O-Rings & Seals
Apiezon Greases for O-Rings and Seals
For many years the Apiezon family of vacuum greases has been extensively used for o-ring and sealing applications because of their excellent properties.
All of the Apiezon greases serve to enhance the sealing performance of o-rings as well as making them easier to install and remove. Apiezon greases are silicone-free, hydrocarbon based products and are compatible with a wide range of o-ring materials including viton, silicone, nitrile (>30% nitrile content), nylon, polyurethane, polyethylene and polypropylene.
Due to their hydrocarbon formulation Apiezon greases and oils are not compatible with EPDM (ethylene propylene diene M-class rubber), EPR (ethylene propylene rubber), Butyl rubber and PVC seals.
Apiezon greases are versatile because they provide solutions for a wide range of temperatures. All Apiezon greases have excellent vapour pressure characteristics which are important for a variety of applications, including thin film deposition, as volatiles will not jeopardize the vacuum within the system or contaminate the thin film deposits.
In addition the Apiezon range offers Apiezon L, M and N greases which all have very low vapour pressures and are suitable for ultra high and high vacuum applications.
