SILICONE OIL

CAS Number:63148-62-9
MDL number:MFCD00132673

What is Silicone Oil?
Silicone oil may be used by pharmaceutical companies as a primary ingredient in anti-flatulent medicines.
Silicone oil is similar to a traditional hydrocarbon oil except that its molecular chain replaces carbon units with siloxane units. 
This oil is a nonflammable, nontoxic, tasteless, and odorless material. 
Silicone Oil is widely used by several industries including laboratories and medical facilities. 
Food grade versions of this oil are utilized by restaurants and breweries. 
Pharmaceutical companies also incorporate this oil in certain medicines.

Restaurants may use silicone oil to prevent cooking oils from splattering and foaming.
Traditional hydrocarbon oil is composed of a sequence of carbon particles that typically bond with hydrogen. 
Silicone oil replaces the carbon and hydrogen units with siloxane units. 
These units are composed of silicone particles that have bonded together with oxygen. 
Silicone Oil has been frequently used for certain types of hydraulic applications and as an all-purpose lubricant. 
Silicone Oil is routinely employed as an internal lubricant for air and paintball guns.

Breweries may use silicone oil during their distilling, brewing, and fermenting processes.
Silicone oil also has unique properties that make it suitable for a wide variety of additional applications. 
This oil is well known for its thermal stability at extremely hot and cold temperatures. 
Unlike carbon-based oil, Silicone Oil is also a nonflammable liquid. This oil is odorless and tasteless and often used as an additive to other liquid materials. 
Silicone Oil's nontoxic properties allow it to be used for both food and pharmaceutical applications.

Silicone oil may be used as an internal lubricant for paintball guns.
The exceptional thermal stability of silicone oil makes it ideal for laboratory use. 
Silicone Oil is frequently utilized in heating baths during lengthy experiments. 
Silicone Oil's nonflammable properties make it safe near the open flames of laboratory burners. 
Medical facilities make use of this sterile oil to replace vitreous fluid during eye surgeries. 

A silicone 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

Applications of Silicone Oil
Silicone oils are primarily used as lubricants, thermic fluid oils or hydraulic fluids. They are excellent electrical insulators and, unlike their carbon analogues, are non-flammable. 
Silicone Oil temperature stability and good heat-transfer characteristics make them widely used in laboratories for heating baths ("oil baths") placed on top of hotplate stirrers, as well as in freeze-dryers as refrigerants. 
Silicone oil is also commonly used as the working fluid in dashpots, wet-type transformers, diffusion pumps and in oil-filled heaters. 
Aerospace use includes the external coolant loop and radiators of the International Space Station Zvezda module, which rejects heat in the vacuum of space.

The class of silicone oils known as cyclosiloxanes has many of the same properties as other non-cyclic siloxane liquids but also has a relatively high volatility, making it useful in a number of cosmetic products such as antiperspirant.

Some silicone oils, such as simethicone, are potent anti-foaming agents due to their low surface tension. 
Silicone Oil is  used in industrial applications such as distillation or fermentation, where excessive amounts of foam can be problematic. 
Silicone Oil is sometimes added to cooking oils to prevent excessive foaming during deep frying. 
Silicone oils used as lubricants can be inadvertent defoamers (contaminants) in processes where foam is desired, such as in the manufacture of polyurethane foam.

Silicone oil is also one of the two main ingredients in Silly Putty, along with boric acid.

Areas of application of Silicone Oil
Parting agent at foundry operations injection moulding, blowing and extruding processes of plastics and elastomer
Avoids the sticking of e.g. adhesives and sealing excess or water wetting
Sliding agent against noisy rubbing of plastics, elastomers and metals together or against each other
Lubrication of cutting edges in the paper, cardboard, veneer layer and textile processing machines
For easy retracting of plastic and rubber profiles, e.g. in the door and window production

Medical uses of Silicone Oil
Consumer products to control flatulence often contain silicone oil. 
Silicone oils have been used as a vitreous fluid substitute to treat difficult cases of retinal detachment, such as those complicated with proliferative vitreoretinopathy, large retinal tears, and penetrating ocular trauma. 
Additionally, silicone oil is used in general medicine and surgery. 
Because of silicone oil's water repellent and lubricating properties, it is considered an appropriate material to maintain surgical instruments. 
Silicone Oil also used in digital rectal examinations (DRE).

Automotive use of Silicone Oil
Silicone oil has been commonly used as the fluid in the automobile cooling fan clutch assemblies, and is still being used in the newer electronic fan clutches.

Silicone oil molecular structure
The repeating backbone of silicone oils and other siloxane polymers consists of alternating silicon and oxygen atoms.  
Silicone oils are comprised of linear repeating chains of silicon and oxygen, with each silicon atom also having two carbon-based substituents, which are most often methyl groups.  
The silicone oils can possess a degree of polymerization, in other words the average number of repeating siloxane groups in a polymer chain, ranging from several units to several thousand units.  
Replacing a small portion of the methyl groups with phenyl groups or amino functional groups can change how the siloxane polymers interact with other materials.  
Adding reactive organic groups to siloxane polymers can also allow for siloxane polymers to be integrated into various type of organic polymers, which can result in some unique properties when compared to standard organic polymers.

Silicone oil properties
The viscosity of silicone oils can vary greatly 0.65cs to 2,000,000cs and the viscosity remains constant across a wide range of temperatures.  
Silicone Oils also exhibit remarkable thermal stability (up to 250°C) when compared to some organic polymers, due to special characteristics of the chemical bonds between silicon and oxygen in the polymer chain.  
Silicone Oil on surfaces very easily, due to their very low surface tension, and have high compressibility when compared to different hydrocarbon and mineral oils.  
Silicone Oilhave good dielectric properties and remarkable resistance to shear stress, natural ageing, oxidation and hydrolysis.
