Fomblin YL VAC grades are perfluorinated polyether inert fluids for use as lubricants in vacuum pumps.
Fomblin fluids are a mixture of fluorinated polymers obtained by a photochemical process that begins with hexafluoropropylene.
Since the Fomblin chemical chain contains only carbon, fluorine and oxygen atoms, these fluids have exceptiional properties such as:
- Low Vapor pressure
- Chemical Inertness
- High Thermal Stability
- Good lubricant properties
- No flash or fire point
- Low toxicity
- Excellent compatability with metals, plastics, elastomers
- Good aqeous and non-aqueous solvent resistance
- High dialectric properties
- Low surface tension
- Good radiation Stability
- Environmental acceptance
