Polytetrafluoroethylene (PTFE) waa polymer culus oo miisaankiisu sarreeyo, mid ka mid ah maaddooyinka balaastigga ah ee ugu badan ee loo yaqaan oo faa'iido u leh badeecooyin badan oo kala duwan oo loogu talagalay codsiyada laga reebo alaabta kale.
Polytetrafluoroethylene (PTFE ee gaaban) waa caag jilicsan oo hooseeya kaas oo muddo dheer loo isticmaali jiray codsiyada daboolka ah ee walxaha kala duwan oo ay ku jiraan gaasaska, dareeraha, iyo kiimikooyinka.
PTFE O-ring Heerkulka Heerkulka
Inkasta oo PTFE ay leedahay sifooyin farsamo oo hooseeya marka loo eego balaastikada kale, caabbinta kiimikada ee walxaha ee tandem iyada oo awood u leh inay u adkeyso heerkul ballaaran (-100oF ilaa + 400oF) waxay u ogolaataa PTFE o-rings si ay u bixiso iska caabin wax ku ool ah cimilada iyo sidoo kale korantada iyo kulaylka. dahaarka.
Sababtoo ah PTFE waa walxo cufan oo caynkaas ah, lama "dhalaali karo" - waa in la cadaadiyo oo la miisaamaa si loo sameeyo qaabab waxtar leh (sida o-rings).
