He pūhui tino maha ngā mahi a te CTBN e whakakotahi ana i ngā āhuatanga o te butadiene me te acrylonitrile. He whānuitia te whakamahinga hei whakapakari i roto i ngā kapia epoxy, ngā kirihou wera me ētahi atu rauemi hei whakarei ake i tōna pakari, tōna ātete ki te pānga me te ngāwari. Kei te wātea tēnei elastomer i roto i ngā momo taumata me ngā taumaha ngota ngota me ngā ihirangi carboxyl rerekē hei whakarato i ngā otinga ritenga i runga i ngā āhuatanga e hiahiatia ana.
Ko tētahi o ngā āhuatanga matua o CTBNKo tōna tino ngāwari ki te pāmahana iti. Ka noho ngāwari tonu, ka pūmau hoki te ngāwari ahakoa i ngā pāmahana tino makariri, ā, he mea tino pai mō ngā taiao ātiki, mō ngā tono rānei e tika ana kia pāngia e ngā pāmahana iti. Mā tēnei āhuatanga ka mau tonu te pono me te mahi a ngā rauemi kei roto ko te CTBN ahakoa i raro i ngā āhuatanga uaua.
Hei tāpiritanga, he tino pai te piri o te CTBN ki ngā momo rauemi, tae atu ki ngā konganuku, ngā kirihou me ngā mea whakakotahi. Nā tēnei āhuatanga piri ka waiho hei tāpiringa nui ki ngā paninga, ngā piripiri me ngā hiri, ka whakapai ake i te kaha o te piri me te roa o te mahi. Ko te hototahi o te CTBN ki ngā momo rauemi ka whakarei ake i tōna whai huatanga i roto i ngā ahumahi rerekē.
Hei tāpiritanga, e mōhiotia ana a CTBN mō tōna ātete pai ki ngā pānga. Ka mimiti, ka horahia hoki te kaha o te pānga, ka ārai i ngā rauemi kei pakaru, kei pakaru. He tino whai hua tēnei āhuatanga i roto i ngā tono e tino hira ana te ātete ki ngā pānga me ngā pānga, pērā i te rererangi, te motuka, me ngā taputapu hākinakina. Mā te whakauru i te CTBN ki roto i ēnei rauemi, ka taea e ngā kaihanga te whakarite kia taea e ā rātou hua te tu atu ki ngā āhuatanga ratonga uaua.
Tētahi atu wāhi kei reira CTBNKo tā te hiranga he whakarato i te pakari me te ngāwari ki ngā pūmua pakari. Mā te whakaranu i te CTBN me ngā pūmua thermoset pēnei i te kapia epoxy, ka whakaatuhia e ngā hiato hua te pakari me te ātete ki te pakaru. He tino whai hua tēnei āhuatanga i roto i te hanga waahanga pēnei i te mīhini taumaha, ngā huānga hanganga me ngā ārai hiko.
Nā te huinga ahurei o ngā āhuatanga e tukuna ana e CTBN, he mea nui tēnei rauemi i roto i ngā momo mara. Ka whakamahia e ngā miihini rererangi te CTBN mō ngā hiri elastomeric, ngā gasket me ngā wāhanga whakamāmā wiri. I roto i te umanga motuka, ka whakamahia te CTBN i roto i ngā mea mimiti pānga, ngā paninga o raro i te tinana me ngā wāhanga pūnaha wahie.CTBNe whakamahia whānuitia ana hoki i roto i te hanga taonga hākinakina mahi teitei, tae atu ki ngā pōro korowha, ngā rākau hōkī me ngā hū hākinakina.
Hei whakarāpopototanga, he elastomer maha-whakamahinga te CTBN (carboxyl-terminated butadiene acrylonitrile) e whakarei ake ana i ngā āhuatanga o te rauemi. Nā tōna ngāwari pai ki te pāmahana iti, te piri, te ātete pānga me te pakari, e whakamahia whānuitia ana te CTBN i roto i ngā ahumahi pēnei i te rererangi, te motuka me ngā hākinakina. I te whanaketanga o te hangarau me te piki haere o te tono mō ngā rauemi mahi teitei, tera pea ka whai wāhi tonu te CTBN ki te whakapai ake i te pono me te roa o te mau o ngā momo hua.
