nā waiwai mechanical kiʻekiʻe PEI- Unfilled, GF, CF no ka uhi ʻana o nā huahana ʻoihana

ʻO ka Polyetherimide (PEI) he thermoplastic amorphous, amber-to-transparent me nā ʻano like me ka PEEK plastic pili. E pili ana i ka PEEK, ʻoi aku ka liʻiliʻi o ka PEI, akā ʻoi aku ka haʻahaʻa o ka ikaika hopena a me ka wela hoʻohana. Ma muli o kona mau waiwai pili a me ka paʻa kemika ua lilo ia i mea moe kaulana no nā mea paʻi FFF 3D.

ʻO ka mahana hoʻololi aniani o PEI he 217 °C (422 °F). ʻO kona mānoanoa amorphous ma 25 °C he 1.27 g/cm3(.046 lb/in³). He mea maʻalahi i ke koʻikoʻi i ka haki ʻana i nā solvents chlorinated. Hiki i ka Polyetherimide ke pale aku i nā wela kiʻekiʻe me nā waiwai uila paʻa ma luna o kahi ākea o nā alapine. Hāʻawi kēia mea ikaika kiʻekiʻe i ke kūpaʻa kemika maikaʻi loa a me nā waiwai ductile kūpono no nā noi like ʻole, ʻo ia hoʻi nā mea e pili ana i ka ʻike mahu.
