Ikhalenda – ukucinezela ilaphu eligqunywe nge-PTFE phakathi kweerola zesipili ezishushu kwi-360-380°C – kuguqula ngokumangalisayo ukumila komphezulu, iipropathi zokukhulula, ukungagungqi, kunye nokusebenza koomatshini. Iyanciphisa uburhabaxa ukusuka ku-Ra 0.5-1.0 μm ukuya ku-<0.05 μm, itywina i-pinholes, iphucula ukuchasana nokugqoka, kodwa iyancipha amandla okukrazula kunye nokuguquguquka. Kubalulekile ukukhulula iilitha kunye nokufakelwa kombane.

Ilaphu le-PTFE lobushushu obuphezulu (i-PTFE inwebu yempahla) lukhetho lweprimiyamu yolwakhiwo oluqinileyo. Izinto eziluncedo ezingundoqo: iminyaka engama-30+ yobomi bangaphandle, indawo yokuzicoca (amanzi emvula ahlamba ubumdaka), ukuhanjiswa kokukhanya okuthambileyo (6-13%), ukukala komlilo kuDidi A, kunye namandla afana nentsimbi angaphantsi kwe-1.5 kg/m². Isetyenziswa kumabala emidlalo, kwizikhululo zeenqwelo moya, kunye nezakhiwo ezinomfanekiso kwihlabathi liphela.
