PEEK yog ib qho semi crystalline thermoplastic nrog cov khoom siv zoo heev thiab tshuaj lom neeg uas tau khaws cia rau qhov kub thiab txias. Cov txheej txheem ua haujlwm siv los pwm PEEK tuaj yeem cuam tshuam cov crystalline thiab yog li cov khoom siv kho tshuab. Nws cov Young's modulus yog 3.6 GPa thiab nws lub zog tensile yog 90 txog 100 MPa.[5] PEEK muaj qhov hloov pauv iav ntawm ib puag ncig 143 ° C (289 ° F) thiab yaj nyob ib puag ncig 343 ° C (662 ° F). Qee qib muaj qhov ua tau zoo ntawm qhov kub txog li 250 ° C (482 ° F).[3] Lub thermal conductivity nce ze li ntawm qhov kub thiab txias ntawm chav tsev kub thiab solidus kub.[6] Nws tiv taus thermal degradation, [7] nrog rau kev tawm tsam los ntawm ob qho tib si organic thiab aqueous ib puag ncig. Nws raug tawm tsam los ntawm halogens thiab muaj zog Bronzed thiab Lewis acids, nrog rau qee cov halogenated tebchaw thiab aliphatic hydrocarbons ntawm qhov kub thiab txias. Nws yog soluble nyob rau hauv concentrated sulfuric acid nyob rau hauv chav tsev kub, txawm hais tias dissolution yuav siv sij hawm ntev heev tshwj tsis yog tias lub polymer yog nyob rau hauv ib daim ntawv nrog ib tug siab-qhov chaw-rau-ntim piv, xws li ib tug zoo hmoov los yog nyias zaj duab xis. Nws muaj kev tiv thaiv siab rau biodegradation.
Kev tua tus kheej zoo heev, tsis tas yuav ntxiv cov nplaim hluav taws kub txog li 5VA

PEEK yog siv los tsim cov khoom siv rau kev thov, suav nrog cov kabmob, qhov chaw piston, twj tso kua mis, cov khoom ua haujlwm siab chromatography txhua, compressor phaj li qub, thiab hluav taws xob cable rwb thaiv tsev. Nws yog ib qho ntawm ob peb lub plastics sib xws nrog ultra-high nqus daim ntaub ntawv, uas ua rau nws haum rau aerospace, automotive, hluav taws xob, thiab tshuaj industries.[8] PEEK yog siv nyob rau hauv kev kho mob implants, piv txwv li, siv nrog ib tug high-resolution magnetic resonance imaging (MRI), rau tsim ib feem hloov pob txha taub hau nyob rau hauv daim ntawv thov neurosurgical.
PEEK yog siv rau hauv cov khoom siv txha caj qaum thiab cov pas nrig ntxiv.[9] Nws yog radiolucent, tab sis nws yog hydrophobic ua rau nws tsis tag nrho fuse nrog pob txha.[8] [10] PEEK cov ntsaws ruaj ruaj thiab manifolds feem ntau yog siv hauv cov dej siv. PEEK kuj ua tau zoo hauv cov ntawv thov kub (txog 500 ° F / 260 ° C).[11] Vim qhov no thiab nws cov thermal conductivity tsawg, nws kuj yog siv hauv FFF luam ntawv los thermally cais qhov kub kawg ntawm qhov txias kawg.
