Uduce twa rubber tw’umukara ni uduce duto, dufite uruziga twakozwe mu bikoresho bya rubber byasubiwemo, ahanini bikomoka ku mapine yakoreshejwe. Uduce twa rubber dukoreshwa cyane mu nganda zitandukanye bitewe no kuramba kwabyo, koroha no kugabanya amafaranga.

Mu nganda za siporo, uduce tw’umukara twa rubber ni ingenzi cyane mu kubaka ibibuga by’ubwatsi bw’ubukorano. Dutanga urwego rw’ibanze ruhamye rwongera ubushobozi bwo gufata no gukingira ubwatsi, bigabanya ibyago byo gukomereka ku bakinnyi. Byongeye kandi, ibara ry’umukara rya duce tw’ubwatsi rifasha mu gufata ubushyuhe, bishobora kunoza aho ubusitani bushongera no kongera igihe cyo kubaho kwabwo.

Uretse siporo, utubuto tw’umukara dukoreshwa mu gusiga ibibuga, gutwikira ubutaka, ndetse no mu gukora ibikoresho bishya bya kabutike. Ubushobozi bwabyo bwo kwihanganira kwangirika no kwangirika butuma biba amahitamo meza mu bice bikunze kubamo urujya n’uruza rw’abantu benshi, nko mu nzira z’abanyamaguru n’inzira z’imihanda.

Byongeye kandi, ikoreshwa ry'udupira tw'umukara bigira uruhare mu kubungabunga ibidukikije binyuze mu kugabanya imyanda no guteza imbere kongera gukoresha amapine yakoreshejwe. Ibi ntibirinda gusa umutungo kamere ahubwo binafasha mu kugabanya ingaruka zo guta amapine ku bidukikije.
