PFPE 501 - High Vacuum Grease

Apiezon 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.

Apiezon PFPE 501 has proven to be an excellent sealant and lubricant in short path distillation, coating and semiconductor industries.

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)
