Apiezon PFPE 5010 Grease, CAS #69991-67-9 and CAS#9002-84-0
The Apiezon family of high vacuum hydrocarbon greases are known the world over for their high quality, consistency and excellent compatibility for high vacuum applications. Now Apiezon introduces 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.
Apiezon 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.
Advantages of using PFPE 501:
- Robust - Chemical inertness and oxidation stability make PFPE 501 ideal under the most extreme operating conditions.
- Safe & Reliable - Non-toxic, nonflammable and maintains lubricity and thermal stability up to 250°C.
- Extends Service Life – Branched PFPE structure and double-density provides film-forming and superior load-carrying capability.
- Versatile - Used in a wide range of applications including bearings, valves, gears, threads, o-rings and seals.
Apiezon PFPE 501 is compatible with all types of material including plastics, metals, ceramics, polymers, elastomers, ethers, alcohols and hydrocarbons. At elevated temperatures it is recommended to avoid contact with Lewis acid catalysts such as aluminum chloride, boron trifluoride, titanium, tetrachloride and newly exposed rubbing surfaces of aluminum, magnesium or titanium alloys.
PFPE 501 is compatible with all chemicals, corrosives and solvents except those with a perfluorinated base.
Wipe off excess grease with a lint-free cloth. Residual grease can be removed using a perfluorinated solvent. For stringent cleanliness a further stage using acetone is recommended.

Ultra High Vacuum:
The extremely low vapor pressure characteristics of PFPE 501 (as demonstrated in the graph below) ensure the grease can be used with confidence under ultra high vacuum conditions.
The shelf life of Apiezon PFPE 501 is four years from date of manufacture, providing the product is in the original unopened packaging and has been stored at ambient (10 to 30°C) temperature.
