Perfluoropolyether (PFPE Oil) | CAS 60164-51-4
PFPE High Temp Lubricating Oils (S‑Grades) are fully inert Perfluoropolyether (PFPE Oil) fluids (CAS 60164-51-4), specially formulated for reliable lubrication in extreme high temperature and ultra‑high vacuum environments where conventional lubricants cannot perform.
These high‑performance Perfluoropolyether fluids deliver exceptional thermal stability, ultra‑low volatility, high viscosity index, and long‑term lubrication under the harshest operating conditions.
Key Features
- Extreme thermal stability up to 325°C
- Ultra‑low evaporation loss for long service life
- High viscosity index for consistent performance across temperatures
- Chemically inert, non‑flammable, non‑toxic
- Excellent lubricity in ultra‑high vacuum systemsvacuum pumps
- Full compatibility with metals, plastics, and elastomers
- CAS registered: PFPE Oil CAS 60164-51-4
