Solvay Fomblin YLVAC 25/6

Core Performance and Features

• Extreme Chemical Inertness: Exhibits extremely high resistance to acids, alkalis, halogens (such as chlorine), and strong oxidizing gases, and will never react with them.
• Excellent Thermal Stability: Does not decompose or coke under extreme high-temperature environments, ensuring long-term stable operation of the vacuum pump.
• High Vacuum Guarantee: Possesses extremely low vapor pressure (approximately 6 × 10⁻⁸ Torr) and extremely low oil backflow rate, preventing volatile matter contamination of the vacuum system.
• Extremely High Safety: No flash point or ignition point; will never burn or explode upon contact with high concentrations of oxygen or explosive gases.

• Excellent Lubrication Protection: Viscosity grade approximately ISO VG 220, providing excellent wear resistance and sealing protection for rotary vane pumps, Roots pumps, etc.

  Main application scenarios

• Semiconductor and electronic manufacturing: Suitable for plasma etching (Dry Etching), chemical vapor deposition (CVD) and other processes that generate corrosive gases.
• Chemical and pharmaceutical industry: Chemical processing vacuum pumps used to remove highly corrosive media such as strong acids, strong bases, organic solvents or crude biofuels.
• High Purity Oxygen Systems: Safe lubricating explosion-proof oil when pumping high concentration or pure oxygen vacuum systems.

• Mainstream vacuum pump matching: often designated or recommended by internationally renowned vacuum brands such as Edwards for use in harsh working conditions.
