POM-C sheet ke semicrystalline thermoplastic 'me e khetholloa ke coefficient e tlaase ea likhohlano le thepa e ntle ea ho apara, le thepa e ntle ea ho apara, e sa ameheng ke libaka tse metsi.Poleiti ea POM e fana ka khanyetso e ntle ea lik'hemik'hale tse ngata tse kenyelletsang li-solvents tse ngata. Letlapa la Delrin le fana ka matla a phahameng le ho satalla ho kopantsoeng le mochini o bonolo. AHD e boetse e tsebahala ka matla a eona a phahameng a me-chanical, ho hanyetsa mocheso le thepa e ntle ea antifriction. A Bakeng sa likarolo tse hlokang ho tsitsa ka mokhoa o leka-lekaneng esita le ho pepesetsoa mongobo kapa tikolohong e mongobo, POM-C e fana ka metsi a chesang a betere, mocheso le lik'hemik'hale tse hanyetsanang le POM-H.
Ha ho tluoa tabeng ea ho hanyetsa lik'hemik'hale, maqephe a POM a ipabola. E na le khanyetso e phahameng ea li-solvents, mafura, oli le lik'hemik'hale tse ling tse ngata, e leng se etsang hore e be se loketseng bakeng sa likarolo tse kopanang le lintho tsena. Letlapa la POM le boetse le na le botsitso bo phahameng, ho bolelang hore e boloka sebopeho le boholo ba eona le tlas'a maemo a mocheso a feteletseng.
Molemo o mong oa maqephe a POM ke ho monya ha 'ona ha mongobo o tlase. Ho fapana le lipolasetiki tse ling tse ngata, POM e na le tšekamelo e tlase haholo ea ho monya mongobo, e amang thepa ea eona ea mochini le ea motlakase. Sena se etsa hore e loketse ho sebelisoa libakeng tse mongobo moo hygroscopicity e leng ngongoreho.

E 'ngoe ea likarolo tse hlahelletseng tsaLetlapa la POMke litšobotsi tsa eona tse khabane tsa ho thella. E na le coefficient e tlase ea khohlano, ho bolelang hore e thella habonolo holim'a libaka tse ling ntle le khanyetso e ngata. Sena se etsa hore e be khetho e tsebahalang bakeng sa lits'ebetso tse hlokang motsamao o boreleli, o se nang likhohlano, joalo ka likere, li-bearings le likarolo tse thellang.
Letlapa la POMs e boetse e na le khanyetso e phahameng ea ho sesa, e leng bohlokoa haholo lits'ebetsong tse kenyelletsang metsamao e pheta-phetoang ea mochini. E khona ho mamella ho senyeha ha nako e telele le likhohlano, ho etsa hore e tšoarelle. Ho phaella moo, POM ha e na tšekamelo ea ho qhekella, e bolelang hore e boloka sebōpeho le botsitso ba eona esita le tlas'a khatello ea nako e telele.
Machinability ke monyetla o mong oa maqephe a POM. E ka etsoa habonolo le ho etsoa ho sebelisoa mekhoa ea khale ea tlhahiso e kang ho sila, ho reteleha le ho cheka. Sena se lumella hore ho be bonolo ho hlahisa likarolo tse rarahaneng le tse nepahetseng. Letlapa la POM le boetse le na le thepa e ntle ea motlakase le dielectric, e etsang hore e tšoanelehe bakeng sa lits'ebetso tsa ho kenya motlakase.
At FEELA, re fana ka mefuta e mengata ea likhetho tsa POM. Lipampiri tsa rona tsa POM li entsoe ka thepa ea moroetsana e netefatsang boleng bo holimo le ts'ebetso. Li fumaneha ka mefuta e mengata ea botenya ho tloha ho 0.5mm ho ea ho 200mm, ka bophara bo tloaelehileng ba 1000mm le bolelele ba 2000mm. Re fana ka mebala e tšoeu le e ntšo, kapa re ka etsa mebala ho latela litlhoko tsa hau tse ikhethang.
Hore na o hloka maqephe a POM bakeng sa likarolo tsa mochini, li-insulator tsa motlakase kapa ts'ebeliso efe kapa efe, maqephe a rona a boleng bo holimo a POM a ka fihlela litlhoko tsa hau. Ka thepa ea bona e ntle ea mochini, khanyetso e phahameng ea lik'hemik'hale le botsitso ba sebopeho, maqephe a rona a POM a fana ka ts'ebetso e ikhethang le ho ts'epahala. Ikopanye le rona kajeno ho ithuta haholoanyane ka lihlahisoa tsa rona tsa maqephe a POM le hore na li ka u tsoela projeke ea hau molemo joang.
