环氧树脂多少钱一公斤?
这个问题一搜,从十五块一公斤到四十块一公斤,报价差得比环氧值还多。有人说我买的十五的国产通用用得挺好,有人说我买的四十的进口高端才叫高纯度。到底差在哪?
说实话,问环氧树脂多少钱一公斤的人,大概率还没搞懂环氧树脂这东西不是一个料——双酚A型、酚醛型、脂环族型、溴化型、水性型,每个分支价格都不一样。你拿双酚A型的价和脂环族型比,那不叫比价,叫被忽悠。
环氧树脂就是含两个以上环氧基团的高分子化合物,粘接性强、耐腐蚀、电绝缘,常用于胶粘剂、涂料、电子封装、复合材料、地坪。
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。
进口环氧树脂(外企大厂)
双酚A型通用级,参考价约20-30元/公斤。胶粘剂、涂料、地坪。
酚醛型高环氧值,参考价约25-38元/公斤。电子封装、复合材料、耐高温应用。
脂环族型,参考价约30-40元/公斤。户外应用、耐高温、高耐候。
国产环氧树脂(中企大厂)
双酚A型通用级,参考价约15-24元/公斤。性价比高,胶粘剂、涂料、地坪。
酚醛型高环氧值,参考价约18-30元/公斤。电子封装、复合材料、耐高温应用。
溴化阻燃型,参考价约20-32元/公斤。电子电器、阻燃应用。
一句话总结:国产双酚A 15-24块,国产酚醛/溴化18-32块,进口双酚A 20-30块,进口酚醛/脂环族25-40块。你要的是啥环氧值和性能,决定了你该在哪一档选。
二、同是环氧树脂,价差凭什么这么大
环氧树脂的价格差,主要藏在四个地方。
第一,环氧值不同。低环氧值便宜,高环氧值贵。环氧值越高,交联密度越高,性能越好,但价格越高。
第二,类型不同。双酚A型便宜,酚醛型适中,脂环族型贵。类型越特殊,合成成本越高,价格越贵。
第三,纯度不同。工业级便宜,电子级贵。电子级需要高纯度,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。同样是酚醛型,进口比国产贵30-50%,贵的是品控和研发。
三、采购避坑:别让环氧值骗了你
我见过太多采购,比价比到最后选了最便宜的十五的,然后做出来的制品粘接差、固化不完全、客户退货,一次损失够买半年的好料。
环氧树脂采购这行,水比你想的深。三个坑必须绕开:
第一,看环氧值和粘度不看牌号。同一个牌号不同批次性能可能波动,拿到料先测环氧值和粘度,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。有些贸易商拿低环氧值当高环氧值卖,拿工业级当电子级卖。要COA、要环氧值检测、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15块,做出来制品次品率5%;B料单价24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——比如要高粘接又要耐高温、要高纯度又要低粘度、要低成本又要阻燃——那不是环氧树脂的问题,是你需要的不是标准环氧树脂,是改性环氧树脂。
这时候可以看看宁波科隆新材目前在做的高性能改性环氧树脂方案,增韧、增强、耐候、阻燃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环氧树脂的报价参考,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,环氧树脂行情一天一个样,双酚A、环氧氯丙烷、苯酚、固化剂、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
买环氧树脂这事儿,十五的和四十的,差的不是二十五。
单价是门槛,选对环氧值和性能才是底线。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接胶粘剂的方案。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 per kilogram?
is not one material: different grades, and each carries a different price.
1. Mainstream grade quotes (imported + domestic) — recent market references; live prices subject to same-day inquiry.
Imported
approx. CNY 20-30/kg. adhesives; coatings.
approx. CNY 25-38/kg.
approx. CNY 30-40/kg. outdoor applications; high-temperature.
Domestic
approx. CNY 15-24/kg. adhesives; coatings.
approx. CNY 18-30/kg.
approx. CNY 20-32/kg. electronics.
2. Why prices differ so much
Four factors: (1) composition — lower levels are cheaper; higher levels give better performance but cost more. (2) type — premium grades need special formulations and cost more. (3) purity — special applications need special formulations or certification and cost more. (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
The cheapest material often fails on performance and triggers customer returns. Three traps to avoid:
First, test key properties against the COA instead of trusting the grade name — performance of the same grade can fluctuate between batches. Second, watch out for substitution fraud: some traders pass off cheaper or recycled material as the real thing; demand the COA, a test report and original packaging before use. Third, don't compare unit price alone — calculate total cost per finished part, including rejected-goods loss; a higher-priced grade with a 1% defect rate is often cheaper than a low-priced one with 5% rejects.
4. Standard grades not enough? Consider modified compounds
If standard grades always fall short — for example you need flame retardancy AND high transparency, reinforcement AND chemical resistance, or low cost AND food grade — you don't need standard , you need a modified compound. Ningbo Kolong New Materials is developing high-performance modified solutions covering glass-fiber reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified quote reference — it saves not only money but also trial-and-error time.
In plain terms: standard grades are a big pot of shared rice; modified compounds are a dish cooked to order. The higher your requirements, the more you need customization.
5. Popular grades — same-day quotes via message
All prices above are references; prices change daily as feedstocks and exchange rates move. If you need same-day quotes for specific grades, message us and we will send a live price sheet. No beating around the bush — real numbers.
Final words
Unit price is the threshold; choosing the right grade and performance is the baseline. Do the math per finished part, add rejected-goods loss, and you will know who is truly cheap and who is truly expensive.
