Loaʻa ka Ethylene-vinyl acetate copolymer (EVA) ma o ka copolymerizing ethylene a me vinyl acetate ma nā ʻāpana like ʻole. ʻO ka E ma ka pōkole Pelekania o EVA e hōʻike ana i ka ʻāpana ethylene, a ʻo VA e hōʻike ana i ka ʻāpana vinyl acetate. Ua like kona mau waiwai me nā vinyl acetate (VA). Pili loa ka ʻike, a hiki ke puʻunaue ʻia i ʻekolu mau māhele e like me ka ʻike VA: ʻO ka ʻike VA ma waena o 5% Chemicalbook a me 40% ua kapa ʻia ʻo EVA plastic, kahi i hoʻohana nui ʻia no ka hoʻololi ʻana i ka polyethylene, ka hana ʻana i nā uea a me nā kaula, nā kiʻiʻoniʻoni a me nā huahana i hoʻoheheʻe ʻia a me nā hui ʻana; ʻO ka ʻike VA ma waena o 40% a me 90% ua kapa ʻia ʻo EVA rubber, kahi i hoʻohana nui ʻia i ka rubber, nā kaula a me nā ʻāpana ʻoihana kaʻa; ʻO ka ʻike VA ma luna o 90% ua kapa ʻia ʻo polyvinyl acetate emulsion, kahi i hoʻohana nui ʻia i nā mea hoʻopili, nā uhi, a pēlā aku.

Loaʻa i ka Ethylene-vinyl acetate copolymer ke kūpaʻa maikaʻi i ka hopena a me ke kūpaʻa i ka haki ʻana o ke koʻikoʻi, palupalu, elasticity kiʻekiʻe, kū'ē i ka puncture a me ke kūpaʻa kemika, nā waiwai uila maikaʻi, biocompatibility maikaʻi, haʻahaʻa haʻahaʻa, a kūlike me nā mea hoʻopihapiha a me ka mea pale ahi. Loaʻa i ka mea hana ka hoʻohālikelike maikaʻi. Loaʻa iā EVA kahi ākea o nā noi ma muli o ka ʻike VA, mai ka plastic, a i ka rubber, a i ka latex. He kūpono ia no nā ʻano hana like ʻole e like me ka extrusion, injection molding, blow molding, coating, thermoforming, etc. Hiki ke hoʻopili ʻia i nā kaula, nā sila, nā lāʻau lapaʻau, nā kiʻiʻoniʻoni insulating, nā paipu, nā papa, nā mea kūkulu hale, nā mea pono uila, nā ʻāpana kaʻa a me nā mea pono o kēlā me kēia lā a me nā huahana ʻē aʻe.
