Njengeplastiki yobunjineli eshushu enezakhiwo ezomeleleyo ezibanzi kwiminyaka yakutshanje, ibhodi yePOM isetyenziswa kakhulu kushishino lokwakha nakwishishini lokuvelisa. Abanye abantu bade bacinge ukuba ibhodi ye-POM inokutshintsha izinto zetsimbi ezifana nentsimbi, i-zinc, ubhedu kunye ne-aluminium. Ekubeni ibhodi ye-POM yiplastiki yobunjineli be-thermoplastic enendawo ephezulu yokunyibilika kunye ne-crystallinity ephezulu, kufuneka iguqulwe kwaye iphuculwe xa isetyenziswe kwiimeko ezahlukeneyo zesicelo.
Izinto ze-POM zineempawu zobunzima obuphezulu, ukuxhathisa ukunxiba, ukuxhathisa ukufuma, ukuxhathisa imichiza, njl. Inamandla okumelana ne-fuel, ukumelana nokudinwa, amandla aphezulu empembelelo, ukuqina okuphezulu, ukuxhathisa okuphezulu, ukuqina okuhle kwe-dimensional, i-self-lubricating, Inomlinganiselo ophezulu wenkululeko yoyilo kwaye ingasetyenziselwa ixesha elide kwi -40 ukuya kwi-100 °C. Nangona kunjalo, ngenxa yoxinano oluphezulu lwesalamane, amandla empembelelo ye-notched aphantsi, ukuxhathisa ubushushu akubi, ayifanelekanga i-flame retardant, ayifanelekanga ukuprintwa, kunye nesantya sokunciphisa ukubumba sikhulu, ngoko ke ukuguqulwa kwe-POM lukhetho olungenakuthintelwa. I-POM ilula kakhulu ukuyiqaqambisa ngexesha lenkqubo yokwenza kwaye ivelise ii-spherulites ezinkulu. Xa izinto zichaphazeleka, ezi spherulites ezinkulu zithande ukwenza amanqaku oxinzelelo kwaye zenze umonakalo wezinto eziphathekayo.
I-POM inovelwano lwenotshi ephezulu, amandla empembelelo yenotshi ephantsi, kunye nesantya esiphakamileyo sokucutheka. Imveliso ixhomekeke kuxinzelelo lwangaphakathi kwaye kunzima ukwenza ngokuqinileyo. Oku kunciphisa kakhulu usetyenziso lwe-POM kwaye alukwazi ukuhlangabezana neemfuno zoshishino kwezinye iinkalo. Ngoko ke, ukuze ulungelelanise ngcono kwiindawo zokusebenza ezinzima ezifana nesantya esiphezulu, uxinzelelo oluphezulu, ubushushu obuphezulu, kunye nomthwalo ophezulu, kunye nokwandisa ububanzi besicelo se-POM, kuyimfuneko ukuqhubela phambili ukuphucula Ukuqina kwempembelelo, ukuxhathisa ubushushu kunye nokuxhathisa ukuxhatshazwa kwe-POM.
Isihluthulelo sokuguqulwa kwe-POM kukuhambelana phakathi kwezigaba zenkqubo edibeneyo, kunye nophuhliso kunye nophando lwe-multifunctional compatibilizers kufuneka lwandiswe. Inkqubo yejeli esanda kuphuhliswa kunye ne-in-situ polymerized ionomer toughening yenza inkqubo edibeneyo yenze uthungelwano oluzinzile lwe-interpenetrating, oluyindlela entsha yophando yokusombulula ukuhambelana kwe-interphase. Isitshixo sokuguqulwa kweekhemikhali silele ekuqalisweni kwamaqela amaninzi kwi-chain chain chain ngokukhetha i-comonomers ngexesha lenkqubo yokudibanisa ukubonelela ngeemeko zokuguqulwa okuqhubekayo; ukulungelelanisa inani le-comonomers, ukulungelelanisa uyilo lwe-molecular structure, kunye nokudibanisa i-serialization kunye nokusebenza kunye ne-POM ephezulu yokusebenza.
