I-Polycarbonate diols iwuhlobo lwama-polyols anezakhiwo ezinhle kakhulu ezihlanganisayo, futhi amaketanga awo amangqamuzana aqukethe amayunithi aphindaphindayo asuselwa ku-carbonate. Eminyakeni yamuva nje, zibhekwa njengezinto zokusetshenziswa zesizukulwane esisha se-thermoplastic polyurethane elastomers. Ngakho-ke, njengengxenye ethambile, inokusebenza okuhle kakhulu kuzo zonke izici ze-polycarbonized TPU ehlanganiswe ne-isocyanate ne-chain extender.
Uma kuqhathaniswa ne-polyester TPU, ayinawo amandla aphezulu, ukumelana nokushisa okuphezulu nezinye izici, kodwa futhi inokumelana okuhle kakhulu kwe-hydrolysis. Uma iqhathaniswa ne-polyether TPU, ayinakho kuphela ukumelana ne-hydrolysis enhle kakhulu, kodwa futhi inamandla aphezulu, ukumelana nokushisa okungcono nokuzinza okungcono kwe-oxidation.
Ngenxa yokusebenza kwayo okuhle kakhulu, eminyakeni yamuva nje, i-TPU ye-polycarbonized isetshenziswe kabanzi ekukhiqizeni izimboni, izinto zokwelapha kanye neminye imikhakha. Ukusebenzisa ukumelana kwayo nokugqoka, amandla aphezulu, ukumelana nokushisa okuhle, ukumelana ne-hydrolysis, ingasetshenziswa njengamasondo angaphansi kwamanzi nezinye izinto ezikhethekile. Isebenzisa ukumelana ne-hydrolysis yayo, amandla aphezulu, ukumelana ne-oxidation, njll., ingakhiqiza amapayipi akhethekile amelana ne-chlorine neminye imikhiqizo yezimboni. Ngokumelana kwayo ne-oxidation okuhle kakhulu nokuzinza emzimbeni womuntu, ingasetshenziswa njengohlobo olusha lwempahla yokufakelwa kwezokwelapha.
Ngeminyaka eminingi yokuthuthukiswa kocwaningo nolwazi lokukhiqiza, i-Miracll ingakhiqiza ngokuzinza uchungechunge lokuqina lwe-80A-95A lwe-Polycarbonate TPU njenge-C80, C85, C90, C95.
Ngokuzayo, sizothuthukisa izinto ezintsha ezinhle kakhulu ngokwezinjongo nezimo ezahlukahlukene.
