Ama-molecule e-silicone yerabha ye-polymer ayiketango-njengezakhiwo ezakhiwe ngamabhondi e-Si-O (silicon{2}}oxygen), futhi ingxenye yawo eyinhloko i-molar mass linear polysiloxane ephezulu. Ngenxa yokuthi i-Si-O-I-Si bond iwuhlobo lwayo oluyisisekelo lwebhondi, ama-athomu e-silicon axhunywe ikakhulukazi kumaqembu e-methyl, futhi inani elincane kakhulu lamaqembu angagcwalisiwe ethulwa emaketangeni aseceleni.
Amandla e-intermolecular mancane, futhi ama-molecule anesakhiwo se-helical. Amaqembu e-Methyl ahlelwe ngaphandle futhi angakwazi ukujikeleza ngokukhululekile, okwenza irabha ye-silicone ibe nokumelana nokushisa okungcono, ukufakwa kukagesi, ukuzinza kwamakhemikhali, njll kunamanye ama-rubber avamile.
Irabha ye-silicone evamile, okuyi-polydiformaldehyde siloxane, inokucushwa kwe-helical yamangqamuzana anamandla ama-intermolecular amancane uma kuqhathaniswa, ngaleyo ndlela ikwazi ukumelana nokuqina. Ngaleso sikhathi, amaqembu e-formaldehyde akhomba ngaphandle kwe-helix angakwazi ukuzungeza ngokukhululeka, okwenza irabha ye-silicone ibe nezinto ezihlukile ezingaphezulu njenge-hydrophobicity kanye{1}}nokunganamatheli kobuso.
