CTBN ke polymer e feto-fetohang haholo e kopanyang thepa ea butadiene le acrylonitrile. E sebelisoa haholo e le sesebelisoa sa ho tiisa li-resin tsa epoxy, thermoplastics le lisebelisoa tse ling ho ntlafatsa ho tšoarella ha tsona, ho hanyetsa tšusumetso le ho tenyetseha. Elastomer ena e fumaneha ka mefuta e fapaneng ea limaraka tse nang le boima bo fapaneng ba limolek'hule le litaba tsa carboxyl ho fana ka litharollo tse ikhethileng ho latela thepa e hlokahalang.
E 'ngoe ea litšobotsi tsa bohlokoa tsa CTBNke ho tenyetseha ha yona ho babatsehang mochesong o tlase. E dula e tenyetseha ebile e tenyetseha esita le mochesong o batang haholo, e leng se etsang hore e be ntle bakeng sa dibaka tsa arctic kapa ditshebediso moo ho lebellwang ho pepesehela mocheso o tlase. Thepa ena e netefatsa hore thepa e nang le CTBN e boloka botsitso le tshebetso ya yona esita le maemong a thata.
Ho phaella moo, CTBN e na le kgomarelo e ntle haholo ho mefuta e fapaneng ya thepa, ho kenyeletswa le tshepe, dipolasetiki le dikompositi. Thepa ena ya kgomarelo e etsa hore e be sehlomathiso sa bohlokwa ho dikobo, dikhomaretsi le di-sealant, e ntlafatsang matla a tsona a kgomarelo le bophelo ba tshebeletso. Ho tsamaellana ha CTBN le mefuta e fapaneng ya thepa ho ntlafatsa thuso ya yona diindastering tse fapaneng.
Ho phaella moo, CTBN e tsebahala ka ho hanyetsa ha yona ho hoholo ha tshusumetso. E monya le ho hasanya matla a tshusumetso, e thibela thepa ho petsoha le ho robeha. Thepa ena e bohlokwa haholo ditshebedisong moo tshusumetso le khanyetso ya tshusumetso di leng bohlokwa, jwalo ka difofane, dikoloi le disebediswa tsa dipapadi. Ka ho kenyelletsa CTBN disebeding tsena, bahlahisi ba ka netefatsa hore dihlahiswa tsa bona di kgona ho mamella maemo a thata a tshebeletso.
Sebaka se seng moo CTBNexcels e fana ka ho tiea le ho tenyetseha ho li-polymer tse thata. Ka ho kopanya CTBN le li-polymer tsa thermoset tse kang li-resin tsa epoxy, metsoako e hlahisoang e bontša ho tiea ho eketsehileng le ho hanyetsa mapetso. Thepa ena e molemo haholo tlhahisong ea likarolo tse kang mechine e boima, likarolo tsa sebopeho le li-insulator tsa motlakase.
Motsoako o ikhethang oa thepa e fanoang ke CTBN o etsa hore e be thepa ea bohlokoa masimong a fapaneng. Baenjiniere ba lifofane ba sebelisa CTBN bakeng sa litiiso tsa elastomeric, li-gasket le likarolo tse thibelang ho thothomela. Indastering ea likoloi, CTBN e sebelisoa ho li-ammover tse amang matla, liphahlo tse ka tlas'a 'mele le likarolo tsa sistimi ea mafura.CTBNe boetse e sebelisoa haholo tlhahisong ea thepa ea lipapali e sebetsang hantle, ho kenyeletsoa libolo tsa kolofo, lithupa tsa hockey le lieta tsa lipapali.
Ka bokhutšoanyane, CTBN (carboxyl-terminated butadiene acrylonitrile) ke elastomer e feto-fetohang e ntlafatsang thepa ea thepa. Ka ho tenyetseha ha eona ho hoholo ha mocheso o tlase, ho khomarela, ho hanyetsa tšusumetso le ho tiea, CTBN e sebelisoa haholo liindastering tse kang tsa lifofane, likoloi le lipapali. Ha theknoloji e ntse e tsoela pele le tlhoko ea thepa e sebetsang hantle e ntse e eketseha, CTBN e kanna ea tsoela pele ho bapala karolo ea bohlokoa ho ntlafatseng botšepehi le ho tšoarella ha lihlahisoa tse fapaneng.
Re mofani ea ka sehloohong oa CTBN Chaena, re fana ka mefuta e fapaneng ea CTBN le lintho tse ling tse amanang le eona joalo ka HTTPB, ATBN, ATTB, jj.. ha re ntse re le moo re ka etsa lipatlisiso le ho ntshetsa pele CTBN e ncha ho latela tlhoko e ikgethang ya bareki ba rona.
