Ngokuvumelana nomehluko wezindlela nezimo ze-vulcanization, irabha ye-silicone ngokuvamile ihlukaniswa yaba izinhlobo ezimbili: irabha ephezulu-yezinga lokushisa elishisayo kanye{1}}nezinga lokushisa lerabha elivuthisiwe.
Ngokwefomu lomkhiqizo nendlela yokuhlanganisa,-izinga eliphezulu lokushisa i-siliconerubber ihlukaniswa ibe yi-high consistencyrubber (HCR) kanye ne-liquid siliconerubber (R). Ithempelesha ephezulu-yerabha eluhlaza ye-silicone ene-vulcanized yi-polyorganosiloxane enesisindo esiphezulu-i-molecular{4}} (enesisindo se-molecular ngokuvamile sisuka ku-400,000 kuya ku-800,000). Isisindo se-molecular yegumbi{10}}lokushisa kwenjoloba eluhlaza ye-silicone evamise ukuba ngaphansi (kusuka ku-30,000 kuye ku-60,000), ngeqembu elilodwa noma amabili asebenzayo ekugcineni ngakunye kweketango le-molecular (ngezinye izikhathi liphakathi nendawo). Ngaphansi kwezimo ezithile (umswakama osemoyeni, ama-ejenti axhumanisayo afanelekile nama-catalyst), Lawa maqembu asebenzayo angasabela, ngaleyo ndlela akhe uhlaka oluxhunywe{16}}nobukhulu obuthathu{17}}.
Irabha yegumbi-yezinga lokushisa lerabha ye-silicone evuvukele ingahlukaniswa ngohlobo lokujiya kanye nohlobo lokwengeza ngokuya ngendlela yayo yokwenza i-vulcanization. Ngokwezindlela zabo zokupakisha, zingaphinda zihlukaniswe zibe izingxenye ezimbili-nezinhlobo-zengxenye eyodwa. Izakhiwo ezijwayelekile-zerabha ye-silicone evuvukele ephezulu negumbi{6}}lezinga lokushisa elishisayo irabha ye-silicone iboniswa ngokulandelana kuThebula 6.1 no-6.2. -I-viscosity ephezulu{10}}yezinga lokushisa eliphakeme lerabha yerabha ye-silicone ithatha cishe u-80% wesabelo semakethe yenjoloba ye-silicone yomhlaba wonke, kuyilapho irabha ye-silicone eyi-liquid negumbi{12}}izinga lokushisa elivalekile irabha ye-silicone i-akhawunti ngayinye cishe ngo-10%. Irabha ye-silicone ephulukiswe ukuchayeka ekukhanyeni iwuhlobo olusha lomkhiqizo werabha we-silicone, futhi isabelo sayo semakethe sisasesincane uma kuqhathaniswa okwamanje.
