Fomblin M15 High Viscosity Index PFPE Lubricant ISO VG 100
Material: PFPE (Perfluoropolyether)
Viscosity (40°C): 90.0 cSt
Viscosity Index: 329
ISO Grade: 100
Packing: 5 kg / drum
Fomblin M15 is a high-viscosity-index perfluoropolyether (PFPE) lubricant within the Fomblin M series. Produced by Syensqo, formerly Solvay, this fluid offers excellent viscosity index of 329, excellent low-temperature torque values, very good extreme pressure characteristics, and very low evaporative loss properties. It has a kinematic viscosity of 90.0 cSt at 40°C and 27.0 cSt at 100°C, classified as ISO VG 100.
Fomblin M15 provides a balanced performance profile within the M series, offering higher viscosity than M07 (38 cSt) with a viscosity index of 329 and significantly lower evaporation loss (0.8% at 149°C/22h vs 2% for M07). Its high molecular weight of 9,700 amu ensures strong film thickness and load-carrying capacity. With a pour point of -75°C and excellent chemical resistance, Fomblin M15 delivers reliable performance across a wide range of demanding industrial applications.
