APIEZON PFPE 501 High Temp Low Vapor Vacuum Lube Grease 100g

Apiezon PFPE 501 vacuum grease 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.
