Ethylene - copolymer of ester of acetic acid ethylene (EthyleneVinylAcetate, abbreviation EVA) it is polyethylene of afterwards high density (HDPE) , low density polyethylene (LDPE) , polyethylene of linear low density (LLDPE) the polymer of series of the 4th big ethylene later. EVA colophony is in flexibility, optical sex, be able to bear or endure the respect such as microtherm sex, impact resistance has an advantage, have the characteristic such as hot sealing.

EVA production technology basically parts law of the type that it is boiler and tubal type way two kinds big. Law of traditional boiler type manufactures technology, content of ester of ethylene of EVA product acetic acid (VA% ) highest can amount to 35%~40% , the product applies at glue of filmy, hot frit, light volt, epispastic wait for many domains. But suffer device of type of boiler of be confined to to produce can small, and in recent years business dust overcomes patent of craft of boiler type law Sen Meifu stops technical accredit, line of current new increase production uses reason more law tubal form manufactures technology. relatively at craft of law of traditional boiler type, reaction of group of law tubal form is changed rate is higher (make an appointment with 10%~15% ) , cost of EVA product production is relative lower. In unit of production of current home EVA, unit of production of law tubal form is produced can occupy than about 61.7% .

EVA colophony applies in material of the film that pack, epispastic shoe, cable to wrap around widely film of glue of Fu, smooth hot season and the domain such as the glue that heat up frit. In addition, EVA colophony still can replace other resinous to reform profile expects, applied perspective is very wide.
Machine of outfit of global smooth hot season adds strip to change EVA colophony requirement quickly, predict global smooth hot season was 1.05 million tons to EVA resinous demand 2022, smooth 2025 hot season is 1.781 million tons to EVA resinous demand.
2022-2025 year global smooth hot season goes to EVA resinous demand situation

As science and technology progress reachs the rapid development of socioeconomy, the environmental protection consciousness of people increases subsequently, the environmental protection such as EVA colophony is harmless product more and more get consumer favors. At present home already introduced boiler type and tubal type two kinds of EVA manufacture technology, make be improved on the technology ceaselessly in producing a course, raise EVA unit yield, but the phase is realer EVA demand is put in huge gap as before. The dependence that China imports to EVA degree is opposite taller. The import volume of our country EVA achieved eleven billion one hundred and sixty-seven million tons 2021, and export volume will be seventy-one thousand three hundred tons only. 2022 1-10 month, the import volume of our country EVA achieves 9.892 billion tons, and export volume is ninety-four thousand four hundred tons.
2016-2022 year the amount of imports and exports of EVA of 1-10 month China goes situation

As our country smooth hot season green industry, can low smoke does not have bittern flame retardant cable and beforehand the development of film technology, it is important that Fu of solar battery, cable, besmear will become EVA resinous use a field, demand increases steadily. Prospective country gives aid to energetically clean energy project, demand of resinous of EVA of smooth hot season will increase quickly, continue to pull use development of whole EVA industry. Review overall situation, in answer to the country energy-saving decrease carbon, carbon to counteract wait for development policy, demand of colophony of the EVA in burgeoning industry increases will progressively promotion, demand of the EVA in traditional industry is reduced gradually.
Accompany home burgeoning industry, green can the high speed of the industry develops, structure of EVA market product will have change. Apply at the tradition the low end of farming film and epispastic shoe material share of EVA product market will be reduced further, product of hi-tech content EVA, the bend over that be like light, cable and demand of besmear Fu material will promote steadily. Economy of profit from low carbon promotes development of industry of the bend over that reach light, EVA market demand shows whole to rise steadily posture, development perspective is very wide. Additional, 945 during it is line of domestic EVA new increase production releases period centrally, the output that industry of colophony of current home EVA faces is insufficient, EVA entrance counts degree of tall state, hopeful gets ameliorative, share of entrance EVA market will be replaced stage by stage.
Prospect of market of EVA colophony industry how? Grind in all the net releases " 2023-2029 year market of Chinese EVA colophony is panoramic investigation and industrial competition pattern report " labor market of industry of colophony of EVA of relevant definition, whole world expands EVA colophony trade industry of colophony of EVA of environment of development of estate of colophony of EVA of the current situation, China, China moves, help enterprise and market of industry of colophony of investor understanding EVA invest value. If you think the knowledge that has a system to EVA colophony industry perhaps wants to invest EVA colophony industry, this report is your indispensable main tool.
