Amandla aphathekayo erabha ye-silicone ezingeni lokushisa legumbi angaphansi kancane kunawamanye amarabha ezinto eziphilayo, kodwa ngaphansi-izimo zezinga lokushisa eliphezulu, amandla ayo avelele kakhulu.
Isibonelo, isethi yokucindezelwa kwerabha ye-silicone ngemva kokucindezelwa ku-150℃amahora angu-70 ingu-7% kuya ku-10%. Le sethi yokuminyanisa ephansi iyenza ibe into enhle kakhulu yokuvala izingxenye ezifana ne-O-amaringi, ama-gaskets namawasha asetshenziswa emazingeni okushisa aphezulu. Ngaphezu kwalokho, irabha ekhethekile ye-silicone nayo ingaba nokumelana nemisebe.
Isibonelo, irabha ye-phenyl silicone inamandla okumelana-nezinga eliphezulu emisebeni yezinga lokushisa futhi isengagcina ukunwebeka ngisho nalapho i-Y-ray iphezulu njengo-1X109R.
