Ihe eji eme plastik PEEK-UNFILLED GF, CF maka ngwaọrụ ike

PEEK bụ thermoplastic nke ọkara kristal nwere ọmarịcha ọrụ na nguzogide kemịkalụ nke edobere na oke okpomọkụ. Ọnọdụ nhazi a na-eji akpụzi PEEK nwere ike imetụta crystalline na ya mere ihe eji arụ ọrụ. Modules nke ntorobịa ya bụ 3.6GPa na ike ike ya bụ 90 ruo 100 MPa.[5] PEEK nwere okpomoku mgbanwe iko nke gburugburu 143 Celsius (289 Celsius) wee gbazee gburugburu 343 Celsius (662 Celsius F). Ụfọdụ akara ule nwere uru ọ na-arụ ọrụ ruru 250 Celsius (482 Celsius F).[3] Nrụpụta ọkụ na-abawanye ihe fọrọ nke nta ka ọ bụrụ linear na ọnọdụ okpomọkụ dị n'etiti ọnụ ụlọ na okpomọkụ siri ike.[6] Ọ na-eguzogide nke ukwuu maka mmebi okpomọkụ, [7] yana ịwakpo ma gburugburu organic na aqueous. Halogens na Bronzed na Lewis acid siri ike wakporo ya, yana ụfọdụ ogige halogenated na aliphatic hydrocarbons na oke okpomọkụ. Ọ bụ soluble na sulfuric acid gbadoro anya na ụlọ okpomọkụ, ọ bụ ezie na mgbasa nwere ike iwe ogologo oge ma ọ bụrụ na polymer dị n'ụdị nwere oke elu-n'ebe dị elu, dị ka ezigbo ntụ ntụ ma ọ bụ ihe nkiri dị mkpa. Ọ nwere nnukwu iguzogide biodegradation.
