Vacuum Grease - PFPE

Vacuum Grease - PFPE

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 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. 

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?
