TPU Aliphatic

## 1、 **Aliphatic Thermoplastic Polyurethane(TPU Aliphatic)** O se elastomer thermoplastic maualuga le fa'atinoga ua fa'aputuina e fa'aaoga ai aliphatic diisocyanates o ni monomers autu o le vaega malo. O lona ivi molecular e leai ni mama manogi (mama benzene), ma e maua ai le tete'e sili atu i le UV, tete'e i le samasama, ma le tumau i le tau pe a fa'atusatusa i le aromatic TPU. **Vasega (e ala i le vaega vaivai)** – Polyester-based aliphatic TPU – Polyether-based aliphatic TPU – Polycarbonate-based aliphatic TPU **Monomers autu** – HDI (Hexamethylene Diisocyanate) – IPDI (Isophorone Diisocyanate) – H12MDI (4,4′-Methylenebis(cyclohexyl isocyanate))

## 2、（Meatotino Autū） 1. **Tete'e i le samasama ma le UV**：Tete'e tulaga ese i le ave o le UV ma le 'okesene; tausia le manino ma le mautu o le lanu mo le umi o le fa'aalia i fafo. 2. **Taugofie i le Tau**：Taofia le maualuga o le UV, vevela maualuga, susū, ma le soloia o vaila'au; umi le ola tautua (e masani ona >10 tausaga le tusi saisai). 3. **Meatotino fa'amekanika**：Fetuutuuna'i lelei, fetuutuuna'i, tete'e i le toe oso, tete'e i le olo, ma le malosi o le masae; lelei le fa'atinoga o le vevela maualalo. 4. **Meatotino va'ai**：Maualuga le manino, itiiti le puao, ma lelei le fesiita'iga o le malamalama (>92% i fa'aoga tioata laminated). 5. **Biocompatibility & hypoallergenic**：Telefoni mo le pa'i atu i le pa'u ma fa'aoga fa'afoma'i; leai se manogi ma e le fa'aita. 6. **Tete'e fa'amekanika**：Tete'e i suau'u, solvents, acids, alkalis, ma le hydrolysis. #

# 3、（e fa'atusatusa i le TPU manogi） | Uiga Fa'apitoa |TPU Aliphatic| TPU Manogi | | Fausaga Fa'akemikolo | Leai ni mama benzene; aliphatic diisocyanates (HDI, IPDI) | O lo'o iai mama benzene; aromatic diisocyanates (MDI, TDI) | | E tete'e i le samasama/UV | Sili ona lelei; leai se samasama i lalo o le UV | E faigofie ona samasama/fa'a'okesaita | | Malosi Fa'amekanika | Lelei le fetu'una'i/fetu'una'i; maualalo le ma'a'a | Maualuga le ma'a'a/malosi; sili atu le tete'e atu i le ofuina | | Tau | Maualuga | Maualalo | | Fa'aoga Autū | PPF maualuga, masini fa'afoma'i, ata opitika, totonu o ta'avale | Vaega lautele o alamanuia, tapuvae seevae, ata puipui maualalo |

## 4、（Fa'aoga Masani） 1. **Ta'avale** – Ata Puipui Vali (PPF) / peleue manino – Teuteuga i totonu (pa'u o mea faigaluega, vaega o nofoa) – Ata pupuni, ofutau fa'amalama, vaega tioata laminated 2. **Foma'i ma le Tausiga Soifua Maloloina** – Catheters faafoma'i, afifiina o mea faigaluega taotoga – Vaega e pa'i atu i le pa'u (fusi masini e mafai ona ofuina) – Vaega e mafai ona fa'amamā (121°C e fetaui ma le fa'amamāina i le ausa) 3. **Optics & Electronics** – Ata pupuni puipui manino maualuga, puipui lau – Vaega LED (ufiufi moli, ta'iala moli) – Pusa eletise fa'atau ma vaega ua uma ona fa'apipi'i 4. **Ta'aloga ma Oloa Fa'atau** – Midsole foamed mo seevae ta'aloga (maualalo le mafiafia, maualuga le fetu'una'i) – Mata tioata, fusi uati, ata pupuni puipui i fafo 5. **Fa'apisinisi** – Ata pupuni puipui luga, tioata ballistic – Vaega ua uma ona fa'apipi'i, ufiufi ie, vaega e tete'e i le ofuina

## 5、（Fa'agasologa & Fomu） – **Fomu**：Pellets, ata tifaga, laupepa, pauta – **Metotia fa'agasologa**：Fa'a'ofuofu tui, fa'a'ofuofu, fa'a'ofuofu ata tifaga, fa'a'ofuofu kalena, fa'a'ofuofu – **Lelei**：E fetaui ma le fa'agasologa masani o le thermoplastic; e maua le saoasaoa o le ta'amilosaga, tafe maualuga, ma le maualalo o le mafiafia
