Ilaphu elinobushushu obuphezulu be-PTFE lenziwa ngokugquma i-PTFE kwilaphu le-fiberglass eyomelele kakhulu, linika amandla anqabileyo, ukuxhathisa ubushushu, iipropati ezinganamatheli, ukumelana neekhemikhali, kunye nokukhuhlana okuphantsi. Usetyenziso oluphambili lubandakanya: ukuhanjiswa kwemizi-mveliso (ukupakishwa kokunciphisa ubushushu, ukubhaka ukutya, izomisi zelaphu, ukomisa iphepha/ifilimu); ilaphu lokubumba elidityanisiweyo kunye neelinen ezishushu zokucofa umqamelo; ukuwelda amakhethini akhuselayo kunye neebhatyi ze-thermal insulation; i-motor yombane kunye ne-transformer insulation; ukwakha iibheringi zokutyibilika kunye nezixhaso zemibhobho; ukuhluzwa kweekhemikhali kunye nokutywinwa kwevalve kwindawo ezonakalisayo. Amandla aphezulu okuqina aqinisekisa ukuqina phantsi koxinzelelo, ukukrazula, ukuguquguquka okuphindaphindiweyo, kunye noxinzelelo oluphezulu lobushushu bomatshini kuzo zonke ezi zicelo zahlukeneyo zomsebenzi onzima.

Ngexesha le-sintering, amasuntswana e-PTFE kwilaphu ye-fiberglass anyibilika ngaphezulu kwe-327 ° C, etshabalalisa i-lamellae esongiweyo yoqobo kunye nemida yamasuntswana ukwenza i-amorphous melt. Ekupholiseni, i-PTFE iphinda ihlaziye kwi-spherulites eyenziwe nge-radially oriented lamellae, kunye ne-crystallinity esukela kwi-50-70%. Izinga lokupholisa limisela ukugqibelela kwekristale: ukupholisa okucothayo kuvelisa i-crystallinity ephezulu, ii-spherulites ezinkulu, ubunzima obukhulu; ukucima ngokukhawuleza kunika i-spherulites ecocekileyo kunye nokuguquguquka okuphuculweyo.
