Dimethicone is a transparent, colorless, tasteless, odorless and non-toxic oily liquid. According to the supply of dimethyl silicone oil, it has the characteristics of high flash point, low freezing point, good thermal stability, and high and low temperature resistance. It can be used for a long time at -50℃~+180℃. If it is isolated from air or in an inert gas, the temperature can reach 200℃. The surface silicon tension of the oil is very small, the compressibility is large, the shear resistance is good, the viscosity-temperature coefficient is small, and the dielectric loss is small; it is resistant to arcs, corona, and is not flammable; it is hydrophobic and moisture-proof, and it also has good physiological inertness.
Application of dimethyl silicone oil in mechanical and electrical industry:
Dimethyl silicone oil is widely used in motors, electrical appliances, In electronic instruments, it is used as an insulating medium that is temperature-resistant, arc-corona resistant, corrosion-resistant, moisture-proof, and dust-proof. It is also currently used as an impregnating agent for transformers, capacitors, and TV scanning transformers.
Used as liquid shockproof and damping materials in various precision machinery, instruments and meters.
The shock-absorbing performance of dimethyl silicone oil is less affected by temperature. It is mostly used in instruments with strong mechanical vibrations and large changes in ambient temperature, such as instruments in airplanes and automobiles. It is used for shockproofing, damping, and stabilizing instrument readings. It can also be used as a liquid spring and in the landing device of aircraft.
