PTFE yog siv los ua ib lub npe lag luam rau ob peb lwm cov polymers uas zoo sib xws, xws li ethylene propylene (FEP) thiab perfluoroalkoxy resin (PFA) Cov khoom ntawm cov polymers no zoo ib yam li cov ptfe.
FEPFEP yog softer dua polymer thiab yog pob tshab thiab tiv taus tshav ntuj.Nws yog formable ntau tshaj li polymer.Nws muaj qhov tsis tshua muaj coefficient ntawm kev sib txhuam thiab siab ua haujlwm kub.Nws tuaj yeem siv rau vuam, kub-sealing, thiab thermoforming.Nws yog siv rau hauv kev tsim thiab tsim cov thermoplastics uas tsis tshua muaj kev sib txhuam.FEP nonstick coatings yog nrov siv rau txheej ntim cov khoom siv hauv kev lag luam ci.FEP muaj nyob rau hauv ob qho tib si dej-raws li kua daim ntawv thiab hmoov daim ntawv.
mus saib cov khoom ntawm FEP.
PFAPFA yog nonreactive nyob rau hauv cov xwm thiab muaj ib tug tsawg coefficient ntawm kev sib txhuam.PFA kuj tseem siv rau txheej cov khoom ci ci.Txawm li cas los xij, cov yam ntxwv ua haujlwm ntawm PFA zoo dua li cov FEP vim tias PFA tuaj yeem tiv taus qhov kub thiab txias rau lub sijhawm ntev.Tsis tas li ntawd, nws muaj zog ntau dua li FEP thiab polymer.PFA muaj nyob rau hauv hmoov thiab kua daim ntawv.
mus saib cov khoom ntawm PFA.
Tefzel lossis ETFEETFE yog copolymer ntawm ethylene thiab tetrafluoroethylene.Nws lub npe lag luam yog Tefzel.Cov qauv molecular ntawm ETFE yog txawv me ntsis ntawm cov polymer.Nyob rau hauv polymer, tag nrho cov hydrogen atoms yog hloov los ntawm fluorine thaum nyob rau hauv ETFE, ib tug me me ntawm hydrogen molecules yog hloov.
