I-HIPS isifinyezo sesiNgisi se-polystyrene resin engamelani nokushayisana, izinto eziyinhloko zokusetshenziswa yi-styrene, enokuqina okuphezulu, ukumelana nokushayisana okuphezulu, ukuzinza kobukhulu, okulula ukuyibumba nokuyicubungula kanye nezinye izici eziningi, ingasetshenziswa kabanzi ezintweni zasekhaya, izinsimbi zomculo, amathoyizi,ukupakishwa okulahlwayo, insimu yokwakha. Ukumelana nokushayisana kwe-styrene kuphansi, futhi imikhiqizo yayo iyaphuka futhi iphuka kalula ngokushayisana. Ukwengeza izinhlayiya zerabha ze-styrene butadiene ku-styrene kungathuthukisa ngempumelelo ukumelana kwayo nokushayisana, kanti izinhlayiya zerabha ze-butadiene ezisetshenziswa kakhulu yi-butadiene, enokumelana okuhle kakhulu nokushayisana.

Okwamanje kunezindlela ezimbili zokulungiselela i-polystyrene engathinteki, okungukuthi indlela yokuxuba kanye nendlela ye-graft copolymerisation. Indlela yokuxuba, okokuqala, ingxube ye-butadiene ne-styrene ngokulingana nengxube, bese ingxube ingena ku-extruder ixubene ngokulinganayo, i-extruded thin film cooling, bese ekugcineni inqunywa ibe yi-Ama-Hipsizingcezu ezine-shear, inqubo kufanele inake kakhulu ingxube ixutshwe ngokulinganayo.

Ngendlela ye-graft copolymerisation, izinhlayiya ze-butadiene ziyancibilika ku-styrene monomer, bese kwenzeka ukusabela kwe-copolymerisation ngosizo lwe-catalyst peroxide, bese umkhiqizo we-copolymerisation ufakwa ekugcineni ku-extruder ukuze kuhlanganiswe i-granulation. Empeleni, i-HIP plastic ngokuvamile kanye ne-ABS resin yezinto ezihambisanayo, izinto ze-HIPS zishibhile kune-ABS resin, kodwa izakhiwo zemishini ziphansi kune-ABS resin, imboni yokwakha izosuselwa entengo yemakethe yokuthenga, ngakho-ke amanani epulasitiki e-HIPS ayashintshashintsha ngentengo yeI-ABS, uma amanani e-ABS ephezulu, kuzoqhuba isidingo semakethe ye-HIPS, vele, umthelela we-HIPS Amanani epulasitiki yiwona ayinhloko yizinto ze-styrene, ukunikezwa kwamanje kwe-styrene kuhlala kuzinzile, isidingo esiphansi sijwayelekile, intengo izinzile ekuqedeni. Ngokuhamba kwesikhathi, amandla okukhiqiza i-polypropylene yalo nyaka anqunyelwe, futhi ukukhiqizwa kwamadivayisi ngonyaka ozayo kulindeleke ukuthi kubambezeleke, umbono jikelele, ukunikezwa kwezimpahla akukanele, kodwa eminyakeni emibili edlule isidingo esikhuphukayo esiphansi sehlile, umbono jikelele, imakethe kulindeleke ukuthi ikhuphuke, kodwa izinzile kakhulu. Lokhu kukhombisa ukuthi uhlangothi lwezindleko alunawo amandla okushayela amahle. Eminyakeni emibili edlule, isidingo semakethe yemishini yasekhaya yaseShayina saqala ukwehla kancane kancane, kodwa ngokusekelwe kudatha enkulu, ubuchwepheshe bobuhlakani bokwenziwa, imakethe eqhubekayo ingaletha igagasi lesizini yamagagasi, elizoqhuba ngempumelelo isidingo semakethe yezinto zokusetshenziswa, uhlangothi lwesidingo sesikhathi esifushane kunzima ukuba nentuthuko enkulu, ngakho uhlangothi lwesidingo alubi.
