Vacuum Greases - Hydrocarbon
The Apiezon family of hydrocarbon high vacuum greases have been serving the market for many years and are highly regarded for their quality, consistency and excellent performance in vacuum applications.
These Apiezon greases are hydrocarbon based, silicone-free and highly resistant to creep, the undesirable phenomenon associated with silicone-based products. Using Apiezon reduces the chance of grease travelling away from the area of application and contaminating adjacent surfaces. In addition the ultra high vacuum grease ensures ultimate cleanliness and low outgassing without contaminating vacuum systems.
At M&I Materials we manufacture 7 different hydrocarbon high vacuum greases:
Customers using Apiezon high vacuum greases include NASA, Boeing, Lockheed Martin, Honeywell, leading Universities and research organisations. Apiezon greases are specified for use in hundreds of different products and research programmes.
Vacuum Greases - Perfluoropolyether
Apiezon PFPE 501 grease is a long chain polymer which consists of carbon, oxygen and fluorine atoms.
With an upper operating temperature of 250°C and vapour 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 oxidising agents are regularly used.
