- Density: 1.88 g/cc at 20℃, 1.73 g/cc at 100℃.
- Kinematic Viscosity: 60 cSt at 20℃, 4.1 cSt at 100℃.
- Pour Point: -60℃.
- Flash Point: No flash point; classified as a non-flammable liquid.
- Vapor Pressure: Extremely low at 20℃, only 5.33×10⁻¹⁰ bar. This contributes to its stability in vacuum systems, minimizing oil vapor contamination of the vacuum environment.

- Chemical Stability: Exhibits high chemical inertness, does not react with most metals, plastics, rubbers, etc. Suitable for the lubrication and sealing of components made of various materials, effectively preventing chemical corrosion and material degradation.
- High-Temperature Resistance: Can operate stably for extended periods within a temperature range of -67℃ to 120℃. In some situations, it can withstand even higher temperatures for short durations, maintaining good lubricity and viscosity stability in high-temperature environments, with minimal oxidation and decomposition.
- Low Volatility: The extremely low vapor pressure results in minimal evaporation in vacuum environments, effectively reducing oil vapor contamination of vacuum systems, sustaining high vacuum levels, and enhancing system stability and reliability.
- Fire Resistance: Non-combustible; will not burn or explode when exposed to high temperatures, open flames, or other ignition sources, significantly lowering safety hazards during usage, particularly suited for applications with stringent fire safety requirements.
- Excellent Lubricity: Forms a uniform and robust lubricating film on various friction surfaces, effectively reducing the coefficient of friction, minimizing wear, and boosting operating effectiveness and the longevity of machinery. It can furnish trustworthy lubrication, even under harsh circumstances such as high vacuum, extreme temperatures, and high velocities.
- Recyclability: Recyclable, aiding in the reduction of resource depletion and environmental impact.

- Vacuum Systems: Widely utilized in various vacuum pumps, such as rotary pumps, diffusion pumps, and molecular pumps, to effectively enhance pumping speed and ultimate vacuum, prolong pump operational life, and diminish maintenance frequency. Suited for vacuum processes, for example, semiconductor fabrication, electron beam evaporation, vacuum coating, and vacuum heat treatment.
- Aerospace: Applied for lubrication and sealing in various precision instruments, meters, and engine parts in the aerospace field, ensuring regular operation of machinery in severe conditions like extreme temperatures, high vacuum, and strong radiation.
- Automotive Industry: Can be employed in certain critical automotive engine components, such as turbocharger systems and valve lifters, providing high-temperature lubrication and sealing. Also applicable to compressors and vacuum pumps in automotive air conditioning systems, ensuring reliable operation under various working conditions.
