Fomblin HV5 – –80℃ to 290℃ High Thermal Stability PFPE Lubricant
Material: PFPE (Perfluoropolyether)
Operating Range: -80℃ to 260℃ (290℃ short-term)
Chemical Resistance: Acids, Bases, Solvents, Halogens
Flammability: Non-flammable
Packing: 5 KG / 20 KG / drum
Fomblin HV5 is a high-thermal-stability perfluoropolyether (PFPE) lubricant within the Fomblin PFPE series. Produced by Syensqo, formerly Solvay, this inert, dielectric and non‑flammable fluid has a typical operating temperature range of -80 °C to 260 °C, with short-term capability up to 290 °C. It does not coke or decompose at high temperatures and remains fluid at low temperatures, making it an ideal choice for demanding lubrication applications.
Fomblin HV5 exhibits unmatched chemical and solvent resistance. It is non-reactive with metals, plastics, elastomers and rubber, and is inert to liquid and gaseous oxygen. With excellent radiation hardness and non-flammability, Fomblin HV5 is engineered for applications where heat, chemicals, solvents, corrosion, toxicity, flammability, and service life present lubrication problems. Conventional hydraulic fluids start degrading at 220 °C, while Fomblin PFPE oils are stable up to 290 °C.

Core Advantages of Fomblin HV5 PFPE Lubricant
- Wide operating temperature range from -80 °C to 290 °C — no coking at high temperatures, remains fluid at low temperatures
- Unmatched chemical and solvent resistance — resistant to strong acids, bases, oxidizers, organic solvents, halogens, ozone, and liquid oxygen
- Non-reactive with materials — compatible with metals, plastics, elastomers and rubber; no swelling or corrosion
- Non-flammable and safe — non-flammable, non-self-igniting, non-toxic, suitable for oxygen systems and medical/food applications
- Extremely low vapor pressure — minimal evaporation, long service life, ideal for high and ultra-high vacuum applications
- Excellent radiation resistance — resistant to gamma rays and electron beams, does not age or degrade with long-term use
- Superior lubricity and long service life — low friction coefficient, wear resistance, extended maintenance intervals
- High dielectric strength — non-conductive, suitable for electronic insulation, heat dissipation, and sealing applications
Main Applications
- Semiconductor & Electronics — vacuum pump oil, chamber sealing, wafer cleaning, lithography equipment lubrication
- Aerospace & Defense — liquid oxygen systems, rocket engine seals, satellite bearings; used in NASA and ESA space programs for over 25 years
- Chemical & Nuclear — valves, pumps, high-temperature pipe sealing for corrosive media, radiation-resistant applications
- Medical & Food — sterile environments, high-temperature sterilization equipment, non-migrating lubrication
- Oil & Gas — hydraulic fluids for extreme temperatures up to 260 °C and high pressures (30,000 psi)
- Automotive — demanding high-performance lubrication applications
