Loaʻa ka Ethylene-vinyl acetate copolymer (EVA) ma o ka copolymerizing ethylene a me vinyl acetate ma nā ʻano like ʻole. ʻO ka E ma ka ʻōlelo Pelekane ʻo EVA e hōʻike ana i ka ʻāpana ethylene, a ʻo VA ke ʻano o ka vinyl acetate component. Ua like kona mau waiwai me ka vinyl acetate (VA). Ua pili pili ka maʻiʻo, a hiki ke hoʻokaʻawale ʻia i ʻekolu mau ʻāpana e like me ka VA maʻiʻo: VA maʻiʻo ma waena o 5% Chemicalbook a me 40% i kapa ʻia ʻo EVA plastic, ka mea i hoʻohana nui ʻia no ka hoʻololi ʻana o ka polyethylene, nā uea hana a me nā kaula, nā kiʻiʻoniʻoni a me nā mea ʻē aʻe. nā huahana a me nā hui; ʻO ka ʻike VA ma waena o 40% a me 90% i kapa ʻia ʻo EVA rubber, ka mea i hoʻohana nui ʻia i ka pahu, nā kaula a me nā ʻoihana ʻoihana kaʻa; ʻO ka mea VA ma luna o 90% i kapa ʻia he polyvinyl acetate emulsion, ka mea i hoʻohana nui ʻia i nā adhesives, coatings, etc.

ʻO ka Ethylene-vinyl acetate copolymer ka hopena maikaʻi a me ke koʻikoʻi, ka palupalu, ka elasticity kiʻekiʻe, ke kūpaʻa puncture a me ka paʻa kemika, nā waiwai uila maikaʻi, biocompatibility maikaʻi, haʻahaʻa haʻahaʻa, a kūpono me nā mea hoʻopihapiha a me ke ahi retardant. He kūpono maikaʻi ka luna. Loaʻa i ka EVA ka nui o nā noi e pili ana i ka ʻike VA, mai ka plastic, ka lāʻau, 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. nā mea e pono ai i kēlā me kēia lā a me nā huahana ʻē aʻe
