Properties: Dimethicone silicone oil is a transparent, colorless, tasteless, odorless, non-toxic oily liquid. It has high flash point, low freezing point, good thermal stability, high and low temperature resistance and other characteristics. It can be used for a long time under -50 ℃ - +180 ℃, such as in the air insulation or inert gas in the long-term use of the temperature up to 200 ℃. The surface tension of silicon is very small, the compression rate, good anti-shear performance, viscosity temperature coefficient is small, the dielectric loss is small; electrical insulation resistance, corona, non-flammable; water-repellent and moisture-proof, but also has good physiological inertia.
