Ngo-1958, i-Goodrich Chemical Company e-United States yaqala ukubhalisa iTPU imvelisouphawu Estane. Kule minyaka ingama-40 idlulileyo, zingaphezulu kwama-20 iibrendi zemveliso ziye zavela kwihlabathi jikelele, nganye inothotho lweemveliso. Okwangoku, abavelisi behlabathi behlabathi be-TPU babandakanya i-BASF, iCovestro, iLubrizol, iHuntsman, iMacintosh, iGaoding, njalo njalo.
Njenge-elastomer esebenza kakhulu, i-TPU inoluhlu olubanzi lwezalathiso zemveliso esezantsi kwaye isetyenziswa ngokubanzi kwiimfuno zemihla ngemihla, iimpahla zemidlalo, iithoyi, izixhobo zokuhombisa, kunye namanye amacandelo. Ngezantsi kukho imizekelo embalwa.
①Izixhobo zesihlangu
I-TPU isetyenziselwa ikakhulu izixhobo zezihlangu ngenxa yokuqina kwayo okugqwesileyo kunye nokumelana nokunxiba. Iimveliso zezihlangu eziqulethe i-TPU zikhululekile ngakumbi ukunxiba kuneemveliso zesihlangu eziqhelekileyo, ngoko ke zisetyenziswa kakhulu kwiimveliso zezihlangu eziphezulu, ngakumbi ezinye izihlangu zemidlalo kunye nezihlangu eziqhelekileyo.
② Imibhobho
Ngenxa yokuthamba kwayo, ukomelela okulungileyo, ukomelela kwempembelelo, kunye nokuxhathisa amaqondo obushushu aphezulu naphantsi, imibhobho yeTPU isetyenziswa kakhulu eTshayina njengemibhobho yerhasi neyeoyile yezixhobo zoomatshini ezifana neenqwelomoya, iitanki, iimoto, izithuthuthu, kunye nezixhobo zoomatshini.
③ Intambo
I-TPU ibonelela ngokumelana nokukrazula, ukuxhathisa ukunxiba, kunye neempawu zokugoba, kunye nokumelana nobushushu obuphezulu kunye nokuphantsi ngundoqo ekusebenzeni kwentambo. Ke kwimarike yaseTshayina, iintambo eziphambili ezinje ngeentambo zolawulo kunye neentambo zombane zisebenzisa i-TPU ukukhusela izixhobo zokugquma iintambo eziyiliweyo ezintsonkothileyo, kwaye izicelo zabo ziya zisanda.
④ Izixhobo zonyango
I-TPU yinto ekhuselekileyo, ezinzileyo, kunye nomgangatho ophezulu we-PVC othatha indawo ye-PVC engenazo iikhemikhali ezinobungozi ezifana ne-phthalates, ezinokufudukela egazini okanye kwezinye izinto ezimanzi ngaphakathi kwee-catheters zonyango okanye iingxowa kwaye zibangele iziphumo ebezingalindelekanga. Ikwalibakala eliphuhliswe ngokukodwa le-extrusion kunye nebakala lenaliti ye-TPU enokusetyenziswa ngokulula ngohlengahlengiso olungephi kwizixhobo ezikhoyo zePVC.
⑤ Izithuthi kunye nezinye iindlela zothutho
Ngokukhupha kunye nokugquma amacala omabini elaphu lenayiloni kunye ne-polyurethane thermoplastic elastomer, i-inflatable combat attack rafts kunye ne-reconnaissance rafts ethwele abantu be-3-15 inokwenziwa, kwaye ukusebenza kwabo kuphezulu kakhulu kune-raber evuzayo e-inflatable rafts; I-polyurethane thermoplastic elastomers eyomelezwe nge-fiberglass inokusetyenziselwa ukwenza amalungu omzimba anje ngeendawo ezibunjiweyo kumacala omabini emoto ngokwayo, izikhumba zamacango, ii-bumpers, ii-anti friction strips, kunye negriles.
