I-Thermoplastic polyurethane, evame ukubizwa ngokufushane ngokuthi i-TPU, ingenye yezinto zokwakha ezinobuchule obuningi kakhulu ezisetshenziswa ekukhiqizeni kwesimanje. Ingxenye yomndeni wama-elastomer, okusho ukuthi ihlanganisa ukuziphatha okunwebekayo kwerabha nokuqina nokuphila isikhathi eside kwepulasitiki. Lokhu kuhlanganiswa okukhethekile kwemvelo emibili kuvumela i-TPU ukuthi inwebe, igobe, futhi ibuyele esimweni sayo sokuqala kaningi ngaphandle kokuqhekeka noma ukulahlekelwa ukusebenza kahle. Ngokungafani nama-thermoset rubber athola ukwelashwa kwamakhemikhali okungenakuhlehliswa, i-thermoplastic polyurethane ingancibilikiswa, ibunjwe kabusha, futhi isetshenziswe futhi, okwenza ihehe kakhulu ekukhiqizweni ngezinga elikhulu lezimboni. Emashumini eminyaka ambalwa adlule, i-TPU iye yathatha indawo yezinto zendabuko ezifana ne-PVC, i-natural rubber, ne-nylon ezinkulungwaneni zezinhlelo zokusebenza, kusukela kumakesi omakhalekhukhwini kuya ezingxenyeni zezimoto. Ukukhula kwayo ekuthandeni kubonisa ushintsho olubanzi lwezimboni olubheke ezixazululweni zepholima ezisebenza kahle kakhulu, ezilula, nezingavuselelekayo ezingahlangabezana nezidingo eziqinile zobunjiniyela. Kunoma ibhizinisi elifuna ukuthuthukisa umugqa walo womkhiqizo, ukuqonda amandla angempela ale elastomer emangalisayo isinyathelo sokuqala ekwenzeni izinqumo ezihlakaniphile zokukhetha izinto.

Umlando we-thermoplastic polyurethane ubuyela emuva eminyakeni yakamuva ka-1930, lapho ososayensi beqala ukuhlola i-chemistry ye-polyurethane eJalimane. Kwaze kwaba ngawo-1960 nawo-1970 lapho amazinga e-TPU okuhweba atholakala kabanzi, eqhutshwa ubuchwepheshe ekuhlanganiseni ama-polymer obuvumela ukulawula okunembile kokuqina nokunwebeka. Emashumini eminyaka, abakhiqizi bamakhemikhali bacwengisiswa ukwakheka kwama-molecule e-TPU, bethula imindeni ye-polyester ne-polyether enikeza izinzuzo ezihlukile ezindaweni ezahlukene. Namuhla, i-thermoplastic polyurethane ithathwa njengokukhethwa okuphezulu embonini yepulasitiki ngoba inikeza ukumelana nokugqokwa okuhle kakhulu, amandla okudabula, nokunwebeka kuyilapho ihlala icutshungulwa kalula. Idlula i-PVC ekunwebekeni emazingeni okushisa aphansi, idlula irabha ekumelaneni nokugqokwa, futhi inikeza izinzuzo zokugaywa kabusha ezingenziwa kalula yi-nylon nezinye izingqapheli zobunjiniyela. Lezi zakhiwo zenze i-TPU yaba yinto ekhethwayo emikhiqizweni edinga ukusebenza kahle nokusimama. Noma ngabe wenza amashubhu ezokwelapha, izivalo zezimboni, noma izicathulo ezinemfashini, le-elastomer inikeza inhlanganisela elinganiselayo yamandla emishini nenkululeko yokuklama okungavamile ukuthi ezinye izinto zikwazi ukuyiphinda.

Ezingeni lamangqamuzana, i-thermoplastic polyurethane yakhiwe ngezingxenye ezintathu eziyinhloko: i-diisocyanate, i-polyol enochungechunge olude, kanye ne-chain extender enochungechunge olufushane. Lezi zingxenye zokwakha ziyasabela zakhe isakhiwo se-polymer esihlukanisiwe esinamasegimenti aqinile nathambile, futhi lolu hlaka lwezakhiwo yilokho okunika i-TPU ububanzi bayo obumangalisayo bezakhiwo. Amasegimenti aqinile ahlinzeka ngamandla, ukuqina, nokumelana nokushisa, kuyilapho amasegimenti athambile ehlinzeka ngokunwebeka, ukuguquguquka, nokumunca umthelela. Ngokulungisa isilinganiso salawa masegimenti, abakhiqizi bangakha amazinga e-TPU asukela ezintweni ezithambile kakhulu, ezifana nerabha, kuya kumapulasitiki aqinile, acwebezelayo anamazinga aphezulu obulukhuni. Lokhu kuguquguquka kuyisizathu esiyinhloko esenza i-thermoplastic polyurethane ikwazi ukusebenzela izimboni eziningi ezahlukene ngohlelo olulodwa lwekhemistri. Futhi kusho ukuthi ukukhetha izinga elifanele kudinga ukucatshangelwa ngokucophelela kwesicelo esiqondiwe kanye nezidingo zemishini ezobekwa engxenyeni yokugcina.

I-TPU ivamise ukuhlukaniswa ngemindeni emibili emikhulu: esekelwe ku-polyester ne-esekelwe ku-polyether, ngayinye inikeza amazinga ahlukene okusebenza. Amazinga e-polyester TPU agqama ekumelaneni nokugqokwa, amandla okudonsa, kanye nokumelana namafutha nezincibilikisi, okwenza afaneleke emasondweni, emahosini, nezingxenyeni zezimboni. Amazinga e-polyether TPU, ngakolunye uhlangothi, anikeza ukumelana okuphezulu nokubola kwamanzi, ukuguquguquka emazingeni aphansi okushisa, kanye nokumelana nokuhlaselwa amagciwane, okwenza abe ukukhethwa okuthandwayo ezinhlelweni zasolwandle, zezokwelapha, nezangaphandle. Ngaphandle kwalezi zigaba ezimbili, abakhiqizi baphinde banikeze amazinga akhethekile anokumelana nomlilo, ukubonakala, ukuzinza kwe-UV, nokunamathela okuthuthukisiwe kokubunjwa phezu kwezinye izinto. Izakhiwo ezibonakalayo nezomshini ezifana nokuqina kwe-Shore, ukubuyela emuva kokunwebeka, ukucindezelwa, namandla okudabula, konke kungaklanywa ngokunembile ukuze kuhambisane nezidingo zamakhasimende. Uma kuqhathaniswa nezinye izinto, i-TPU ibonisa ngokungaguquki ukumelana okungcono nokugqokwa kune-PVC nerabha, ukunwebeka okuphezulu kune-nylon, nokusebenza okungcono emazingeni aphansi okushisa kunezinto eziningi ezijwayelekile zepulasitiki.
