ʻO Polytetrafluoroethylene (PTFE) ka mea i hoʻohana nui ʻia i ka fluoropolymer, ʻo ia ka mea kūʻokoʻa i ka corrosion kemika, loaʻa nā waiwai dielectric maikaʻi loa a me kahi ākea o nā ʻano wela hana, ʻike ʻia ʻo "ke aliʻi o nā plastics".

ʻAʻole hoʻoheheʻe ʻia ka PTFE a ʻaʻole pehu i kekahi o nā wai i ʻike ʻia, no lailaPTFEʻAʻole loli nā ʻāpana i ka nui i kekahi ʻano corrosive, no ka lōʻihi o ka hoʻohana ʻana.Hana ʻo PTFE i nā ipu hao lahilahi i hoʻohana nui ʻia i loko o nā laboratories a me nā hale hana e hoʻohana ai i nā wai corrosive, a hoʻohana nui ʻia i nā sila, nā paipu paipu, nā pamu, nā kiwi, etc.

ʻO nā waiwai dielectric maikaʻi loa o PTFE, kahi kūʻokoʻa kūʻokoʻa i ka mahana a me ke alapine, a me kona kūpaʻa wela kiʻekiʻe, e hoʻolilo iā ia i insulator uila hiki ʻole ke hoʻololi ʻia, ʻoi aku hoʻi i nā alapine kiʻekiʻe a me nā mahana a me nā wahi humid.
I kēia lā, nui nā ʻano o nā mea PTFE i hana koʻikoʻi i ke kula o ka uila a me ka uila uila.Hoʻohana ʻia ka PTFE aniani lacquer a me ka lole aniani e hana i nā mea insulation kiʻekiʻe a me nā kiʻekiʻe-frequency, hiki ke hoʻohana ʻia i nā kamaʻilio ukali a me nā kamepiula.Hoʻohana ʻia ke kiʻi ʻoniʻoni PTFE e hana i nā capacitors, ma ke ʻano he insulation layer ma waena o nā mea kani, gaskets, cables, etc.PTFEHoʻohana ʻia nā paipu ʻeleʻele o nā anawaena like ʻole no nā lima uea alakaʻi, nā paipu hiki ke wela a me ka paipu spiral, ka paipu pailaka insulated no nā mea hana, etc.
