Choose Fomblin Y LVAC Grade 25/6 for:

Rotary pumps- sealing & lubricant fluid
Roots pumps – lubrication

Fomblin® Y grades are perfluorinated polyether inert fluids for use as lubricants in vacuum pumps. Fomblin® PFPE fluids are a mixture of fluorinated polymers obtained by a photochemical process that begins with 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
