Polytetrafluoroethylene (PTFE) waa walxo synthetic ah oo si lama filaan ah loo allifay dabayaaqadii 1930-meeyadii iyadoo farmashiye uu ku dadaalayay inuu sameeyo nooc cusub oo qaboojiye ku salaysan perfluorethylene.Halkii uu ka gaadhi lahaa chlorofluorocarbon, saynisyahanku waxa uu la yaabay in uu ogaaday in perfluorethylene ee loo isticmaalay hawsha ay ka fal-celisay maadada birta ah ee weelkeeda iyo polymerized markii cadaadis la saaray.In ka yar toban sano ka dib, alaabtan cusub ayaa loo qaybiyay si ganacsi ah waxaana ugu dambeyntii lagu sii daayay magaca polymer®.Waxay noqon doontaa 20 sano oo kale ka hor inta aysan walaxdani ku dhicin digsiga shiilan oo loo yaqaan dahaarka ugu horreeya ee aan dhegta lahayn ee cunto kariska, si kastaba ha ahaatee.Dhab ahaantii, walxahan waxaa loo adeegsaday ujeedooyin kale oo kala duwan markii hore.
