Information
Krytox™ Aerospace Grade Oils & Greases (143 Series / 240 Series / 250 Series / 283 Series)
Overview
Krytox™ Performance Lubricants are aerospace-grade synthetic lubricants based on perfluoropolyether (PFPE) chemistry. Manufactured by :contentReference[oaicite:0]{index=0}, these oils and greases are designed for extreme environments where conventional lubricants fail. They are chemically inert, non-flammable, oxygen-safe, and capable of continuous operation at high temperatures up to ~260°C with short-term peaks to ~270°C.
Key Technical Characteristics
- Base Chemistry: Perfluoropolyether (PFPE)
- Temperature Range: approx. -70°C to +260°C (depending on grade)
- Peak Temperature Resistance: up to ~270°C short-term
- Flash Point: Non-flammable
- Chemical Resistance: Inert to most acids, alkalis, solvents, fuels
- Oxygen Compatibility: Safe for oxygen service
- Material Compatibility: Safe on metals, plastics, and elastomers
- Volatility: Extremely low vapor pressure across aerospace grades
Performance Highlights
- Ultra-low volatility for vacuum and aerospace environments
- Stable viscosity across wide temperature ranges
- No oxidation degradation under normal service conditions
- Long service intervals with minimal re-lubrication required
- High dielectric and chemical stability
Typical Aerospace Applications
- Aircraft bearings and actuators
- Spacecraft mechanisms and satellite components
- Oxygen system valves and seals
- Jet engine accessory systems
- Precision instruments and sensors
- Semiconductor manufacturing equipment
Material & Chemical Structure
Krytox™ PFPE oils consist of fully fluorinated polymer chains containing only carbon, oxygen, and fluorine, resulting in exceptional inertness and thermal stability. The PTFE thickeners used in greases provide mechanical stability and extremely low friction characteristics.
Advantages
- Non-flammable under all conditions
- Safe for oxygen-rich environments
- No reaction with plastics, elastomers, or metals
- Extremely long service life compared to hydrocarbon oils
- High resistance to radiation, oxidation, and chemical attack
Limitations / Handling Notes
- Higher cost compared to conventional lubricants
- Requires careful selection of grade based on viscosity and load
- Contamination with other oils can reduce performance
