Ko te ETFE (ethylene tetrafluoroethylene) he fluoropolymer e whakamahia whānuitia ana hei whakamarumaru mō te waea litz kua whakapūtāhia nā te mea he pai rawa atu ōna āhuatanga wera, matū, me te hiko. Ina aromatawaihia ana mēnā he mārō, he ngohengohe rānei te ETFE i tēnei tono, me whai whakaaro ki tōna whanonga ā-pūkaha.
He rauemi pakari, ātete hoki ki te pakū te ETFE, engari ko tōna ngāwari ka whakawhirinaki ki ngā āhuatanga tukatuka. Hei paninga whakaputa mō te waea litz, he āhua pakari te ETFE—he pakari hei pupuri i te hanganga tika, engari he ngāwari hei tuku i te piko me te takahuri me te kore e pakaru. He rerekē ki ngā rauemi ngohengohe pēnei i te PVC, i te silicone rānei, kāore te ETFE e ahua "ngawari" ki te pā engari he pai te whakakotahitanga o te pakari me te ngāwari.
Ka pāngia te pakeke o te whakamarumaru ETFE e ngā āhuatanga pēnei i te matotoru me ngā tawhā whakaputa. Ka mau tonu te ngāwari o ngā paninga ETFE angiangi, e pai ai mō ngā tono waea litz auau teitei e tino hira ana te ngaronga tohu. Heoi, ko ngā whakaputa matotoru ake ka ahua uaua ake, ka whakarato i te tiaki miihini pai ake.
Ki te whakatauritea ki te PTFE (polytetrafluoroethylene), he ngawari ake, he ngāwari ake hoki te ETFE, ā, he pai ake mō ngā tono hihiri. Ko tōna pakeketanga Shore D kei waenganui i te 50 me te 60, e tohu ana i te pakari taurite.
Hei whakamutunga, ko te ETFE e whakamahia ana i roto i te waea litz kua whakapūtātia ehara i te mea tino mārō, ehara hoki i te mea tino ngawari. Ka taurite te pakari me te ngāwari, kia pono ai te whakamarumaru me te kore e whakararu i te mahi i roto i ngā taiao hiko uaua.
Haunga te ETFE, ka taea hoki e Ruiyuan te whakarato i ētahi atu kōwhiringa o ngā ārai wera mō te waea litz, pērā i te PFA, te PTFE, te FEP, me ētahi atu. He mea hanga ki ngā ara iahiko parahi, te aho parahi whakakikoruatia ki te tine, te aho waea parahi whakakikoruatia ki te hiriwa, me ētahi atu.
