muri rusange, ifu ya polymer isubirwamo izwiho kuzamura imbaraga nigihe kirekire cya minisiteri. Ni ukubera ko ifu ya polymer ikora nkibikoresho bifasha guhuza ibice bya minisiteri, bigatera imbere guhuza hamwe no gufatira hamwe ibikoresho. Byongeye kandi, ifu ya polymer irashobora kandi kongera imbaraga zo kurwanya amazi no guhinduka kwa minisiteri, bigatuma irwanya gucika nubundi buryo bwangiritse. Muri rusange, gukoresha ifu ya polymer isubirwamo irashobora gufasha kurema imbaraga zikomeye, ziramba, kandi zidashobora gukomera zikwiranye nubwubatsi butandukanye bwo kubaka.
