Fomblin Y45 Medium High Viscosity PFPE Lubricant ISO VG 150
Material: PFPE (Perfluoropolyether)
Viscosity (40°C): 147 cSt
Viscosity Index: 117
ISO Grade: 150
Packing: 5 kg / drum
Fomblin Y45 is a medium-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 147 cSt at 40°C and 16.0 cSt at 100°C, classified as ISO VG 150 with a viscosity index of 117.
Fomblin Y45 provides a balanced performance profile within the Y series, offering higher viscosity than Y25 (80 cSt) while maintaining lower evaporation loss than Y25 (0.70% vs 2.0% at 149°C/22h). Its high molecular weight (4,100 amu) ensures strong film thickness and load-carrying capacity for medium to heavy-duty applications. With a pour point of -30°C and excellent chemical resistance, Fomblin Y45 delivers reliable performance across a wide range of industrial applications.
