TPU Aliphatic

## 1, **ʻO ka Polyurethane Thermoplastic Aliphatic(TPU Aliphatic)** He elastomer thermoplastic hana kiʻekiʻe i hana ʻia me ka hoʻohana ʻana i nā diisocyanates aliphatic ma ke ʻano he monomers ʻāpana paʻakikī koʻikoʻi. ʻAʻohe apo ʻala (nā apo benzene) i loko o kona iwi kuamoʻo molekala, e hāʻawi ana iā ia me ke kūpaʻa UV kiʻekiʻe, anti-yellowing, a me ka hiki ke kū i ka wā lōʻihi i hoʻohālikelike ʻia me ka TPU ʻala. **Ka Hoʻokaʻawale ʻana (e ka ʻāpana palupalu)** – Polyester-based aliphatic TPU – Polyether-based aliphatic TPU – Polycarbonate-based aliphatic TPU **Nā monomers koʻikoʻi** – HDI (Hexamethylene Diisocyanate) – IPDI (Isophorone Diisocyanate) – H12MDI (4,4′-Methylenebis(cyclohexyl isocyanate))

## 2、（Nā Waiwai Koʻikoʻi） 1. **Ke kū'ē i ka melemele a me ka UV**：Ke kū'ē kūikawā i ka radiation UV a me ka oxidation; mālama i ka transparency a me ke kūpaʻa o ke kala no ka hōʻike waho lōʻihi. 2. **Ke ʻano o ka wā**：Ke kū nei i ka UV kiʻekiʻe, ka mahana kiʻekiʻe, ka makū, a me ka ʻino kemika; ke ola lawelawe lōʻihi (pinepine >10 mau makahiki palapala hoʻokō). 3. **Nā waiwai mechanical**：ʻO ka maʻalahi maikaʻi loa, ka elasticity, ka rebound resilience, ke kū'ē i ka abrasion, a me ka ikaika haehae; hana maikaʻi haʻahaʻa-mahana. 4. **Nā waiwai optical**：Ke ʻano transparency kiʻekiʻe, ka noe haʻahaʻa, a me ka transmittance māmā maikaʻi (>92% i nā noi aniani laminated). 5. **Biocompatibility & hypoallergenic**：Kūpono no nā noi pili ʻili a me nā noi lapaʻau; ʻaʻohe ʻala a ʻaʻole hoʻonāukiuki. 6. **Ke kū'ē kemika**：Ke kū'ē i nā aila, nā solvents, nā waikawa, nā alkalis, a me ka hydrolysis. #

# 3、（vs. TPU ʻAla） | ʻAno |TPU Aliphatic| TPU ʻAla | | ʻAno Kemika | ʻAʻohe apo benzene; aliphatic diisocyanates (HDI, IPDI) | Loaʻa nā apo benzene; diisocyanates ʻala (MDI, TDI) | | Anti-melemele/UV | Maikaʻi loa; ʻaʻohe melemele ma lalo o UV | Maʻalahi i ka melemele/oxidation | | Ikaika Mechanical | Maʻalahi ka loli/elasticity; paʻakikī haʻahaʻa | ʻOi aku ka paʻakikī/ikaika; ʻoi aku ka maikaʻi o ke kūpaʻa ʻana i ka ʻaʻahu | | Kumukūʻai | Kiʻekiʻe | Haʻahaʻa | | Nā Hoʻohana Nui | PPF kiʻekiʻe, nā mea lapaʻau, nā kiʻiʻoniʻoni optical, nā mea o loko o ke kaʻa | Nā ʻāpana ʻoihana maʻamau, nā kapuaʻi kāmaʻa, nā kiʻiʻoniʻoni pale haʻahaʻa |

## 4、（Nā Hana Maʻamau） 1. **Kaʻa** – ʻAila Pale Pena (PPF) / pale umauma moakaka – ʻO ke kāhiko o loko (nā ʻili panela mea hana, nā ʻāpana noho) – Nā ʻili puka makani, pale kaua skylight, nā papa aniani laminated 2. **Lapaʻau & Mālama Ola** – Nā catheters lapaʻau, nā ʻōpala mea hana ʻoki kino – Nā ʻāpana pili ʻili (nā kaula mea hiki ke komo) – Nā ʻāpana sterilizable (121°C sterilization steam compatible) 3. **Optics & Electronics** – Nā ʻili pale moakaka kiʻekiʻe, nā pale pale – Nā ʻāpana LED (nā uhi kukui, nā alakaʻi kukui) – Nā hale uila mea kūʻai aku a me nā ʻāpana i hoʻoheheʻe ʻia 4. **Nā Haʻuki & Nā Waiwai Mea Kūʻai** – Midsole huʻa no nā kāmaʻa haʻuki (haʻahaʻa ka nui, elasticity kiʻekiʻe) – Nā maka aniani, nā kaula uaki, nā ʻili pale waho 5. **ʻOihana** – Nā ʻili pale ʻili, aniani ballistic – Nā ʻāpana i hoʻoheheʻe ʻia, nā uhi lole, nā ʻāpana pale ʻaʻahu

## 5、（Ka Hana ʻana & Nā ʻAno） – **Nā ʻAno**：Nā ʻiliʻili, nā kiʻiʻoniʻoni, nā pepa, nā pauka – **Nā ʻano hana**：Ka hoʻoheheʻe ʻana i ka inikini, ka hoʻokuʻu ʻana, ka puhi ʻana i ka ʻoniʻoni, ka hoʻopololei ʻana, ka hoʻoheheʻe ʻana i luna – **Nā Pōmaikaʻi**：Kūlike me ka hana ʻana i ka thermoplastic maʻamau; loaʻa nā pae kaʻapuni wikiwiki, ke kahe nui, a me ka haʻahaʻa haʻahaʻa
