Styrene ni ibikoresho byingenzi byamazi yimiti.Ni hydrocarubone ya monocyclic aromatic ifite urunigi rwa alkene kandi ikora sisitemu ya conjugate hamwe nimpeta ya benzene.Numunyamuryango woroheje kandi wingenzi wa hydrocarbone ya aromatic idahagije.Styrene ikoreshwa cyane nkibikoresho fatizo byo gukora ibisigazwa bya sintetike na reberi.
Styrene ni ibikoresho byingenzi biva mu miti y’ibanze, bya hydrocarubone ya monocyclic aromatic hydrocarubone ifite urunigi rwa alkene kandi ikora sisitemu ihujwe nimpeta ya benzene.Ni hydrocarubone ya hydrocarbon styrene idahagije "itwara amakara ya peteroli kandi ihuza reberi na plastiki", kandi ni ibikoresho by'ibanze fatizo nganda nganda zikomoka kuri peteroli.Inzira yo hejuru ya styrene ni benzene na Ethylene, kandi epfo na ruguru iratatanye.Ibicuruzwa byingenzi birimo birimo ifuro rya polystirene, polystirene, resin ya ABS, reberi yubukorikori, polyester idahagije hamwe na styrene copolymers, kandi itumanaho rikoreshwa cyane mubicuruzwa bya plastiki na sintetike.
Umwaka wa 2010 ku isi ubushobozi bwo kongera umusaruro wa styrene, ku buryo bukabije iyo kwiyongera kwa toni zigera kuri miliyoni 2.78 z’ubushobozi bw’umusaruro, ubwiyongere bw’umusaruro bugera kuri 10%, cyane cyane ku isi cyane cyane mu Bushinwa ku bicuruzwa bikomoka kuri styrene (itumanaho rikoreshwa mu bikoresho byo mu rugo, ibinyabiziga na inganda zubaka inganda) ikoreshwa, mu 2009 na 2010, Ubushinwa bukenera styrene bwari hejuru ya 15%.Nyuma ya 2010, umuvuduko w’ubwiyongere bw’ubushobozi bwa styrene ku isi wagabanutse buhoro buhoro, kandi mu mpera za 2017, ubushobozi bwa styrene ku isi bwageze kuri toni miliyoni 33.724.
Ubushobozi bwa styrene ku isi bwibanda cyane muri Aziya y'Uburasirazuba, Amerika y'Amajyaruguru n'Uburayi bw'Uburengerazuba, bingana na 78.9% by'ubushobozi bwa styrene ku isi.Byongeye kandi, akarere ka Aziya-pasifika kangana na 52% byubushobozi bwa styrene ku isi.
Ibisabwa hasi ya styrene biratandukanye, kandi ibicuruzwa byanyuma nibicuruzwa bya plastiki na reberi yubukorikori.
Uhereye ku isi yose ikenera styrene mu 2016, 37.8% styrene ikoreshwa kuri polystirene, 22.1% kuri polystirene ifuro ifuro, 15.9% kuri ABS resin, 9.9% kuri reberi ya styrene butadiene, 4.8% kuri resin idahagije, nibindi.
Ubwiyongere bw'umusaruro mushya mu gihugu, Ubushinwa bwinjira mu mahanga ndetse no gutumiza mu mahanga byagabanutse cyane mu myaka yashize.
Nk’uko imibare ya gasutamo ibigaragaza, mu 2018, ibihugu by’Ubushinwa byinjira cyane mu mahanga ni Arabiya Sawudite, Ubuyapani, Koreya yepfo, Singapuru, n’ibindi. isoko nini yo gutumiza mu mahanga.
Kuva ku ya 23 Kamena 2018, Minisiteri y’ubucuruzi y’Ubushinwa yashyizeho imisoro yo kurwanya ibicuruzwa biva kuri 3.8% kugeza kuri 55.7% kuri styrene yatumijwe muri Repubulika ya Koreya na Amerika mu gihe cy’imyaka itanu, bigatuma igabanuka rikabije. igipimo cy’ibicuruzwa biva mu Bushinwa biva muri Repubulika ya Koreya mu gice cya kabiri cy’umwaka wa 2018, aho Arabiya Sawudite n’Ubuyapani bibaye ibihugu nyamukuru biva mu mahanga.
Hamwe n’umusaruro mwinshi w’inganda zikorera mu gihugu, umubare munini w’ibikorwa bishya bya styrene bizashyirwa mu bikorwa mu Bushinwa mu gihe kiri imbere.
Mugihe cy "gahunda yimyaka 13 yimyaka 5", Ubushinwa bwateje imbere gahunda yo gutunganya abikorera mu gihugu no gutunganya peteroli.Kugeza ubu, Hengli, Sheng hamwe n’indi miriyoni icumi yo gutunganya no gutunganya peteroli y’imiti byemejwe ko byinjira mu gihe cy’ubwubatsi, kandi inganda nini nini zitunganya ibikomoka kuri peteroli n’inganda zishyigikira ibikoresho byo mu bwoko bwa styrene.
