AES多少钱一公斤？
这个问题一搜，从十二块一公斤到二十八块一公斤，报价差得比耐候等级还多。有人说我买的十二的国产通用用得挺好，有人说我买的二十八的韩国锦湖高端才叫耐候。到底差在哪？
说实话，问AES多少钱一公斤的人，大概率还没搞懂AES这东西不是一个料——通用级、耐候级、高抗冲级、耐热级、电镀级，每个分支价格都不一样。你拿通用级的价和耐候级比，那不叫比价，叫被忽悠。
AES就是丙烯腈-EPDM-苯乙烯共聚物，耐候性优于ABS，常用于汽车外饰、户外电子、家电外壳、建筑材料、电动工具。
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。
韩国锦湖（Kumho，韩国）
AES通用级，参考价约18-28元/公斤。汽车外饰、户外电子、家电外壳。
AES耐候级，参考价约20-28元/公斤。户外应用、汽车外饰、建筑材料。
AES高抗冲级，参考价约19-27元/公斤。汽车外饰、家电外壳、结构件。
国产AES（中企大厂）
通用级，参考价约12-20元/公斤。性价比高，通用注塑、汽车、电子。
耐候级，参考价约14-22元/公斤。户外应用、汽车外饰、建筑材料。
高抗冲级，参考价约13-21元/公斤。汽车外饰、家电外壳、结构件。
一句话总结：国产通用12-20块，国产耐候/高抗冲13-22块，进口通用18-28块，进口耐候/高抗冲19-28块。你要的是啥耐候等级和性能，决定了你该在哪一档选。
二、同是AES，价差凭什么这么大
AES的价格差，主要藏在四个地方。
第一，EPDM含量不同。EPDM含量15%左右便宜，含量30%以上耐候好但贵。EPDM含量越高，耐候性和抗冲击性越好，但耐热性略降。
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UV稳定剂，价格更高。
第三，耐热等级不同。通用级耐热80度左右价格便宜，高耐热级耐热100度以上价格贵。耐热等级决定使用环境。
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。同样是耐候级，韩国锦湖比国产贵30-50%，贵的是品控和研发。
三、采购避坑：别让耐候等级骗了你
我见过太多采购，比价比到最后选了最便宜的十二的，然后做出来的户外制品耐候差、变色、客户退货，一次损失够买半年的好料。
AES采购这行，水比你想的深。三个坑必须绕开：
第一，看耐候等级和冲击强度不看牌号。同一个牌号不同批次性能可能波动，拿到料先测耐候等级和冲击强度，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ABS当AES卖，拿低EPDM含量当高含量卖。要COA、要EPDM含量检测、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12块，做出来户外制品次品率5%；B料单价20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——比如要耐候又要高耐热、要高抗冲又要高流动、要低成本又要电镀级——那不是AES的问题，是你需要的不是标准AES，是改性AES。
这时候可以看看宁波科隆新材目前在做的高性能改性AES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AES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，AES行情一天一个样，丙烯腈、EPDM、苯乙烯、UV稳定剂、汇率都在动。
如果你需要韩国锦湖、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AES这事儿，十二的和二十八的，差的不是十六。
单价是门槛，选对耐候等级和性能才是底线。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 AES per kilogram?
A quick search shows quotes ranging from CNY 12/kg to CNY 28/kg — a spread wider than the weatherability grade itself. Some buyers say the CNY 12 domestic general-purpose grade works fine; others insist only the CNY 28 Korean Kumho premium grade counts as weather-resistant. Where does the difference really lie?
Honestly, anyone asking "how much is AES per kilo" probably has not yet understood that AES is not a single material — general-purpose, weather-resistant, high-impact, heat-resistant and plating grades each carry a different price. Comparing a general-purpose quote with a weather-resistant one is not price comparison; it is how you get fooled.
AES is an acrylonitrile-EPDM-styrene copolymer with better weatherability than ABS. It is commonly used in automotive exteriors, outdoor electronics, appliance housings, building materials and power tools.
