Njengepulasitiki yobunjiniyela eshisayo enezakhiwo eziqinile eziphelele eminyakeni yamuva nje, ibhodi le-POM lisetshenziswa kabanzi embonini yezokwakha kanye nemboni yokukhiqiza. Abanye abantu baze bacabange ukuthi ibhodi le-POM lingashintsha izinto zensimbi njengensimbi, i-zinc, ithusi ne-aluminium. Njengoba ibhodi le-POM liyipulasitiki yobunjiniyela be-thermoplastic enephuzu eliphakeme lokuncibilika kanye nekristalu ephezulu, idinga ukuguqulwa futhi ithuthukiswe lapho isetshenziswa ezimweni ezihlukene zohlelo lokusebenza.
I-POM impahla inezici zobulukhuni obuphezulu, ukumelana nokugqoka, ukumelana nomswakama, ukumelana namakhemikhali, njll. Inokumelana okuqinile kukaphethiloli, ukumelana nokukhathala, amandla omthelela aphezulu, ukuqina okuphezulu, ukumelana nokukhuphuka okuphezulu, ukuqina okuhle kwe-dimensional, ukuzithambisa, Inezinga eliphezulu lenkululeko yokuklama futhi ingasetshenziswa isikhathi eside ku -40 kuya ku-100 °C. Kodwa-ke, ngenxa yokuminyana okuphezulu okuhlobene, amandla omthelela we-notched aphansi, ukumelana nokushisa akulungile, akufanelekile ukubuyiswa komlilo, akufanelekile ukuphrinta, futhi izinga lokuncipha kokubumba likhulu, ngakho ukuguqulwa kwe-POM kuyisinqumo esingenakugwenywa. I-POM kulula kakhulu ukuyicwebezela ngesikhathi sokwenza futhi ikhiqize ama-spherulite amakhulu. Uma okubalulekile kuthinteka, lawa ma-spherulite amakhulu athambekele ekwenzeni izindawo zokugxilisa ingqondo futhi abangele ukulimala kokubalulekile.
I-POM inokuzwela kwenotshi ephezulu, amandla omthelela wenotshi ephansi, nezinga eliphezulu lokushwabana lokubumba. Umkhiqizo ujwayele ukucindezeleka kwangaphakathi futhi kunzima ukwakha ngokuqinile. Lokhu kunciphisa kakhulu umkhawulo wohlelo lokusebenza lwe-POM futhi akukwazi ukuhlangabezana nezidingo zezimboni kwezinye izici. Ngakho-ke, ukuze uvumelane kangcono nezimo zokusebenza ezinokhahlo njengejubane eliphezulu, ukucindezela okuphezulu, izinga lokushisa eliphezulu, nomthwalo ophezulu, futhi uqhubeke nokwandisa ububanzi besicelo se-POM, kuyadingeka ukuthuthukisa ngokwengeziwe Ukuqina komthelela, ukumelana nokushisa nokumelana nokungqubuzana kwe-POM.
Isihluthulelo sokuguqulwa kwe-POM ukuhambisana phakathi kwezigaba zohlelo oluyinhlanganisela, futhi ukuthuthukiswa nokucwaninga kwama-compatibilizer anemisebenzi eminingi kufanele kwandiswe. Isistimu yejeli esanda kuthuthukiswa kanye ne-in-situ polymerized ionomer toughening yenza isistimu eyinhlanganisela yakhe inethiwekhi ezinzile ehlanganayo, okuyindlela entsha yocwaningo yokuxazulula ukuhambisana kwe-interphase. Isihluthulelo sokuguqulwa kwamakhemikhali sisekwethulweni kwamaqembu emisebenzi eminingi kuchungechunge lwamangqamuzana ngokukhetha ama-comonomers phakathi nenqubo yokuhlanganisa ukuze kuhlinzekwe izimo zokuguqulwa okwengeziwe; ukulungisa inani lama-comonomers, ukuthuthukisa idizayini yesakhiwo samangqamuzana, kanye nokuhlanganisa uchungechunge nokusebenza kanye ne-POM esebenza kahle kakhulu.
