Silicones are used for low-temperature lubrication, including in vacuum pumps and high-temperature oil baths, because their viscosity stays essentially constant with temperature (unlike an ordinary oil, they do not thicken in winter cold).
Step 2. They are used to make waterproof clothing, exploiting their strongly water-repellent surface character (the organic side groups around each silicon make the molecule resemble a hydrocarbon).
Step 3. They are used as insulating material in electric motors and other electrical appliances, drawing on their good thermal AND electrical insulating properties together. …
