| Santolube HiVis Base Oil粘度620的基礎油。They are available currently in two viscosity grades for blending from ISO 22 to ISO 680 products. These new base oils have extreme high Viscosity Indices (VI) and extremely low elastohydrodynamic shear strengths (or coefficients of traction) over a wide range of conditions. In fact, they have the lowest coefficients of traction ever reported. These two major features make these base oils suitable for blending lubricating fluids with excellent film thickness protection across a wide temperature range and for blending lubricating fluids with unprecedented energy efficiency. Additionally, they are completely stable to viscosity sheardown in EHL applications and thus maintain their superior lubricating throughout their long service life in properly formulated fluids |
