I- silicone noma i- polysiloxane iyi- polymer eyenziwe nge- siloxane (2R 2 Si − O − SiR 2 -, lapho R = iqembu lezinto eziphilayo).Ngokuvamile akunambala, uwoyela noma izinto ezifana nenjoloba.Ama-silicone asetshenziswa kuma-sealants, ama-adhesives, izinto zokuthambisa, imithi, izitsha zokupheka, nokufakwa okushisayo nokugesi.Amanye amafomu ajwayelekile afaka uwoyela we-silicone, i- silicone grease, iraba le- silicone, i-resin ye-silicone, ne-silicone caulk. Okuningi ngokunembile ngokuthi polymerized siloxanes noma polysiloxanes, silicones aqukethe i wezinto Silicon--mpilo backbone uchungechunge (⋯ -Si-O-Si-O-Si-O- ⋯) nemacembu lamabili organic enamathiselwe ngamunye isikhungo silicon.Imvamisa, amaqembu aphilayo yi-methyl.Izinto zokwakha zingaba yi-cyclic noma i-polymeric.Ngokushintshashintsha ubude beketanga le-iSi − O−, amaqembu asemaceleni, nokuxhumeka kwe-crosslinking, ama-silicone angahlanganiswa nezinto eziningi ezahlukahlukene nokwakhiwa.Zingahluka ngokungaguquguquki kusuka kuketshezi kuya ku-gel kuye kuraba kuye kupulasitiki onzima.I-siloxane ejwayelekile kakhulu i-linear polydimethylsiloxane (PDMS), uwoyela we-silicone.Iqembu lesibili ngobukhulu lezinto zokwenziwa ze-silicone lincike ezinhlakeni ze-silicone, ezakhiwa ngama-oligosiloxanes anamagatsha kanye nezinyosi.
