Fomblin YU700 High Viscosity PFPE Lubricant ISO VG 220
Material: PFPE (Perfluoropolyether)
Viscosity (40°C): 214 cSt
Viscosity Index: 124
ISO Grade: 220
Packing: 5 kg / drum
Fomblin YU700 is a high-viscosity perfluoropolyether (PFPE) lubricant within the Fomblin Y series. Produced by Syensqo, formerly Solvay, this fluid offers excellent high-temperature stability, good low-temperature properties, very good extreme pressure and wear characteristics, and low evaporative loss. It has a kinematic viscosity of 214 cSt at 40°C and 22.0 cSt at 100°C, classified as ISO VG 220 with a viscosity index of 124.
Fomblin YU700 provides a balanced performance profile within the Y series, offering higher viscosity than Y45 (147 cSt) while maintaining a viscosity index of 124 for stable performance across temperature variations. Its high molecular weight (5,000 amu) ensures strong film thickness and load-carrying capacity for heavy-duty applications. With a pour point of -27°C and excellent chemical resistance, Fomblin YU700 delivers reliable performance in demanding industrial environments.
