NBR makamaka opangidwa ndi otsika kutentha emulsion polymerization njira, ndi mafuta kukana kwambiri, mkulu abrasion kukana, wabwino kukana kutentha ndi adhesion amphamvu.Zoyipa zake ndi kusakanizidwa bwino kwa kutentha, kutsika kwa ozoni, kusagwira bwino ntchito kwa insulation, komanso kutsika pang'ono.NBR imagwiritsidwa ntchito makamaka popanga mankhwala a rabara osamva mafuta, ma gaskets osiyanasiyana osamva mafuta, ma gaskets, manja, zonyamula zofewa, payipi yofewa, zosindikizira ndi zopaka utoto, zida za mphira, ndi zina. Zakhala zofunikira zotanuka. mu zamagalimoto, ndege, mafuta, kukopera ndi mafakitale ena.
NBR makamaka opangidwa ndi otsika kutentha emulsion polymerization njira, ndi mafuta kukana kwambiri, mkulu kuvala kukana, wabwino kukana kutentha ndi adhesion amphamvu.Zoyipa zake ndi kusakanizidwa bwino kwa kutentha, kutsika kwa ozoni, kusagwira bwino ntchito kwa insulation, komanso kutsika pang'ono.NBR imagwiritsidwa ntchito makamaka popanga zinthu za rabara zosagwira mafuta, ma gaskets osiyanasiyana osamva mafuta, ma gaskets, manja, zonyamula zofewa, machubu amphira ofewa, zosindikizira ndi zopaka utoto, zida za mphira, ndi zina.

NBR ili ndi kukana mafuta bwino.Butadiene monomer imatha kuphatikizidwa m'magulu atatu osiyanasiyana: magulu a cis, trans ndi 1,2-焼.Mawonekedwe a NBR ali pafupifupi 78% trans.Chifukwa cha kukhalapo kwa cyano mu dongosolo la molekyulu ya NBR, kukana kwamafuta (mwachitsanzo, mafuta amchere, mafuta amadzimadzi, mafuta anyama ndi masamba, ndi zosungunulira) ndikwabwino kuposa mphira wachilengedwe, neoprene, ndi rabara ya styrene-butadiene.Poyerekeza ndi ma rubbers ena, NBR ili ndi kutentha kosiyanasiyana kwa utumiki, kutentha kwake kwa nthawi yayitali ndi 120oC.Pakadali pano, NBR ili ndi kukana kwa kutentha kochepa, kutentha kotsika kwambiri kwa galasi kumatha kufika -55oC.
NBR ili ndi kukhazikika kwamankhwala abwino komanso magwiridwe antchito abwino.Pamene kachulukidwe kake kakuwonjezeka ndi zomwe zili mu propylene nitrile m'mapangidwe ake, kuthamanga kwa vulcanization kumafulumizitsa ndipo mphamvu yogwira ntchito imakhala bwino, koma kupirira kumachepa ndipo kuzizira kumakhala kosauka.NBR ndi rabara ya semiconductor chifukwa cyano mu NBR imasinthidwa mosavuta ndi malo amagetsi, motero katundu wa dielectric amachepa.nBR ikhoza kugawidwa m'magulu a 5 a nitrile apamwamba kwambiri, apamwamba, apakati, apakati ndi otsika a propylene nitrile malinga ndi msinkhu wa ACN.Njira yopanga imagawidwa kukhala njira yopitilira komanso yapakatikati ya polymerization.Njira yopitilira ma polymerization nthawi zambiri imagwiritsidwa ntchito pamitundu yochepa komanso kupanga kuchuluka kwakukulu komwe kumagwiritsidwa ntchito pang'ono.Zopakatikati polymerization njira ndi oyenera Mipikisano zosiyanasiyana ndi yaing'ono mtanda kupanga, polymerization chizindikiro ntchito ochepa mowa mkulu wa zomangamanga ndi zomangamanga.Pakalipano, sichiwona chizolowezi chosinthana.
Ngakhale NBR ali ndi katundu wabwino kwambiri thupi ndi makina ndi ntchito processing, koma kwa nthawi yaitali mu acidic mafuta ndi kutentha (150oC) chilengedwe si bwino monga ntchito fluorine ngati mphira ndi propionic acid ozizira mphira, pachifukwa ichi makampani Germany. , Makampani aku Canada ndi makampani aku Japan kuti apange mphira wabwino kwambiri wa hydrogenated nitrile rubber (HNBR).Kuphatikiza apo, tapanganso NBR yokhala ndi kuzizira kwambiri komanso kuyera kwambiri komanso XNBR.
