Rabara ea silicone ea metsi esale e le 'marakeng ka lilemo tse fetang 40,' me tlhahiso ea eona e ntse e eketseha ka sekhahla sa hoo e ka bang 10% ka selemo. Ka lebaka la melemo e mengata e joalo ka lebelo le potlakileng la vulcanization, boemo bo phahameng ba tlhahiso ea othomathike le litšila{3}}tlhahiso ea mahala,e na le mokhoa oa ho nka sebaka-viscosity e phahameng-mocheso oa lirabara tsa silicone tse hlenneng le mocheso oa kamore e nang le rabara e hlephileng ea silicone mafapheng a mangata.
Lilemong tse 20 tse fetileng, mekhoa ea mantlha ea boqapi ba rabara ea silicone ea mokelikeli e bile ho potlakisa lebelo la eona la vulcanization le ho eketsa lihlahisoa tse fapaneng. Mefuta e mecha e kenyelletsa rabara ea silicone e metsi e nang le matla a ho taboha haholo, ha e na poso-kalafo, e hanyetsa mocheso, e thibela ho pholisa, ho itšehla -lubrication, oil resistance, self-adhesion, conductivity (anti{5}}static) le flame retadancy.
