PFPE Vacuum Pump Oils

TOPDA PFPE Vacuum Pump Oils are high‑performance perfluorinated polyether inert fluids composed exclusively of carbon (C), fluorine (F), and oxygen (O) atoms. They deliver outstanding chemical inertness, thermal stability, and ultra‑low vapor pressure, making them the preferred lubricating, sealing, and working fluids for vacuum pumps operating in the harshest environments.

Certifications

• EU REACH Registration
• SGS RoHS Compliant
• PFAS‑Free Tested

Key Performance Advantages

• Extreme chemical inertness: Stable in contact with oxygen, ozone, nitrogen oxides, halogens, hydrogen halides, and reactive gases
• Ultra‑low vapor pressure: Ideal for high‑vacuum and ultra‑high‑vacuum systems
• Excellent thermal stability: Wide service temperature range, low volatility, long service life  
• Non‑flammable, non‑toxic: Safe for oxygen systems, semiconductors, and precision instruments
• Full compatibility: Compatible with metals, plastics, elastomers, and most sealing materials
• Direct drop‑in replacements: Matches leading international grades for easy substitution
