Silicone - Wikipedia
网页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
网页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.
Silicon - Wikipedia
网页Silicon is a chemical element; it has symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic luster, and is a tetravalent metalloid and semiconductor. It is a member of group 14 in the periodic table: carbon is above it; and germanium, tin, lead, and flerovium are below it. It is relatively unreactive.
Silicone rubber - Wikipedia
网页Silicone rubber is an elastomer (rubber-like material) composed of silicone—itself a polymer—containing silicon together with carbon, hydrogen, and oxygen. Silicone rubbers are widely used in industry, and there are multiple formulations.
Silicone: Definitions, History, and Uses - ThoughtCo
网页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.
What Are Silicones? - Global Silicones Council
网页Silicones display a host of unique properties that can lubricate, seal, bond, release, defoam, spread, and encapsulate. They can even insulate, waterproof, and coat. They do not conduct electricity and will not harden, crack, peel, …
What Is the Difference Between Silicon and Silicone?
