PA6/6T多少钱一公斤？
这个问题一搜，从三十块一公斤到七十块一公斤，报价差得比6T含量还多。有人说我买的三十的国产通用用得挺好，有人说我买的七十的巴斯夫KR 4355 G7才叫耐电痕高端。到底差在哪？
说实话，问PA6/6T多少钱一公斤的人，大概率还没搞懂PA6/6T这东西不是一个料——通用级、玻纤增强级、阻燃级、耐电痕级、耐高温级，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。
PA6/6T就是聚酰胺6/6T，半芳香族尼龙，耐高温、低吸水、耐电痕，常用于汽车发动机周边、电子电器、SMT连接器、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。
巴斯夫（BASF，德国）
Ultramid T KR 4355 G7，玻纤增强PA6/6T耐电痕耐高温，参考价约50元/公斤。汽车、电子电器、连接器。
Ultramid T KR 4355 G10，高玻纤增强级，参考价约50-70元/公斤。高端结构件、汽车、工业机械。
Ultramid T系列，通用级，参考价约40-60元/公斤。通用注塑、汽车、电子。
EMS（瑞士）
Grivory PA6/6T系列，通用级，参考价约50-80元/公斤。汽车、电子、精密零件。
Grivory PA6/6T玻纤增强级，参考价约60-90元/公斤。高端结构件、汽车、连接器。
杜邦（DuPont，美国）
Zytel HTN系列，耐高温PA6T/66，参考价约50-80元/公斤。汽车发动机周边、电子电器、SMT连接器。
国产PA6/6T（中企大厂）
国产通用级，参考价约30-45元/公斤。性价比高，通用注塑、汽车、电子。
国产玻纤增强级，参考价约35-55元/公斤。结构件、汽车、连接器。
一句话总结：国产通用30-45块，国产玻纤增强35-55块，进口通用40-60块，进口玻纤增强/耐电痕50-90块。你要的是啥6T含量和性能，决定了你该在哪一档选。
二、同是PA6/6T，价差凭什么这么大
PA6/6T的价格差，主要藏在四个地方。
第一，6T含量不同。6T含量20%左右便宜，含量50%以上耐高温但贵。6T含量越高，耐热性越好，熔点越高。
第二，玻纤增强不同。无筋通用便宜，30%玻纤增强贵。玻纤增强比通用级贵20-30%。
第三，功能改性不同。阻燃、耐电痕、耐高温——这些都要加钱。特殊功能需要特殊配方。
第四，品牌和产地。进口溢价高但批次稳定，国产性价比高但高端牌号少。同样是玻纤增强，巴斯夫比国产贵30-50%，贵的是品控和研发。
三、采购避坑：别让6T含量骗了你
我见过太多采购，比价比到最后选了最便宜的三十的，然后做出来的制品耐热不够、SMT回流焊变形、客户退货，一次损失够买半年的好料。
PA6/6T采购这行，水比你想的深。三个坑必须绕开：
第一，看热变形温度和熔指不看牌号。同一个牌号不同批次性能可能波动，拿到料先测热变形温度和熔指，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PA66当PA6/6T卖，拿低6T含量当高含量卖。要COA、要6T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30块，做出来SMT连接器合格率90%；B料单价50块，合格率99%。算到每个连接器上，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——比如要阻燃又要耐高温、要增强又要耐电痕、要低成本又要SMT级——那不是PA6/6T的问题，是你需要的不是标准PA6/6T，是改性PA6/6T。
这时候可以看看宁波科隆新材目前在做的高性能改性PA6/6T方案，玻纤增强、阻燃、耐电痕、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PA6/6T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，PA6/6T行情一天一个样，对苯二甲酸、己二胺、玻纤、汇率都在动。
如果你需要巴斯夫、EMS、杜邦、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PA6/6T这事儿，三十的和七十的，差的不是四十。
单价是门槛，选对6T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SMT耐高温连接器的方案。把账算到每个连接器上，再加上合格率和退货损失，你才知道谁真便宜谁真贵。

How much is PA6/6T per kilogram?
PA6/6T is not one material: GF-reinforced, flame-retardant, and each carries a different price.

2. Why prices differ so much
Four factors: (1) composition — lower levels are cheaper; higher levels give better performance but cost more. (2) grade level — premium grades need special formulations and cost more. (3) functional modification — 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 heat deflection temperature and melt flow index 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 PA6/6T, you need a modified compound. Ningbo Kolong New Materials is developing high-performance modified PA6/6T solutions covering glass-fiber reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified PA6/6T 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; PA6/6T 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.
