P-204 NSF H1 PFPE Synthetic Lubricating Oil for High-Temperature Bearings and Oxygen-Compatible

-Type: PFPE lubricating oil, NSF H1 PFPE food-grade bearing oil, high temperature bearings oil, nonflammable oxygen-compatible PFPE oil, chemical inert synthetic oil for metals and plastics.

- P-204 is a pure PFPE synthetic oil composed solely of carbon, oxygen, and fluorine atoms, fully saturated and devoid of reactive functional groups, ensuring exceptional chemical inertness.
- Additive-free formulation: Prevents reactions or swelling with plastics (PTFE), elastomers (fluororubber), and metals (stainless steel/alloys), ensuring material compatibility.
- Safety Certification: Certified by NSF H1 for incidental contact with food processing equipment.

1. Core Physical Parameters
    - Viscosity at 40°C: 243 cSt (ASTM D445)
    - Viscosity at 100°C: 25 cSt (ASTM D445)
    - Operating Temperature Range: -36°C to 260°C (continuous), peak at 270°C (short-term)
    - Viscosity Index: 134 (ISO 2909)
    - Density: 1.94 g/cm³
    - Volatility: Extremely low (no VOCs)

2. High Temperature and Chemical Stability
    - Oxidation Resistance: Remains stable at continuous high temperatures of 260°C and can tolerate short-term peaks of 270°C, far exceeding mineral oil limits.
    - Chemical Inertness: Resists strong acids (e.g., fuming nitric acid), strong bases, steam, chlorine gas, oxygen, and other corrosive media without reaction or degradation.
    - Non-flammability: Lacks flash and autoignition points; passes liquid oxygen impact test (ASTM D1743), making it suitable for aerospace oxygen-rich environments.
3. Long-lasting Lubrication and Low Maintenance
    - Low volatility and high adhesion reduce the frequency of reapplication, prolonging equipment lifespan (e.g., lifetime-sealed bearings).
    - Radiation resistance up to 10⁷ rads, suitable for nuclear industry applications.
4. Safety and Environmental Compatibility
    - Non-toxic and free of volatile organic compounds (VOCs), meeting environmental and food-grade standards.

- Aerospace: Liquid oxygen valves, fuel pump bearings, spacesuit seals (oxygen-resistant environments).
- High-Temperature Industries: Furnace conveyor chains, hot air blower bearings, SMT lead-free reflow soldering chains (270°C peak tolerance).
- Chemical Equipment: Reactor agitator bearings, seals for corrosive media valves (acid/base resistance).
- Food Processing: Filling line bearings, conveyor belt joints (NSF H1-certified scenarios).
- Semiconductor Manufacturing: Vacuum pump oil, etching equipment gears (low-volatility contamination resistance).

1. Cleaning Requirements: Thoroughly remove existing grease (e.g., anti-rust oil) from components before use to prevent performance degradation due to mixing.
2. Storage Recommendations: Unlimited shelf life when unopened; if oil layer separation occurs, stir to restore consistency.
3. Prohibition of Mixing: PFPE oil must not be mixed with mineral oils, silicone oils, or others, as this may lead to product failure.

4. Selection Recommendations: XYC 204 strikes a balance between medium-to-high viscosity, ultra-high temperature resistance, and general-purpose usability, suitable for continuous operation below 260°C. For higher temperatures (288°C+) or lower viscosity needs, consider other models from the same series.
