CTBN ke polymer e ngata haholo e kopanyang thepa ea butadiene le acrylonitrile. E sebelisoa haholo joalo ka toughener ho li-epoxy resin, thermoplastics le lisebelisoa tse ling ho matlafatsa ts'ebetso ea tsona e tšoarellang, ho hanyetsa tšusumetso le ho fetoha habonolo. Elastomer ena e fumaneha ka limaraka tse fapaneng tse nang le boima bo fapaneng ba limolek'hule le likahare tsa carboxyl ho fana ka litharollo tse ikhethileng tse ipapisitseng le thepa e hlokahalang.
E 'ngoe ea thepa ea bohlokoa eaCTBN ke ho feto-fetoha ha eona hantle ha mocheso o tlase. E lula e tenyetseha ebile e saroloha esita le mochesong o batang haholo, e etsa hore e be sebaka se loketseng tikolohong ea arctic kapa lits'ebetsong moo ho lebelletsoeng ho pepesehela mocheso o tlase. Thepa ena e tiisa hore lisebelisoa tse nang le CTBN li boloka botšepehi le ts'ebetso ea tsona esita le tlas'a maemo a thata.
Ntle le moo, CTBN e na le mamarelo a matle ho lisebelisoa tse fapaneng, ho kenyeletsoa litšepe, lipolasetiki le li-composite. Thepa ena ea sekhomaretsi e etsa hore e be tlatsetso ea bohlokoa ea ho roala, likhomaretsi le li-sealants, ho ntlafatsa matla a bona a tlamo le bophelo ba ts'ebeletso. Ho tsamaellana ha CTBN le lisebelisoa tse fapaneng ho eketsa molemo oa eona liindastering tse fapaneng.
Ho feta moo, CTBN e tsejoa ka ho hanyetsa matla a eona a matla. E monya le ho qhala matla a ts'usumetso, e thibela lisebelisoa ho senya le ho senya. Thepa ena e bohlokoa haholo lits'ebetsong moo ts'ebetso le ts'ebetso ea ho hanyetsa li leng bohlokoa haholo, joalo ka sefofane, likoloi le lisebelisoa tsa lipapali. Ka ho kenyelletsa CTBN lisebelisoa tsena, bahlahisi ba ka etsa bonnete ba hore lihlahisoa tsa bona li ka mamella maemo a thata a tšebeletso.
Sebaka se seng mooCTBN excels ke ho fana ka boima le elasticity ho li-polymer tse thata. Ka ho kopanya CTBN le li-polymer tsa thermoset tse kang li-epoxy resin, metsoako e hlahisoang e bontša ho tiea ho matlafalitsoeng le ho hanyetsa crack. Thepa ena e na le molemo o moholo likarolong tsa tlhahiso tse kang mechini e boima, likarolo tsa meralo le li-insulator tsa motlakase.
Motsoako o ikhethang oa thepa e fanoang ke CTBN e etsa hore e be thepa ea bohlokoa likarolong tse sa tšoaneng. Baenjineri ba sepakapaka ba sebelisa CTBN bakeng sa litiiso tsa elastomeric, li-gaskets le likaroloana tse fokotsang ho sisinyeha. Indastering ea likoloi, CTBN e sebelisoa ho li-absorbers, li-coatings tse ka tlas'a 'mele le likarolo tsa tsamaiso ea mafura.CTBNe boetse e sebelisoa haholo tlhahisong ea thepa ea lipapali tsa boemo bo holimo, ho kenyelletsa le libolo tsa kolofo, lithupa tsa hockey le lieta tsa liatleletiki.
Ka kakaretso, CTBN (carboxyl-terinated butadiene acrylonitrile) ke elastomer e nang le mefuta e mengata e ntlafatsang thepa ea thepa. Ka mokhoa o babatsehang oa ho feto-fetoha ha mocheso o tlaase, ho khomarela, ho hanyetsa tšusumetso le ho tiea, CTBN e sebelisoa haholo liindastering tse kang sefofane, likoloi le lipapali. Ha theknoloji e ntse e tsoela pele le tlhokahalo ea lisebelisoa tse phahameng tsa ts'ebetso e ntse e eketseha, CTBN e ka 'na ea tsoela pele ho phetha karolo ea bohlokoa ho ntlafatsa ho tšepahala le ho tšoarella ha lihlahisoa tse sa tšoaneng.
Re barekisi ba ka holimo ba CTBN Chaena, re fana ka mefuta e fapaneng ea CTBN le lintho tse ling tse amanang le tsona joalo kaHTPB,ATBN,ATPB , joalo-joalo. Khabareng re ka etsa lipatlisiso le ho hlahisa CTBN e ncha ho latela tlhoko e khethehileng ea bareki ba rona.
