Uniflor™- PFPEs
Nye’s Uniflor™ PPFEs are the most thermo-oxidatively stable lubricants available today. Unlike any other brand of fluorinated lubricants, the Uniflor™ line utilizes every available PFPE oil to create a diverse product line and achieve optimal performance under a variety of operating conditions. Uniflor™ products can withstand temperatures from –90 °C to +250 °C, and even higher excursions.
What are PFPE's?
Perfluoropolyether's (PFPEs) are fluorinated synthetic fluids that are well suited for the demanding environments or applications where chemical interaction between materials may pose an issue. While all PFPEs are composed of carbon, fluorine, and oxygen, the molecular structure of each PFPE fluid varies depending on the base materials and polymerization processes used by PFPE manufacturers. These structural differences will affect the fluid’s pour point, volatility, viscosity, and viscosity index — all critical factors in lubricant formulation. Some PFPE oils, for example, have a pour point of only -20°C, while others offer pour points as low as -90°C. Similarly, some PFPE oils offer better wear resistance and vapor pressure properties than others.
Advantages of Uniflor™ PPFEs
- Wide temperature performance
- Excellent oxidative and thermal stability
- Resistant to aggressive chemicals and solvents
- Nonflammable and chemically inert
- Low volatility and vapor pressure
- Excellent plastic and elastomer compatibility
Uniflor™ Lubricants For Your Industry
Below is a selection of our most commonly reccomended Uniflor™ products by industry.
To produce more powerful and efficient vehicles, automotive lubricants must be compatible with a range of materials while withstanding high temperatures. Uniflor™ lubricants are compatible with most plastics and elastomers and were designed to withstand harsh chemicals like brake fluid and exhaust fumes. PFPE’s high temperature stability helps protect against wear and arcing conditions to extend the service life.

Primary flight controls need to activate properly as desired by the pilot when the aircraft is in flight. Lubricating airframe components with a grease designed for high speed, wide temperature conditions will ensure proper long-term function and maintenance-free operation of these critical flight systems. Likewise, engine components, including the lubricant, must withstand a wide range of temperatures, be compatible with aviation fuels and resist corrosive fuel system vapors.

2 | General Purpose Use |
Thrust vectoring allows jets to direct engine power for maximum maneuverability, short take offs and landings. The actuator physically redirects jet propulsion, requiring a lubricant that survives the engine’s hot exhaust. Uniflor™ greases are well suited for defense applications as they resist hydrocarbon fuel and liquid oxygen.
