Ethylene-vinyl acetate copolymer (EVA) imapezeka pophatikiza ethylene ndi vinyl acetate m'magawo osiyanasiyana. E mu chidule cha Chingerezi cha EVA imayimira gawo la ethylene, ndipo VA imayimira gawo la vinyl acetate. Kapangidwe kake ndi kofanana ndi ka vinyl acetate (VA). Zomwe zili mkati mwake zimagwirizana kwambiri, ndipo zitha kugawidwa m'magulu atatu malinga ndi kuchuluka kwa VA: kuchuluka kwa VA pakati pa 5% Chemicalbook ndi 40% kumatchedwa pulasitiki ya EVA, yomwe imagwiritsidwa ntchito kwambiri posintha polyethylene, kupanga mawaya ndi zingwe, mafilimu ndi zinthu zina zowumbidwa ndi zosakaniza; kuchuluka kwa VA pakati pa 40% ndi 90% kumatchedwa mphira wa EVA, womwe umagwiritsidwa ntchito kwambiri mu rabara, zingwe ndi zigawo zamagalimoto; kuchuluka kwa VA kopitilira 90% kumatchedwa polyvinyl acetate emulsion, komwe kumagwiritsidwa ntchito kwambiri mu zomatira, zokutira, ndi zina zotero.

Ethylene-vinyl acetate copolymer ili ndi mphamvu yabwino yolimbana ndi kupsinjika, kufewa, kusinthasintha kwakukulu, kukana kubowoka ndi kukhazikika kwa mankhwala, mphamvu zamagetsi zabwino, kusagwirizana bwino ndi zinthu zina, kutsika kwa kachulukidwe, ndipo imagwirizana ndi zodzaza ndi zoletsa moto. Chothandizirachi chimagwirizana bwino. EVA ili ndi ntchito zosiyanasiyana kutengera kuchuluka kwa VA, kuyambira pulasitiki, mpaka rabara, mpaka latex. Ndi yoyenera njira zosiyanasiyana zopangira monga extrusion, injection molding, blow molding, covering, thermoforming, ndi zina zotero. Itha kugwiritsidwa ntchito pa zingwe, Zisindikizo, zamankhwala, mafilimu oteteza kutentha, mapaipi, mbale, zipangizo zomangira, zowonjezera zamagetsi, zida zamagalimoto ndi zofunikira za tsiku ndi tsiku ndi zinthu zina.
