Ngesikhathi sokukhiqiza, lapho ukuncibilika kwepulasitiki kufakwa emgodini wesikhunta ngaphansi kokushisa okuphezulu kanye nokucindezela okuphezulu bese kubumba ngaphansi kokucindezela, lapho izinga lokushisa lehla, ukuncibilika kuyaphola bese kuqina kube yingxenye yepulasitiki. Usayizi wengxenye yepulasitiki mncane kunowesikhala sesikhunta, okubizwa ngokuthi ukufinyeza. Izizathu eziyinhloko zokufinyeza yilezi ezilandelayo. Lapho kwenziwa ipulasitiki, ubukhulu bezingxenye ezahlukene zamasango esikhunta buhlukile. Isango elikhulu lisiza ukwandisa ingcindezi yesikhala, lenze isikhathi sokuvala sesango, futhi lenze kube lula ukugeleza kokuncibilika okwengeziwe emgodini, ngakho-ke ubuningi bengxenye yepulasitiki nabo bukhulu, ngaleyo ndlela kuncishiswe izinga lokufinyeza, ngaphandle kwalokho kuzokhulisa izinga lokufinyeza.
Izinguquko esakhiweni samakhemikhali sesikhunta sepulasitiki ngesikhathi senqubo yokukhiqiza. Amanye amapulasitiki ashintsha isakhiwo sawo samakhemikhali ngesikhathi senqubo yokubumba. Isibonelo, kumapulasitiki okusetha ukushisa, i-molecule ye-resin iyashintsha kusuka esakhiweni esiqondile iye esakhiweni esifana nomzimba. Isisindo sevolumu sesakhiwo esifana nomzimba sikhulu kunesakhiwo esiqondile, ngakho-ke ivolumu yaso iyonke iyafinyezwa, okuholela ekufinyezweni. Izingxenye zepulasitiki ezinciphile ezinobukhulu obufanayo bodonga zipholiswa ngokushesha emgodini wesikhunta, futhi izinga lokufinyezwa livame ukuba lincane kakhulu ngemva kokufinyezwa. Isikhathi eside sokuba ingxenye yepulasitiki ebanzi enobukhulu obufanayo bodonga iphole emgodini, kulapho ukufinyezwa okukhulu ngemva kokufinyezwa. Uma ubukhulu bengxenye yepulasitiki buhlukile, kuzoba nezinga elithile lokufinyezwa ngemva kokufinyezwa. Uma kwenzeka ushintsho olungazelelwe kangaka ekufinyezweni kodonga, izinga lokufinyezwa nalo lizoshintsha ngokuzumayo, okuholela ekucindezelekeni okukhulu kwangaphakathi.
Ukucindezeleka okusele kuyashintsha. Lapho izingxenye zepulasitiki zibunjwa, ngenxa yethonya lokucindezela kokubumba kanye namandla okucheba, i-anisotropy, ukuxubana okungalingani kwezithasiselo kanye nokushisa kwesikhunta, kuba nokucindezeleka okusele ezingxenyeni zepulasitiki ezibunjiwe, futhi ukucindezeleka okusele kuzoncipha kancane kancane futhi kuphinde kusabalale, okuholela ezingxenyeni zepulasitiki. Ukufinyeza futhi ngokuvamile kubizwa ngokuthi i-post-shortening.
