NBR ikorwa cyane cyane nubushyuhe bwo hasi bwa emulsion polymerisation, hamwe no kurwanya amavuta meza, kurwanya abrasion nyinshi, kurwanya ubushyuhe bwiza no gukomera.Ingaruka zayo ni ubukonje buke buke, kwihanganira ozone, imikorere idahwitse, hamwe na elastique nkeya.NBR ikoreshwa cyane cyane mugukora ibicuruzwa bya reberi birwanya amavuta, ibinini bitandukanye birwanya amavuta, gasketi, amaboko, gupakira byoroshye, imashini yoroshye, imashini icapa, irangi, ibikoresho bya reberi, nibindi byahindutse ibikoresho byingenzi bya elastique. mumodoka, indege, peteroli, gukopera nizindi nganda.
NBR ikorwa cyane cyane nubushyuhe buke bwa emulsion polymerisation, hamwe no kurwanya amavuta meza, kwihanganira kwambara cyane, kurwanya ubushyuhe bwiza no gukomera.Ingaruka zayo ni ubukonje buke buke, kwihanganira ozone, imikorere idahwitse, hamwe na elastique nkeya.NBR ikoreshwa cyane mugukora ibicuruzwa bya reberi birwanya amavuta, gasketi zitandukanye zidashobora kwihanganira amavuta, gasketi, amaboko, gupakira byoroshye, imiyoboro yoroshye ya reberi, gucapa no gusiga irangi, ibikoresho bya reberi, nibindi byahindutse ibintu byoroshye. ibikoresho mumodoka, indege, peteroli, gukopera nizindi nganda.
NBR ifite amavuta meza yo kurwanya.Butadiene monomer irashobora gukoporora mubice bitatu bitandukanye: cis, trans hamwe na 1,2- 焼 matsinda.Imiterere ya NBR isanzwe ni 78% trans.Bitewe nuko cyano iri mumiterere ya NBR ya molekuline, kurwanya amavuta (urugero, kumavuta yubutare, ibicanwa byamazi, amavuta yinyamanswa n’ibimera, hamwe na solvets) biruta ibya reberi karemano, neoprene, na styrene-butadiene.Ugereranije nizindi reberi, NBR ifite intera nini yubushyuhe bwa serivisi, ubushyuhe bwigihe kirekire bwa serivisi ni 120oC.Hagati aho, NBR ifite ubushyuhe buke bwo kurwanya ubushyuhe, ubushyuhe bwo hasi bwikirahure bushobora kugera kuri -5oC.
NBR ifite imiti ihamye kandi ikora neza.Nkuko ubucucike bwacyo bugenda bwiyongera hamwe nibiri muri nitrile ya propylene mu miterere yabyo, umuvuduko w’ibirunga wihuta kandi imikorere yingufu zikaze ikanozwa, ariko imikorere yo kwihangana igabanuka kandi ubukonje bukonje bukaba bubi.NBR ni reberi ya semiconductor kuko cyano muri NBR ihindurwamo byoroshye n'umuriro w'amashanyarazi, bityo umutungo wa dielectric ukagabanuka.nBR irashobora kugabanywamo ibyiciro 5 bya ultra-high, high, medium-high, medium and low propylene nitrile ukurikije urwego rwibirimo ACN.Uburyo bwo kubyaza umusaruro bugabanijwe muburyo bukomeza kandi burigihe.Uburyo bukomeza bwa polymerisation bukoreshwa muburyo butandukanye hamwe nubunini bunini butanga umusaruro mukoresheje bike.Uburyo bwa polymerisation burigihe burakwiriye kubwinshi butandukanye kandi buto butanga umusaruro, ikimenyetso cya polymerisation ukoresheje umubare muto wo gukoresha cyane ubwubatsi nubwubatsi.Kugeza ubu, ntabwo ibona inzira yo gusimburana.
Nubwo NBR ifite imiterere myiza yumubiri nubukanishi hamwe nuburyo bwo gutunganya, ariko igihe kirekire muri lisansi ya acide hamwe nubushyuhe bwo hejuru (150oC) ntabwo ari byiza nkimikorere ya reberi imeze nka fluor na aside propionic aside ikonje, kubwiyi mpamvu amasosiyete yo mubudage , Amasosiyete yo muri Kanada hamwe n’amasosiyete y’Abayapani guteza imbere imikorere myiza ya hydrogenated nitrile rubber (HNBR).Mubyongeyeho, twateje imbere NBR hamwe nubukonje bukabije cyane hamwe nubuziranenge bwinshi na XNBR.

Hebei CONQI VEHICLE FITTINGS Co., Ltd nisosiyete yitangiye gukora no gukwirakwiza ibinyabiziga byo mu bwoko bwa reberi, imashini ya EPDM, ibyiciro by’ibiribwa hamwe na pvc hose nibindi bifite uburambe bukomeye bwo kubyaza umusaruro, ikoranabuhanga rigezweho kandi rifite ubumenyi bwuzuye kandi bwubumenyi.Mu mwaka wa 2009, isosiyete yarangije umusaruro w’inganda ingana na miliyoni 10.01 Yuan kandi irangiza umusoro w’ububiko ungana na 250 000 000.Bose bahujwe na OEM zirenga 30 zo mu gihugu nka Jinlong, Yutong, Ankai, na Zhongtong, hamwe n'amashami mpuzamahanga ya Volvo n'Ubuhinde, Nouvelle-Zélande, Tayilande, Tayiwani, Polonye, Isiraheli, Ubwongereza, Misiri, Espagne, Turukiya, Burezili, Singapore, Ubudage hamwe n’ibihugu n’uturere birenga 20 byabonye ibikoresho byunganira.Twisunze amahame y "gukomeza gutera imbere, kuba indashyikirwa, ubuziranenge buhebuje, no guhaza abakiriya", dufata cyane cyane ikoranabuhanga mpuzamahanga n’amakuru agezweho ku bicuruzwa, duhora dushushanya kandi dutezimbere ibicuruzwa bishya, kandi dutanga abakiriya.
