PA6多少钱一公斤？主流牌号价格对照表
PA6多少钱一公斤？
这个问题一搜，从十块一公斤到三十五块一公斤，报价差得比粘度还多。有人说我买的十二块的巴陵石化用得挺好，有人说我买的二十块的巴斯夫B3S才叫稳定。到底差在哪？
说实话，问PA6多少钱一公斤的人，大概率还没搞懂PA6这东西比PA66家族更庞大——纯树脂、玻纤增强、阻燃、透明、增韧，每个分支价格都不一样。你拿纯树脂的价和玻纤增强比，那不叫比价，叫被忽悠。
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）
B3S，纯树脂高流动，参考价约17-18元/公斤。Ultramid系列，耐油、易加工，通用注塑、薄壁制品。
B3EG6，30%玻纤增强，参考价约17-18元/公斤。高强度、热稳定，电子电器、汽车部件。
B3WG7，35%玻纤增强，参考价约35元/公斤。高刚性、耐高温老化，结构件首选。
朗盛（Lanxess）
B30S，纯树脂通用级，参考价约27-28元/公斤。Durethan系列，中等粘度，注塑挤出通用。
BKV30H2.0，30%玻纤增强热稳定，参考价约15-16元/公斤。性价比高，汽车、电子常用。
宇部兴产（UBE）
1013B，纯树脂中粘度，参考价约20-21元/公斤。日本宇部主力牌号，质量稳定，注塑级通用。
巴陵石化（中企大厂）
BL3200，纯树脂注塑级，参考价约12-15元/公斤。国产主力，高流动，通用制品、扎带、齿轮。
BL3240H，纯树脂高粘度，参考价约13-16元/公斤。挤出级，管材、型材、单丝。
一句话总结：纯树脂12-20块，玻纤增强15-25块，阻燃/耐磨/特殊级25-40块。你要的是啥性能，决定了你该在哪一档选。
二、同是PA6，价差凭什么这么大
PA6的价格差，主要藏在四个地方。
第一，粘度不同。低粘度（高流动）适合薄壁注塑，加工效率高，价格也贵；高粘度适合挤出，价格相对低。粘度是PA6的核心指标，选错了全白搭。
第二，玻纤含量不同。纯树脂便宜，15%玻纤贵一点，30%玻纤更贵。玻纤加得越多，强度越高，价格也越高。
第三，功能改性不同。阻燃、耐磨、增韧、透明——这些都要加钱。你买的不是纯尼龙，是加了料的尼龙方案。
第四，品牌和产地。进口溢价高但批次稳定，国产性价比高但质量参差。同样是纯树脂，巴斯夫比巴陵贵30%，贵的是品控和研发。
三、采购避坑：别让粘度骗了你
我见过太多采购，比价比到最后选了最便宜的十二块的，然后做出来的制品流动不够、充模不满、客户退货，一次损失够买半年的好料。
PA6采购这行，水比你想的深。三个坑必须绕开：
第一，看粘度不看牌号。同一个牌号不同批次粘度可能波动，拿到料先测熔指，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。有些贸易商拿回料当新料卖，拿纯树脂当增强级卖。要COA、要物性报告、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12块，做出来次品率5%；B料单价18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——比如要阻燃又要高流动、要增强又要增韧、要透明又要耐高温——那不是PA6的问题，是你需要的不是标准PA6，是改性PA6。
这时候可以看看宁波科隆新材目前在做的高性能改性PA6方案，玻纤增强、阻燃、增韧、耐磨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，尼龙行情一天一个样，原油、己内酰胺、汇率都在动。
如果你需要巴斯夫、朗盛、宇部、巴陵石化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这事儿，十二的和三十五的，差的不是二十三。
单价是门槛，选对粘度和牌号才是底线。别让报价单上的数字迷惑了你——你买的不是一公斤塑料，是一公斤能做出合格制品的方案。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 PA6 per kilogram?
PA6 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.
BASF
B3S, approx. CNY 17-18/kg. oil-resistant; easy processing; general injection; thin-wall parts.
B3EG6, approx. CNY 17-18/kg. high-strength; heat-stabilized; electronics; automotive parts.
B3WG7, approx. CNY 35/kg. high-rigidity.
PA6
B30S, approx. CNY 27-28/kg. injection extrusion general.
approx. CNY 15-16/kg. automotive.
PA6
1013B, approx. CNY 20-21/kg. injection general.

BL3240H, approx. CNY 13-16/kg. extrusion; pipe; profiles.
2. Why prices differ so much
Four factors: (1) viscosity — lower levels are cheaper; higher levels give better performance but cost more. (2) glass-fiber content — 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 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 PA6, you need a modified compound. Ningbo Kolong New Materials is developing high-performance modified PA6 solutions covering glass-fiber reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified PA6 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 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.
