(1) The viscosity temperature performance is the best among liquid lubricants, and the viscosity changes little in a wide temperature range. Its freezing point is generally less than - 50 ℃, some as high as - 70 ℃, long-term storage at low temperature, the appearance of the oil, viscosity unchanged, it is a high temperature, low temperature, wide temperature range of both base oil.
(2) Excellent thermal oxidation stability, such as thermal decomposition temperature > 300 ℃, evaporation loss is small (150 ℃, 30 days, evaporation loss is only 2%), oxidation test (200 ℃, 72h), viscosity and acid value change is small.
(3) Excellent electrical insulation, volume resistance, etc. do not change in the range of room temperature to 130 ℃ (but the oil can not contain water).
(4) It is a non-toxic oil with low foaming property and strong anti foaming property. It can be used as defoamer.
(5) Excellent shear stability, with the function of absorbing vibration and preventing vibration propagation, it can be used as damping fluid.
