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, linokusebenza okugqwesileyo 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 okuvelisa, i-Miracll inokuvelisa ngokuzinzileyo i-80A-95A uchungechunge lobulukhuni lwe-Polycarbonate TPU njenge-C80, i-C85, i-C90, i-C95.
Kwixesha elizayo, siya kuphuhlisa izixhobo ezitsha ezigqwesileyo ngokweenjongo ezahlukeneyo kunye nokusingqongileyo.
