TPE uwea VS TPU uwea

TPE(Thermoplastic Elastomer) he Thermoplastic Elastomer (Thermoplastic Elastomer) mea me ka ikaika kiʻekiʻe, kiʻekiʻe elasticity, injection molding, ākea ākea o nā noi, ka palekana o ke kaiapuni, non-toxic a palekana, a me ka waihoʻoluʻu maikaʻi loa.

TPU(Thermoplastic Urethane), i ʻike ʻia ma ka ʻōlelo Kina ʻo Thermoplastic polyurethane elastomer, he ʻano TPE.ʻO TPU kahi ʻano mea polymer i haku ʻia me ka diphenylmethane diisocyanate (MDI), toluene diisocyanate (TDI), macromolecular polyol a me ka mea hoʻonui kaulahao.

Ii.Nā ʻokoʻa ma waena o TPE a me TPU:

1. ʻOkoʻa Kaumaha Kūikawā:

TPE (0.89~1.3);

TPU (1.0~1.4);

2. ʻO kaʻokoʻa i kaʻaila kū'ē

ʻO ka TPE i ka aila kū'ē i kekahi degere o ka paʻakikī, akā maikaʻi, palupalu a maʻalahi;

He maikaʻi ka ʻaila kūʻē ʻo TPU, ikaika ka lima friction a me ka palupalu maikaʻi ʻole.

3. Nā ʻokoʻa o ka pale wela:

TPE (-60 ℃ ~105 ℃);

TPU (-60 ℃ ~80 ℃);

4. Nā ʻokoʻa o ke kūpaʻa a me ke kūpale ʻaʻahu:

ʻOi aku ka maikaʻi o ka TPU a me ka pale ʻana ma mua o TPE.

5. Nā ʻokoʻa o ka laulā paʻakikī:

TPE (0~100A);

TPU(35 ~ 90A, 50 ~ 80D),ʻo ka paʻakikī maʻamauʻo 80 ~ 95A.TPU me ka paʻakikī o 50 ~ 80D kakaikahi i hoʻohanaʻia i ka hana. ʻO nā hiʻohiʻona nui: ka laulā paʻakikī, a me ka piʻi ʻana o ka paʻakikī, mālama mau kāna mau huahana i ka elasticity maikaʻi a me ke kūpaʻa ʻana, ka ikaika mechanical kiʻekiʻe, ke kū ʻana o ke anuanu, ka hana hana maikaʻi, ka pale ʻana i ka aila, ka pale wai, ka pale ʻana, maikaʻi hana hou.
