Apiezon H which can be used down to -10°C.
When it is all said and done, these two products are pretty close in properties and characteristics, that that is why both products seem to have their “fans” of users who have tried both but prefer one or the other.
Thermally Conducting:
Apiezon H 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.
