It is thermally stable to thermal oxidation.
Benzyl silicone oil is cold resistant even at temperatures as low as -65 °C.
The change in viscosity is very small, over a wide range of humidity from low to high temperatures.
The chemical stability of organosilicon is very poor, almost unaffected in oil, alkali, water below 10% and acid oil below 30%.
Silicone oil has virtually no adverse effects on metal-based materials.
The surface tension of silicone oil is small.
