ʻO ka Polytetrafluoroethylene (PTFE) he polymer o ka tetrafluoroethylene (TFE), he mea koʻikoʻi ka fluorine organik me nā waiwai dielectric maikaʻi loa a me ka coefficient friction haʻahaʻa.Hoʻohana maʻamau e like me nā plastics engineering, hiki ke hana ʻia i polytetrafluoroethylene tube, rod, tape, plate, film, etc., i ka ʻoihana, ke ola o kēlā me kēia lā a me nā māla ʻē aʻe i hoʻohana nui ʻia, loaʻa ka inoa ʻo "plastic King".
I kēia mau makahiki i hala iho nei, ua ulu wikiwiki ka ʻai honua o PTFE, a hiki i kahi 70% o ka nui o ka hoʻohana ʻana i ka resin fluorine.Mai ka makahiki 2010, ua hui pū ʻia ʻo Kina me ka hoʻololi ʻana o ka mana hana PTFE i kiʻekiʻe a kūikawā i nā ʻāina i kūkulu ʻia, a ua neʻe aku kekahi o kāna mana hana PTFE haʻahaʻa i Kina.
I kēia manawa, ua lilo ʻo Kina i mea hana nui o ka honua o PTFE.Ua manaʻo ʻia ʻo Kina ka mana kūpono o TEflon ma 2020 he 149,600 tons, e ʻike ana he 97,200 tons o ka hana ʻana, e helu ana ma kahi o 60% o ka mākeke honua.
