Izinto ezisetshenziswayo zokusetshenziswa ezinogwebu zihlanganisa irabha eluhlaza ye-silicone, ama-ejenti akhihlizayo, ama-ejenti aqinisayo nezinye izithasiselo (njengama-flame retardants, ama-colorants, izinto zokuthambisa, izinto ezikhulula isikhunta, njll.).
Impahla eluhlaza yerabha eluhlaza egwebulile iyirabha eqinile ye-silicone, kuyilapho leyo yerabha eluhlaza ebunjiwe iyirabha ewuketshezi ye-silicone. Lesi sakamuva sinokusabela okuphelele kanye namabhamuza afanayo.
Wonke ama-ejenti akhipha ugwebu angama-agent akhipha amagwebu amakhemikhali. Emazingeni okushisa athile, zibola ukuze zikhiqize igesi, okwenza i-silicone yande futhi yenze ama-bubbles, okwenza i-silicone ibe nezici zokuminyana okuphansi, ukuthambile nokulingana.
I-ejenti eyenza i-vulcanizing ibangela ukuthi irabha eluhlaza ibhekane-nokusabela okuxhumanisayo okuphambanayo, okwenza{1}}isakhiwo senethiwekhi esinezinhlangothi ezintathu, esinikeza irabha ye-silicone amandla athile nokunwebeka. Ama-reinforcing agents asetshenziselwa ukuqinisa amandla nokumelana nokugqoka kwe-silicone.
