Njengepulasitiki yobunjiniyela eshisayo enezakhiwo eziqinile eziphelele eminyakeni yamuva nje, ibhodi le-POM lisetshenziswa kabanzi embonini yokwakha kanye nemboni yokukhiqiza. Abanye abantu baze bacabange ukuthi ibhodi le-POM lingathatha indawo yezinto zensimbi ezifana nensimbi, i-zinc, ithusi kanye ne-aluminium. Njengoba ibhodi le-POM liyipulasitiki yobunjiniyela ye-thermoplastic enephuzu lokuncibilika eliphezulu kanye nekristali ephezulu, lidinga ukuguqulwa nokuthuthukiswa uma lisetshenziswa ezimweni ezahlukene zokusetshenziswa.
Izinto ze-POM zinezici zobulukhuni obuphezulu, ukumelana nokuguguleka, ukumelana nomswakama, ukumelana namakhemikhali, njll. Zimelana nophethiloli ngamandla, ukumelana nokukhathala, amandla aphezulu omthelela, ukuqina okuphezulu, ukumelana okuphezulu kokuhamba, ukuzinza okuhle kobukhulu, ukuzigcoba, Zinenkululeko yokuklama ephezulu futhi zingasetshenziswa isikhathi eside ku--40 kuya ku-100 °C. Kodwa-ke, ngenxa yobuningi obuphezulu, amandla omthelela aphansi, ukumelana nokushisa kubi, akufaneleki kokushisa okubamba ilangabi, akufaneleki ukuphrinta, futhi izinga lokuncipha kokubumba likhulu, ngakho-ke ukuguqulwa kwe-POM kuyisinqumo esingenakugwenywa. I-POM kulula kakhulu ukuyikhazimula ngesikhathi senqubo yokwakha futhi ikhiqize ama-spherulite amakhulu. Lapho izinto zithinteka, lawa ma-spherulite amakhulu athambekele ekwakheni amaphuzu okuhlushwa kokucindezeleka futhi abangele umonakalo wezinto.
I-POM inozwela oluphezulu, amandla aphansi omthelela, kanye nesilinganiso sokuncipha kokubumba okuphezulu. Umkhiqizo uthambekele ekucindezelekeni kwangaphakathi futhi kunzima ukwakheka kahle. Lokhu kunciphisa kakhulu ububanzi bokusetshenziswa kwe-POM futhi akukwazi ukuhlangabezana nezidingo zezimboni kwezinye izici. Ngakho-ke, ukuze uzivumelanise kangcono nezimo zokusebenza ezinzima njengesivinini esikhulu, umfutho ophezulu, izinga lokushisa eliphezulu, kanye nomthwalo ophezulu, futhi wandise ububanzi bokusetshenziswa kwe-POM, kubalulekile ukuthuthukisa ukuqina komthelela, ukumelana nokushisa kanye nokumelana nokungqubuzana kwe-POM.
Isihluthulelo sokuguqulwa kwe-POM ukuhambisana phakathi kwezigaba zesistimu ehlanganisiwe, futhi ukuthuthukiswa nocwaningo lwezihlanganisi eziningi ezisebenzayo kufanele kwandiswe. Uhlelo lwejeli olusanda kuthuthukiswa kanye nokuqina kwe-ionomer e-polymerized in-situ kwenza uhlelo oluhlanganisiwe lwakha inethiwekhi ezinzile yokungena, okuyisiqondiso esisha socwaningo sokuxazulula ukuhambisana kwesigaba. Isihluthulelo sokuguqulwa kwamakhemikhali sisekwethulweni kwamaqembu amaningi asebenzayo kuchungechunge lwama-molecule ngokukhetha ama-comonomer ngesikhathi senqubo yokuhlanganisa ukuze kuhlinzekwe izimo zokuguqulwa okuqhubekayo; ukulungisa inani lama-comonomer, ukwenza ngcono ukwakheka kwesakhiwo sama-molecule, kanye nokwenza i-serialization kanye nokusebenza kanye ne-POM esebenza kahle.
