I-Calender – ukucindezela indwangu eboshwe nge-PTFE phakathi kwamarola esibuko ashisisayo ku-360-380°C – kushintsha ngokuphawulekayo ukumila kwendawo, ukukhulula izakhiwo, ukungaboli, nokusebenza komshini. Yehlisa ukuhwaqaza ukusuka ku-Ra 0.5-1.0 μm kuya ku-<0.05 μm, ivala amaphinifa, ithuthukise ukumelana nokugqoka, kodwa inciphisa amandla okudabula nokuguquguquka. Ibalulekile ekukhululeni ama-liner kanye nokufakwa kukagesi.

Iphethini ye-Fiberglass weave - plain, twill, noma satin - ithinta kakhulu izici zendwangu yezinga lokushisa eliphezulu le-PTFE. I-Satin weave inikeza amandla aphezulu okudabula (2-3x plain) kanye nokuguquguquka, ilungele ukugoba okuguquguqukayo. I-Plain weave ihlinzeka ngokuzinza kwe-dimensional okungcono kakhulu kanye nokunamathela kwekhasi, okulungele ukusetshenziswa okumile. I-Twill ibhalansisa zonke izakhiwo ukuze zisetshenziswe ngokujwayelekile.

Ukufana kokunamathela kwendwangu yokushisa ephezulu ye-PTFE kunqunywa izici ezine: ukwakheka kokumboza (usayizi wezinhlayiyana 0.15-0.35 μm, i-viscosity, okuqukethwe okuqinile), inqubo yokugqoka kanye ne-sintering (i-blade enamathela ekhethwayo ukuze ifane), ikhwalithi ye-substrate (iphethini yokuluka, ukwelashwa kwangaphambili), nendawo yokukhiqiza (20-25% R <60%). I-Dip + blade inqubo ehlanganisiwe ilinganisa ukungena nokushelela kwendawo.

Indwangu ye-PTFE enezinga lokushisa eliphezulu inikeza ukumelana kwamakhemikhali okukhethekile, imelana nama-acids aqinile, ama-alkali, izinyibilikisi eziphilayo, namagesi abolayo. Lesi sihloko sichaza ngezinto ezimelana nayo, imikhawulo (izinsimbi ze-alkali ezincibilikisiwe, ama-ejenti anamandla e-fluorinating), nezici ezibalulekile ezifana nezinga lokushisa, ukugxilisa ingqondo, nokucindezeleka komshini.

Njengomkhiqizi ochwepheshe wezindwangu ze-PTFE ezisezingeni eliphezulu, i-Jiangsu Aokai New Materials ikunikeza imininingwane yobungcweti. Inhloso eyinhloko yokwelashwa kwendawo ye-fiberglass ukwakha ibhuloho lamangqamuzana phakathi kwe-inorganic fiberglass ne-organic PTFE, ukuze kuxazululwe ngokuyisisekelo inc yabo yemvelo.
