Ethylene-vinyl acetate copolymer (EVA) imapezeka mwa copolymerizing ethylene ndi vinyl acetate mosiyanasiyana. E mu chidule cha Chingerezi cha EVA imayimira gawo la ethylene, ndipo VA imayimira chigawo cha vinyl acetate. Makhalidwe ake ndi ofanana ndi a vinyl acetate (VA). Zomwe zili ndizogwirizana kwambiri, ndipo zimatha kugawidwa m'magulu atatu malinga ndi zomwe zili VA: VA zili pakati pa 5% Chemicalbook ndi 40% zimatchedwa pulasitiki ya EVA, yomwe imagwiritsidwa ntchito kwambiri pokonzanso polyethylene, mawaya opanga mawaya ndi zingwe, mafilimu ndi zina zoumbidwa. mankhwala ndi zosakaniza; VA zomwe zili pakati pa 40% ndi 90% zimatchedwa mphira wa EVA, womwe umagwiritsidwa ntchito makamaka mu mphira, zingwe ndi zigawo zamakampani agalimoto; VA zili pamwamba 90% amatchedwa polyvinyl acetate emulsion, amene makamaka ntchito zomatira, zokutira, etc.

Ethylene-vinyl acetate copolymer ili ndi kukana kwabwino komanso kukana kupsinjika, kufewa, kutsika kwambiri, kukana kuphulika ndi kukhazikika kwamankhwala, mphamvu zamagetsi zamagetsi, biocompatibility yabwino, kachulukidwe kakang'ono, ndipo imagwirizana ndi zodzaza ndi zoziziritsa kukhosi. Wothandizira ali ndi kuyanjana kwabwino. EVA ili ndi ntchito zosiyanasiyana kutengera zomwe zili mu VA, kuyambira pulasitiki, mphira, mpaka latex. Ndi oyenera njira zosiyanasiyana processing monga extrusion, jekeseni akamaumba, kuwomba akamaumba, ❖ kuyanika, thermoforming, etc. Iwo angagwiritsidwe ntchito zingwe, Zisindikizo, mankhwala, insulating mafilimu, mapaipi, mbale, zomangira, Chalk magetsi, mbali galimoto ndi zofunika tsiku ndi tsiku ndi zinthu zina
