Fomblin® PFPE Lubricants for Vacuum Applications - Reliable Solutions for Extreme Conditions

Fomblin® Y grades are fully fluorinated polyether inert fluids designed for lubrication in vacuum pump systems. Fomblin® PFPE fluids consist of a blend of fluorinated polymers produced through a photochemical process starting hexafluoropropylene. Since the Fomblin® PFPE chemical chain contains only carbon, fluorine and oxygen atoms, these fluids have exceptional properties such as:

• 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

Typical Vacuum Industry Applications

• Semiconductor manufacturing equipment

• Dry and wet vacuum pumps (scroll, rotary vane, diffusion pumps)

• Analytical instruments (mass spectrometers, electron microscopes)

• Coating and thin-film deposition systems

• Space and aerospace vacuum systems

• Pharmaceutical and cleanroom environments

Key Advantages

• Zero carbon residue

• Compatible with most plastics and elastomers

• Broad operating temperature range

• Excellent lubricity under extreme pressures

• Clean, non-toxic, and odorless

Fomblin® Y LVAC Grades

Fomblin® Y LVAC grades are high-performance PFPE lubricants specially engineered for demanding vacuum applications that require outstanding chemical stability, ultra-low vapor pressure, and clean operation. These oils deliver reliable lubrication in high-vacuum and ultra-high-vacuum systems, ensuring minimal evaporation and preventing contamination of sensitive equipment. With excellent thermal resistance and long service life, Fomblin® Y LVAC lubricants are ideal for use in dry and wet vacuum pumps, semiconductor manufacturing tools, analytical instruments, and other environments where cleanliness and durability are critical.

Fomblin® Y LVAC RP Grades

Additivated Grades for Anti-Rust and Anti-Wear

Rust Preventive formulation (LVAC RP) 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.
