PA6/ASA多少钱一公斤？
这个问题一搜，从十八块一公斤到四十五块一公斤，报价差得比ASA比例还多。有人说我买的十八的国产通用用得挺好，有人说我买的四十五的进口高耐候才叫高端。到底差在哪？
说实话，问PA6/ASA多少钱一公斤的人，大概率还没搞懂PA6/ASA这东西不是一个料——通用级、高耐候级、高抗冲级、耐热级、阻燃级，每个分支价格都不一样。你拿通用级的价和高耐候比，那不叫比价，叫被忽悠。
PA6/ASA就是尼龙6/丙烯腈苯乙烯丙烯酸酯合金，结合了PA6的高强度和ASA的高耐候，常用于汽车外饰、电子电器、工业机械、户外用品、结构件。
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PA6/ASA（外企大厂）
通用级，参考价约25-35元/公斤。汽车外饰、电子电器、工业机械。
高耐候级，参考价约30-42元/公斤。户外用品、汽车外饰、特殊应用。
高抗冲级，参考价约32-45元/公斤。汽车配件、结构件、电动工具。
国产PA6/ASA（中企大厂）
通用级，参考价约18-28元/公斤。性价比高，汽车外饰、电子电器、工业机械。
高耐候级，参考价约22-34元/公斤。户外用品、汽车外饰、特殊应用。
玻纤增强级，参考价约20-32元/公斤。结构件、汽车、工业机械。
一句话总结：国产通用18-28块，国产高耐候/玻纤增强20-34块，进口通用25-35块，进口高耐候/高抗冲30-45块。你要的是啥ASA比例和性能，决定了你该在哪一档选。
二、同是PA6/ASA，价差凭什么这么大
PA6/ASA的价格差，主要藏在四个地方。
第一，ASA比例不同。低ASA便宜，高ASA贵。ASA比例越高，耐候性和抗冲性越好，但价格更高。
第二，耐候等级不同。通用级便宜，高耐候级贵。高耐候需要特殊ASA含量，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20-40%。
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。同样是高耐候级，进口比国产贵30-50%，贵的是品控和研发。
三、采购避坑：别让ASA比例骗了你
我见过太多采购，比价比到最后选了最便宜的十八的，然后做出来的制品耐候差、变色、客户退货，一次损失够买半年的好料。
PA6/ASA采购这行，水比你想的深。三个坑必须绕开：
第一，看耐候性和冲击强度不看牌号。同一个牌号不同批次性能可能波动，拿到料先测耐候性和冲击强度，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PA6/ASA卖，拿低ASA当高ASA卖。要COA、要ASA比例检测、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18块，做出来制品次品率5%；B料单价28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——比如要高耐候又要高抗冲、要耐热又要高流动、要低成本又要阻燃级——那不是PA6/ASA的问题，是你需要的不是标准PA6/ASA，是改性PA6/ASA。
这时候可以看看宁波科隆新材目前在做的高性能改性PA6/ASA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PA6/ASA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，PA6/ASA行情一天一个样，己内酰胺、丙烯腈、苯乙烯、丙烯酸酯、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PA6/ASA这事儿，十八的和四十五的，差的不是二十七。
单价是门槛，选对ASA比例和性能才是底线。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候汽车外饰的方案。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 PA6/ASA per kilogram?
Quotes range from CNY 18/kg to CNY 45/kg. PA6/ASA (nylon 6/ASA alloy) is not one material: general, high-weatherability, high-impact, heat-resistant and flame-retardant grades each carry a different price.
The alloy combines PA6's high strength with ASA's high weatherability, and is used in automotive exteriors, electronics, industrial machinery, outdoor products and structural parts.
1. Mainstream grade quotes (imported + domestic) — recent market references; live prices subject to same-day inquiry.
Imported PA6/ASA (overseas majors)
General-purpose, approx. CNY 25-35/kg. Automotive exteriors, electronics, industrial machinery.
High-weatherability, approx. CNY 30-42/kg. Outdoor products, automotive exteriors, special applications.
High-impact, approx. CNY 32-45/kg. Automotive parts, structural parts, power tools.
Domestic PA6/ASA (Chinese majors)
General-purpose, approx. CNY 18-28/kg. Cost-effective; automotive exteriors, electronics, industrial machinery.
High-weatherability, approx. CNY 22-34/kg. Outdoor products, automotive exteriors, special applications.
GF-reinforced, approx. CNY 20-32/kg. Structural parts, automotive, industrial machinery.
In short: domestic general CNY 18-28, domestic high-weatherability/GF CNY 20-34, imported general CNY 25-35, imported high-weatherability/high-impact CNY 30-45.
2. Why prices differ so much
Four factors: (1) ASA ratio — higher ASA gives better weatherability and impact but costs more. (2) Weatherability grade — high grades need special ASA content. (3) Reinforcement — GF costs 20-40% 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 weatherability or discolors, causing returns. Three traps to avoid:
First, test weatherability and impact strength against the COA instead of trusting the grade name. Second, watch for substitution: some traders sell PA6 as PA6/ASA or low-ASA as high-ASA; demand the COA, an ASA-ratio test and original packaging. Third, calculate total cost: A at CNY 18/kg with a 5% defect rate vs. B at CNY 28/kg with 1% — B is cheaper per part.
4. Standard grades not enough? Consider modified compounds
If you need high weatherability AND high impact, heat resistance AND high flow — you need modified PA6/ASA. Ningbo Kolong New Materials is developing high-performance modified PA6/ASA grades covering GF reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified PA6/ASA 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
PA6/ASA prices change daily — caprolactam, acrylonitrile, styrene, acrylate, glass fiber, flame retardants and exchange rates all move. Message us for same-day quotes; real numbers.
Final words
The gap between CNY 18 and CNY 45 is not CNY 27. Unit price is the threshold; choosing the right ASA ratio and performance is the baseline. You are buying a solution for making high-weatherability automotive exteriors. Do the math per part, add rejected-goods loss, and you will know who is truly cheap.
