PA1012多少钱一公斤？
这个问题一搜，从二十八块一公斤到七十块一公斤，报价差得比碳链长度还多。有人说我买的二十八的国产通用用得挺好，有人说我买的七十的进口高耐磨才叫高端。到底差在哪？
说实话，问PA1012多少钱一公斤的人，大概率还没搞懂PA1012这东西不是一个料——通用级、高耐磨级、低吸水级、玻纤增强级、阻燃级，每个分支价格都不一样。你拿通用级的价和高耐磨比，那不叫比价，叫被忽悠。
PA1012就是尼龙1012，由癸二胺和十二碳二酸缩聚制得，长碳链尼龙，低吸水、高耐磨、耐化学，常用于汽车配件、电子电器、工业机械、耐磨件、油管。
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PA1012（外企大厂）
通用级，参考价约40-55元/公斤。汽车配件、电子电器、工业机械。
高耐磨级，参考价约50-65元/公斤。耐磨件、齿轮、轴承、滑块。
玻纤增强级，参考价约55-70元/公斤。结构件、汽车、工业机械。
国产PA1012（中企大厂）
通用级，参考价约28-42元/公斤。性价比高，汽车配件、电子电器、工业机械。
高耐磨级，参考价约35-52元/公斤。耐磨件、齿轮、轴承、滑块。
玻纤增强级，参考价约40-58元/公斤。结构件、汽车、工业机械。
一句话总结：国产通用28-42块，国产高耐磨/玻纤增强35-58块，进口通用40-55块，进口高耐磨/玻纤增强50-70块。你要的是啥碳链长度和性能，决定了你该在哪一档选。
二、同是PA1012，价差凭什么这么大
PA1012的价格差，主要藏在四个地方。
第一，碳链长度不同。短碳链便宜，长碳链贵。碳链越长，低吸水性和耐磨性越好，但价格更高。
第二，耐磨等级不同。通用级便宜，高耐磨级贵。高耐磨需要特殊配方，价格更高。
第三，增强方式不同。无筋通用便宜，玻纤增强贵。玻纤增强比无筋通用贵30-50%。
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。同样是高耐磨级，进口比国产贵30-50%，贵的是品控和研发。
三、采购避坑：别让碳链长度骗了你
我见过太多采购，比价比到最后选了最便宜的二十八的，然后做出来的制品耐磨差、吸水大、客户退货，一次损失够买半年的好料。
PA1012采购这行，水比你想的深。三个坑必须绕开：
第一，看吸水率和磨耗量不看牌号。同一个牌号不同批次性能可能波动，拿到料先测吸水率和磨耗量，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PA12当PA1012卖，拿短碳链当长碳链卖。要COA、要碳链长度检测、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28块，做出来制品次品率5%；B料单价42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——比如要高耐磨又要高强度、要低吸水又要高流动、要低成本又要阻燃级——那不是PA1012的问题，是你需要的不是标准PA1012，是改性PA1012。
这时候可以看看宁波科隆新材目前在做的高性能改性PA1012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PA1012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，PA1012行情一天一个样，癸二胺、十二碳二酸、催化剂、玻纤、阻燃剂、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PA1012这事儿，二十八的和七十的，差的不是四十二。
单价是门槛，选对碳链长度和性能才是底线。别让报价单上的数字迷惑了你——你买的不是一公斤塑料，是一公斤能做出高耐磨齿轮的方案。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 PA1012 per kilogram?
Quotes range from CNY 28/kg to CNY 70/kg. PA1012 (nylon 1012, made by polycondensation of sebacic diamine and dodecanedioic acid) is a long-carbon-chain nylon, not one material: general, high-wear, low-water-absorption, glass-fiber-reinforced and flame-retardant grades each carry a different price.
PA1012 offers low water absorption, high wear resistance and chemical resistance, and is used in automotive parts, electronics, industrial machinery, wear parts and oil lines.
1. Mainstream grade quotes (imported + domestic) — recent market references; live prices subject to same-day inquiry.
Imported PA1012 (overseas majors)
General-purpose, approx. CNY 40-55/kg. Automotive parts, electronics, industrial machinery.
High-wear, approx. CNY 50-65/kg. Wear parts, gears, bearings, sliders.
GF-reinforced, approx. CNY 55-70/kg. Structural parts, automotive, industrial machinery.
Domestic PA1012 (Chinese majors)
General-purpose, approx. CNY 28-42/kg. Cost-effective; automotive parts, electronics, industrial machinery.
High-wear, approx. CNY 35-52/kg. Wear parts, gears, bearings, sliders.
GF-reinforced, approx. CNY 40-58/kg. Structural parts, automotive, industrial machinery.
In short: domestic general CNY 28-42, domestic high-wear/GF CNY 35-58, imported general CNY 40-55, imported high-wear/GF CNY 50-70.
2. Why prices differ so much
Four factors: (1) Carbon-chain length — longer chains give better low water absorption and wear resistance but cost more. (2) Wear grade — high-wear grades need special formulations. (3) Reinforcement — GF costs 30-50% more than unreinforced. (4) Brand and origin — imports cost 30-50% more for the same grade, paying for quality control and R&D.
3. Procurement pitfalls
The cheapest material often fails on wear resistance or absorbs too much water, causing returns. Three traps to avoid:
First, test water absorption and abrasion loss against the COA instead of trusting the grade name. Second, watch for substitution: some traders sell PA12 as PA1012 or short-chain as long-chain; demand the COA, a carbon-chain-length test and original packaging. Third, calculate total cost: A at CNY 28/kg with a 5% defect rate vs. B at CNY 42/kg with 1% — B is cheaper per part.
4. Standard grades not enough? Consider modified compounds
If you need high wear AND high strength, low water absorption AND high flow — you need modified PA1012. Ningbo Kolong New Materials is developing high-performance modified PA1012 grades covering GF reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified PA1012 quote reference.
In plain terms: standard grades are a big pot of shared rice; modified compounds are a dish cooked to order.
5. Same-day quotes via message
PA1012 prices change daily — sebacic diamine, dodecanedioic acid, catalysts, glass fiber, flame retardants and exchange rates all move. Message us for same-day quotes; real numbers.
Final words
The gap between CNY 28 and CNY 70 is not CNY 42. Unit price is the threshold; choosing the right carbon-chain length and performance is the baseline. You are buying a solution for making high-wear gears. Do the math per part, add rejected-goods loss, and you will know who is truly cheap.
