Automotive Production Equipment

Fomblin® PFPE is the ideal lubrication solution for the automotive industry, meeting lubrication challenges by providing the best possible performance for demanding applications. It is used as neat oil, formulated into greases, or deposited on the part through suitable carriers.

  • Oxidation and thermal stability
  • Chemical resistance to most automotive solvents, oils, fluids and gases 
  • The broadest operating temperature range of any lubricant in its class, from -85°C to +290°C.

Contact Lubrication

A lubricant can extend the life of electrical switches and connectors. Some are designed for low electrical currents to send signals to relays and computers. Others are designed to carry high electrical loads to starters, headlights and turn signals. More and more switches are expected to do both and to perform across a wide temperature range.

Fomblin® PFPE lubricants are characterized by their excellent electrical properties and extremely wide operating temperature range. They are used to lubricate automotive connectors where the low temperature (-40°C) specifications are especially challenging.

Fomblin® PFPE oils have low electrical resistance in thin films without affecting the resistance between adjacent conductors or components.

Vacuum Pump Lubrication

Fomblin® PFPE fluorinated fluids are:

  • Thermally stable
  • Chemically inert 
  • Non-flammable 
  • Non-toxic


They are compatible with: 

  • Metals 
  • Hydrogenated polymers
  • Oxygen 
  • Aggressive gases, even at very high temperatures. 


They possess: 

  • Low vapor pressure 
  • Good dielectrical properties.

When critical applications have to be addressed where aggressive chemical environments, high temperatures or wide working temperature ranges are involved, they represent the lubricants of choice. Fomblin® PFPE Y LVAC and Y HVAC grades are ideal for use in vacuum pumps as sealing and working fluids especially in those systems exposed to aggressive gases. Fomblin® PFPE Y HVAC combines narrow molecular weight range and controlled viscosity with an extremely low vapor pressure.

Chemical inertness, thermal stability above 290°C and the potential to provide anti-rust and anti-wear additivation make the Fomblin® VAC product line ideal for lubrication of vacuum pumps in harsh environments such as semiconductor processing.

Magnetic Recording Media Lubrication

Fomblin® PFPE Z derivatives are well know lubricants for the Magnetic Recording Media industry. They are used as top lubricant on the HD drive surface to prevent damaged on the disk surface.

Food Service Equipment
