ASA/PMMA多少钱一公斤？
这个问题一搜，从十六块一公斤到三十八块一公斤，报价差得比ASA比例还多。有人说我买的十六的国产通用用得挺好，有人说我买的三十八的进口高光泽才叫高端。到底差在哪？
说实话，问ASA/PMMA多少钱一公斤的人，大概率还没搞懂ASA/PMMA这东西不是一个料——通用级、高光泽级、耐候级、耐热级、电镀级，每个分支价格都不一样。你拿通用级的价和高光泽比，那不叫比价，叫被忽悠。
ASA/PMMA就是丙烯腈苯乙烯丙烯酸酯/聚甲基丙烯酸甲酯合金，结合了ASA的耐候和PMMA的高光泽，常用于汽车外饰、户外电子、家电外壳、卫浴用品、建筑材料。
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ASA/PMMA（外企大厂）
通用级，参考价约22-32元/公斤。汽车外饰、户外电子、家电外壳。
高光泽级，参考价约24-35元/公斤。汽车外饰、卫浴用品、高端家电。
耐候级，参考价约25-38元/公斤。户外应用、汽车外饰、建筑材料。
国产ASA/PMMA（中企大厂）
通用级，参考价约16-26元/公斤。性价比高，汽车外饰、户外电子、家电外壳。
高光泽级，参考价约18-29元/公斤。汽车外饰、卫浴用品、高端家电。
耐候级，参考价约19-30元/公斤。户外应用、汽车外饰、建筑材料。
一句话总结：国产通用16-26块，国产高光泽/耐候18-30块，进口通用22-32块，进口高光泽/耐候24-38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ASA/PMMA，价差凭什么这么大
ASA/PMMA的价格差，主要藏在四个地方。
第一，ASA比例不同。ASA比例30%左右便宜，比例60%以上高耐候但贵。ASA比例越高，耐候性越好，但光泽度略降。
第二，光泽等级不同。通用级便宜，高光泽级贵。高光泽需要特殊工艺，价格更高。
第三，耐候等级不同。通用级便宜，耐候级贵。耐候需要特殊UV稳定剂，价格更高。
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。同样是高光泽级，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十六的，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。
ASA/PMMA采购这行，水比你想的深。三个坑必须绕开：
第一，看耐候等级和光泽度不看牌号。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光泽度，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/PMMA当ASA/PMMA卖，拿低ASA比例当高比例卖。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16块，做出来制品次品率5%；B料单价26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——比如要高光泽又要耐候、要耐热又要高流动、要低成本又要电镀级——那不是ASA/PMMA的问题，是你需要的不是标准ASA/PMMA，是改性ASA/PMMA。
这时候可以看看宁波科隆新材目前在做的高性能改性ASA/PMMA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ASA/PMMA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，ASA/PMMA行情一天一个样，丙烯腈、苯乙烯、丙烯酸酯、甲基丙烯酸甲酯、UV稳定剂、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ASA/PMMA这事儿，十六的和三十八的，差的不是二十二。
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，是一公斤能做出高光泽汽车外饰的方案。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 ASA/PMMA per kilogram?
A quick search shows quotes ranging from CNY 16/kg to CNY 38/kg — a spread wider than the ASA ratio itself. Some buyers say the CNY 16 domestic general-purpose grade works fine; others insist only the CNY 38 imported high-gloss grade counts as premium. Where does the difference really lie?
Honestly, anyone asking "how much is ASA/PMMA per kilo" probably has not yet understood that ASA/PMMA is not a single material — general-purpose, high-gloss, weather-resistant, heat-resistant and plating grades each carry a different price. Comparing a general-purpose quote with a high-gloss one is not price comparison; it is how you get fooled.
ASA/PMMA is an acrylonitrile-styrene-acrylate/polymethyl methacrylate alloy that combines ASA's weatherability with PMMA's high gloss. It is commonly used in automotive exteriors, outdoor electronics, appliance housings, sanitary ware and building materials.
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.
Imported ASA/PMMA (overseas majors)
General-purpose grade, approx. CNY 22-32/kg. Automotive exteriors, outdoor electronics, appliance housings.
High-gloss grade, approx. CNY 24-35/kg. Automotive exteriors, sanitary ware, premium appliances.
Weather-resistant grade, approx. CNY 25-38/kg. Outdoor applications, automotive exteriors, building materials.
Domestic ASA/PMMA (Chinese majors)
General-purpose grade, approx. CNY 16-26/kg. Cost-effective; automotive exteriors, outdoor electronics, appliance housings.
High-gloss grade, approx. CNY 18-29/kg. Automotive exteriors, sanitary ware, premium appliances.
Weather-resistant grade, approx. CNY 19-30/kg. Outdoor applications, automotive exteriors, building materials.
In short: domestic general-purpose CNY 16-26, domestic high-gloss/weather-resistant CNY 18-30, imported general-purpose CNY 22-32, imported high-gloss/weather-resistant CNY 24-38. The ASA ratio and performance you need decide which tier you belong in.
2. Why do ASA/PMMA prices differ so much
The ASA/PMMA price gap mainly hides in four factors.
First, ASA ratio. Around 30% ASA is cheap; above 60% gives high weatherability but costs more. The higher the ASA content, the better the weatherability, but gloss drops slightly.
Second, gloss grade. General-purpose is cheap; high-gloss is expensive. High gloss needs special processing and costs more.
Third, weatherability grade. General-purpose is cheap; weather-resistant is expensive. Weather resistance needs special UV stabilizers and costs more.
Fourth, brand and origin. Imports carry a premium but offer batch stability; domestic grades offer value but fewer options. For the same high-gloss grade, imported costs 30-50% more than domestic — you pay for quality control and R&D.
3. Procurement pitfalls: don't let the ASA ratio fool you
I have seen too many buyers end up choosing the cheapest CNY 16 material after endless price comparison, only to have parts fail on weatherability and change color, trigger customer returns — one loss enough to buy half a year of good material.
Procurement of ASA/PMMA is deeper water than you think. Three traps must be avoided:
First, test weatherability grade and gloss 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/PMMA as ASA/PMMA, or low-ASA as high-ASA. Demand the COA, an ASA-ratio test and original packaging. Only accept material with all three.
Third, don't compare unit price alone — calculate total cost. Material A at CNY 16/kg yields a 5% defect rate; material B at CNY 26/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 high gloss AND weatherability, heat resistance AND high flow, or low cost AND a plating grade — the problem is not ASA/PMMA itself; you don't need standard ASA/PMMA, you need modified ASA/PMMA.
Ningbo Kolong New Materials is developing high-performance modified ASA/PMMA solutions, with grades covering glass-fiber reinforcement, flame retardancy, weather resistance and conductivity. For special needs, message us for a modified ASA/PMMA 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. ASA/PMMA prices change daily — acrylonitrile, styrene, acrylate, methyl methacrylate, UV stabilizers and exchange rates all move.
If you need same-day quotes for specific imported or domestic grades, message us and we will send a live price sheet. No beating around the bush — real numbers.
Final words
For ASA/PMMA, the difference between CNY 16 and CNY 38 is not CNY 22.
Unit price is the threshold; choosing the right ASA ratio 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 high-gloss 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.
