Polytetrafluoroethylene (PTFE) imamveka ngati yasayansi yambiri koma imadziwika bwino ndi dzina lake:polima.Aliyense ayenera kukhala ndi miphika yopanda ndodo ndi mapoto omwe amakutidwa ndi PTFE.Kuphatikiza kwa mankhwala ndi zinthu zakuthupi za PTFE ndi zotsatira za mawonekedwe ake enieni a fluorocarbon.Kapangidwe kachilendo kameneka kamatsogolera kuzinthu zomwe zimakhala ndi inertness pafupifupi chilengedwe chonse;insolubility wathunthu mu zosungunulira zodziwika pansi 300 ° C;kwambiri matenthedwe bata;ndi mphamvu zamagetsi zopanda mphamvu, kuphatikizapo kuchepa kwa dielectric, kutsika kwa dielectric nthawi zonse ndi mphamvu ya dielectric yapamwamba.Komanso, PTFE si embrittle pa kwambiri kapena pa kutentha otsika kwambiri.
1. Kutentha kwapamwamba: Kukhoza kugwira ntchito mokhazikika pakati pa 200 ° C ndi +260 ° C.2.Kukana kutentha kochepa.Ili ndi kulimba kwamakina kwambiri -180°C.3.Katundu wothira mafuta ambiri.4.Katundu wabwino kwambiri wotsekereza.5.Katundu wabwino wosamata.6.Zosavulaza7.Anti-corrosion.8.Kutalika kwa nthawi yayitali
