Fomblin YR1800 Ultra High Viscosity PFPE Lubricant ISO VG 460
Material: PFPE (Perfluoropolyether)
Viscosity (40°C): 510 cSt
Viscosity Index: 148
ISO Grade: 460
Packing: 5 kg / drum
Fomblin YR1800 is the highest-viscosity grade in the Fomblin YR series, delivering an ultra-high viscosity of 510 cSt at 40°C with a viscosity index of 148. Produced by Syensqo, formerly Solvay, this perfluoropolyether (PFPE) lubricant offers exceptional film thickness, outstanding load-carrying capacity, and excellent chemical resistance for the most demanding heavy-duty applications. It is classified as ISO VG 460.
With the highest molecular weight in the YR series at 7,300 amu and an extremely low evaporation loss of only 0.50% at 204°C/22h, Fomblin YR1800 provides maximum protection for extreme load bearings, heavy-duty gearboxes, and industrial equipment operating under severe conditions. Its high density of 1.92 g/cm³ and pour point of -20°C ensure reliable performance across a wide range of demanding applications.
