Iinxalenye zerabha zendalo zifumaneka kakhulu kwi-latex yomthi weHevea brasiliensis, ovela eBrazil kodwa ngoku utyalwa kakhulu kumazwe akuMzantsi-mpuma weAsia afana neMalaysia neIndonesia. Xa ixolo lomthi lisikiwe, i-latex, ulwelo olumhlophe olufana nobisi, iyaphuma. Le latex iqulethe malunga nesinye kwisithathu samanzi kunye nesinye kwisithathu sesithathu seenxalenye zerabha kwi-colloidal suspension. Ezi nxalenye zenziwe ngaphakathi kweeseli ezikhethekileyo ze-latex ezivelisa iiseli ezibizwa ngokuba zii-laticifers. Irabha kwi-latex yi-polymer ye-isoprene, enefomyula yekhemikhali (C₅H₈)ₙ. Emva kokuqokelelwa, i-latex iyaqhubeka nokucutshungulwa ukuze yahlulwe kwaye icoce iinxalenye zerabha.

Amasuntswana erabha enziweyo, kwelinye icala, enziwe ngumntu kwizityalo zeekhemikhali. Iipetrochemicals zisebenza njengezinto zokuqala. Umzekelo, i-neoprene (i-polychloroprene) yenziwa ngokuphendula i-acetylene kunye ne-hydrochloric acid. Irabha ye-Emulsion styrene – butadiene (E – SBR), esetyenziswa kakhulu kumatayara eemoto, lolunye uhlobo olunziweyo. Le nkqubo ibandakanya ukusabela kwe-polymerization phantsi kweemeko ezithile ukwenza iipolymers ezineempawu ezifana nerabha, ezithi emva koko zicutshungulwe zibe ngamasuntswana.

Ukongeza kwimithombo yerabha engafakwanga nkunkuma, irabha ephinda isetyenziswe ikwayindawo ebalulekileyo yeengceba zerabha. Izinto ezilahlwayo ezifana namatayara asetyenzisiweyo, imiphetho yerabha, kunye nezinye iimveliso zerabha ziyaqokelelwa. Ziyasikwa, zicolwe, kwaye zicutshungulwe ukuze kufunyanwe iingceba zerabha.
