PA66多少钱一公斤?价格差两倍,差的不是二十块
PA66多少钱一公斤?
这个问题一搜,从十八块一公斤到四十块一公斤,报价差得比玻纤含量还多。有人说我买的二十块的神马EPR27用得挺好,有人说我买的三十块的杜邦101L才叫真尼龙。到底差在哪?
说实话,问PA66多少钱一公斤的人,大概率还没搞懂PA66这东西不是一个料——纯树脂、玻纤增强、阻燃、耐磨、耐高温,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。
杜邦(DuPont)
101L,纯树脂通用级,参考价约28-30元/公斤。注塑级,高流动,机械零件、齿轮常用。
70G30L,30%玻纤增强,参考价约28-31元/公斤。高强度、尺寸稳定,汽车部件、电子连接器主力牌号。
巴斯夫(BASF)
A3EG3,15%玻纤增强,参考价约30-32元/公斤。Ultramid系列,热稳定、耐高温,电子电器常用。
A3WG6,30%玻纤增强,参考价约29-30元/公斤。高刚性、耐油,汽车结构件首选。
奥升德(Ascend,原首诺)
21SPC,纯树脂高刚性,参考价约15-23元/公斤。性价比之选,通用注塑、扎带、齿轮。
R515NT,15%玻纤增强,参考价约29元/公斤。增强级,外壳、汽车配件。
神马股份(中企大厂)
EPR27,有光中等粘度纯树脂,参考价约18-19元/公斤。国产主力牌号,质量稳定,价格比外企同级别低30%左右。
EPR27LS,纯树脂注塑级,参考价约36元/公斤。高流动、高光泽,汽车配件、电子外壳。
一句话总结:纯树脂18-25块,玻纤增强25-35块,阻燃/耐磨/特殊级35-50块。你要的是啥性能,决定了你该在哪一档选。
二、同是PA66,价差凭什么这么大
PA66的价格差,主要藏在四个地方。
第一,玻纤含量不同。纯树脂便宜,15%玻纤贵一点,30%玻纤更贵,40%以上玻纤最贵。玻纤加得越多,强度越高,价格也越高。
第二,功能改性不同。阻燃、耐磨、耐高温、耐水解——这些都要加钱。你买的不是纯尼龙,是加了料的尼龙方案。
第三,粘度和流动性。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。
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30%玻纤,杜邦比神马贵30%,贵的是品控和研发,不是智商税。
三、采购避坑:别让牌号骗了你
我见过太多采购,比价比到最后选了最便宜的十八块的,然后做出来的制品强度不够、尺寸不稳、客户退货,一次损失够买半年的好料。
PA66采购这行,水比你想的深。三个坑必须绕开:
第一,看玻纤含量不看牌号。同一个牌号不同批次玻纤含量可能波动,拿到料先测灰分,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PA66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18块,做出来次品率5%;B料单价25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、要增强又要耐磨、要耐高温又要低成本——那不是PA66的问题,是你需要的不是标准PA66,是改性PA66。
这时候可以看看宁波科隆新材目前在做的高性能改性PA66方案,玻纤增强、阻燃、耐磨、增韧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PA66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、己二胺、汇率都在动。
如果你需要杜邦、巴斯夫、奥升德、神马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PA66这事儿,十八的和四十的,差的不是二十二。
单价是门槛,选对牌号才是底线。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 PA66 per kilogram?
PA66 is not one material: flame-retardant, wear-resistant, high-temperature, and each carries a different price.
1. Mainstream grade quotes (imported + domestic) — recent market references; live prices subject to same-day inquiry.
DuPont
101L, approx. CNY 28-30/kg. injection; high-flow.
70G30L, approx. CNY 28-31/kg. high-strength; dimensional stability; automotive parts.
BASF
A3EG3, approx. CNY 30-32/kg. heat-stabilized; high-temperature.
A3WG6, approx. CNY 29-30/kg. high-rigidity; oil-resistant.
PA66
21SPC, approx. CNY 15-23/kg. general injection; gears.
R515NT, approx. CNY 29/kg. reinforced; automotive parts.
PA66
EPR27, approx. CNY 18-19/kg.
EPR27LS, approx. CNY 36/kg. high-flow; high-gloss; automotive parts.
2. Why prices differ so much
Four factors drive the price gap: composition or performance level, grade tier, application and brand/origin. Premium performance, special applications and imported brands all cost more; imports trade a premium for batch stability, while domestic grades offer better value.
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 PA66, you need a modified compound. Ningbo Kolong New Materials is developing high-performance modified PA66 solutions covering glass-fiber reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified PA66 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; PA66 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.
