P-240 AA Low Viscosity PFPE Aviation Grease Oxygen-Safe and Stable for Aerospace and Semiconductor

Base stocks: synthetic perfluoropolyether

Type of thickener: polytetrafluoroethylene

Tags: low viscosity PFPE grease, aviation grease, perfluoropolyether grease, oxygen safe lubricant.

- Fundamental Traits: Exhibits a white, paste-like consistency; chemically inert and non-flammable. Composed of fluorine, carbon, and oxygen atoms, demonstrating sound compatibility with diverse metals, elastomers, plastics, coatings, and analogous materials.
- Viscosity Profile: Viscosity measures 88 cSt at 20°C, decreasing to 35 cSt at 38°C, and further to 5.4 cSt at 99°C. This product presents the lowest viscosity within the 240 series, rendering it appropriate for applications demanding low-viscosity lubricants.
- Thermal Gradient: Operable within a temperature span of -51°C to 177°C. Maintains consistent lubricating properties under extreme temperature conditions, fulfilling the stringent high and low temperature requirements of sectors such as aerospace.
- Constancy and Longevity: Displays exceptional thermal and oxidative stability, resisting degradation and volatilization at elevated temperatures, thereby ensuring prolonged lubrication performance. Oxidation stability tests at 99°C for 600 hours revealed a pressure drop of 0 psig. Base oil evaporation loss at 149°C over 22 hours was quantified at 15%.
- Assurance: Successfully passed the Liquid Oxygen Impact Test (ASTM D2512, NASA MSFC 106B), affirming its safe utilization in oxygen-rich environments, including critical components such as oxygen systems within the aerospace domain.

- Aerospace: Extensively implemented in aircraft bearings, seals, valves, O-rings, threaded interfaces, and oxygen apparatus. Delivers dependable lubrication and sealing within the severe temperature and high-vacuum conditions encountered at high altitudes, ensuring flight integrity.
- Supplementary Sectors: Also applicable in industrial areas with elevated lubrication stringency and harsh operational parameters, such as semiconductor fabrication and advanced electronics manufacturing. Can be adopted to satisfy the requirements for diminished friction, amplified steadiness, and resistance to corrosion.
