ʻO ka Thermoplastic Polyurethane (TPU) Resin no nā hihia kelepona paʻalima kiʻekiʻe TPU Granules TPU Pauda Mea Hana

ʻO TPU, pōkole no Thermoplastic Polyurethane, he elastomer thermoplastic kupaianaha me kahi ākea o nā waiwai koʻikoʻi a me kahi ākea o nā noi.

ʻO TPU kahi copolymer poloka i hana ʻia e ka hopena o nā diisocyanates me nā polyols. Aia ia me nā ʻāpana paʻakikī a palupalu. Hāʻawi nā ʻāpana paʻakikī i ka paʻakikī a me ka hana kino, ʻoiai nā ʻāpana palupalu e hāʻawi i ka maʻalahi a me nā hiʻohiʻona elastomeric.

Waiwai

• Na Waiwai Mechanical5: TPU kaena kiʻekiʻe ikaika, me ka tensile ikaika o a puni 30 - 65 MPa, a hiki ke hoʻomanawanui nui deformations, me ka elongation ma ka haʻihaʻi o 1000%. Loaʻa iā ia ke kūpaʻa abrasion maikaʻi loa, ʻoi aku ma mua o ʻelima mau manawa ʻoi aku ka ʻaʻahu - kūpaʻa ma mua o ka lāʻau kūlohelohe, a hōʻike i ke kūpaʻa waimaka kiʻekiʻe a me ke kūpaʻa koʻikoʻi - kūpaʻa, kūpono ia no nā noi e koi ana i ka ikaika mechanical kiʻekiʻe.

• Palekana Kemika5: Kūleʻa loa ka TPU i nā aila, nā momona, a me nā mea hoʻoheheʻe he nui. Hōʻike ia i ka paʻa maikaʻi i ka ʻaila hinu a me ka ʻaila mechanical. Eia kekahi, he kū'ē maikaʻi ia i nā kemika maʻamau, e hoʻonui ai i ke ola lawelawe o nā huahana i nā kaiapuni pili.

• Waiwai wela: Hiki i ka TPU ke hana pono i loko o ke ana wela mai - 40 °C a i 120 °C. Mālama ʻo ia i ka elasticity maikaʻi a me nā waiwai mechanical i nā haʻahaʻa haʻahaʻa a ʻaʻole e hoʻoheheʻe a hoʻoheheʻe maʻalahi i nā wela kiʻekiʻe.

• Na Waiwai e ae4: Hiki ke hoʻolālā ʻia ka TPU e hoʻokō i nā pae like ʻole o ka ʻike. ʻO kekahi mau mea TPU he mea akaka loa, a ma ka manawa like, mālama lākou i ka pale abrasion maikaʻi. Loaʻa i kekahi mau ʻano TPU ka hanu maikaʻi, me ka nui o ka lawe ʻana i ka mahu e hiki ke hoʻoponopono ʻia e like me nā koi. Eia kekahi, he biocompatibility maikaʻi loa ka TPU, ʻaʻole ia he mea ʻawaʻawa, ʻaʻohe allergenic, a me ka hoʻonāukiuki ʻole, kūpono ia no nā noi olakino.
