PTFE, lossis polytetrafluoroethylene, feem ntau yog hu ua "huab cua ntawm plastics", yog cov molecular polymer ua los ntawm tetrafluoroethylene raws li monomer. Nws yog dawb powdery, tsw ntxhiab thiab tsis muaj tshuaj lom.
PTFE muaj ntau yam khoom tau zoo heev. Hais txog qhov kub tsis kam, nws tuaj yeem siv rau hauv qhov kub thiab txias ntawm 260 qib kev ntsuas kub ntawm 2600 lub sij hawm tsis kam ntawm ntau dua 300 degree. Nws cov kev ua tau zoo tseem ruaj khov nyob rau hauv ib puag ncig kub thiab nws tuaj yeem tswj tau yooj yim txawm tias kub tsawg. Nyob rau hauv cov nqe lus ntawm cov tshuaj tsis kam, nws muaj cov muaj zog heev rau cov tshuaj xws li acids, alkalis, thiab cov kuab tshuaj, thiab muaj zog corrosion tsis kam. Nws kev sib txhuam coefficient yog qhov tsawg heev, tsawg li 0. {}}} Nyob rau tib lub sijhawm, PTFE tseem muaj rwb thaiv hluav taws xob zoo thiab cov khoom siv hluav taws xob tsawg kawg rau cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob; Raws li zoo li biocompatibility zoo heev, nws tau dhau FDA ntawv pov thawj thiab tuaj yeem siv hauv kev cuam tshuam kev kho mob.
PTFE muaj ntau cov kev siv. Hauv kev lag luam tshuaj, nws tuaj yeem siv los ua cov ntaub ntawv sealing rau cov kav dej rau cov kav dej rau cov kav dej rau cov kav dej thiab cov li qub, thiab cov yeeb nkab fittings; Hauv kev tiv thaiv kev tiv thaiv corrosion, nws yog siv los ua cov duab tso duab thiab cov yeeb yaj kiab rau cov khoom siv hluav taws xob thiab hluav taws xob siv hluav taws xob, feem ntau yog siv hluav taws xob cov ntaub ntawv thiab cable. Hauv kev sib txuas lus 5G kev sib txuas lus, nws ntau zaus tooj liab-clad laminates, xov tooj cua tau muab cov xov tooj thiab lwm yam kuj ua lub luag haujlwm tseem ceeb. Ib qho ntxiv, nws tseem siv nyob rau hauv cov tsheb ntawm tsheb, kev kho mob, kev kho mob, xws li hloov pauv ntawm kev kho mob thiab lwm yam.
Txawm li cas los xij, PTFE tseem muaj qee qhov kev txwv, xws li qhov nyuaj ntawm kev ua, qhov tsis muaj peev xwm rau cov txheej txheem yaj, thiab qhov yuav tsum tau tso siab rau cov txheej txheem tshwj xeeb; Nyob rau hauv cov nqe lus ntawm cov neeg kho tshuab, txias txaus, qis ntws tsis kam, tsawg cov tshuab muaj zog thiab lwm yam teeb meem yuav tsum tau txiav txim siab thiab ua tiav thaum siv thiab ua tiav.
