Iimolekyuli ze-silicone yerabha yepolymer ziyitsheyini-ezifana nezakhiwo ezenziwe yi-Si{1}}O (isilicon{2}}ioksijini) iibhondi, kwaye inxalenye yazo iphezulu ye-molar mass linear polysiloxane. Kuba iSi{4}}O{5}}Si bond luhlobo lwayo olusisiseko lwebhondi, iiathom zesilicon ziqhagamshelwe ikakhulu kumaqela emethyl, kwaye inani elincinci kakhulu lamaqela angaxutywanga aziswa kumatyathanga asecaleni.
Amandla e-intermolecular amancinci, kwaye iimolekyuli zinesakhiwo se-helical. Amaqela e-Methyl ahlelwe ngaphandle kwaye ayakwazi ukujikeleza ngokukhululekileyo, okwenza i-rubber ye-silicone ibe nokumelana nokushisa okungcono, ukutshatyalaliswa kombane, ukuzinza kweekhemikhali, njl. kunezinye iirubha eziqhelekileyo.
Irabha eqhelekileyo ye-silicone, ebizwa ngokuba yi-polydiformaldehyde siloxane, inolungelelwaniso lwemolekyuli ye-helical enamandla amancinane e-intermolecular, ngaloo ndlela inokomelela okugqwesileyo. Okwangoku, amaqela e-formaldehyde akhomba ngaphandle kwe-helix ayakwazi ukujikeleza ngokukhululekileyo, enika irabha ye-silicone kunye neempawu ezikhethekileyo zomhlaba ezifana ne-hydrophobicity kunye ne-surface non{1}}
