TPU (thermoplastic polyurethanes), ib thermoplastic tpu elastomer, yog ua kom muaj cov pab pawg ua haujlwm, thiab cov pab pawg ua haujlwm tau zoo. Vim nws zoo elasticity, zoo lub cev thiab cov kws kho tshuab zoo, nws yog dav siv hauv kev tsim cov txheej txheem, extrusion, calendolving rau hauv cov hom tshuaj-calendolving. Nws yog cov khoom siv yas feem ntau siv los ntawm kev lag luam yas ua.
Cov khoom ua tau npog cov ntau ntawm cov ntawv thov kev lag luam thiab cov pej xeem yam. Nyob rau hauv xyoo tsis ntev los no, vim kev txhim kho cov khoom lag luam tshiab, kev siv cov khoom siv thermoplastic pu elastomers tau txuas ntxiv rau kev lag luam yas nrog tus nqi qis thiab muaj nqi siab. TPU (Thermoplastic Polyurethane) yog nthuav dav rau nws cov neeg nyiam ua tau zoo thiab ib puag ncig. Qhov twg los PVC siv, TPU tuaj yeem dhau los ua ib qho hloov pauv rau PVC. Tab sis qhov zoo ntawm TPU yog dhau ntawm kev ncav cuag ntawm PVC.
TPU tsis yog muaj cov yam ntxwv ntawm qhov siab nro, lub zog siab, lub zog thiab kev laus tsis yog thiab ib puag ncig cov khoom siv. TPU tau siv dav hauv: Cov khoom siv khau, npaj-hnav, cov khoom siv khoom siv hauv qab, cov khoom siv tawv, cov khoom siv tawv, khoom siv dag zog, ua yeeb yam, txheej thiab lwm yam txheej txheem. Nws yog dav siv nyob rau hauv kis las khau: cov cim ua kom zoo nkauj rau kev kho kom zoo nkauj thiab uppers, airbags, cua cushions, roj hnab, thiab lwm yam.
Tam sim no, muaj ob txoj hauv kev ntawm TPU zaj duab xis hauv cov ntaub qhwv ntsej muag kis las, thiab cov duab kos duab loj los ntawm cov poj niam uas nrov tau los ntawm cov poj niam uas nrov, thiab cov duab kos rau sab saud, uas muaj cov nyhuv zoo thiab zoo nkauj. Qhov thib ob yog siv waterproof thiab noo noo-permeable tpu zaj duab xis kom haum rau cov ntaub qhwv khoom thiab dej noo-permeable.
