Siloxane And Its Application In Industry

By: Chad DeBolt

Siloxane is a compound that belongs to the Organosilicon group of compounds and has a variety of applications. Typically its units are composed in the form of R2Sio; in this case R is the hydrogen atom, or hydrocarbon group. These have a backbone structure of alternating oxygen and silicon atoms which may or may not be branched. The side chains R attach to the silicon atoms. There are more complex structures available such as a cube with the silicon atoms at the corners and oxygen atoms at the edges.

There are many forms of this compound with different names and classifications. Cyclic Siloxanes include hexamethylcyclotrisiloxane, octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, and dodecamethylcyclohexasiloxane. Linear Siloxanes include: hexamethyldisiloxane, octamethyltrisiloxane, decamethyltetrasiloxane, and polydimethylsiloxane. Each one of these has different applications and uses.

Siloxanes can be found in a variety of household products ranging from deodorants, to soaps. They are also used in windshield coatings, and in some instances cosmetic products. They occur in landfill gas and are currently being evaluated as a replacement for perchloroethylene, which is a compound used in dry cleaning. This compound is considered environmentally unfriendly by most companies, and groups.

Siloxanes also make an appearance in bio gas and can be harmful to engines. Let's take the internal combustion engine that most cars use for example. As the engine is used, deposits of the compound form on the cylinder heads, and pistons. This makes the normally smooth surfaces required for engine operation rough, and jagged. This can lead to engine damage and most require an overhaul around 5000 hours of operation. Turbochargers are also damaged by the compound and will eventually lose efficiency and need to be replaced.

Sterling engines are more resistant to the compound but it does still build up on the tubes leading to the heat exchange unit and will cause a drop in efficiency. This engine does not work on the same principles as the internal combustion engine and as such is more resistant to corrosion. Siloxane has many household uses beyond what was mentioned earlier that many are unaware of. When used properly this compound is safe, and not harmful to humans.

To ensure the safety of the compound, and to launch medical research into it, the Siloxane Research Program or SRP was launched in 1994. It was the largest voluntary research program initiated on the compound and other silicon based compounds. The SRP continues to function and has the support of the six largest silicone manufacturers around the world. They're goal is to research the different types of silicon, and silicon based compounds and determine the effects on human health, if any.

The SRP's approach, research methods, and findings are evaluated by an external board of nationally, and internationally renowned scientists that provide independent reviews and comparisons of the work done. Qualified independent universities and laboratories conduct the actual tests and studies and review them before reporting their progress. Any results gleaned from this research are published in peer reviewed journals across the globe.

Over 100 research reports have been filed to date and they continue to support the safe use of silicon based products alongside humans. As with all compounds and products when handled properly there is no health risk. Silicone manufactures alone have done more than 1000 studies to judge the safety of their products. After all we use silicone in almost everything. You're using it right now if you are viewing this article on a desktop or laptop pc.

Silicon is one of the main ingredients in electronics and is also used in electrical engineering. Another household product featuring silicone and related compounds is calking, solvents, and adhesives. This is the literal glue that holds together houses and buildings across the planet. Siloxane isn't a single compound so much as it is a group of compounds. It can be easy to understand its uses but not so easy to understand its composition. When combined with other natural compounds it produces the products that we use and rely upon for every day life.

In closing Siloxane and all of its different combinations and forms as a compound are very useful, if not essential to our daily lives. As stated above when used properly and safely like any other compound it is perfectly harmless. It has many applications ranging from in home use, to industrial use. Please keep in mind it is just a small part of the silicon family and it has great potential.
