Syensqo (Solvay Specialty Polymers) Fomblin® Y LVAC 25/6E Perfluoropolyether
Categories: Fluid; Lubricant; Perfluoropolyether (PFPE)

Material Notes: Fomblin® Y PFPE perfluoropolyether fluids have the following unique features:
- Low vapor pressure
- Chemical inertness
- High thermal stability
- Good lubricant properties
- No flash or fire point
- Non-toxicity
- Excellent compatibility with metals, plastics, elastomers
- Good aqueous and non-aqueous solvent resistance
- High dielectric properties
- Low surface tension
- Good radiation stability
- Environmentally acceptable
Rust Preventive formulation (LVAC E) was studied to reduce or prevent rusting when huge amount of water vapors has to be pumped or when metal surfaces of the pump are exposed to moisture. An optimum concentration of additive in Fomblin® Y LVAC grades was studied to provide protection against rust and at the same time to guarantee the physical properties and the vacuum performance of the grade.

Features: Chemical Resistant; High Density; High Heat Resistance
