Njengeplastiki yobunjineli eshushu eneempawu eziqinileyo ezipheleleyo kwiminyaka yakutshanje, ibhodi yePOM isetyenziswa kakhulu kushishino lokwakha nakwishishini lokuvelisa. Abanye abantu bade bacinge ukuba ibhodi yePOM inokuthatha indawo yezinto zesinyithi ezifana nentsimbi, i-zinc, ithusi kunye ne-aluminium. Ekubeni ibhodi yePOM iyiplastiki yobunjineli ye-thermoplastic ene-melting point ephezulu kunye ne-crystallinity ephezulu, kufuneka iguqulwe kwaye iphuculwe xa isetyenziswa kwiimeko ezahlukeneyo zokusetyenziswa.
Izinto zePOM zineempawu zobunzima obuphezulu, ukumelana nokuguguleka, ukumelana nokufuma, ukumelana neekhemikhali, njl. Zinokumelana okunamandla kwamafutha, ukumelana nokudinwa, amandla aphezulu okuchaphazeleka, ukuqina okuphezulu, ukumelana okuphezulu kokuqhekeka, ukuzinza okuhle kobukhulu, ukuzithambisa, Zinenkululeko ephezulu yoyilo kwaye zingasetyenziswa ixesha elide kwi -40 ukuya kwi-100 °C. Nangona kunjalo, ngenxa yoxinano oluphezulu, amandla okuchaphazeleka aphantsi, ukumelana nobushushu kuphantsi, akufanelekanga kwi-larm retardant, akufanelekanga ukuprintwa, kwaye izinga lokuncipha kokubumba likhulu, ngoko ke ukuguqulwa kwePOM lukhetho olungenakuphepheka. I-POM kulula kakhulu ukuyibumba ngexesha lenkqubo yokwenza kwaye ivelise ii-spherulites ezinkulu. Xa izinto zichaphazeleka, ezi spherulites zikhulu zinokwakheka iindawo zoxinzelelo kwaye zibangele umonakalo kwizinto.
I-POM inovakalelo oluphezulu, amandla aphantsi empembelelo, kunye nesantya esiphezulu sokuncipha kokubumba. Le mveliso ithambekele ekuxinezelekeni kwangaphakathi kwaye kunzima ukuyibumba ngokuqinileyo. Oku kunciphisa kakhulu uluhlu lokusetyenziswa kwe-POM kwaye akunakuhlangabezana neemfuno zoshishino kwezinye iinkalo. Ke ngoko, ukuze ukwazi ukuziqhelanisa ngcono neendawo zokusebenza ezinzima ezifana nesantya esiphezulu, uxinzelelo oluphezulu, ubushushu obuphezulu, kunye nomthwalo ophezulu, kwaye wandise ngakumbi umda wokusetyenziswa kwe-POM, kuyimfuneko ukuphucula ngakumbi ukuqina kwempembelelo, ukumelana nobushushu kunye nokumelana nokungqubana kwe-POM.
Isitshixo sokuguqulwa kwe-POM kukuhambelana phakathi kwezigaba zenkqubo edibeneyo, kwaye uphuhliso kunye nophando lwezixhobo ezisebenzisanayo ezininzi kufuneka lwandiswe. Inkqubo yejeli entsha ephuhliswe kunye nokuqina kwe-ionomer e-polymerized in-situ kwenza inkqubo edibeneyo ibe yinethiwekhi ezinzileyo yokungena ngaphakathi, oluyisikhokelo sophando esitsha sokusombulula ukuhambelana phakathi kwesigaba. Isitshixo sokuguqulwa kweekhemikhali sisekungenisweni kwamaqela amaninzi kwimisebenzi kwikhonkco leemolekyuli ngokukhetha ii-comonomers ngexesha lenkqubo yokwenziwa ukuze kubonelelwe ngeemeko zokuguqulwa okungakumbi; ukulungisa inani lee-comonomers, ukuphucula uyilo lwesakhiwo seemolekyuli, kunye nokudibanisa i-serialization kunye nokusebenza kunye ne-POM esebenza kakhulu.
