Uduce tw’umukara karemano dukomoka ahanini kuri latex y’igiti cya Hevea brasiliensis, gikomoka muri Brezili ariko ubu gihingwa cyane mu bihugu byo muri Aziya y’Amajyepfo y’uburasirazuba nka Maleziya na Indoneziya. Iyo igiti giciwe, latex, amazi y’umweru asa n’amata, irasohoka. Iyi latex irimo amazi agera kuri kimwe cya gatatu n’igice cya gatatu cy’umukara mu gice cy’umukara cya colloidal. Utu duce dukorerwa mu turemangingo twihariye twa latex - dukora twitwa laticifers. Rubber muri latex ni polymer ya isoprene, ifite formula ya chimique (C₅H₈)ₙ. Nyuma yo gukusanya, latex ikorerwa isuku kugira ngo ivange kandi itunganye uduce tw’umukara.

Ku rundi ruhande, uduce twa rubber twakozwe n'abantu twakozwe mu bimera bya shimi. Ibinyabutabire bya peteroli ni ibikoresho byo gutangira. Urugero, neoprene (polychloroprene) ikorwa hifashishijwe acetylene na aside hydrochloric. Emulsion styrene – butadiene rubber (E – SBR), ikoreshwa cyane mu mapine y'imodoka, ni ubundi bwoko bwa sintetike. Iyi nzira ikubiyemo uburyo bwa polymerization mu bihe runaka kugira ngo hakorwe polymer zifite imiterere nk'iya rubber, hanyuma zigatunganywamo uduce.

Uretse amasoko ya kabutura itarakoreshwa, kabutura ikoreshwa mu kongera gukoreshwa nayo ni inkomoko ikomeye y’uduce twa kabutura. Imyanda nk'amapine yakoreshejwe, imipira ya kabutura, n'ibindi bicuruzwa bya kabutura birakusanywa. Birashwanyaguzwa, bigasigwa, bigatunganywa kugira ngo haboneke uduce twa kabutura.