1. Mainstream grade quotes (imported + domestic)
Here are the high-volume grades and reference prices on the market. Figures below are recent market references; live prices are subject to same-day inquiry.
Kumho (South Korea)
AES general-purpose grade, approx. CNY 18-28/kg. Automotive exteriors, outdoor electronics, appliance housings.
AES weather-resistant grade, approx. CNY 20-28/kg. Outdoor applications, automotive exteriors, building materials.
AES high-impact grade, approx. CNY 19-27/kg. Automotive exteriors, appliance housings, structural parts.
Domestic AES (Chinese majors)
General-purpose grade, approx. CNY 12-20/kg. Cost-effective; general injection molding, automotive, electronics.
Weather-resistant grade, approx. CNY 14-22/kg. Outdoor applications, automotive exteriors, building materials.
High-impact grade, approx. CNY 13-21/kg. Automotive exteriors, appliance housings, structural parts.
In short: domestic general-purpose CNY 12-20, domestic weather-resistant/high-impact CNY 13-22, imported general-purpose CNY 18-28, imported weather-resistant/high-impact CNY 19-28. The weatherability grade and performance you need decide which tier you belong in.
2. Why do AES prices differ so much
The AES price gap mainly hides in four factors.
First, EPDM content. Around 15% EPDM is cheap; above 30% gives good weatherability but costs more. The higher the EPDM content, the better the weatherability and impact resistance, but heat resistance drops slightly.
Second, weatherability grade. General-purpose is cheap; high-weather-resistance is expensive. High weatherability needs special UV stabilizers and costs more.
Third, heat resistance grade. General-purpose grades with HDT around 80°C are cheap; high-heat grades with HDT above 100°C cost more. Heat resistance level determines the service environment.
Fourth, brand and origin. Imports carry a premium but offer batch stability; domestic grades offer value but fewer options. For the same weather-resistant grade, Kumho costs 30-50% more than domestic — you pay for quality control and R&D.
3. Procurement pitfalls: don't let the weatherability grade fool you
I have seen too many buyers end up choosing the cheapest CNY 12 material after endless price comparison, only to have outdoor parts fade and change color, trigger customer returns — one loss enough to buy half a year of good material.
Procurement of AES is deeper water than you think. Three traps must be avoided:
First, test weatherability grade and impact strength instead of trusting the grade name. Performance of the same grade can fluctuate between batches. Test against the COA before use. Don't listen to salespeople saying "close enough" — close enough is far apart.
Second, watch out for substitution fraud. Some traders sell ABS as AES, or low-EPDM as high-EPDM. Demand the COA, an EPDM-content test and original packaging. Only accept material with all three.
Third, don't compare unit price alone — calculate total cost. Material A at CNY 12/kg yields a 5% defect rate on outdoor parts; material B at CNY 20/kg yields 1%. Per finished part, B is actually cheaper.
4. Standard grades not enough? Consider modified compounds
If standard grades always fall short — you need weatherability AND high heat resistance, high impact AND high flow, or low cost AND a plating grade — the problem is not AES itself; you don't need standard AES, you need modified AES.
Ningbo Kolong New Materials is developing high-performance modified AES solutions, with grades covering glass-fiber reinforcement, flame retardancy, weather resistance and conductivity. For special needs, message us for a modified AES quote reference — it saves not only money but also trial-and-error time compared with buying base resin and tuning additives yourself.
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. AES prices change daily — acrylonitrile, EPDM, styrene, UV stabilizers and exchange rates all move.
If you need same-day quotes for specific grades from Kumho or domestic producers, message us and we will send a live price sheet. No beating around the bush — real numbers.
Final words
For AES, the difference between CNY 12 and CNY 28 is not CNY 16.
Unit price is the threshold; choosing the right weatherability grade and performance is the baseline. Don't let the quote sheet fool you — you are not buying one kilogram of plastic, you are buying a solution for making weather-resistant automotive exterior parts. Do the math per finished part, add in the loss from rejected goods, and you will know who is truly cheap and who is truly expensive.
