Mocheso o hodimo- rabara ya silicone e hlephileng, e khutsufatswang e le HTV, hape e tsejwa e le mocheso- rabara e silafang e senyehileng kapa rabara e tiileng ya silicone. Polima ea eona ea motheo e hodimo-molecular{4}}boima ba polysiloxane (hangata polydimethylsiloxane), ka boima ba molek'hule ho tloha ho 400,000 ho isa ho 800,000.
Boemong ba eona ba rabara e tala, hangata e hlaha e le semi-e bonaletsang kapa e le lebese le tiileng le bosoeu (joalo ka motsoako oa rabara, lesela la rabara e tala, boloko ba rabara, joalo-joalo) 'me e na le polasetiki e phahameng.
Vulcanization (pheko) e tlameha ho etsoa ka mocheso o batlang o le holimo (hangata pakeng tsa likhato tse 110 le 180, kapa ho feta), e hlokang ts'ebetso ea khatello le nako e itseng ea vulcanization (ho tloha metsotso e seng mekae ho ea ho metsotso e mashome). Ts'ebetso ena hangata e etsoa ka lisebelisoa tse kang ho bopa, extrusion le calendering.
