Apiezon PFPE 501 Grease

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

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.

Apiezon PFPE 501 has proven to be an excellent sealant and lubricant, particularly in laboratory applications, such as in short path distillation.

Being certified as NSF H1 food grade means that it can be used with machinery such as vacuum pumps, mixers, conveyor belts, and other applications associated with:

Blending

Bottling

Brewing

Cooking

Cutting

Handling

Peeling

Slicing

Due to its inert chemical nature, this grease is recommended for use under extreme conditions such as in the presence of aggressive chemicals, strong oxidizers or high oxygen levels.
