PA6T多少钱一公斤？
这个问题一搜，从二十八块一公斤到七十九块一公斤，报价差得比耐热等级还多。有人说我买的二十八块的三井化学A335用得挺好，有人说我买的七十九的杜邦HTN51G35HSL才叫耐高温。到底差在哪？
说实话，问PA6T多少钱一公斤的人，大概率还没搞懂PA6T这东西不是一个料——通用级、玻纤增强级、阻燃级、耐高温级、耐化学级，每个分支价格都不一样。你拿通用级的价和耐高温级比，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。
三井化学（Mitsui，日本）
ARLEN A335，注塑级，参考价约28-35元/公斤。电子电器、汽车部件、家用。
ARLEN A350，通用级，参考价约30-38元/公斤。通用注塑、结构件。
ARLEN C215，高流动级，参考价约35-45元/公斤。薄壁制品、电子连接器。
ARLEN E430N，30%玻纤增强阻燃V0，参考价约65元/公斤。高熔点耐高温，电子电器。
ARLEN E630NK，耐高温耐化学，参考价约42-50元/公斤。电子电器部件、家电。
杜邦（DuPont，美国）
Zytel HTN FR52G30BL，30%玻纤阻燃，参考价约30-40元/公斤。电子电器、阻燃部件。
Zytel HTN51G35HSL，35%玻纤耐高温，参考价约79元/公斤。耐高温原料、汽车部件。
Zytel HTN FR55G50NHLW，50%玻纤无卤阻燃，参考价约50-70元/公斤。高端电子、汽车。
Zytel HTN FR52G20LX，20%玻纤阻燃，参考价约28元/公斤。通用阻燃、电子部件。
金发科技（中企大厂）
金发PA6T通用级，参考价约30-45元/公斤。国产主力，性价比高，电子连接器、汽车部件。
金发PA6T玻纤增强级，参考价约40-60元/公斤。结构件、耐高温部件。
一句话总结：通用级28-38块，玻纤增强35-50块，阻燃级30-50块，耐高温/高端50-80块。你要的是啥增强和耐热，决定了你该在哪一档选。
二、同是PA6T，价差凭什么这么大
PA6T的价格差，主要藏在四个地方。
第一，玻纤含量不同。纯树脂适中，20%玻纤增强便宜，30%玻纤适中，50%玻纤贵。玻纤加得越多，强度越高，价格也越高。
第二，耐热等级不同。通用级耐热260℃左右便宜，耐高温级耐热290℃以上贵。耐热是PA6T的核心指标，每升一档价格都要加。
第三，阻燃性能不同。普通级不阻燃价格便宜，阻燃V0级价格贵。电子电器用PA6T必须阻燃。
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%玻纤阻燃，三井比金发贵30-50%，贵的是品控和研发。
三、采购避坑：别让耐热骗了你
我见过太多采购，比价比到最后选了最便宜的二十八块的，然后做出来的制品SMT过炉变形、客户退货，一次损失够买半年的好料。
PA6T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PA6T卖，拿低耐热当高耐热卖。要COA、要耐热测试报告、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28块，做出来SMT过炉变形率5%；B料单价65块，变形率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、要增强又要低翘曲、要耐高温又要低成本——那不是PA6T的问题，是你需要的不是标准PA6T，是改性PA6T。
这时候可以看看宁波科隆新材目前在做的高性能改性PA6T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PA6T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，PA6T行情一天一个样，对苯二甲酸、己二胺、汇率都在动。
如果你需要三井化学、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PA6T这事儿，二十八的和七十九的，差的不是五十一。
单价是门槛，选对耐热等级和玻纤含量才是底线。别让报价单上的数字迷惑了你——你买的不是一公斤塑料，是一公斤能过SMT回流焊的方案。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。

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) heat grade — premium grades need special formulations and cost more. (3) application — 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 PA6T, you need a modified compound. Ningbo Kolong New Materials is developing high-performance modified PA6T solutions covering glass-fiber reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified PA6T 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; PA6T 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.
