PA9T多少钱一公斤？选型省钱，高温尼龙里的低调选手
PA9T多少钱一公斤？
这个问题一搜，从三十块一公斤到八十五块一公斤，报价差得比吸水率还多。有人说我买的三十块的可乐丽GR2300用得挺好，有人说我买的八十五块的可乐丽TA112才叫高反射。到底差在哪？
说实话，问PA9T多少钱一公斤的人，大概率还没搞懂PA9T这东西不是一个料——通用级、玻纤增强级、阻燃级、矿物填充级、纯树脂级，每个分支价格都不一样。你拿通用级的价和矿物填充级比，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。
可乐丽（Kuraray，日本）
Genestar GN2330，33%玻纤增强阻燃，参考价约30-55元/公斤。高流动、尺寸稳定，SMT连接器、电子配件。
Genestar GN2200，耐高温高刚度抗翘曲，参考价约36元/公斤。零件装置、结构件。
Genestar GR2300，玻纤增强电子电器，参考价约30元/公斤。电子电器、连接器。
Genestar TA112，矿物填充高反射率，参考价约85元/公斤。LED反射器、光学部件。
Genestar N1002A-M41，非增强纯树脂，参考价约78元/公斤。纯树脂、改性基料。
Genestar GN2450，电子电气汽车LED，参考价约80元/公斤。高端应用。
杜邦（DuPont，美国）
Zytel HTN系列PA9T，参考价约60-100元/公斤。高温尼龙，汽车、电子。
金发科技（中企大厂）
金发PA9T通用级，参考价约40-60元/公斤。国产主力，性价比高，电子连接器、汽车部件。
金发PA9T玻纤增强级，参考价约50-70元/公斤。结构件、耐高温部件。
一句话总结：通用级30-40块，玻纤增强30-55块，阻燃/耐高温50-70块，矿物填充/纯树脂70-90块，高端特殊80-100块。你要的是啥增强和功能，决定了你该在哪一档选。
二、同是PA9T，价差凭什么这么大
PA9T的价格差，主要藏在四个地方。
第一，玻纤含量不同。纯树脂贵，30%玻纤增强适中，45%以上玻纤更贵。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、抗翘曲、高反射、耐水解——这些都要加钱。矿物填充高反射级比通用级贵一倍。
第三，流动性不同。高流动适合薄壁精密注塑，加工窗口宽，价格也贵；通用流动价格适中。
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。同样是玻纤增强，可乐丽比金发贵30-50%，贵的是品控和研发。
三、采购避坑：别让吸水率骗了你
我见过太多采购，比价比到最后选了最便宜的三十块的，然后做出来的制品翘曲变形、尺寸不稳、客户退货，一次损失够买半年的好料。
PA9T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HDT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PA9T卖，拿通用级当阻燃级卖。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30块，做出来次品率5%；B料单价55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——比如要阻燃又要超高流动、要增强又要低翘曲、要耐高温又要低成本——那不是PA9T的问题，是你需要的不是标准PA9T，是改性PA9T。
这时候可以看看宁波科隆新材目前在做的高性能改性PA9T方案，玻纤增强、阻燃、低翘曲、高流动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PA9T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，PA9T行情一天一个样，原油、芳香族二酸、壬二胺、汇率都在动。
如果你需要可乐丽、杜邦、金发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PA9T这事儿，三十的和八十五的，差的不是五十五。
单价是门槛，选对增强含量和功能才是底线。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 PA9T per kilogram?
PA9T is not one material: GF-reinforced, flame-retardant, and each carries a different price.
1. Mainstream grade quotes (imported + domestic) — recent market references; live prices subject to same-day inquiry.

2. Why prices differ so much
Four factors: (1) glass-fiber content — lower levels are cheaper; higher levels give better performance but cost more. (2) functional modification — premium grades need special formulations and cost more. (3) flow — 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 PA9T, you need a modified compound. Ningbo Kolong New Materials is developing high-performance modified PA9T solutions covering glass-fiber reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified PA9T 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; PA9T 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.
