Ma ke ʻano he mea kahiko, ua paʻa loa nā mea PVC ma Kina, a ke hoʻohana nei ka hapa nui o nā mea hoʻohana. Ma ke ʻano he ʻano mea polymer hou, ʻo TPE kahi hoʻomaka hope ma Kina. ʻAʻole ʻike maikaʻi ka poʻe he nui i nā mea TPE. Eia naʻe, ma muli o ka ulu wikiwiki ʻana o ka hoʻokele waiwai i nā makahiki i hala iho nei, ua piʻi mālie ka nui o ka ʻai ʻana o nā kānaka. Me ka ulu wikiwiki o ka home, i ka ʻike ʻana o ka poʻe he pono lākou e ʻoi aku ka maikaʻi o ke kaiapuni a me ke kaiapuni, e piʻi mālie ka noi no nā mea TPE i ka wā e hiki mai ana.
ʻO ka TPE ka mea maʻamau i kapa ʻia he elastomer thermoplastic. E like me ka manaʻo o kona inoa, loaʻa iā ia nā hiʻohiʻona o nā thermoplastics, hiki ke hana a hoʻohana ʻia i nā manawa he nui. Loaʻa iā ia ka elasticity kiʻekiʻe o ka vulcanized rubber, a he mea pili i ke kaiapuni a ʻaʻole ʻona. Loaʻa iā ia kahi ākea ākea o ka paʻakikī, ʻo ia hoʻi, he pā palupalu a me ka hana maikaʻi loa. Colorability, hiki ke hoʻokō i nā koi o nā ʻano hiʻohiʻona like ʻole, ʻoi aku ka maikaʻi o ka hana ʻana, ka hana kiʻekiʻe o ka hoʻoponopono ʻana, hiki ke hana hou ʻia e hōʻemi i nā kumukūʻai, hiki ke hoʻoheheʻe ʻia i ʻelua pana, a hiki ke uhi ʻia a hoʻopaʻa ʻia me PP, PE, PC, PS. , ABS a me nā mea matrix ʻē aʻe. Hiki nō hoʻihoʻoheheʻe ʻiakaawale. Hoʻohana nui ia i nā mea e pono ai i kēlā me kēia lā, nā mea pāʻani, nā huahana uila, nā kaʻa a me nā ʻoihana ʻē aʻe.
ʻO ka mea PVC he polyvinyl chloride. ʻO nā mea PVC nā hiʻohiʻona o ke kaumaha māmā, ka wela wela, ka mālama ʻana i ka wela, ka moisture-proof, flame-retardant, hana maʻalahi a me ke kumu kūʻai haʻahaʻa. No laila, hoʻohana nui ʻia i nā mea hana. ʻO ka plasticizer i hoʻohuiʻia i ka mea PVC he meaʻawaʻawa ia, e hoʻokuʻu i nā meaʻawaʻawa ma lalo o ka puhi ahi a me ka wela kiʻekiʻe, he meaʻino ia i ke kino kanaka a me ke kaiapuni kūlohelohe.
Ke kākoʻo nei nā ʻāina a puni ka honua i ka hoʻokele waiwai haʻahaʻa haʻahaʻa a me ke ola kūlohelohe, ʻoi aku ka nui o nā wahi i kūkulu ʻia ma ʻEulopa a me ʻAmelika i pāpā i nā mea PVC, ʻo TPE ka mea kūpono loa e pani i ka PVC, e like me nā mea pāʻani, nā mea e pono ai i kēlā me kēia lā a me nā noi ʻē aʻe. Hoʻokō pū ʻo TPE i nā kūlana hoʻāʻo like ʻole e pili ana i ka pale ʻana i ke kaiapuni, a ʻoi aku ka maikaʻi o kāna mau huahana ma mua o PVC inā no ke kālepa kūloko a i ʻole. ʻAʻole hiki ke ʻōlelo ʻia ʻoi aku ka maikaʻi o TPE ma mua o PVC. ʻO ka mea nui loa e pili ana i kāu noi, e like me ka huahana, nā kumukūʻai a pēlā aku.
