SpectraSyn,Ñ¢ 40 is a high viscosity polyalphaolefin (PAO) base stock designed for industrial applications requiring enhanced stability under extreme operating conditions. It features low temperature properties, including a pour point of -33¬8F (-36¬8C) and a viscosity index of 147, which contribute to improved flow at low temperatures and increased film thickness at high temperatures. The product exhibits low volatility and excellent thermal stability, making it suitable for use in conjunction with lower viscosity fluids to achieve a wide range of ISO VG industrial and automotive gear oils. Key characteristics include a kinematic viscosity of 39.0 cSt at 212¬8F (100¬8C) and 396 cSt at 104¬8F (40¬8C), along with a flash point of 538¬8F (281¬8C) and a total acid number of less than 0.10 mg KOH/g. SpectraSyn,Ñ¢ 40 is available globally, including regions such as North America, Europe, and Asia Pacific.
SpectraSyn™ Hi Vis PAO is used to increase base stock viscosity and upgrade lubricant quality with blend components especially suited for industrial oils requiring high stability under harsh operating conditions.
