PTFE shine polymer thermoplastic, wanda yake shi ne fari mai ƙarfi a cikin zafin jiki, tare da nauyin kusan 2200 kg/m3.Yana kiyaye babban ƙarfi, tauri da lubrication kai a ƙananan yanayin zafi zuwa 5 K (-268.15 ° C; -450.67 °F), da kuma sassauci mai kyau a yanayin zafi sama da 194 K (-79 °C; -110 °F).PTFE yana samun kaddarorin sa daga jimillar tasirin carbon-fluorine bond, kamar yadda duk fluorocarbons ke yi.Abubuwan sinadarai guda ɗaya da aka sani suna shafar waɗannan haɗin gwiwar carbon-fluorine sune karafa masu amsawa sosai kamar ƙarfe na alkali, kuma a yanayin zafi mai girma haka kuma irin su aluminum da magnesium, da abubuwan da ke haifar da fluorine kamar xenon difluoride da cobalt (III) fluoride.
Yawan juzu'i na gogayya na robobi yawanci ana auna shi da gogaggen karfe.PTFE's coefficient na gogayya shine 0.05 zuwa 0.10, wanda shine mafi ƙasƙanci na uku na kowane ingantaccen abu.Juriya na PTFE ga sojojin van der Waals yana nufin cewa ita ce kawai sanannen saman da gecko ba zai iya tsayawa ba. A gaskiya ma, PTFE za a iya amfani da shi don hana kwari hawan saman da aka fentin da kayan.PTFE yana da santsi sosai cewa kwari ba za su iya kamawa ba kuma suna iya faɗuwa.
Saboda rashin kuzarin sinadarai, PTFE ba za a iya haɗe-haɗe kamar elastomer ba.Saboda haka, ba shi da "ƙwaƙwalwar ajiya" kuma yana da wuyar shiga.Saboda mafi girman sinadarai da kaddarorin thermal, PTFE galibi ana amfani dashi azaman kayan gasket a cikin masana'antu waɗanda ke buƙatar juriya ga sinadarai masu ƙarfi kamar magunguna ko sarrafa sinadarai.Duk da haka, saboda da'awar rarrafe, aikin dogon lokaci na irin waɗannan hatimin ya fi muni fiye da na elastomers waɗanda ke nuna sifili, ko kusa-sifi, matakan rarrafe.
Gudanar da PTFE na iya zama mai wahala da tsada, saboda yawan zafin jiki mai narkewa, 327 °C (621 °F), yana sama da zafin bazuwar farko, 200 °C (392 °F).Ko da lokacin narke, PTFE ba ya gudana, amma a maimakon haka yana nuna hali a matsayin gel saboda rashin lokaci na crystalline da babban narke danko.
Wasu sassa na PTFE ana yin su ta hanyar gyare-gyaren sanyi, wani nau'i na gyare-gyaren matsawa.Anan, ana tilasta PTFE foda mai kyau a cikin wani tsari a ƙarƙashin babban matsin lamba.Bayan lokacin daidaitawa, yana dawwama daga mintuna zuwa kwanaki, ana yin zafi a zazzabi na 360 zuwa 380 ma'aunin Celsius, yana barin ɓangarorin lafiya su haɗa cikin taro ɗaya.
