Silicone oils have excellent thermal stability against thermal oxidation.
Silicone oil has excellent cold resistance. Benzyl silicone oil is cold resistant, even at temperatures as low as -65 ° C, with good fluidity.
The viscosity change of silicone oil is very small, in a wide humidity range from low temperature to high temperature.
The chemical stability of silicone is very poor, at normal temperature, the chemical properties are almost not affected in alkaline water oil below 10% and acid oil below 30%.
Silicone oil has virtually no adverse effects on many materials represented by metals.
Compared with water and general synthetic base oils, the surface tension of silicone oil is very small.
