Fomblin Y15 Low Viscosity PFPE Lubricant ISO VG 68
Material: PFPE (Perfluoropolyether)
Viscosity (40°C): 13.0 cSt
Viscosity Index: 100
ISO Grade: 68
Packing: 5 kg / drum
Fomblin Y15 is a low-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 13.0 cSt at 40°C and 2.7 cSt at 100°C, classified as ISO VG 68 with a viscosity index of 100.
Fomblin Y15 is the lowest viscosity grade in the Fomblin Y series, making it particularly suitable for high-speed applications requiring low fluid friction and efficient heat dissipation. Its excellent EP and wear characteristics (Four Ball Wear Test 0.66 mm at 75°C, 1200 rpm, 40 kg) provide reliable protection for precision mechanical systems. The fluid features a pour point of -45°C, ensuring good low-temperature flow performance.
