Rabara ea Styrene-Butadiene
Selelekela sa lintho tse bonahalang:
Rabara ea styrene-butadiene (SBR), eo hape e tsejoang e le rabara ea polybutadiene, ke rabara ea maiketsetso. E entsoe ka polymerization ea li-monomers tse peli, butadiene le styrene. SBR e na le khanyetso e ntle ea ho roala, ho hanyetsa botsofali le elasticity, 'me e sebelisoa haholo liketsahalong tse fapaneng.
Sebaka sa ts'ebeliso:
Ho etsa lithaere: SBR ke e 'ngoe ea liraba tse sebelisoang haholo ho etsa lithaere. E ka sebelisoa holim'a lithaere tsa mabili, maboteng a mahlakoreng le 'meleng ho fana ka ts'ebetso e ntle le ho hanyetsa ho apara.
Lihlahisoa tsa rabara : SBR e sebelisetsoa ho hlahisa lihlahisoa tse sa tšoaneng tsa rabara, tse kang litiiso, liphaephe, liphaephe, MATS tsa rabara, joalo-joalo.
Sole: Hobane SBR e na le khanyetso e ntle ea ho roala le ho thibela ho thella, hangata e sebelisoa ha ho etsoa lieta tsa lipapali, lieta tsa mosebetsi le li-soles tse ling.
Likhomaretsi tsa indasteri: SBR e sebelisoa hangata e le karolo ea likhomaretsi tsa indasteri ho kopanya lisebelisoa tse fapaneng tse kang tšepe, polasetiki le lehong.
Lisebelisoa tsa lipapali: SBR e boetse e sebelisoa ho etsa lisebelisoa tsa lipapali tse kang basketball le bolo ea maoto, hammoho le libaka tsa ho matha le lisebelisoa tsa boikoetliso.

Mekhoa ea ho Etsa Lihlahisoa tsa Rabara
Tlhahiso ea thepa ea rabara e kenyelletsa mekhoa e mengata e rarahaneng e fetolang thepa ea rabara hore e be lihlahisoa tsa ho qetela. Mekhoa ena e fapana ho latela mofuta oa rabara e sebelisoang le ntho e itseng e etsoang. Tse latelang ke lits'ebeletso tsa tlhahiso ea rabara tseo re fanang ka tsona ho tšehetsa litlhoko tsa hau:

Ho etsa ente ho kenyelletsa ho kenya rabara e qhibilihisitsoeng ka har'a hlobo e tlas'a khatello e matla. Ts'ebetso ena e nepahetse bakeng sa ho etsa likarolo tse rarahaneng le tse nepahetseng, ho kenyeletsoa likarolo tsa koloi le thepa ea bareki. Overmolding le ho kenya ho bōptjoa ke mefuta e fapaneng ea ts'ebetso ena, e kenyelletsang ho kopanngoa ha likarolo tsa tšepe tse phethiloeng ka har'a mokoti oa hlobo pele o kenya rabara.

Ho fetisoa Moulding
Ho kopanya likarolo tsa ho hatella le ho etsa ente, ho bopa ho fetisa ho sebelisa tekanyo e lekantsoeng ea rabara ka kamoreng e futhumetseng. Plunger e qobella thepa hore e be mokoti oa hlobo, e etsa hore e tšoanelehe bakeng sa ho hlahisa likhokahanyo tsa motlakase, li-grommets le likarolo tse nyane tse nepahetseng.

Extrusion
Extrusion e sebelisoa ho theha bolelele bo tsoelang pele ba rabara e nang le libopeho tse fapaneng tse fapaneng, joalo ka li-hoses, li-tubing le li-profiles. Rabara e qobelloa ka lefu ho finyella tlhophiso e lakatsehang.

Ho phekola (Vulcanization)
Ho phekola, kapa vulcanization, ho kenyelletsa ho hokahanya liketane tsa polymer ea rabara ho matlafatsa matla, elasticity le ho hanyetsa mocheso.
