Introduction to Perfluoropolyether (PFPE)

Perfluoropolyether (PFPE) oils are chemically inert, capable of handling extreme temperatures and also hazardous operating environments, PFPEs are resistant against fuels, solvents and chemicals, examples such as sulphuric acid and sodium hydroxide. PFPEs are composed entirely of carbon, fluorine and oxygen. PFPE summary:

Temperature range of -90 to 250°C
Low vapour pressure
Non-flammable
Excellent plastic compatibility
High cost and high density
Not good at dealing with heavy loads
Poor solubility of additives, so not a great range of additive options
Resistant to low levels of radiation
Viscosity Index 100 to 350

Keep in mind that if a PFPE is used as the base oil for a grease, the thickener and additives also used in the formula will have an influence on the final characteristics and performance of the finished grease/lubricant.

This article is only intended as a basic introduction into PFPE oils/fluids, there are different types of PFPE all of which have their particular characteristics.

Electrically charged bearing wear test with non-conductive and conductive grease

Our new video simulates the challenges faced with a bearing static discharge application. In the test a bearing is electrically charged; when a bearing is lubricated with a non-conductive grease, static discharge is not only a safety concern but wear and pitting occurs at a much increased rate when compared…
