Polyurethane Thermoplastic (TPU) Hoʻolauna

Thermoplastic polyurethane (TPU) he ʻano polymer no ka ʻohana o nā elastomers thermoplastic. He mea maʻalahi ia i ʻike ʻia no kona kūpaʻa kiʻekiʻe, ka maʻalahi, a me ke kūʻē ʻana i nā ʻaila, nā momona, a me ka abrasion.

TPU hana ʻia ma ka hoʻohui ʻana i kahi diisocyanate (kahi ʻano o ka mea hoʻohuihui) me kahi polyol (kahi ʻano waiʻona). Hiki ke hoʻoheheʻe a hoʻoheheʻe hou ʻia ka mea hopena repeno laila, kūpono ia no ka hoʻohana ʻana i ka hoʻoheheʻe ʻana a me nā kaʻina extrusion.

TPU hoʻohana maʻamau ʻia i nā ʻano hana like ʻole, me ka hana ʻana i nā kāmaʻa, nā mea haʻuki, nā ʻāpana kaʻa, nā mea lapaʻau, a me nā mea uila uila. Hoʻohana pinepine ʻia ʻo ia ma ke ʻano he mea uhi, no ka mea hiki iā ia ke hāʻawi i kahi pale pale i hiki ke maʻalahi a paʻa.

ʻO kekahi o nā pono nui o Thermoplastic polyurethane (TPU) ʻo ia kona hiki ke hana ʻia no ka loaʻa ʻana o ka nui o nā waiwai kino, e like me ka paʻakikī, elasticity, a me ke kū'ē ʻana i nā kemika. ʻO kēia ka mea i mea nui loa i hiki ke hoʻopili ʻia e hoʻokō i nā koi noi kikoʻī.
