Ubushushu begumbi vulcanized irabha ye-silicone, efinyeziweyo njenge-RTV.Isiseko sayo sepolima silulwelo olusezantsi{{0}zemolekyuli{1}}lulwelo oluphantsi lwe-hydroxyl{2}}okupheliswa okanye i-vinyl{3}i-polysiloxane ephelisiwe. Ihlala ikwimo yolwelo oluqukuqelayo, intlama okanye iputty phambi kokusetyenziswa.
Eyona nto ibalaseleyo kukuba inokunyangwa kwi-elastomer kwiqondo lobushushu begumbi okanye kufutshane nobushushu begumbi (ngokuqhelekileyo phakathi kwe-0 kunye ne-40 idigri) ngaphandle kokufudumeza okanye ngexabiso elincinci lokufudumala.
Ngokwefomu yokupakisha, ihlelwa njenge: enye-yecandelo lobushushu begumbi elitshisa irabha yesilicone: ishunqulelwe njenge-RTV{3}}1. Onke amacandelo (i-rubber eluhlaza, i-agent agent, i-catalyst, i-filler, njl.) ixutywe kwangaphambili kwaye ifakwe kwisitya esinye.
Ukunyanga kufuna ukufuma emoyeni. Emibini-yecandelo lobushushu begumbi elitshisa irabha yesilicone: ishunqulelwe njenge RTV-2.
Ngokuqhelekileyo ihlulwe ibe ngamacandelo amabini, A kunye no-B (umzekelo, A: irabha eluhlaza + i-filler; B: I-agent ye-Crosslinking + i-catalyst. Xa isetyenziswa, yixube ngokulinganayo kwaye inokunyanga kwiqondo lokushisa ngaphandle kokuthembela kumswakama womoya.
