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
