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
