What are silicones made of?
More precisely called polymerized siloxanes or polysiloxanes, silicones consist of an inorganic silicon–oxygen backbone chain (⋯−Si−O−Si−O−Si−O−⋯) with two organic groups attached to each silicon center. Commonly, the organic groups are methyl. The materials can be cyclic or polymeric. By varying the −Si−O− chain lengths, side groups, and crosslinking, silicones can be synthesized with a wide variety of properties and compositions. They can vary in consistency from liquid to gel to rubber to hard plastic. The most common siloxane is linear polydimethylsiloxane (PDMS), a silicone oil. The second-largest group of silicone materials is based on silicone resins, which are formed by branched and cage-like oligosiloxanes.
What are the properties of silicon?
Silicones exhibit many useful characteristics, including: 1 Low thermal conductivity 2 Low chemical reactivity 3 Low toxicity 4 Thermal stability (constancy of properties over a wide temperature range of −100 to 250 °C) 5 The ability to repel water and form watertight seals. 6 Does not stick to many substrates, but adheres very well to others, e.g. glass 7 Does not support microbiological growth 8 Resistance to oxygen, ozone, and ultraviolet (UV) light. This property has led to the widespread use of silicones in the construction industry (e.g. coatings, fire protection, glazing seals) and the automotive industry (external gaskets, external trim). 9 Electrical insulation properties. Because silicone can be formulated to be electrically insulative or conductive, it is suitable for a wide range of electrical applications. 10 High gas permeability: at room temperature (25 °C), the permeability of silicone rubber for such gases as oxygen is approximately 400 times that of butyl rubber, making silicone useful for medical applications in which increased aeration is desired. Conversely, silicone rubbers cannot be used where gas-tight seals are necessary such as seals for high-pressure gasses or high vacuum.
What is the chemical structure of silicone?
Chemical structure of the silicone polydimethylsiloxane (PDMS) More precisely called polymerized siloxanes or polysiloxanes, silicones consist of an inorganic silicon–oxygen backbone chain (⋯−Si−O−Si−O−Si−O−⋯) with two organic groups attached to each silicon center. Commonly, the organic groups are methyl. The materials can be cyclic or polymeric.
What is the difference between silicone and benzophenone?
Kipping coined the word silicone in 1901 to describe the formula of polydiphenylsiloxane, Ph 2 SiO (Ph denoting phenyl, C 6 H 5 ), by analogy with the formula of the ketone benzophenone, Ph 2 CO (his term was originally silicoketone ). Kipping was well aware that polydiphenylsiloxane is polymeric whereas benzophenone is monomeric and noted the contrasting properties of Ph 2 SiO and Ph 2 CO. The discovery of the structural differences between Kipping's molecules and the ketones means that silicone is no longer the correct term (though it remains in common usage) and that the term siloxane is preferred according to the nomenclature of modern chemistry.
Why are electronics encased in silicone?
Electronic components are sometimes encased in silicone to increase stability against mechanical and electrical shock, radiation and vibration, a process called "potting". Silicones are used where durability and high performance are demanded of components under hard conditions, such as in space (satellite technology).
What is silicone caulk used for?
Silicone caulk can be used as a basic sealant against water and air penetration.
Why is silicon used in aerospace?
Silicone is a widely used material in the aerospace industry due to its sealing properties, stability across an extreme temperature range, durability, sound dampening and anti-vibration qualities, and naturally flame retardant properties. Maintaining extreme functionality is paramount for passenger safety in the aerospace industry, so each component on an aircraft requires high-performance materials.
