Kunomehluko omkhulu ekusebenzeni kanye nentengo phakathi kwemikhiqizo ye-silica ehlukahlukene engenisiwe kanye neyasekhaya. Mayelana nokusebenza, kunomehluko omkhulu endaweni ethile, usayizi wezinhlayiyana, okuqukethwe ukungcola kanye nomswakama. Ngakho-ke, ngemva kokwenziwa kwe-compound, umbala wokubukeka, ubumhlophe, amaphuzu angcolile, ukucaca kweshidi lenjoloba, izakhiwo zomzimba nezomshini, ukuphuzi ngesikhathi se-vulcanization yesibili kanye nesivinini sokuxuba se-compound konke kuhluke kakhulu. Ngesikhathi esifanayo, amanani ezinhlobonhlobo ezahlukene nawo ahluka izikhathi eziningana. Ngakho-ke, indlela yokukhetha uhlobo lwe-silica yingxenye ebalulekile yokuklama ifomula ehlanganisiwe.
Indlela yokuqinisa i-silica enjolweni ye-silicone ayikaze iqondwe ngokugcwele, esinye sezizathu ezibalulekile kungase kube ukuthi izakhiwo zamakhemikhali zamaketanga amakhulu e-silica nama-molecule enjoloba ye-silicone ziyefana, okuholela ekuxhumaneni okunamandla phakathi kwazo. Ngenxa yokuthi iketango le-oxygen ye-polysilicon kulula ukulikhanga ebusweni bezinhlayiya ze-silica futhi lenze ezinye izixhumanisi zamaketanga zihlelwe ngokuhlelekile, lokhu akwenzi nje kuphela i-silica ibe yindawo ephambanisayo ngokomzimba, kodwa futhi ingaveza umphumela we-crystallization. Ubukhulu bezinhlayiyana ze-silica buba nkulu, indawo yayo engaphezulu iyaba nkulu, futhi kuba ngcono umthelela wayo wokuqinisa kurabha ye-silicone.
Ngaphezu kwalokho, amanye ama-semi-okugcwalisa i-reinforcing nesisindo{1}}ayanda izihlungi, njenge-diatomite, i-calcium carbonate quartz powder, i-titanium dioxide, i-aluminium hydroxide, i-magnesium oxide, njll., kuvame ukungezwa kurabha ye-silicone ukuze kuthuthukiswe ubulukhuni berabha eshisiwe.
