TPU (Thermoplastic polyurethanes) he mea ia ma waena o ka ʻōpala a me ka plastic.ʻO ka ʻaila a me ka wai kūpaʻa a he maikaʻi loa ka lawe ʻana a me ka hopena hopena.ʻO TPU kahi mea polimer non-toxic pili i ke kaiapuni.Loaʻa i nā mea Tpu nā pono o ka elasticity kiʻekiʻe o ka lāʻau a me ka hana ʻana o ka plastic.ʻAʻole pono ia i ka vulcanization a hiki ke hana ʻia e nā mīkini hoʻoheheʻe thermoplastic maʻamau.Hoʻopuka maʻalahi, thermoplastic elastomer tpu ua thermoformed a hiki ke hana ʻia me ka hoʻohana ʻana i nā mīkini hoʻoheheʻe injection, extruders, nā mīkini hoʻoheheʻe puhi.ʻO ka ʻōpala a me nā koena he 100% recyclable, ka mea maka i koho ʻia e hoʻololi i ka PVC, ka lāʻau a me ke silikoni a hoʻomalu i ka ʻoihana a me nā plastics.

Rubber: ʻO ka Rubber kahi polymer organik me ke kaumaha molekala o nā haneli haneli.Pono ka vulcanization e mālama i ka elasticity kiʻekiʻe ma ka pae wela o -50 a 150°C. Low elastic modulus, 3 kauoha o ka nui ma lalo o nā mea maʻamau, nui deformation, elongation hiki ke hiki i 1000% (mea maʻamau ma lalo o 1%), ua hoʻokuʻuʻia ka wela i ka wā o ke kaʻina hana, a piʻi ka elasticity me ka mahana,ʻo ia hoʻi. haʻahaʻa hoʻi ma mua o nā mea maʻamau ma ke ʻano ʻē.

ʻO ka ʻokoʻa ma waena o TPU a me ka rubber:

1. He palupalu ka Rubber, a he ākea loa ka laulā paʻakikī (0-100a) o ka mea tpu ma waena o ka pahu a me ka plastic;

2. He akea loa ka mana'o o ka elastomer, ua kapa 'ia ka tpu i ka rubber thermoplastic (tpr), a 'o ka rubber ka mea ma'amau i ka thermosetting rubber;

3. Heʻokoʻa nāʻano hana.Hoʻomaʻamaʻa ʻia ka Rubber ma ka hui ʻana i ka pahu, aʻo ka TPU maʻamau e hana ʻia e ka extrusion;

4. He okoa na waiwai.Pono ka Rubber e hoʻohui i nā mea hoʻohui like ʻole a pono e vulcanized no ka hoʻoikaika ʻana, ʻoiai maikaʻi loa ka hana tpu o nā elastomers thermoplastic;

5. He laina laina ko ka thermoplastic elastomer tpu a ua hoʻopili kino ʻia e ka hoʻopaʻa hydrogen.Nahā nā paʻa hydrogen i nā wela kiʻekiʻe a he plastic.Hoʻopili kemika i ka Rubber a ʻaʻole thermoplastic.

6. He maikaʻi loa ka pale lole TPU, ʻoi aku ia ma mua o ʻelima mau manawa ma mua o ke kopa maoli, a ʻo ia kekahi o nā mea i makemake ʻia no nā huahana pale.
