Advantages of silicone oil
(1) The viscosity temperature performance is the best among liquid lubricants, with minimal viscosity changes over a wide temperature range. Its pour point is generally less than -50 ℃, and some can reach as high as -70 ℃. When stored at low temperatures for a long time, the appearance and viscosity of its oil remain unchanged. It is a base oil that balances high temperature, low temperature, and a wide temperature range.
(2) Excellent thermal oxidation stability, such as thermal decomposition temperature>300 ℃, low evaporation loss (150 ℃, 30 days, evaporation loss is only 2%), oxidation test (200 ℃, 72 hours), small changes in viscosity and acid value.
(3) Excellent electrical insulation, volume resistance, etc. do not change within the range of room temperature to 130 ℃ (but the oil cannot contain water).
(4) It is a non-toxic and low foaming oil with strong anti foaming properties, which can be used as a defoamer, etc.
(5) Excellent shear stability, with the function of absorbing vibration and preventing vibration propagation, can be used as a damping fluid.
