PEEK-UNFILLED GF ea lintho tse bonahalang ea polasetiki, CF bakeng sa lisebelisoa tsa motlakase

PEEK ke semi crystalline thermoplastic e nang le lisebelisoa tse ntle haholo tsa ho hanyetsa lik'hemik'hale tse bolokiloeng mochesong o phahameng.Maemo a ts'ebetso a sebelisoang ho bopa PEEK a ka susumetsa kristale mme ka hona thepa ea mochini.Modulus ea eona e nyane ke 3.6 GPa mme matla a eona a thata ke 90 ho isa ho 100 MPa.[5]PEEK e na le mocheso oa phetoho ea khalase o ka bang 143 °C (289 °F) 'me e qhibiliha ho pota 343 °C (662 °F).Limaraka tse ling li na le mocheso o sebetsang o fihlang ho 250 °C (482 °F).[3]The mogote conductivity eketseha hoo e ka bang linearly le mocheso pakeng tsa mocheso kamoreng le solidus thempereichara.[6]E hanana haholo le ho senyeha ha mocheso,[7] hammoho le ho hlaseloa ke tikoloho ea tlhaho le e nang le metsi.E hlaseloa ke li-halogens le li-asiti tse matla tsa Bronzed le Lewis, hammoho le metsoako e meng ea halogenated le aliphatic hydrocarbons ka mocheso o phahameng.E qhibiliha ka sulfuric acid e concentrated ka mocheso oa kamore, le hoja ho qhibiliha ho ka nka nako e telele haholo ntle le haeba polymer e le ka sebōpeho se nang le tekanyo e phahameng ea sebaka-ho-volume, e kang phofo e ntle kapa filimi e tšesaane.E na le khanyetso e phahameng ea biodegradation.
