O lenei tusiga e faʻatusatusa le saʻo o metotia suʻega tikeri e tolu mo suʻega faʻapipiʻi silikoni. Solvent extraction (gel content) e fuaina vaega vaega ole feso'ota'iga e ala i Soxhlet extraction - fa'asilisili ona o vaega lavelave fa'aletino ua fa'aseseina e pei o feso'ota'iga, sa'o ± 2-5%, sili ona sa'o vaila'au. E fuaina e le DSC le vevela o le tali (α=1-ΔHresidual/ΔHtotal) - faʻalagolago i le maualalo-i-medium liua ae ova le faʻatusatusa i le maualuga o le liua ona o faʻasalalauga faʻatapulaʻa vaega o totoe, toe mafai <± 2%.

PTFE maualuga-vevela ie e lautele faaaogaina i le alamanuia vailaau mo talosaga autu e fitu: flange gaskets ma paipa linings (tetee malosi acids/alkalis), reactor ma tane linings (puipuia uamea pala, faamama mama), taga faamama mo kesi fue corrosive (e oo atu i le 260°C), anti-corrosion faalautele sooga mo ducts fa'amavae, fa'alava ie puipui mo ducts fa'amavae, fa'alava fa'apipi'i mo ducts fa'alava, fa'amavaega fa'alava fa'ameamea ma afifi fa'amalama eletise/vevela. FDA ma UL togi avanoa.

Fa'auma fa'auma sui fa'aoga i le ie fiberglass a'o le'i fa'apipi'iina le PTFE e taua tele mo le fa'atinoina o ie vevela maualuga o le PTFE. Organosilane so'o fa'apipi'i fa'atūina alalaupapa mole i le va o alava tioata inorganic ma organic PTFE, fa'ateleina le malosi pa'u mai <2 N/cm i le 4-8+ N/cm. O togafitiga talafeagai e faʻaleleia ai foi le faʻafefe o le vevela (260 ° C +), faʻaogaina o le dielectric, ma le faʻamaʻiina o vailaʻau. O ie e le togafitia e tau atu i le delamination, fa'afefeteina, ma le ola puupuu.
