EEA多少钱一公斤？
这个问题一搜，从十四块一公斤到三十五块一公斤，报价差得比丙烯酸乙酯含量还多。有人说我买的十四的国产通用用得挺好，有人说我买的三十五的进口高粘性才叫高端。到底差在哪？
说实话，问EEA多少钱一公斤的人，大概率还没搞懂EEA这东西不是一个料——通用级、高粘性级、高弹性级、热熔级、改性级，每个分支价格都不一样。你拿通用级的价和高粘性比，那不叫比价，叫被忽悠。
EEA就是乙烯丙烯酸乙酯共聚物，由乙烯和丙烯酸乙酯共聚制得，高粘性、高弹性、低温韧性好，常用于热熔胶、改性剂、包装、电线电缆、汽车。
一、主流牌号报价（外企+中企）
先把市面上走量的牌号和参考价摆出来。以下为近期市场参考价，实时价格以当日询价为准。
进口EEA（外企大厂）
通用级，参考价约20-28元/公斤。热熔胶、改性剂、包装。
高粘性级，参考价约25-32元/公斤。高端热熔胶、复合膜、特殊应用。
高弹性级，参考价约28-35元/公斤。汽车、电线电缆、特殊应用。
国产EEA（中企大厂）
通用级，参考价约14-22元/公斤。性价比高，热熔胶、改性剂、包装。
高粘性级，参考价约18-26元/公斤。高端热熔胶、复合膜、特殊应用。
改性级，参考价约16-25元/公斤。塑料改性、汽车、电线电缆。
一句话总结：国产通用14-22块，国产高粘性/改性16-26块，进口通用20-28块，进口高粘性/高弹性25-35块。你要的是啥丙烯酸乙酯含量和性能，决定了你该在哪一档选。
二、同是EEA，价差凭什么这么大
EEA的价格差，主要藏在四个地方。
第一，丙烯酸乙酯含量不同。低含量便宜，高含量贵。含量越高，粘性和弹性越好，但价格更高。
第二，粘性等级不同。通用级便宜，高粘性级贵。高粘性需要特殊含量，价格更高。
第三，弹性等级不同。通用级便宜，高弹性级贵。高弹性需要特殊配方，价格更高。
第四，品牌和产地。进口溢价高但批次稳定，国产性价比高但牌号少。同样是高粘性级，进口比国产贵30-50%，贵的是品控和研发。
三、采购避坑：别让丙烯酸乙酯含量骗了你
我见过太多采购，比价比到最后选了最便宜的十四的，然后做出来的制品粘性差、弹性差、客户退货，一次损失够买半年的好料。
EEA采购这行，水比你想的深。三个坑必须绕开：
第一，看熔融指数和剥离强度不看牌号。同一个牌号不同批次性能可能波动，拿到料先测熔融指数和剥离强度，和COA对得上再用。别听销售说"差不多"，差不多就是差很多。
第二，警惕以次充好。有些贸易商拿EVA当EEA卖，拿低含量当高含量卖。要COA、要丙烯酸乙酯含量检测、要原厂包装，三证合一才敢用。
第三，别只比单价，算综合成本。A料单价14块，做出来制品次品率5%；B料单价22块，次品率1%。算到每件制品上，B料反而更便宜。
四、标准牌号满足不了？看看改性方案
如果你发现标准牌号怎么选都差点意思——比如要高粘性又要高弹性、要低温韧性又要耐热、要低成本又要特殊级——那不是EEA的问题，是你需要的不是标准EEA，是改性EEA。
这时候可以看看宁波科隆新材目前在做的高性能改性EEA方案，玻纤增强、阻燃、耐候、导电这些方向都有对应牌号在做。有特殊需求的可以私信要一份改性EEA的报价参考，比自己买基料再加助剂调试，省的不只是钱，还有试错的时间。
说白了，标准料是大锅饭，改性料是定制菜。你的制品要求越高，越需要定制。
五、常用牌号，私信给你当日报价
上面的价格都是参考价，EEA行情一天一个样，乙烯、丙烯酸乙酯、催化剂、功能助剂、汇率都在动。
如果你需要进口、国产这些品牌的具体牌号当日报价，私信我，发你一份实时价格表。不绕弯子，报实数。
写在最后
买EEA这事儿，十四的和三十五的，差的不是二十一。
单价是门槛，选对丙烯酸乙酯含量和性能才是底线。别让报价单上的数字迷惑了你——你买的不是一公斤塑料，是一公斤能做出高粘性热熔胶的方案。把账算到每件制品上，再加上次品退货损失，你才知道谁真便宜谁真贵。

How much is EEA per kilogram?
