Apiezon H High Temperature Vacuum Grease 25g 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 organizations, including BAE Systems, the European Space Agency and NASA. Safety Data Sheet Technical Data Sheet Apiezon H Grease: High Temperature Vacuum Grease Properties 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 vapor pressure of 1.7 x 10-9 Torr at 20°C Please click the links for typical properties and vapour pressure graphs of Apiezon H Grease. Applications of Apiezon H Grease As a high temperature, low to medium vacuum grease with excellent 'stiction' power and good thermal conduction properties Apiezon H Grease is used for many diverse applications. In particular H Grease is commonly used in scientific and industrial high temperature sealing applications.Thanks to its 'stiction' power Apiezon H Grease is ideal for use with laboratory glassware; it is also favoured by the electronics and space industries where its high thermal conductivity makes it the perfect vacuum grease in situations where heat sink media requires adhesion.Apiezon H grease has been approved by NASA as a material suitable for lubricating the gold-plated threads of small variable capacitors required to operate under high vacuum from -65°C to +125°C to prevent galling.

Apiezon PFPE 501 High Temperature Vacuum Grease 100g We are pleased to announce that there is a new addition to the Apiezon range of high vacuum greases. Delivering the quality and reliability synonymous with the Apiezon brand, PFPE 501 is the perfect addition to our range. PFPE 501 is a chemically inert, high temperature and extreme pressure lubricant. With an upper operating temperature of 250°C and vapor pressure of 1.3 x 10-12 at 25°C, it is robust, versatile and can be used for sealing and lubricating under the most extreme operating conditions. This includes environments where aggressive chemicals and strong oxidizing agents are regularly used. As most Apiezon users are more familiar with hydrocarbon chemistry we’d like to provide some background on what PFPE is, and how its molecular structure can explain its physical properties. This information can be found in What is PFPE? Safety Data Sheet Technical Data Sheet Why Use Apiezon PFPE 501 Grease? PFPE based High temperature lubricant Used in oxygen-rich environments Ultra high vacuum Chemically inert Extreme pressure Wide temperature range Benefits of Apiezon PFPE 501 Grease? Extended equipment life High temperature lubricant Reduced equipment downtime Lower service costs Life-time lubrication 10 year shelf life Guaranteed Apiezon quality Expert technical support
