Lub zog tensile, flexural zog, flexural modulus, feem zog thiab elongation ntawm PEEK yog heev nyob rau hauv chav tsev kub. Cov kev ntseeg no yog siab tshaj cov khoom uas tsis zoo, tab sis muaj qis loj thaum kub kub tshaj qhov iav hloov kub. Tom qab siv cov iav fiber ntau thiab cov fibre fiber ntau, lub zog tensile, feem zog, ua kom tsawg zog thiab modulus nce zoo heev, thiab cov elongation decreases heev. Tsis tas li ntawd, PEEK kuj muaj qhov zoo tsis txaus siab, thiab kev qaug zog ntawm kev kuaj cov hmoov txhaws xeeb kuj zoo nkaus li, thiab nws tuaj yeem tiv taus cov teebmeem rov qab.
PEEK muaj cov tshuaj tiv thaiv zoo heev, thiab nws cov Tg yog 143 ° C, Tm yog 334 ° C, kub kub qhov kub li cas yog 135 ~ 160 ° C thaum tsis kho, thiab qhov siab siv qhov kub siab mus txog 240 ° C. Tom qab siv zog 20 % iav fiber ntau, kub kub qhov muag kub txog 286 ° C, thiab lub tshav kub distortion kub tom qab siv zog nrog 30% iav fiber ntau los yog carbon fiber ntau tshaj 300 ° C.
Tsis tas li, PEEK kuj muaj cov thermal oxygen stability siab. Txoj kev nkhaus thermogravimetric qhia tau hais tias lub thermal qhov hnyav ntawm 400 ° C yog 0, 2.5% ntawm 500 ° C, thiab 59% ntawm 600 ° C. PEEK muaj cov khoom hluav taws xob zoo thiab muaj zog loj heev. Lub dielectric tas li yog 3.2-3.3 ntawm lub zaus (50-1010 Hz) thiab kub (0-150 ° C), thiab lub zog dielectric yog 16-21 kv / hli. Nws tsis cuam tshuam los ntawm cov av noo thiab yuav siv tau raws li cov khoom siv Class Class rwb thaiv tsev. PEEK yuav tiv taus rau txhua yam tshuaj lom neeg tshwj tsis yog cov concentrated sulfuric acid, thiab tswj cov tshuaj muaj zog ntawm kev ruaj ntseg txawm tias muaj kev sov siab. Nws cov dej tsis kam tseem ceeb heev, nws yuav siv tau ntev ntev hauv 200 ° C dej vapor, thiab nws tuaj yeem siv tau rau ib lub sijhawm luv luv hauv 300 ° C siab siab dej haus. Vim tias cov saw hlau ntawm PEEK muaj qhov sib npaug ntawm benzene lub nplhaib, nws tuaj yeem nqus tau cov roj ntau ntau uas tsis muaj kev puas tsuaj, thiab cov hluav taws xob ua haujlwm kuj tseem ceeb heev.
