PTFE maualuga-vevela ie - PTFE-coated fiberglass - ua avea ma alu-i fofo mo nei siosiomaga filtration faigata. O lona tu'ufa'atasiga o le 260°C fa'afefeteina o le vevela, vaila'au inertness, non-stick surface, ma le fa'amautu tulaga e matua taua tele mo le aoina o le pefu ato, ie faamama vai, ma fa'amama ea maualuga.
Aokai PTFE sapalai PTFE ie mo filtration talosaga i le lalolagi atoa. O lenei tusiga o loʻo aofia ai vaega tetele e lima: faʻamalo le pefu kasa vevela maualuga, faʻamama vai faʻamaʻi, meaʻai / vailaʻau faʻamaʻi faʻamaʻi, faʻamamaina o le ea mama, ma le faʻamamaina faʻapitoa.
