ExxonMobil SpectraSyn™ 40 Polyalphaolefin (PAO) Fluid
Categories:	Fluid; Lubricant; Polyalphaolefin (PAO)
Material Notes:	Product Description: SpectraSyn™ High Viscosity Polyalphaolefin (PAO) basestocks feature low temperature properties (pour point and viscosity), low volatility, and improved thermal stability. SpectraSyn™ High Viscosity (PAO) products have high viscosity indices translate into improved flow at low temperatures and increased film thickness at high temperatures. SpectraSyn™ High Viscosity PAO basestocks are particularly suited for industrial oils requiring high stability under extreme operating conditions. SpectraSyn™ High Viscosity PAO products are frequently used in conjunction with lower viscosity fluids (PAO, mineral oils) as a viscosity booster to achieve a wide range of ISO VG industrial and automotive gear oils. Appearance: Bright & Clear Availability: Africa & Middle East, Asia Pacific, Central America, Europe, North America and South America Information provided by ExxonMobil
