Silicone | Definition, Composition, Properties, Uses, & Facts
Oct 18, 2024 · 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 Polymers - Chemistry LibreTexts
Jan 23, 2023 · Silicone polymers, more properly called polysiloxanes, do not have carbon as part of the backbone structure. Although silicon is in the same group as carbon in the periodic table, it has quite different chemistry. Many silanes are known which are analogous to the hydrocarbons with Si-Si bonds.
Silicone Polymer - an overview | ScienceDirect Topics
Silicone polymers are hybrid organic/inorganic polymers that exhibit low surface energy and high flexibility. They possess excellent physical properties such as water repellency, heat stability, and resistance to chemical and UV attack.
Polydimethylsiloxane - Wikipedia
Polydimethylsiloxane (PDMS), also known as dimethylpolysiloxane or dimethicone, is a silicone polymer with a wide variety of uses, from cosmetics to industrial lubrication and passive daytime radiative cooling.
Silicone - an overview | ScienceDirect Topics
Polysiloxanes, more commonly referred to as silicones, are polymers with alternating silicon and oxygen atoms in the molecule backbone and with the possibility of a variety of pendant groups attached to the silicon, resulting in the repeat structure –[SiR2–O–]–.
Silicon-Containing Polymers: The Science and Technology of …
The broad class of model materials known as silicones is based on polysiloxanes. They are also the best known, as most research in the area of silicon polymers has for many years been directed towards the synthesis of new polysiloxanes, to understanding their properties and to extending their applications.
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.
Polysiloxane (Silicone) | Formula, Properties & Application
Polysiloxanes, commonly known as silicones, are synthetic polymers renowned for their high versatility and broad application spectrum. These polymers are made up of silicon and oxygen atoms, which are held together in a durable backbone, complemented by carbon and hydrogen atoms found on the side groups.
