Silicones | Uses, Benefits, and Chemical Safety FactsSilicones , also known as polysiloxanes , are polymers that include any synthetic compound made up of repeating units of siloxane , which is a chain of alternating silicon atoms and oxygen atoms, combined with carbon , hydrogen , and sometimes other elements. They are typically heat-resistant and either liquid or rubber -like, and are used in sealants, adhesives, lubricants, medicine, cooking utensils, and thermal and electrical insulation. Some common forms include silicone oil , silicone grease , silicone rubber , silicone resin , and silicone caulk. These silicon atoms are tetravalent. So, silicones are polymers constructed from inorganic -organic monomers. Silicones have in general the chemical formula [R 2 SiO] n , where R is an organic group such as an alkyl methyl , ethyl or phenyl group.

Tiwari, with no by-products. The chemical structure is related to the characteristic features of the siloxanes and polysiloxanes, which determine the beneficial and unique properties. Branches or crosslinks in the polymer chain can be introduced by using organosilicone precursors with fewer alkyl groups, A.
