Apiezon PFPE 501 vacuum grease is a chemically inert, high temperature 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.

Apiezon PFPE 501 is also certified H1 food grade by NSF international, who are the global independent body that certify food service equipment and supplies for use to the industry. Having the H1 classification confirms that Apiezon PFPE 501 can be used safely in the food production chain where incidental food contact may occur. To achieve this level of accreditation with NSF, the content in the final product must not exceed 10ppm (parts per million). Find out more here.
