Nucleating wothandizirandi oyenera mapulasitiki osakwanira crystalline monga polyethylene ndi polypropylene.Posintha khalidwe la crystallization la utomoni, limatha kufulumizitsa mlingo wa crystallization, kuonjezera kachulukidwe ka crystallization ndi kulimbikitsa miniaturization ya kukula kwa tirigu, kuti mufupikitse kuzungulira kuumba, kupititsa patsogolo kuwonekera ndi pamwamba pa mankhwala.Chowonjezera chatsopano cha zinthu zakuthupi ndi zamakina monga gloss, kulimba kwamphamvu, kulimba, kutentha kupotoza kutentha, kukana kwamphamvu, komanso kukana kukwawa.

Nucleating wothandiziraamatanthauza chowonjezera chamankhwala chomwe chingasinthe gawo la machitidwe a crystallization, kusintha kuwonekera, kukhazikika, gloss pamwamba, kulimba kwamphamvu ndi kutentha kwamafuta azinthu, kufupikitsa kuzungulira kwa chinthucho, ndikuwongolera magwiridwe antchito ndikugwiritsa ntchito mankhwala.

Thenucleating wothandiziraamagwiritsidwa ntchito monga kusinthidwa wothandizira wa polima, ndi limagwirira ntchito zake makamaka: mu dziko losungunuka, popeza nucleating wothandizira amapereka chofunika kristalo phata, ndi polima kusintha kuchokera original homogeneous nucleation kwa heterogeneous nucleation, potero, ndi crystallization. liwiro ndi imathandizira, kapangidwe ka tirigu ndi woyengedwa, ndipo n'kopindulitsa kusintha kuuma kwa mankhwala, kufupikitsa akamaumba mkombero, kusunga dimensional bata la chomaliza mankhwala, ziletsa kuwala kubalalika, kusintha mandala ndi pamwamba gloss ndi thupi ndi makina katundu wa polima.(monga stiffness, modulus), kufupikitsa processing mkombero, etc. Monga gulu lofunika la nucleating wothandizira, ntchito yaikulu ya mandala wothandizira ndi kusintha kuwala zotsatira za polima.Kafukufuku ndi chitukuko cha ma nucleating agents m'dziko langa anayamba mu 1980s, ndipo pali mitundu yambiri.Tsopano zothandiza, zotsika mtengo komanso zamalonda zopangira nucleating zitha kugawidwa m'magulu a nucleating, organic nucleating agents ndi polima nucleating agents..Kuonjezera apo, wothandizira kusintha omwe amasintha mawonekedwe a α-crystal mu PP ku mawonekedwe a β-crystal nthawi zambiri amatchulidwanso ngati nucleating agent.
