PA610多少钱一公斤？
这个问题一搜，从十九块一公斤到七十块一公斤，报价差得比碳链长度还多。有人说我买的十九的国产纺丝级刷丝用得挺好，有人说我买的七十的杜邦RS 3061HSL才叫高端。到底差在哪？
说实话，问PA610多少钱一公斤的人，大概率还没搞懂PA610这东西不是一个料——通用级、玻纤增强级、食品级、高粘度级、纺丝级，每个分支价格都不一样。你拿纺丝级的价和玻纤增强比，那不叫比价，叫被忽悠。
PA610就是聚酰胺610，长碳链尼龙，比PA66吸水率低、尺寸稳定，常用于刷丝、汽车管路、精密齿轮、薄膜。
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，美国）
Zytel RS30G30HSL，玻纤增强级，参考价约52元/公斤。汽车、工业机械、结构件。
Zytel RS 3061HSL，无筋通用级，参考价约70元/公斤。通用注塑、精密齿轮。
Zytel RS32G10DO，玻纤增强级，参考价约50-70元/公斤。汽车、工业应用。
Zytel FE150065，通用级，参考价约50-70元/公斤。汽车部件、工业应用、日用品。
EMS（瑞士）
Grilamid 2S 20 natural，通用级，参考价约60-100元/公斤。汽车领域、通用注塑。
国产PA610（中企大厂）
国产国标PA610，参考价约51.2元/公斤。通用注塑、挤出、刷丝。
国产纺丝级刷丝，参考价约19元/公斤。工业刷丝、民用刷丝。
国产通用级，参考价约40-60元/公斤。性价比高，通用注塑、刷丝。
一句话总结：国产纺丝级19块，国产通用40-60块，进口通用50-70块，高端/玻纤增强60-100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PA610，价差凭什么这么大
PA610的价格差，主要藏在四个地方。
第一，粘度不同。低粘度适合注塑价格便宜，高粘度适合挤出和薄膜价格贵。高粘度PA610用于刷丝和薄膜。
第二，功能改性不同。玻纤增强、食品级、耐老化——这些都要加钱。玻纤增强比通用级贵20-30%。
第三，用途不同。通用级便宜，纺丝级适中，食品级/医疗级贵。特殊用途需要特殊认证。
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。同样是通用级，杜邦比国产贵20-40%，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十九的纺丝级，然后做出来的齿轮强度不够、尺寸不稳定、客户退货，一次损失够买半年的好料。
PA610采购这行，水比你想的深。三个坑必须绕开：
第一，看熔指和吸水率不看牌号。同一个牌号不同批次性能可能波动，拿到料先测熔指和吸水率，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PA610卖，拿低粘度当高粘度卖。要COA、要碳链检测、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19块，做出来刷丝次品率5%；B料单价50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——比如要阻燃又要低吸水、要增强又要耐水解、要低成本又要食品级——那不是PA610的问题，是你需要的不是标准PA610，是改性PA610。
这时候可以看看宁波科隆新材目前在做的高性能改性PA610方案，玻纤增强、阻燃、耐水解、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PA610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，PA610行情一天一个样，癸二胺、癸二酸、汇率都在动。
如果你需要杜邦、EMS、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PA610这事儿，十九的和七十的，差的不是五十一。
单价是门槛，选对粘度和性能才是底线。别让报价单上的数字迷惑了你——你买的不是一公斤塑料，是一公斤能做出低吸水制品的方案。把账算到每件制品上，再加上退货损失，你才知道谁真便宜谁真贵。

How much is PA610 per kilogram?
Quotes range from CNY 19/kg to CNY 70/kg. PA610 (polyamide 610) is a long-carbon-chain nylon with lower water absorption and better dimensional stability than PA66, not one material: general, GF-reinforced, food-grade, high-viscosity and fiber-spinning grades each carry a different price. Comparing a fiber-grade quote with a GF-reinforced one is not price comparison; it is how you get fooled.
PA610 is used in brush bristles, automotive tubing, precision gears and film.
1. Mainstream grade quotes (imported + domestic) — recent market references; live prices subject to same-day inquiry.
DuPont (USA)
Zytel RS30G30HSL, GF-reinforced grade, approx. CNY 52/kg. Automotive, industrial machinery, structural parts.
Zytel RS 3061HSL, unreinforced general grade, approx. CNY 70/kg. General injection, precision gears.
Zytel RS32G10DO, GF-reinforced, approx. CNY 50-70/kg. Automotive, industrial applications.
Zytel FE150065, general-purpose, approx. CNY 50-70/kg. Automotive parts, industrial applications, daily products.
EMS (Switzerland)
Grilamid 2S 20 natural, general-purpose, approx. CNY 60-100/kg. Automotive, general injection.
Domestic PA610 (Chinese majors)
Domestic national-standard PA610, approx. CNY 51.2/kg. General injection, extrusion, bristles.
Domestic fiber-spinning grade, approx. CNY 19/kg. Industrial and household bristles.
Domestic general-purpose, approx. CNY 40-60/kg. Cost-effective; general injection, bristles.
In short: domestic fiber CNY 19, domestic general CNY 40-60, imported general CNY 50-70, premium/GF CNY 60-100.
2. Why prices differ so much
Four factors: (1) Viscosity — low viscosity suits injection and is cheap; high viscosity suits extrusion and film and costs more (bristles and film need it). (2) Functional modification — GF reinforcement, food grade and aging resistance all add cost; GF costs 20-30% more than general. (3) Application — general is cheap, fiber mid-range, food/medical expensive. (4) Brand and origin — for the same general grade, DuPont costs 20-40% more than domestic, paying for quality control and R&D.
3. Procurement pitfalls
The cheapest fiber grade often gives gears with insufficient strength or dimensional instability, causing returns. Three traps to avoid:
First, test MFI and water absorption against the COA instead of trusting the grade name. Second, watch for substitution: some traders sell PA6 as PA610 or low-viscosity as high-viscosity; demand the COA, a carbon-chain test and original packaging. Third, calculate total cost: A at CNY 19/kg with a 5% defect rate vs. B at CNY 50/kg with 1% — B is cheaper per part.
4. Standard grades not enough? Consider modified compounds
If you need flame retardancy AND low water absorption, reinforcement AND hydrolysis resistance — you need modified PA610. Ningbo Kolong New Materials is developing high-performance modified PA610 grades covering GF reinforcement, flame retardancy, hydrolysis resistance and conductivity. Message us for a modified PA610 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
PA610 prices change daily — sebacic diamine, sebacic acid and exchange rates all move. Message us for same-day quotes on specific grades from DuPont, EMS or domestic producers; real numbers.
Final words
The gap between CNY 19 and CNY 70 is not CNY 51. Unit price is the threshold; choosing the right viscosity and performance is the baseline. You are buying a solution for making low-water-absorption parts. Do the math per part, add returns, and you will know who is truly cheap.
