High viscosity polyalphaolefins

Today’s lubricant marketplace demands enhanced performance capabilities, improved flow at low temperatures and better durability. SpectraSyn™ Hi Vis (High Viscosity) PAO (polyalphaolefins) feature low-temperature properties, low volatility and improved thermal stability. Their high viscosity indices translate into improved flow at low temperatures and increased film thickness at high temperatures. In addition to being shear stable and hydrolytically stable, they have good compatibility with mineral oils.

Available in 40 and 100 cSt at 100°C viscosities, SpectraSyn Hi Vis PAO base stocks are particularly well-suited for industrial oils requiring high stability under extreme operating conditions. They are frequently used with lower-viscosity fluids (PAO, mineral oils) as a viscosity booster to achieve a wide range of ISO VG industrial and automotive gear oils.

Enhanced performance

Oxidative stability

Good oxidative stability is essential for applications at elevated temperatures with air contact. In our proprietary oxidative stability test, we compared a Group II mineral oil with SpectraSyn Hi Vis PAO (viscosity grades 40 and 100 cSt) base stocks. The oils included 2% antioxidant and were tested at 163°C (325°F) for 72 hours. Both SpectraSyn Hi Vis PAO grades demonstrated excellent oxidative stability, outperforming the Group II.
