What Is Silicone Oil/Fluid?

A silicone oil(Silicone Fluid,Silikon Oil) is any liquid polymerized siloxane with organic side chains. The most important member is polydimethylsiloxane. These polymers are of commercial interest because of their relatively high thermal stability and their lubricating properties.

Silicone Oil/Fluid Properties

Siloxane bonds have very strong bonding energy and are not easily broken. Therefore, silicone oil has an excellent heat resistance and weather resistance and is also chemically extremely stable. Another characteristic is that the amount of change in viscosity due to temperature change is also small. Because of this property, silicone oil is also used in instrument oil and other oils that utilize the viscosity of oil, such as in automobiles and railroad vehicles.Another feature of silicone oil is that its surface tension is much smaller than that of water or general synthetic oils, allowing silicone oil to spread on the surface of various substances without being repelled. Silicon oil has many other unique properties and is used in a wide variety of applications. Click to learn more.

What Is Silicone Oil/Fluid Used for?

Silicon oil is used in manufacturing and industrial applications. This includes electrical insulating oil, lubricating oil, and anti-vibration oil, as well as cosmetics, anti-foaming agents, and water-repellent treatments for textiles and glass. Silicone fluid in the textile and apparel industry can be used as fabric softening agent, lubricant, waterproofing agent, finishing agent, etc..

Advantages of Silicone Fluid

(1) The viscosity and temperature performance is the best among liquid lubricants, and the viscosity changes little in wide temperature range. Its freezing point is generally less than -50℃, some are as high as -70℃, and its oil appearance and viscosity do not change when stored for a long time at low temperature, it is a base oil that can take into account high temperature, low temperature and wide temperature range.

(2) Excellent thermal oxidation stability, such as thermal decomposition temperature >300℃, small evaporation loss (150℃, 30 days, evaporation loss is only 2%), oxidation test (200℃, 72h), small changes in viscosity and acid value.

(3) excellent electrical insulation, volume resistance, etc. does not change in the range of room temperature ~ 130 ℃ (but the oil can not contain water).

(4) It is a non-toxic and low foaming, strong anti-foaming oil, can be used as antifoaming agent, etc.

(5) Excellent shear stability, has the function of absorbing vibration and preventing vibration transmission, and can be used as vibration damping fluid.

Safety of Silicon Oil

Silicon oil is a physiologically inert substance. It has almost no skin irritation, eye irritation, or acute toxicity and is harmless unless ingested in large quantities. However, when heated to a temperature of 150°C or higher in an air atmosphere, a small amount of harmful formaldehyde may be produced.
