ʻO ke ʻano o kahi kiwikā pōpō ma hope o ke Kaua Honua ʻElua. ʻOiai ua hoʻi ka hana ʻana o kahi kiwikā pōpō i ka hoʻomaka ʻana o ke kenekulia 20, ua hiki ʻole i kēia palapala hoʻopaʻa kūkulu ke hoʻopau i kāna mau ʻanuʻu kālepa ma muli o nā palena i ka ʻoihana mea a me ka ʻoihana hana mīkini. Ua hana ʻo DuPont ma ʻAmelika Hui Pū ʻIa i kahi mea polymer kiʻekiʻe polytetrafluoroethylene (PTFE) plastic a hiki i ka makahiki 1943. Loaʻa i kēia ʻano mea nā pono o ka ikaika tensile a me ka compressive, kekahi elastoplasticity, nā waiwai lubricating ponoʻī maikaʻi a me ke kūpaʻa maikaʻi loa i ka corrosion, kahi mea kūpono loa e like me kahi mea sila a he hopena sila hilinaʻi loa. Eia kekahi, hiki ke hana ʻia kahi pōpō me ke kiʻekiʻe o ka poepoe a me ka hoʻopau ʻana o ka ʻili maikaʻi ma ke ʻano he lālā pani o kahi kiwikā pōpō ma muli o ka hoʻomohala ʻana o nā mīkini wili pōpō. Ke komo nei kahi ʻano kiwikā hou me ka bore piha a me ka huakaʻi angular 90° i ka mākeke kiwikā, e huki ana i ka nui o ka nānā. Hoʻololi mālie ʻia nā huahana kiwikā kuʻuna e like me nā kiwikā hoʻōki, nā kiwikā puka, nā kiwikā plug a me nā kiwikā butterfly e nā kiwikā pōpō, a hoʻohana nui ʻia nā kiwikā pōpō, mai nā anawaena liʻiliʻi a i nā anawaena nui, ke kaomi haʻahaʻa a i ke kaomi kiʻekiʻe, ka mahana maʻamau a i ka mahana kiʻekiʻe, ka mahana kiʻekiʻe a i ka mahana haʻahaʻa. I kēia manawa, ua hiki ke anawaena kiʻekiʻe o ka kiwikā pōpō i 60 ʻīniha, a hiki i ka mahana haʻahaʻa loa ke hiki i ka mahana hydrogen wai -254℃. Hiki i ka mahana kiʻekiʻe loa ke hiki mai 850 a i 900℃. ʻO kēia mau mea a pau e hana i nā kiwikā pōpō kūpono no nā ʻano media āpau, kahi e lilo ai i ʻano kiwikā hoʻohiki nui loa.

Hiki ke hoʻokaʻawale ʻia nā kiwikā pōpō i nā kiwikā pōpō lana a me nā kiwikā pōpō trunnion ma muli o ke ʻano.

Hiki ke hoʻokaʻawale ʻia nā kiwikā pōpō i nā kiwikā pōpō komo luna a me nā kiwikā pōpō komo ʻaoʻao. Hiki ke hoʻokaʻawale ʻia nā kiwikā pōpō komo ʻaoʻao i nā kiwikā pōpō hoʻokahi ʻāpana, nā kiwikā pōpō ʻelua ʻāpana a me nā kiwikā pōpō ʻekolu ʻāpana e like me ke ʻano o ke kino kiwikā. He mea koʻikoʻi nā kino kiwikā o nā kiwikā pōpō hoʻokahi ʻāpana; ʻo nā kiwikā pōpō ʻelua ʻāpana he mau kino kiwikā nui a me nā kino kiwikā kōkua a ʻo nā kiwikā pōpō ʻekolu ʻāpana he kino kiwikā nui hoʻokahi a me ʻelua mau kino kiwikā kōkua.

Hiki ke hoʻokaʻawale ʻia nā kiwikā pōpō i nā kiwikā pōpō sila palupalu a me nā kiwikā pōpō sila paʻakikī e like me ka mea sila kiwikā. ʻO nā mea sila o nā kiwikā pōpō sila palupalu he mau mea polymer kiʻekiʻe e like me ka polytetrafluoroethylene (PTFE), polytetrafluoroethylene i hoʻoikaika ʻia a me ka nylon a me ka rubber. ʻO nā mea sila o nā kiwikā pōpō sila paʻakikī he mau metala.
