XYC 202 Oil Universal Perfluoropolyether Lubricating Oil 1KG

- Type: Perfluoropolyether lubricating oil, high temperature oil, universal oil, chemical inert oil.

- Chemical Composition:
XYC 202 is a perfluoropolyether (PFPE, also referred to as PFAE or PFPAE) lubricant with a molecular structure comprising only carbon, oxygen, and fluorine atoms, fully saturated and devoid of reactive groups.
    - Elemental Weight Composition: Carbon 21.6%, Oxygen 9.4%, Fluorine 69.0%.
    - Free of additives, ensuring high chemical inertness, ideal for applications involving exposure to highly corrosive media.

- Physical Properties:
    - 40°C Kinematic Viscosity: 440 cSt (ASTM D445).
    - 100°C Kinematic Viscosity: 42 cSt (ASTM D445).
    - Pour Point: -30°C (ASTM D97).
    - Density: 1.9 g/cm³ at ambient temperature.
    - Viscosity Index: 155 (ISO 2909).
    - Operating Temperature Range: -70°C to 288°C (continuous use).
    - Intermittent Peak Temperature: Up to 344°C.

- Stability in Extreme Conditions:
    - High-temperature oxidation resistance: Capable of enduring prolonged exposure to 288°C without combustion, remaining stable even at 554°C in oxygen-rich environments.
    - Chemical inertness: Resistant to aggressive substances such as fuming nitric acid, strong alkalis, chlorine gas, and hydrogen peroxide, without decomposition or swelling.
    - Low volatility: Exhibits minimal evaporation loss, making it suitable for vacuum environments (e.g., semiconductor manufacturing).
- Safety and Compatibility:
    - Non-flammability: Passes ASTM tests; does not ignite at 649°C and complies with liquid oxygen impact testing.
    - Material compatibility: Long-term coexistence with metals (steel, alloys), plastics (PTFE), and elastomers (O-rings) without causing corrosion or swelling.
    - Environmental compliance: Non-toxic, free from volatile organic compounds (VOC), and certified for NSF H1 food-grade incidental contact (specific models).
- Mechanical Properties:
    - Low friction coefficient with excellent wear resistance (validated by four-ball wear testing).
    - Radiation resistance up to 10⁷ rads, enabling applications in nuclear industry settings.

- Chemical and Energy Sector: Valve sealing (chlorine/oxygen systems), reactor stirrer bearings, petrochemical pump lubrication.
- Aerospace Industry: Spacesuit seals, liquid oxygen valves, fuel pump bearings.
- Semiconductor Manufacturing: Vacuum pump oil, etching equipment gear lubrication (low-volatility contamination).
- High-Temperature Industries: Furnace conveyor chains, hot air blower bearings (screw rods for width adjustment).
- Specialized Environments: High-temperature automotive engine components, nuclear power plant equipment lubrication.
