Aliphatic TPU

## 1, **Aliphatic Thermoplastic Polyurethane(Aliphatic TPU)** Ib qho thermoplastic elastomer ua tau zoo heev uas tau tsim los ntawm kev siv aliphatic diisocyanates ua cov monomers tseem ceeb. Nws cov molecular backbone tsis muaj aromatic rings (benzene rings), ua rau nws tiv taus UV zoo dua, tiv thaiv kev daj, thiab tiv taus huab cua ntev dua piv rau aromatic TPU. **Kev Faib Tawm (los ntawm cov ntu mos)** – Polyester-based aliphatic TPU – Polyether-based aliphatic TPU – Polycarbonate-based aliphatic TPU **Cov monomers tseem ceeb** – HDI (Hexamethylene Diisocyanate) – IPDI (Isophorone Diisocyanate) – H12MDI (4,4′-Methylenebis(cyclohexyl isocyanate))

## 2, (Cov Khoom Tseem Ceeb) 1. **Tiv Thaiv Kev Yellowing & UV Tsis kam**: Kev tiv thaiv zoo rau UV hluav taws xob thiab oxidation; tswj kev pom tseeb thiab xim ruaj khov rau kev raug sab nraum zoov ntev. 2. **Kev Tiv Thaiv Huab Cua**: Tiv taus UV siab, kub siab, av noo, thiab tshuaj lom neeg; lub neej ua haujlwm ntev (feem ntau >10 xyoo warranty). 3. **Cov khoom siv kho tshuab**: Kev ywj pheej zoo heev, elasticity, rebound resilience, abrasion tsis kam, thiab lub zog tsim kua muag; kev ua haujlwm zoo hauv qhov kub qis. 4. **Cov khoom siv kho qhov muag**: Kev pom tseeb siab, tsis muaj pos huab, thiab lub teeb xa mus zoo (>92% hauv cov ntawv thov iav laminated). 5. **Biocompatibility & hypoallergenic**: Haum rau kev sib cuag ntawm daim tawv nqaij thiab kev siv kho mob; tsis muaj ntxhiab thiab tsis khaus. 6. **Kev tiv thaiv tshuaj lom neeg**: Tiv taus roj, cov kuab tshuaj, kua qaub, alkalis, thiab hydrolysis. #
