Diols-yada polycarbonate waa nooc ka mid ah polyols leh sifooyin dhammaystiran oo aad u wanaagsan, silsiladahooda molecular waxay ka kooban yihiin unugyo soo noqnoqda oo kaarboonboon-ku-saleysan.Sanadihii la soo dhaafay, waxaa loo arkaa inay yihiin alaabta ceeriin ee jiilka cusub ee elastomer polyurethane thermoplastic.Sidaa darteed, sida qayb jilicsan, waxay leedahay waxqabad aad u fiican dhammaan dhinacyada TPU-ga polycarbonized oo lagu sameeyay isocyanate iyo silsilad fidiyaha.
Marka la barbardhigo polyester TPU, ma aha oo kaliya inay leedahay awood sare, caabbinta kulaylka sare iyo sifooyinka kale, laakiin sidoo kale waxay leedahay iska caabin aad u fiican.Marka la barbardhigo polyether-ka TPU, kaliya maaha inay leedahay iska caabin aad u fiican, laakiin sidoo kale waxay leedahay awood sare, iska caabbinta kulaylka wanaagsan iyo xasilloonida oksaydhka.
Iyadoo ay ugu wacan tahay waxqabadkeeda wanaagsan, sannadihii la soo dhaafay, TPU polycarbonized ayaa si aad ah loogu isticmaalay wax soo saarka warshadaha, qalabka caafimaadka iyo qaybaha kale.Isticmaalka caabbinta xirashada, xoogga sare, caabbinta kulaylka wanaagsan, caabbinta hydrolysis, waxaa loo isticmaali karaa sida taayirada biyaha hoostooda iyo qalab kale oo gaar ah.Isticmaalka caabbinta hydrolysis, xoogga sare, caabbinta oksaydhka, iwm, waxay soo saari kartaa tuubooyinka u adkaysta koloriin gaar ah iyo alaabada kale ee warshadaha.Iyada oo iska caabbinta oksaydhka iyo xasilloonida jidhka bini'aadamka ee aad u fiican, waxaa loo isticmaali karaa nooc cusub oo ah walxo daawaynta.
Sannado badan oo cilmi-baaris ah iyo waayo-aragnimada wax-soo-saarka, Miracll waxay si adag u soo saari kartaa 80A-95A taxane adag oo Polycarbonate TPU sida C80, C85, C90, C95.
Mustaqbalka, waxaanu soo saari doonaa agab cusub oo aad u wanaagsan iyadoo loo eegayo ujeedooyin iyo deegaan kala duwan.
