Iipolycarbonate diols luhlobo lwepolyols kunye neempawu ezigqwesileyo ezibanzi, kwaye amatyathanga abo emolekyuli aqukethe iiyunithi eziphindaphindayo ezisekwe kwi-carbonate. Kwiminyaka yakutshanje, zijongwa njengezinto ezingasetyenziswanga zesizukulwana esitsha se-thermoplastic polyurethane elastomers. Ke ngoko, njengecandelo elithambileyo, linomsebenzi ogqwesileyo kuyo yonke imiba yepolycarbonized TPU eyenziwe nge-isocyanate kunye nechain extender.
Xa kuthelekiswa ne-polyester TPU, ayinayo kuphela amandla aphezulu, ukumelana nobushushu obuphezulu kunye nezinye iimpawu, kodwa inokumelana ne-hydrolysis ebalaseleyo. Xa kuthelekiswa ne-polyether TPU, ayinakuxhathisa i-hydrolysis ebalaseleyo kuphela, kodwa inamandla aphezulu, ukumelana nobushushu obungcono kunye nokuzinza okungcono kwe-oxidation.
Ngenxa yokusebenza kwayo okugqwesileyo, kwiminyaka yakutshanje, i-TPU ye-polycarbonized isetyenziswa ngokubanzi kwimveliso yemizi-mveliso, izixhobo zonyango kunye namanye amacandelo. Ukusebenzisa ukuxhathisa kwayo, amandla aphezulu, ukumelana nobushushu obuhle, ukuxhathisa i-hydrolysis, inokusetyenziswa njengamatayara angaphantsi kwamanzi kunye nezinye izinto ezikhethekileyo. Ukusebenzisa ukuxhathisa kwayo nge-hydrolysis, amandla aphezulu, ukuxhathisa i-oxidation, njl., inokuvelisa imibhobho ekhethekileyo yokumelana ne-chlorine kunye nezinye iimveliso zamashishini. Ngokuxhathisa kwayo okugqwesileyo kwe-oxidation kunye nokuzinza emzimbeni womntu, inokusetyenziswa njengohlobo olutsha lwemathiriyeli yokufakelwa kwezonyango.
Ngeminyaka emininzi yophuhliso lophando kunye namava emveliso, i-Miracll inokuvelisa ngokuzinzileyo i-80A-95A uchungechunge lobunzima be-Polycarbonate TPU njenge-C80, i-C85, i-C90, i-C95.
Kwixesha elizayo, siya kuphuhlisa izixhobo ezitsha ezigqwesileyo ngokweenjongo ezahlukeneyo kunye nokusingqongileyo.
