Apiezon PFPE 501

By APIEZON

Apiezon PFPE 501 from M&I Materials Ltd is a high temperature vacuum grease that is the best choice when running short path distillation systems that require a high-temperature seal. This is because PFPE 501 is chemically inert, and offers effective sealing properties under extreme vacuum and temperature conditions. With an upper operating temperature of 250°C and vapour pressure of 1.3 x 10 12 at 25°C, PFPE 501 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. High quality grease such as Apiezon PFPE 501 creates a tighter seal, protects your glassware and prevents pieces of expensive glass from getting stuck together. We know that Apiezon PFPE 501 has been used extensively in short path distillation systems. Used correctly our customers and our own laboratory tests report the grease is easy to apply and remove, does not creep, is not prone to leaks, can safely be used to temperatures up to 250ºC and lasts longer than other brands. The inertness of PFPE 501 allows adjacent molecules to pass by a thin layer without any interaction. This leads to reduced contamination in your system, as well as the compatibility of the grease with many types of materials.
