Polycarbonate diols imhando ye polyols ine yakanakisa kuzadza zvivakwa, uye macheni awo emamorekuru ane carbonate-based repeating units. Mumakore achangopfuura, ivo vanoonekwa seyakagadzirwa zvigadzirwa zvechizvarwa chitsva che thermoplastic polyurethane elastomers. Naizvozvo, sechikamu chakapfava, chine hunyanzvi hwekuita mune ese maficha epolycarbonized TPU akagadzirwa ne isocyanate uye cheni extender.
Kuenzaniswa nepolyester TPU, haina chete simba rakakwirira, kupisa kwakanyanya uye humwe hunhu, asiwo ine yakanakisa hydrolysis kuramba. Kana ichienzaniswa nepolyether TPU, haina chete yakanakisa hydrolysis kuramba, asi zvakare ine simba rakakwirira, nani kupisa kupisa uye nani oxidation kugadzikana.
Nekuda kwekuita kwayo kwakanaka, mumakore achangopfuura, polycarbonized TPU yave ichishandiswa zvakanyanya mukugadzirwa kwemaindasitiri, zvekurapa uye mamwe minda. Ichishandisa kupfeka kwayo kupikisa, simba rakawanda, yakanaka kupisa kupisa, hydrolysis kuramba, inogona kushandiswa senge matai epasi pemvura uye zvimwe zvakakosha zvinhu. Ichishandisa yayo hydrolysis kuramba, simba rakawanda, oxidation kuramba, nezvimwewo, inogona kugadzira yakakosha chlorine inodzivirira pombi uye zvimwe zvigadzirwa zvemaindasitiri. Iine yakanakisa oxidation kuramba uye kugadzikana mumuviri wemunhu, inogona kushandiswa semhando nyowani yezvekurapa implant zvinhu.
Nemakore mazhinji ebudiriro yekutsvagisa uye ruzivo rwekugadzira, Miracll inogona kuburitsa 80A-95A kuoma kwakatevedzana kwePolycarbonate TPU senge C80, C85, C90, C95.
Mune ramangwana, isu tichagadzira zvimwe zvakanakisa zvinhu zvitsva zvinoenderana nezvinangwa zvakasiyana uye nharaunda.
