Ki jan yo ka konsepsyon estrikti microporous nan Teflon rèspirant kasèt wo-tanperati balans pèmeyabilite lè a ak izolasyon ak pwopriyete ki pa baton?

Izolasyon (fòs dielectric) Konpoze nan dansite materyèl la. Entwodwi mikwoporèz ekivalan a melanje lè (avèk yon fòs dekonpozisyon ki ba ~ 3kV/mm) nan matris PTFE a, ak poros louvri yo bay chemen potansyèl pou dechaj pasyèl ak swiv paj ranp yo.

Airpermeabilityvs.non-stickproperty: Pwopriyete ki pa baton an soti nan enèji sifas ekstrèmman ba PTFE a (~18mN/m) ak sifas lis.

Atravè kalandriye chalè, tanperati wo-tanperati a kout tèm, oswa kouch ak yon fliyopolymère ultra-mens (egzanp, TeflonAF), sifas kontak ak objè a ap travay akeri yon sifas ki sanble ak yon fim adense.

Efè: Izolasyon domine pa kouch dens la, pèfòmans ki pa adhésè asire pa enèji sifas ki ekstrèmman ba a ak poros ultra-fin, ak pèmeyabilite lè a depann sou difizyon entèkouch la. ionandedgeconvection.Whenusedonheat-sealingmachines,thetapesurfacedoesnotsticktothemoltenfilm,whilemoistureandvolatilescanbeexpelledthroughtheedgesofthemicroporouslayer.
