ISO Grade: 220
Packing: 5 kg / drum
Fomblin W500 is a high-purity perfluoropolyether (PFPE) lubricant from the Fomblin W series, produced by Syensqo (formerly Solvay). This fluid features ISO VG 220 viscosity grade, low evaporation loss (0.1% at 149°C/22h), excellent chemical resistance, and a wide operating temperature range. With a molecular weight of 7,200 amu and viscosity index of 209, Fomblin W500 delivers reliable performance across demanding industrial, aerospace, and semiconductor applications.
Fomblin W500 offers an exceptional balance of high purity and low volatility, making it ideal for applications requiring minimal outgassing and extended service life. Its pour point of -46°C ensures reliable cold-start performance, while its chemical inertness provides protection against aggressive chemicals, chlorine, acids, and alkalis. With surface tension of 23 dyne/cm and four ball wear test result of 0.9 mm, this grade provides excellent film strength and anti-wear protection.
