Silicone - Wikipedia
Silicon is a chemical element, a hard dark-grey semiconducting metalloid, which in its crystalline form is used to make integrated circuits ("electronic chips") and solar cells.
Silicone | Definition, Composition, Properties, Uses, & Facts
6 天之前 · Silicone, any of a diverse class of fluids, resins, or elastomers based on polymerized siloxanes, substances whose molecules consist of chains made of alternating silicon and oxygen atoms. Silicones have a wide range of commercial applications, from lubricating greases to biomedical implants.
Silicone: Definitions, History, and Uses - ThoughtCo
2019年1月11日 · Silicones are a type of synthetic polymer, a material made of smaller, repeating chemical units called monomers that are bonded together in long chains. Silicone consists of a silicon-oxygen backbone, with “sidechains” consisting of hydrogen and/or hydrocarbon groups attached to the silicon atoms.
Silicone Material - an overview | ScienceDirect Topics
Silicones are a polymer type characterized by a silicon–oxygen bond that can provide glass-like properties, making silicones typically more inert, thermally and optically stable, and optically clear, than most organic polymers.
Silicone - an overview | ScienceDirect Topics
Silicones are a class of synthetic compounds, the molecules of which consist of polymer chains of alternately connected silicon and oxygen atoms. They are found in a variety of applications with requirements ranging from long life at elevated temperatures to fluidity at low temperatures.
What Is the Difference Between Silicon and Silicone?
2018年4月4日 · Silicon is naturally occurring element, while silicone is a synthetic polymer made of carbon, silicon, oxygen, hydrogen, and other elements. Silicon is element 14 on the periodic table. This semimetal makes up 25.7% of the Earth’s crust and is a key element in sand. The element does not occur free in nature, but is part of many compounds.
What Are Silicones? - Global Silicones Council
“Silicone” is a generic term referring to a class of synthetic polymers that are based on a framework of alternating silicon and oxygen (siloxane) bonds with at least one organic group attached to the silicon atom via a direct carbon-silicon bond.
Silicones - Essential Chemical Industry
Silicones are synthetic polymers with a silicon-oxygen backbone similar to that in silicon dioxide (silica), but with organic groups attached to the silicon atoms by C-Si bonds. The silicone chain exposes organic groups to the outside. Thus, despite having a very polar chain, the physical properties of silicones are similar to those of an alkane.

2000年7月1日 · The two approaches are (i) to make emultions that contain silicone oil and a surfactant pair and the (ii) to make modify the molecule chemically to make the product more water-compatible.
Silicone compounds are unique materials both in terms of the chemistry and in their wide range of useful applications. Silicon in combination with organic compounds provides unique properties that function over a wide temperature, making the silicone based products less temperature sensitive than most organic surfactants.
