ʻO ke koʻokoʻo Polytetrafluoroethylene kahi mea me ke kūpaʻa kemika maikaʻi loa, ka ikaika mechanical a me ke kūpaʻa wela, a he ʻano mea polytetrafluoroethylene (PTFE). ʻO ka PTFE kahi mea synthetic me nā waiwai maikaʻi loa a hoʻohana pinepine ʻia i ka hana ʻana i nā valves, nā sila, nā ipu, nā paipu, nā insulators uwea a pēlā aku.
Hana ʻia ke koʻokoʻo PTFE mai nā ʻāpana PTFE polymerised, nona ke kūpaʻa maikaʻi loa i ka mahana kiʻekiʻe, ka pala, ka abrasion a me ka insulation, a me ke kūpaʻa kiʻekiʻe loa i ka ʻelemakule a me ke kūpaʻa i ka ʻaila a me nā solvents. No laila, kūpono loa ke koʻokoʻo PTFE no ka hoʻohana ʻana ma ke ʻano he sila, nā mea hoʻopihapiha valve, nā insulators conductive, nā conveyors, a me nā mea ʻē aʻe ma nā kahua o ka kemika, lāʻau lapaʻau, nā mea uila, ka mana uila, ka aerospace a me ka hana mīkini.
Eia kekahi, ʻaʻole wale ke koʻokoʻo PTFE i ke kūpaʻa maikaʻi loa i ka pala, akā he kūpaʻa wela kiʻekiʻe hoʻi, hiki ke hoʻohana ʻia ke koʻokoʻo PTFE a hiki i ka mahana kiʻekiʻe o 260 ℃. I ka manawa like, loaʻa iā ia nā waiwai uila maikaʻi loa, no laila hoʻohana nui ʻia ke koʻokoʻo PTFE i ka hana ʻana i nā uea a me nā kaula like ʻole, nā ʻāpana insulating, nā panela kristal wai a me nā ʻāpana uila ʻē aʻe.
He mea polymer ka PTFE rod me nā ʻano hoʻohana like ʻole a me ka hana maikaʻi loa, a he mau noi nui ia ma nā ʻoihana like ʻole.
