Silicone - Wikipedia
WEBIn organosilicon and polymer chemistry, a silicone or polysiloxane is a polymer composed of repeating units of siloxane (−O−R 2 Si−O−SiR 2 −, where R = organic group). They are typically colorless oils or rubber-like substances. Silicones are used in sealants, adhesives, lubricants, medicine, cooking utensils, thermal insulation, and ...
Polysiloxane - an overview | ScienceDirect Topics
WEBPolysiloxanes are chains, rings, ladders, and 3D network polymers that contain siloxane (Si O Si) bonds in the backbone. The basic structural units of polysiloxanes are. Chain polysiloxanes are composed of difunctional units. The framing groups (R) are either H or organic moieties and the end groups are usually OR or a monofunctional siloxyl unit.
Polysiloxane (Silicone) | Formula, Properties & Application
WEBPolysiloxanes, 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.
Siloxane - Wikipedia
WEBPolydimethylsiloxane is a prevalent siloxane. In organosilicon chemistry, a siloxane is an organic compound containing a functional group of two silicon atoms bound to an oxygen atom: Si−O−Si. The parent siloxanes include the oligomeric and polymeric hydrides with the formulae H [OSiH2]nOH and [OSiH2]n. [1]
Polysiloxane - an overview | ScienceDirect Topics
WEBPolysiloxanes (silicones) Polysiloxanes are widely used for medical applications and have a long success record. Material types include elastomers, gels, lubricants, foams and adhesives. Polysiloxanes are very chemically stable and unreactive. They are very hydrophobic and have a low moisture uptake.
Silicone | Definition, Composition, Properties, Uses, & Facts
WEBSilicone, 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
WEBJan 23, 2023 · 1132. 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.
