O le fa'alava ma le fa'alava o le ie fiberglass e fuafua ai le fa'atinoga o ie vevela maualuga o le PTFE. O le maualuga maualuga e fa'ateleina ai le malosi ma'ale'ale ma le fa'alelei o luga ae fa'aitiitia ai le malosi o loimata (fa'aliliu U-curve), fetuutuuna'i, ma le fa'auluina o le ufiufi. O le mafiafia sili ona lelei e faapaleni ai le ati, tete'e o loimata, fetuutuuna'i, ma le mae'a. E fetaui ma le malosi o le punou; maualuga maualuga mo non-stick ma insulation.

Calendering - faʻapipiʻiina le ie faʻapipiʻi PTFE i le va o faʻata faʻavela i le 360-380 ° C - e matua suia ai le morphology o luga, 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. E taua mo le faʻasaʻoina o laina ma le faʻamalo 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). PTFE sili i le non-stick, ofuina tete'e, ma kemikolo tetee e oo atu i le 260°C. Ie silikoni e ofoina atu le sili atu le fetuutuunai, faʻapipiʻi eletise, ma le afi (e oʻo 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 maualuga-vevela ie ofo atu tulaga ese kemikolo tetee, tetee malosi acids, alkalis, solvents organic, ma kasa pala. O lenei tusiga o loʻo faʻamatalaina ana mea faʻasaʻo, tapulaʻa (metala alkali liusua, vailaʻau faʻafefete malosi), ma mea taua e pei o le vevela, faʻatonuga, ma faʻalavelave faʻainisinia.

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 faʻatumu 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 avaitaimi le lipine mo fa'ailoga o le ofuina po'o le fa'aleagaina. Suia pe a manaʻomia e faʻatumauina le faʻatinoga sili ona lelei.
