PAMXD6多少钱一公斤？
这个问题一搜，从四十块一公斤到一百七十块一公斤，报价差得比MXDA含量还多。有人说我买的四十的国产通用用得挺好，有人说我买的一百七十的玻纤增强才叫高端。到底差在哪？
说实话，问PAMXD6多少钱一公斤的人，大概率还没搞懂PAMXD6这东西不是一个料——通用级、玻纤增强级、高阻隔级、耐高温级、碳纤维增强级，每个分支价格都不一样。你拿通用级的价和玻纤增强比，那不叫比价，叫被忽悠。
PAMXD6就是聚酰胺MXD6，间苯二甲胺和己二酸缩聚，半芳香尼龙，高阻隔、低吸水、耐高温，常用于食品包装、汽车发动机周边、电子电器、工业机械。
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。
三菱瓦斯化学（MGC，日本）
MXD6通用级，参考价约60-100元/公斤。食品包装、汽车、电子电器。
MXD6玻纤增强级，参考价约80-130元/公斤。结构件、汽车、工业机械。
MXD6碳纤维增强级，参考价约100-170元/公斤。高端结构件、导电应用、航空航天。
国产PAMXD6（中企大厂）
通用级，参考价约40-70元/公斤。性价比高，通用注塑、食品包装、汽车。
玻纤增强级，参考价约50-90元/公斤。结构件、汽车、工业机械。
高阻隔级，参考价约55-95元/公斤。食品包装、阻隔薄膜、饮料包装。
一句话总结：国产通用40-70块，国产玻纤增强50-90块，进口通用60-100块，进口玻纤增强80-130块，进口碳纤维增强100-170块。你要的是啥MXDA含量和性能，决定了你该在哪一档选。
二、同是PAMXD6，价差凭什么这么大
PAMXD6的价格差，主要藏在四个地方。
第一，MXDA纯度不同。工业级MXDA便宜，高纯度MXDA贵。高纯度MXDA决定了材料的阻隔性和耐热性，价格更高。
第二，增强方式不同。无筋通用便宜，玻纤增强适中，碳纤维增强贵。碳纤维增强比玻纤增强贵30-50%。
第三，阻隔等级不同。通用级便宜，高阻隔级贵。高阻隔需要特殊工艺，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。同样是玻纤增强，三菱瓦斯比国产贵30-50%，贵的是品控和研发。
三、采购避坑：别让MXDA骗了你
我见过太多采购，比价比到最后选了最便宜的四十的，然后做出来的制品阻隔差、耐热不够、客户退货，一次损失够买半年的好料。
PAMXD6采购这行，水比你想的深。三个坑必须绕开：
第一，看阻隔性和热变形温度不看牌号。同一个牌号不同批次性能可能波动，拿到料先测阻隔性和热变形温度，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PA6当PAMXD6卖，拿低MXDA含量当高含量卖。要COA、要MXDA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40块，做出来制品次品率5%；B料单价70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——比如要高阻隔又要耐高温、要玻纤增强又要高流动、要低成本又要食品级——那不是PAMXD6的问题，是你需要的不是标准PAMXD6，是改性PAMXD6。
这时候可以看看宁波科隆新材目前在做的高性能改性PAMXD6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PAMXD6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，PAMXD6行情一天一个样，间苯二甲胺、己二酸、玻纤、碳纤维、汇率都在动。
如果你需要三菱瓦斯、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PAMXD6这事儿，四十的和一百七十的，差的不是一百三十。
单价是门槛，选对MXDA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，是一公斤能做出高阻隔食品包装的方案。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 PAMXD6 per kilogram?
PAMXD6 is not one material: GF-reinforced, and each carries a different price.
1. Mainstream grade quotes (imported + domestic) — recent market references; live prices subject to same-day inquiry.
PAMXD6
approx. CNY 60-100/kg. food packaging; automotive; electronics.
approx. CNY 80-130/kg. structural parts; automotive; industrial machinery.
approx. CNY 100-170/kg. aerospace.
Domestic PAMXD6
general-purpose, approx. CNY 40-70/kg. general injection; food packaging; automotive.
GF-reinforced, approx. CNY 50-90/kg. structural parts; automotive; industrial machinery.
approx. CNY 55-95/kg. food packaging.
2. Why prices differ so much
Four factors: (1) composition — lower levels are cheaper; higher levels give better performance but cost more. (2) reinforcement — premium grades need special formulations and cost more. (3) application — 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 PAMXD6, you need a modified compound. Ningbo Kolong New Materials is developing high-performance modified PAMXD6 solutions covering glass-fiber reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified PAMXD6 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; PAMXD6 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.
