PTFE maualuga-vevela ie tausia lelei insulation eletise mai -180 °C i 260 °C: voluma resistivity>10¹³ Ω·cm i 200 °C, dielectric tumau mautu i 2.0-2.1. I luga aʻe o le 260 ° C, faʻamaluluina le PTFE, faʻaleagaina i luga aʻe o le 327 ° C, faʻaumatia faʻamaufaʻailoga tumau. I lalo ifo o le 0°C, e fa'aleleia atili le fa'a'ese'esega ae o le fa'alavalava e malepe. Tumau i totonu ole 260°C mo le fa'atinoga fa'atuatuaina.

PTFE maualuga-vevela ie (PTFE-coated fiberglass) e lelei mo fusi conveyor meaʻai ona o lona 260 ° C vevela tetee, -70 ° C malulu fetuutuunai, luga e le o laau, ma le tausisia FDA. Fa'aoga autu: ogaumu faifalaoa (masi, falaoa, pizza), fe'avea'i mea'ai falai, laina fa'amalie lole, alavai fa'aaisa, fa'amaufa'ailoga vevela, ma le afifiina. Faʻaitiitia taimi faʻaumatia ma faʻamamā.

Calendering - faʻapipiʻi le ie faʻapipiʻi PTFE i le va o faʻata faʻavela i le 360-380 ° C - faʻafefeteina le faʻaogaina o le eleele, faʻasaʻo meatotino, le mafai, ma le faʻaaogaina o masini. E faʻaitiitia ai le talatala mai le Ra 0.5-1.0 μm i le <0.05 μm, faʻamaufaʻailoga pine, faʻaleleia le faʻaogaina o le ofuina, ae faʻaitiitia le malosi o loimata ma le fetuutuunai. Mana'omia mo le fa'asa'oina o laina laina ma le fa'aeseese eletise.

PTFE maualuga-vevela ie ma silicone ie e faʻaaoga uma le ie fiberglass e fai ma faʻavae ae ese i mea faʻapipiʻi (PTFE resin vs silicone rubber). O le PTFE e sili atu i le non-stick, of wear resistance, ma le vailaʻau e oʻo atu i le 260°C. Ie Silicone e ofoina atu le sili atu ona fetuutuunai, fa'amalo eletise, ma le afi (e o'o atu i le 230°C). Filifili e fa'atatau i lau fa'amuamua.

PTFE maualuga-vevela ie (PTFE membrane material) o se filifiliga sili ona lelei mo le fausaga faʻapipiʻi. Fa'amanuiaga autu: 30+ tausaga le olaga i fafo, fa'amamāina e le tagata lava ia (vai timu e fufulu palapala), moli vaivai (6-13%), Vasega A afi fua, ma le malosi pei o le sila i lalo ole 1.5 kg/m². Fa'aoga i malae ta'alo, malae va'alele, ma fale fa'ailoga i le lalolagi atoa.

PTFE impregnation e le gata i ie fiberglass. O lenei tusiga o loʻo faʻaalia ai isi mea e 7 - aramid, carbon fiber, PBI, porous metal, graphite, asbestos (faʻaumatia), ma faʻapipiʻi sima - faʻatasi ai ma a latou faʻagasologa o foliga, lelei, tapulaʻa, ma faʻaoga autu.

O lenei tusiga o loʻo faʻamatalaina pe aisea e avea ai le ie fiberglass e sili ona lelei mo le PTFE ie vevela maualuga. E aofia ai le fa'aogaina o vaila'au e ala i so'o fa'apipi'i silane ma mea taua fa'aletino e pei o le mautu o le vevela, tulaga mautu, ma le tete'e o le a'a - fa'amautinoa le fa'atino umi i si'osi'omaga faigata.
