Nkag siab txog cov nuances ntawm TPU zaj duab xis, polyurethane zaj duab xis, thiab lwm yam thermoplastics yog qhov tseem ceeb rau cov kws tshaj lij kev lag luam txiav txim siab xaiv cov khoom. Thaum TPU (Thermoplastic Polyurethane) thiab polyurethane films tej zaum yuav zoo tib yam thaum xub thawj, qhov sib txawv me me ntawm lawv cov tshuaj muaj pes tsawg leeg thiab cov txheej txheem tsim khoom delineate lawv cov kev siv thiab kev ua tau zoo.
Chemical Composition thiab Manufacturing: TPU yog ib hom polyurethane thiab sib koom ntau yam khoom nrog polyurethane films. Txawm li cas los xij, TPU tau raug tsim los ua cov thermoplastic, txhais tau tias nws tuaj yeem yaj, zoo li, thiab rov ua kom muaj zog ntau zaus yam tsis muaj qhov cuam tshuam loj rau nws cov khoom. Cov tsoos polyurethane, thaum tseem muaj ntau yam, feem ntau dhau los ua cov txheej txheem thermosetting ib zaug, ua rau nws tsis tuaj yeem hloov pauv thiab rov ua dua tshiab.
Mechanical Properties: TPU cov yeeb yaj kiab feem ntau pom muaj qhov ua tau zoo dua qub, ua haujlwm tsis zoo, thiab elasticity piv rau cov qauv polyurethane films. Qhov no ua rau TPU tsim nyog rau cov ntawv thov uas xav tau kev ua haujlwm siab thiab hloov tau yooj yim, xws li hauv kev tsim cov dej hloov pauv hloov pauv lossis cov khaub ncaws ua kis las siab.
Environmental Resistance: Ob qho khoom siv tiv taus roj, roj, thiab ntau yam tshuaj. Txawm li cas los xij, TPUs tuaj yeem muaj qhov sib txawv ntawm qhov kub thiab txias, tswj kev ncaj ncees hauv cov dej khov thiab kub, uas tsis yog ib txwm muaj nrog cov yeeb yaj kiab polyurethane.
Biocompatibility: Qee qib ntawm TPU tshwj xeeb yog tsim los ua biocompatible, ua rau lawv qhov kev xaiv zoo tshaj plaws rau kev siv kho mob uas cuam tshuam nrog tib neeg cov ntaub so ntswg. Txawm hais tias cov tshuaj polyurethane tshwj xeeb tuaj yeem ua tau raws li biocompatible, TPU qhov ntau ntawm kev kho mob-qib kev xaiv yog dav dua.
Piv txwv li, lwm yam thermoplastics xws li PVC lossis PE tuaj yeem muab qhov zoo ntawm cov nqi lossis cov cuab yeej ntsuas tshwj xeeb xws li pob tshab lossis hluav taws xob rwb thaiv tsev tab sis feem ntau tsis muaj kev sib xyaw ua ke ntawm kev hloov pauv, ua haujlwm ntev, thiab kev tiv thaiv uas TPU muab. Yog li ntawd, kev nkag siab txog cov kev sib txawv no tso cai rau kev xaiv cov khoom siv raws li qhov kev xav tau tshwj xeeb, ntsuas cov yam ntxwv xws li kev ua tau zoo, kev xav txog ib puag ncig, thiab kev txwv nyiaj txiag.
