ʻO ka polymer fluorinated he semi-crystalline, semi-opaque a keʻokeʻo.Loaʻa iā ia ke kūpaʻa kemika koʻikoʻi ʻaʻole i hoʻopilikia ʻia e nā mea kemika āpau a he kiʻekiʻe hoʻi ka ʻenekene oxygen kiʻekiʻe (ʻo ia hoʻi, ʻaʻole ia he lapalapa).He haʻahaʻa haʻahaʻa loa ia o ka friction a paʻa i nā wela kiʻekiʻe.He palupalu, maʻalahi ka hoʻololi ʻana, hiki ke kolo a haʻahaʻa i ka ikaika me ka pale ʻana i ka radiation.He pipiʻi a ʻaʻole hiki ke hoʻoheheʻe ʻia (ʻoiai ma ke kumumanaʻo e hoʻoheheʻe ʻia ma 327C, ʻaneʻane pau ʻole ka viscosity heheʻe o nā māka maʻamau) a no laila ua hana ʻia e nā ʻano hana sintering pauda.
ʻO nā noi ʻoihana e pili ana i nā bearings, sila, O-rings, kiʻekiʻe wela uila insulation, non-stick coatings a me nā linings no nā moku etc, a me nā mea ʻē aʻe.
ʻO ke keʻokeʻo opaquePoe PTFEloaʻa i ka hoʻopau honua a me ka hoʻomanawanui maʻamau.ʻO ka Polypropylene (PP) he palaki ikaika a māmā me ka ʻili paʻakiki a maʻemaʻe i kūpono no ka hoʻohana ʻana i kahi kumu o ke kūkulu ʻana i nā maʻi bacteria.ʻO ka maʻamau, ʻoi aku ka ikaika, ʻoi aku ka paʻakikī, a ʻoi aku ke kūpaʻa ʻana i nā wela kiʻekiʻe ma mua o ka polyethylene, ʻoi aku ka maikaʻi o ka polypropylene i ke kūʻē i nā kemika a me nā mea hoʻoheheʻe.
ʻO ka plastik e pili ana i kahi hui o nā mea synthetic a semi-synthetic i hana ʻia e hoʻokō i nā waiwai kikoʻī.ʻO nā hiʻohiʻona kaulana loa o nā plastics ʻo ia kona kaumaha haʻahaʻa, machinability, corrosion resistance, a me nā waiwai insulating thermal a me nā uila.Hāʻawi pū kekahi mau māka plastik i ke aniani ʻikea like me ke aniani, ka haʻahaʻa haʻahaʻa a i ʻole nā lubricating surfaces, a me ke kūpaʻa kūʻokoʻa.Ma muli o ko lākou mau waiwai, hiki ke hoʻohana ʻia kekahi mau māka plastik i mea ʻokoʻa i ka metala, aniani, a me ka ceramic.ʻAʻole like me ka metala, hiki i ka plastic ke ʻike i ke kolo, ʻo ia ka deformation ma muli o ka loaʻa ʻana o ka ukana mau.
ʻO ka ikaika tensile, i hoʻohana ʻia e hōʻike i ka ikaika holoʻokoʻa o ka mea, ʻo ia ke koʻikoʻi kiʻekiʻe e hiki ke kū ma mua o ka haki ʻana.Hōʻike ka pale ʻana i ka corrosion i ka hiki o ka mea ke pale i ka pōʻino i hoʻokumu ʻia e ka lewa, ka makū, a i ʻole nā mea ʻē aʻe.Hōʻike ka pale ʻana i ka hiki ke pale i ka pōʻino o ka ʻili ma muli o ka hoʻopili ʻana me nā mea ʻē aʻe.Hōʻike ka ʻoʻoleʻa i ka hiki o ka mea ke komo i ka ikehu ma mua o ka haʻihaʻi ʻana, ʻoiai ka paʻakikī (i ana mau ʻia e like me ka paʻakikī indentation) e wehewehe ana i kona kūʻē ʻana i ka deformation mau loa.ʻO ke kū'ē i ka hopena ke ana o ka hiki o kahi mea ke komo i ka puiwa o ka ikehu ma mua o ka haki ʻana.
- Ke kū'ē nei ka PTFE i ka nui o nā kemika, kū mau i nā wela kiʻekiʻe, a he haʻahaʻa haʻahaʻa, nonstick surface- PTFE maʻamau kū i nā wela kiʻekiʻe ma mua o nā fluoropolymers ʻē aʻe, e like me FEP a me ETFE- Hoʻopau honua- He keʻokeʻo keʻokeʻo ke kala- Ke ahonui maʻamau
