PTFE i luga o togafitiga mo le pipi'i fa'apipi'i e fa'aaogaina auala autu e lua: fa'afefeteina maualuga (maualuga le tau tetee, 9.5 MPa malosi ma so'o fa'atasi, ae fa'asaoina kasa oona) ma le sodium-naphthalene etching (5 MPa fa'apipi'i vave, vaapiapi 24-48 itula fa'amalama, otaota matautia). Filifili e fa'atatau i le fa'atonutonuina o le si'osi'omaga ma le fa'atinoga o taimi umi vs.

Fa'ata'ita'iga le lelei o le emulsion PTFE e aofia ai fa'ailoga autu e ono: mea mautu (60±2% i le T/FSI 067-2021), pH (9.0-11.0), fa'asoaina o vaega (laser diffraction/DLS), viscosity (12-30 mPa·s i le 25°C), mautu (centrifugal, thermal, freeze.thaw). O lenei ta'iala o lo'o aofia ai metotia fa'ata'ita'iga masani mo parakalafa ta'itasi.
