ʻO kahi ʻano plastic thermoplastic sa i hana ʻia mai nā resins polymer e lilo i wai homogenized ke hoʻomehana ʻia a paʻakikī ke hoʻomaʻalili ʻia. Eia naʻe, ke hoʻopaʻahau ʻia, lilo ka thermoplastic i mea aniani a hiki ke haki. ʻO kēia mau ʻano, ka mea e hāʻawi ai i ka inoa o ka mea, hiki ke hoʻohuli ʻia. ʻO ia hoʻi, hiki ke hoʻomehana hou ʻia, hoʻoponopono hou ʻia, a hoʻopaʻahau pinepine ʻia. ʻO kēia ʻano ke hana hou i nā thermoplastics. A, ʻo nā thermoplastics ke ʻano plastic i hoʻohana pinepine ʻia me Polyethelene (me HDPE, LDPE a me LLDPE), Polypropylene (PP), Polyvinyl Chloride (PVC), a me Polyethylene terephthalate (PET) ka mea i hoʻohana nui ʻia. ʻO nā hui ʻē aʻe o nā thermoplastics ʻo Acrylonitrile Butadiene Styrene (ABS), Ethylene Vinyl Acetate (EVA), Nylons (Polyamides) PA, Polystyrene (PS), Polymethyl Methacrylate (PMMA, acrylic), Thermoplastic Elastomers TPU TPE, TPR…

I kēia mau lā iho nei, ua nui ka nānā ʻana i ke kemika ʻōmaʻomaʻo me ka ulu wikiwiki ʻana o ka hoʻokele waiwai honua, ka hoʻonui ʻana i ka ʻike o ka poʻe e pili ana i ka palekana o ke kaiapuni, a me ke koi o kēlā me kēia kahua i ka maikaʻi a me ka hana o nā ʻāpana a me nā ʻāpana.
Ua hōʻoia ʻia e ʻimi ana nā mea hana o nā thermoplastics e hoʻomaikaʻi i nā helu extrusion, hoʻokō i ka hoʻopiha ʻana o ka mold mau, ka maikaʻi o ka ʻili maikaʻi loa, ka hoʻohana ʻana i ka mana haʻahaʻa, a kōkua i ka hōʻemi ʻana i nā kumukūʻai ikehu, me ka ʻole o ka hoʻololi ʻana i nā lako hana maʻamau, hiki iā lākou ke pōmaikaʻi mainā mea hoʻohui siliconee hana i nā ʻāpana ʻili nani maikaʻi loa, me ka COF haʻahaʻa, ka pale ʻana i ka abrasion a me ke kahakaha ʻana, ka manaʻo lima, a me ke kūpaʻa ʻana i nā ʻōpala, a me ke kōkua ʻana i kā lākou hana huahana e hoʻokō i kahi hoʻokele waiwai pōʻai.

ʻO ka ʻenehana holomua i ke kahua o nā mea hoʻohui silicone ka hoʻohana ʻana i ke kaumaha molekala ultra-kiʻekiʻe (UHMW)ka polymer silicone (PDMS)i nā mea lawe thermoplastic like ʻole a i ʻole nā ​​​​resins hana ʻia, e hoʻohui ana i ka hana maikaʻi loa me ke kumukūʻai kūpono.
ʻenehana SILIKEnā mea hoʻohui silicone,a i ʻoleka masterbatch siliconenā pellets a i ʻolepauka silikona,he maʻalahi ke hānai ʻia, a i ʻole ke kāwili ʻia, i loko o nā plastics i ka wā o ka hui ʻana, extrusion, a i ʻole ka hoʻoheheʻe ʻana i ka injection e hoʻonui i ka huahana e hoʻokō ai i ka wikiwiki o ke kaʻina hana, hoʻopau i ka pilikia o kekahi kūkulu ʻana o ka extruder, a hoʻomaikaʻi i ka maikaʻi o ka ʻili.
