Irabha yemvelo, njengoba sivame ukubhekisela kuyo, iyinto eqinile eyenziwe nge-latex yemvelo eqoqwe ezihlahleni zenjoloba, ngemva kokuhlangana, ukomisa nezinye izinqubo zokucubungula.Irabha yemvelo iyinhlanganisela ye-polymer yemvelo ene-polyisoprene njengengxenye yayo eyinhloko, ene-molecular formula (C5H8)n.Okuqukethwe kwayo kwerabha i-hydrocarbon (i-polyisoprene) ingaphezu kuka-90%, futhi iqukethe amanani amancane amaprotheni, ama-fatty acids, ushukela kanye nomlotha.
Izinto ezibonakalayo zenjoloba yemvelo.Irabha yemvelo inokunwebeka okuphezulu ekamelweni lokushisa, ipulasitiki encane, amandla amahle kakhulu emishini, ukulahlekelwa kwe-hysteresis ephansi, ukukhiqizwa kokushisa okuphansi ngesikhathi sokuguqulwa okuningi, ngakho-ke ukumelana kwayo okuguquguqukayo nakho kuhle kakhulu, futhi ngenxa yokuthi iyirabha engeyona i-polar, inokuhle. izakhiwo zokufaka ugesi kagesi.
Irabha, kanye namapulasitiki nemicu, ingenye yezinto ezintathu zokwenziwa ezinezinga eliphezulu lokunwebeka nokunwebeka.Irabha ibonakala okokuqala nge-modulus encane kakhulu yokunwebeka kanye nezinga eliphezulu lokwelula.Okwesibili, inokumelana okuhle nokungena kwamanzi kanye nokumelana nemidiya ehlukahlukene yamakhemikhali kanye nokufakwa kukagesi.Amanye ama-rubber okwenziwa akhethekile anokumelana okuhle kwamafutha nokushisa, amelana nokuvuvukala kwamafutha anamafutha, amafutha okugcoba, amafutha we-hydraulic, amafutha kaphethiloli namafutha ancibilikayo;ukumelana nokubanda kungaba ngaphansi kuka -60°C kuya ku-80°C kanti ukumelana nokushisa kungaba phezulu ku-+180°C kuya ku-+350°C.Irabha iphinde imelane nazo zonke izinhlobo zokuguquguquka nokugoba, njengoba ukulahleka kwe-hysteresis kukuncane.Isici sesithathu senjoloba ukuthi ingasetshenziswa, ihlanganiswe futhi ihlanganiswe nezinto ezihlukahlukene futhi ngaleyo ndlela iguqulwe ukuze ithole inhlanganisela enhle yezakhiwo.