Quotes range from CNY 14/kg to CNY 35/kg. EEA (ethylene-ethyl acrylate copolymer) is not one material: general-purpose, high-adhesion, high-elasticity, hot-melt and modified grades each carry a different price. Comparing a general-purpose quote with a high-adhesion one is not price comparison; it is how you get fooled.
EEA offers strong adhesion, high elasticity and good low-temperature toughness, and is used in hot-melt adhesives, modifiers, packaging, wire and cable, and automotive parts.
1. Mainstream grade quotes (imported + domestic) — recent market references; live prices subject to same-day inquiry.
Imported EEA (overseas majors)
General-purpose, approx. CNY 20-28/kg. Hot-melt adhesives, modifiers, packaging.
High-adhesion, approx. CNY 25-32/kg. Premium hot-melt adhesives, laminating films, special applications.
High-elasticity, approx. CNY 28-35/kg. Automotive, wire and cable, special applications.
Domestic EEA (Chinese majors)
General-purpose, approx. CNY 14-22/kg. Cost-effective; hot-melt adhesives, modifiers, packaging.
High-adhesion, approx. CNY 18-26/kg. Premium hot-melt adhesives, laminating films, special applications.
Modified grade, approx. CNY 16-25/kg. Plastics modification, automotive, wire and cable.
In short: domestic general-purpose CNY 14-22, domestic high-adhesion/modified CNY 16-26, imported general-purpose CNY 20-28, imported high-adhesion/high-elasticity CNY 25-35. Your required EA content and performance decide which tier you belong in.
2. Why prices differ so much
Four factors: (1) EA content — higher content means better adhesion and elasticity but a higher price. (2) Adhesion grade — high-adhesion needs special content levels. (3) Elasticity grade — high-elasticity needs special formulations. (4) Brand and origin — imports carry a premium but offer batch stability; for the same grade, imports cost 30-50% more than domestic, paying for quality control and R&D.
3. Procurement pitfalls
Cheapest-material buyers often end up with poor adhesion and elasticity, returns, and a loss equal to half a year of good material. Three traps to avoid:
First, test melt flow index and peel strength against the COA instead of trusting the grade name — same grade can fluctuate between batches. Second, watch for substitution fraud: some traders sell EVA as EEA or low-content as high-content; demand the COA, an EA-content test and original packaging. Third, calculate total cost, not unit price: A at CNY 14/kg with a 5% defect rate vs. B at CNY 22/kg with 1% — B is cheaper per finished part.
4. Standard grades not enough? Consider modified compounds
If standard grades always fall short — high adhesion AND high elasticity, low-temperature toughness AND heat resistance — you need modified EEA. Ningbo Kolong New Materials is developing high-performance modified EEA grades covering glass-fiber reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified EEA quote reference — it saves money and trial-and-error time.
In plain terms: standard grades are a big pot of shared rice; modified compounds are a dish cooked to order.
5. Same-day quotes via message
EEA prices change daily — ethylene, EA, catalysts and exchange rates all move. Message us for same-day quotes on specific imported or domestic grades; no beating around the bush, real numbers.
Final words
The gap between CNY 14 and CNY 35 is not CNY 21. Unit price is the threshold; choosing the right EA content and performance is the baseline. You are not buying a kilogram of plastic — you are buying a solution for making high-adhesion hot-melt adhesive. Do the math per finished part, add rejected-goods loss, and you will know who is truly cheap.
