Conventional Lubricants vs. Perfluoropolyether Oil

Performance Comparison	Conventional Lubricants	Perfluoropolyether Oil
Oxygen	Slowly oxidizes, forming acids or sludge	Highly resistant, does not react or ignite
High Temperature	Rapid oxidation, carbon buildup or coking, increased volatility and leakage	No carbon buildup, low volatility, minimal loss
Water or Humid Environment	Emulsifies, washed out by water	Immiscible in water
Chemicals	Corroded by acids, bases, or organic solvents	Chemically stable
Contact with Components	Can corrode seals, lubricant leakage, equipment damage	Broad material compatibility, non-corrosive
