Aliphatic TPU

## 1, **Aliphatic Thermoplastic Polyurethane(Aliphatic TPU)** Elastomer ya thermoplastic yogwira ntchito kwambiri yopangidwa pogwiritsa ntchito aliphatic diisocyanates ngati ma monomers ofunikira kwambiri. Msana wake wa molekyulu ulibe mphete za aromatic (mphete za benzene), zomwe zimapatsa mphamvu yolimbana ndi UV, anti-yellowing, komanso kupirira kwa nthawi yayitali poyerekeza ndi TPU ya aromatic. **Kugawa (ndi gawo lofewa)** – Polyester-based aliphatic TPU – Polyester-based aliphatic TPU – Polycarbonate-based aliphatic TPU **Key monomers** – HDI (Hexamethylene Diisocyanate) – IPDI (Isophorone Diisocyanate) – H12MDI (4,4′-Methylenebis(cyclohexyl isocyanate))

## 2、(Makhalidwe Aakulu) 1. **Kukana kwa chikasu ndi UV**：Kukana kwapadera ku kuwala kwa UV ndi okosijeni; kumasunga mawonekedwe owonekera komanso kukhazikika kwa utoto kuti ukhale panja kwa nthawi yayitali. 2. **Kutha kwa Nyengo**：Kupirira UV wambiri, kutentha kwambiri, chinyezi, ndi kukokoloka kwa mankhwala; moyo wautali (nthawi zambiri chitsimikizo cha zaka zoposa 10). 3. **Makhalidwe a makina**：Kusinthasintha kwabwino, kusinthasintha, kulimba kwa rebound, kukana kukwawa, ndi mphamvu yong'ambika; magwiridwe antchito abwino otentha pang'ono. 4. **Makhalidwe a kuwala**：Kuwonekera kwambiri, chifunga chochepa, komanso kufalikira kwa kuwala kwabwino (>92% mu magalasi opangidwa ndi laminated). 5. **Kugwirizana ndi zinthu zachilengedwe komanso kopanda ziwengo**：Koyenera kugwiritsidwa ntchito pakhungu ndi kuchipatala; kopanda fungo komanso kosakwiyitsa. 6. **Kukana kwa mankhwala**：Kulimbana ndi mafuta, zosungunulira, ma acid, alkali, ndi hydrolysis. #

# 3, (vs. Aromatic TPU) | Khalidwe |Aliphatic TPU| Aromatic TPU | | Kapangidwe ka Mankhwala | Palibe mphete za benzene; aliphatic diisocyanates (HDI, IPDI) | Muli mphete za benzene; aromatic diisocyanates (MDI, TDI) | | Anti-chikasu/UV | Zabwino kwambiri; palibe chikasu pansi pa UV | Zimakhala zachikasu/oxidation | | Mphamvu ya Makina | Kusinthasintha/kukhuthala kwabwino; kuuma kochepa | Kulimba/mphamvu kwambiri; kukana kuvala bwino | | Mtengo | Wapamwamba | Wotsika | | Kugwiritsa Ntchito Kwambiri | PPF yapamwamba, zipangizo zachipatala, mafilimu owonera, mkati mwa magalimoto | Zigawo zonse zamafakitale, nsapato, mafilimu oteteza otsika |

## 4, (Ntchito Zachizolowezi) 1. **Magalimoto** – Filimu Yoteteza Utoto (PPF) / bra yoyera – Zokongoletsa mkati (zikopa za zida, zigawo za mipando) – Mafilimu a pawindo, zida zowunikira padenga, magalasi olumikizidwa 2. **Zachipatala & Zaumoyo** – Ma catheter azachipatala, kulongedza zida zochitira opaleshoni – Zigawo zolumikizirana ndi khungu (zingwe zovalidwa) – Zigawo zoyeretsera (zogwirizana ndi 121°C zoyeretsera nthunzi) 3. **Optics & Electronics** – Mafilimu oteteza owonekera bwino, zoteteza pazenera – Zigawo za LED (zophimba kuwala, malangizo a kuwala) – Ma electronics ogwiritsidwa ntchito ndi zida zowombedwa 4. **Masewera & Katundu Wogwiritsidwa Ntchito** – Chovala chapakati cha thovu cha nsapato zamasewera (chochepa, chotanuka kwambiri) – Magalasi a maso, mawotchi, mafilimu oteteza akunja 5. **Mafakitale** – Mafilimu oteteza pamwamba, galasi lolimba – Zigawo zowumbidwa, zokutira nsalu, zigawo zosavala

## 5、(Kukonza ndi Mafomu) – **Mafomu**：Mapepala, mafilimu, mapepala, ufa – **Njira zokonzera**：Kupangira jekeseni, kutulutsa, kuphulitsa filimu, kuyika kalendala, kuyikanso zinthu zina – **Ubwino**：Kugwirizana ndi kukonza kwa thermoplastic; kuyendetsa mofulumira, kuyenda bwino, komanso kuchuluka kochepa komwe kulipo
