Nucleating agentikwiranye na plastiki zuzuye za kristaline nka polyethylene na polypropilene.Muguhindura imyitwarire ya kristu ya resin, irashobora kwihutisha igipimo cya kristu, ikongera ubwinshi bwa kristu kandi igateza imbere miniaturizasi yubunini bwingano, kugirango bigabanye uruziga, bizamura umucyo nubuso bwibicuruzwa.Ikintu gishya cyongerera imbaraga kumubiri nubukanishi nkuburabyo, imbaraga zingana, gukomera, ubushyuhe bwo kugoreka ubushyuhe, kurwanya ingaruka, hamwe no kurwanya ibimera.

Nucleating agentbivuga inyongeramusaruro ikora ishobora guhindura igice cyimyitwarire ya kristu, kunoza gukorera mu mucyo, gukomera, kurabagirana hejuru, gukomera kwubushyuhe hamwe nubushyuhe bwo guhindura ubushyuhe bwibicuruzwa, kugabanya uburyo bwo kugurisha ibicuruzwa, no kunoza gutunganya no gushyira mubikorwa imikorere ibicuruzwa.

UwitekaNucleating agentikoreshwa nkumufasha wo guhindura polymer, kandi uburyo bwayo bwibikorwa ni cyane cyane: muri leta yashongeshejwe, kubera ko agent nucleating itanga nucleus isabwa, polymer ihinduka kuva nucleaux yumwimerere ihinduka nucleation ya heterogeneous, Hamwe na hamwe, kristu umuvuduko wihuta, imiterere yingano iratunganijwe, kandi nibyiza kunoza ubukana bwibicuruzwa, kugabanya uruziga, kugumya guhagarara neza kurwego rwibicuruzwa byanyuma, kubuza gukwirakwiza urumuri, kunoza umucyo nubuso bwubuso hamwe numubiri na imiterere ya polymer..Ubushakashatsi niterambere ryibikoresho bya nucleating mugihugu cyanjye byatangiye mu myaka ya za 1980, kandi hariho ubwoko bwinshi.Noneho ibintu bifatika, bihendutse kandi byubucuruzi birashobora kugabanywa cyane cyane mubintu bidafite ingufu, ibinyabuzima byangiza umubiri hamwe na polymer nucleating..Mubyongeyeho, umukozi uhindura uhindura α-kristu muburyo bwa PP muburyo bwa β-kristu isanzwe nayo ishyirwa mubikorwa nka nucleating agent.
