The high thermal efficiency and desirable dielectric properties throughout the life of a fluid makes improved LVLV PAO base stocks well suited for direct cooling applications. This improves thermal management of e-motor and electronics in EV and can help with immersion cooling for batteries. With having lower viscosity, they can also provide enhanced thermal management in the system compared to conventional PAO or Gr II/III base stocks. LVLV PAO base stocks also have excellent oxidative stability, which can help with the lifelong operation of the oil.
One of the most important characteristics of next- generation LVLV PAO base stocks is providing lower traction coefficient/torque loss, resulting in improved energy efficiency, and extending the range of EVs.
Conclusion
Over the last decade, the demand for PAO base stocks has been growing due to extended drain intervals, better temperature performance, increased durability, and improved energy efficiency that they offer. But to meet increasingly demanding OEM specifications, engine oils and EV driveline fluids are evolving to lower viscosity while still delivering the same performance levels and wear protection as their predecessors.
As formulators develop new lubricants to meet these demands and reduce emissions, improved LVLV PAO base stocks offer several distinct advantages. Through an outstanding balance of low viscosity and volatility, the new LVLV PAO base stocks help deliver step-out performance, including fuel economy improvements for lower emissions, energy efficiency for extended electric vehicle range and enhanced thermal management for e-motor and electronics. LVLV PAO base stocks also offer superior oxidative stability, which can help with improving the life of the automotive lubricant.
Improved LVLV PAO base stocks with excellent balance of low viscosity-low volatility, superior oxidative stability, improved energy efficiency and thermal management will certainly help formulators continue to deliver innovative lubricants and fluids for the ever-changing automotive market today and tomorrow.
