I puta mai te takirere pōro i muri i te Pakanga Tuarua o te Ao. Ahakoa i ahu mai te hanganga o te takirere pōro i te tīmatanga o te rautau 20, kāore i oti i tēnei patent hanganga āna mahi hokohoko nā ngā herenga i roto i te umanga rauemi me te umanga tukatuka mīhini. I hangaia e DuPont i te United States he kirihou polytetrafluoroethylene (PTFE) rauemi polymer teitei tae noa ki te tau 1943. He painga tēnei momo rauemi o te kaha kume me te kaha pēhi, te elastoplasticity, ngā āhuatanga whakahinuhinu-ake pai me te ātete waikura pai, he tino pai hei rauemi hiri me te tino pono o te pānga hiri. Hei tāpiri, ka taea te hanga i tētahi pōro he porowhita teitei me te mutunga mata pai hei mema kati o te takirere pōro nā te whanaketanga o ngā mīhini huri pōro. Ka uru mai tētahi momo takirere hou me te poka katoa me te nekehanga koki hurihuri 90° ki te mākete takirere, e kukume ana i te aro nui. Ko ngā hua takirere tuku iho pērā i ngā takirere aukati, ngā takirere kuaha, ngā takirere mono me ngā takirere pūrerehua ka whakakapia mārire e ngā takirere pōro, ā, he nui te whakamahinga o ngā takirere pōro, mai i ngā diameter iti ki ngā diameter nui, te pēhanga iti ki te pēhanga teitei, te pāmahana noa ki te pāmahana teitei, te pāmahana teitei ki te pāmahana iti. I tēnei wā, kua eke te diameter mōrahi o te takirere pōro ki te 60 Inihi, ā, ko te pāmahana iti rawa ka eke ki te pāmahana hauwai wai -254℃. Ko te pāmahana teitei rawa ka eke ki te 850 ki te 900℃. Nā ēnei katoa ka pai ngā takirere pōro mō ngā momo pāpāho katoa, ā, koinei te momo takirere tino whai hua.

Ka taea te wehewehe i ngā takirere pōro ki ngā takirere pōro mānu me ngā takirere pōro trunnion i runga i te hanganga.

Ka taea te whakarōpū i ngā takirere pōro ki ngā takirere pōro whakauru o runga me ngā takirere pōro whakauru taha. Ka taea hoki te wehewehe i ngā takirere pōro whakauru taha ki ngā takirere pōro kotahi-wahi, ngā takirere pōro rua-wahi me ngā takirere pōro toru-wahi, e ai ki te hanganga o te tinana takirere. He mea whakauru ngā tinana takirere o ngā takirere pōro kotahi-wahi; ko ngā takirere pōro rua-wahi he tinana takirere matua me ngā tinana takirere āwhina, ā, ko ngā takirere pōro toru-wahi he tinana takirere matua kotahi me ngā tinana takirere āwhina e rua.

E ai ki te rauemi hiri o te takirere, ka taea te whakarōpū i ngā takirere pōro ki ngā takirere pōro hiri ngohengohe me ngā takirere pōro hiri mārō. Ko ngā rauemi hiri o ngā takirere pōro hiri ngohengohe he rauemi polymer teitei pērā i te polytetrafluoroethylene (PTFE), te polytetrafluoroethylene whakakaha me te nairona me te rapa. Ko ngā rauemi hiri o ngā takirere pōro hiri mārō he konganuku.
