Ukomisa linyathelo elibalulekileyo kwi-PTFE yokuvelisa ilaphu lobushushu obuphezulu. Iziphene eziqhelekileyo zibandakanya: ukuqhekeka (ukomisa ngokukhawuleza, ukukhupha isikhumba), ukufuduka (amasuntswana ahambela phezulu, ibhondi yangaphakathi ebuthathaka), imibhobho / amadyungudyungu (umoya obanjwe okanye umphunga), amabala amhlophe kunye ne-chalking (ukufuduka kwe-surfactant okanye ukudityaniswa okungaphelelanga), i-yellowing / coking (ukushisa ngokugqithiseleyo kwezongezelelo), i-delamination (i-sherinkage ye-peelleven), i-dealmine (i-sherinkage ye-peelle, i-deeling, i-dealer, i-dealer, i-dealer, i-dealing, i-dealer, ukushwabana), umphezulu womile kodwa ngaphakathi umanzi (ukulusu lubamba ukufuma), kunye nemiphetho engqindilili (isiphumo sekofu). Izisombululo zibandakanya iiprofayili zokomisa ezilawulwayo, ukungena komoya okufanelekileyo, kunye nokunyangwa kwangaphambili kwe-substrate.

Ilaphu le-PTFE elinobushushu obuphezulu lisetyenziswa kakhulu kushishino lweekhemikhali kwizicelo ezingundoqo ezisixhenxe: iigaskets zeflange kunye nelayini yombhobho (ixhathise i-acids eyomeleleyo/alkali), i-reactor kunye ne-tank linings (ithintela ukubola kwesinyithi, ukucoca lula), iingxowa zokucoca igesi enomhlwa (ukuya kuthi ga kwi-260°C), i-anti-corrosion expansion, i-anti-corrosion extensions ukubumba okuhlanganisiweyo, kunye nokusonga kombane/kwe-thermal. I-FDA kunye ne-UL amabakala akhoyo.

Iiarhente zokugqiba umphezulu ezifakwe kwilaphu le-fiberglass phambi kokutyabeka kwe-PTFE zibalulekile kwi-PTFE yokugqibela yokusebenza kwelaphu lobushushu obuphezulu. I-Organosilane coupling agents zenza iibhulorho ze-molecular phakathi kwe-fiber yeglasi ye-inorganic kunye ne-organic PTFE, ukunyusa amandla e-peel ukusuka ku-<2 N / cm ukuya kwi-4-8+ N / cm. Unyango olufanelekileyo lukwaphakamisa ukuxhathisa ukushisa (260 ° C +), ukusebenza kwe-dielectric, kunye nokuchasana kweekhemikhali. Ilaphu elingaphathwanga likhokelela kwi-delamination, ukugqabhuka, kunye nobomi obufutshane benkonzo.
