PEEK (polyether ether ketone), pulasitiki yapadera ya semi-crystalline, ili ndi ubwino monga mphamvu yayikulu, kukana kutentha kwambiri, kukana dzimbiri, komanso kudzipaka mafuta. PEEK polymer imapangidwa kukhala zinthu zosiyanasiyana za PEEK, kuphatikizapo PEEK granule ndi ufa wa PEEK, womwe umagwiritsidwa ntchito popanga mawonekedwe a PEEK, ziwalo za PEEK, ndi zina zotero. Zigawozi za PEEK zolondola zimagwiritsidwa ntchito kwambiri mu mafuta, magalimoto, ndege ndi zina.
PEEK CF30 ndi PEEK yodzazidwa ndi 30% ya kaboni yomwe imapangidwa ndi KINGODA PEEK. Kulimbitsa kwake ulusi wa kaboni kumathandiza kuti zinthuzo zikhale zolimba kwambiri. PEEK yolimbikitsidwa ndi ulusi wa kaboni imasonyeza mphamvu zambiri zamagetsi. Komabe, PEEK yolimbikitsidwa ndi ulusi wa kaboni 30% (PEEK5600CF30,1.4±0.02g/cm3) imakhala ndi kachulukidwe kochepa kuposa 30% ya ulusi wagalasi wodzazidwa ndi ulusi (PEEK5600GF30,1.5±0.02g/cm3). Kupatula apo, zinthu zopangidwa ndi ulusi wa kaboni nthawi zambiri sizimakanda kwambiri kuposa ulusi wagalasi pomwe nthawi yomweyo zimapangitsa kuti zikhale zovuta kuwononga ndi kukangana. Kuwonjezera ulusi wa kaboni kumatsimikiziranso kuti kutentha kumakhala kokwera kwambiri komwe kumathandizanso kuti zinthu zizikhala bwino nthawi zonse. PEEK yodzazidwa ndi kaboni imakhalanso yolimba kwambiri ku hydrolysis m'madzi otentha komanso nthunzi yotentha kwambiri.
