PMMA/ASA多少钱一公斤？
这个问题一搜，从十五块一公斤到三十五块一公斤，报价差得比PMMA比例还多。有人说我买的十五的国产通用用得挺好，有人说我买的三十五的进口高端才叫高光泽耐候。到底差在哪？
说实话，问PMMA/ASA多少钱一公斤的人，大概率还没搞懂PMMA/ASA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。
PMMA/ASA就是聚甲基丙烯酸甲酯/丙烯腈苯乙烯丙烯酸酯合金，结合了PMMA的高光泽和ASA的耐候性，常用于汽车外饰、户外电子、家电外壳、建筑材料、卫浴用品。
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PMMA/ASA（外企大厂）
通用级，参考价约20-30元/公斤。汽车外饰、户外电子、家电外壳。
高光泽级，参考价约22-33元/公斤。汽车外饰、卫浴用品、高端家电。
耐候级，参考价约23-35元/公斤。户外应用、汽车外饰、建筑材料。
国产PMMA/ASA（中企大厂）
通用级，参考价约15-24元/公斤。性价比高，通用注塑、汽车、电子。
高光泽级，参考价约17-27元/公斤。汽车外饰、卫浴用品、高端家电。
耐候级，参考价约18-28元/公斤。户外应用、汽车外饰、建筑材料。
一句话总结：国产通用15-24块，国产高光泽/耐候17-28块，进口通用20-30块，进口高光泽/耐候22-35块。你要的是啥PMMA比例和性能，决定了你该在哪一档选。
二、同是PMMA/ASA，价差凭什么这么大
PMMA/ASA的价格差，主要藏在四个地方。
第一，PMMA比例不同。PMMA比例20%左右便宜，比例50%以上高光泽但贵。PMMA比例越高，光泽度和硬度越好，但耐候性略降。
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，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，进口比国产贵30-50%，贵的是品控和研发。
三、采购避坑：别让PMMA比例骗了你
我见过太多采购，比价比到最后选了最便宜的十五的，然后做出来的制品光泽差、耐候差、客户退货，一次损失够买半年的好料。
PMMA/ASA采购这行，水比你想的深。三个坑必须绕开：
第一，看光泽度和耐候等级不看牌号。同一个牌号不同批次性能可能波动，拿到料先测光泽度和耐候等级，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PMMA/ASA卖，拿低PMMA比例当高比例卖。要COA、要PMMA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15块，做出来制品次品率5%；B料单价24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——比如要高光泽又要高耐候、要耐热又要高流动、要低成本又要电镀级——那不是PMMA/ASA的问题，是你需要的不是标准PMMA/ASA，是改性PMMA/ASA。
这时候可以看看宁波科隆新材目前在做的高性能改性PMMA/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PMMA/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，PMMA/ASA行情一天一个样，甲基丙烯酸甲酯、丙烯腈、苯乙烯、丙烯酸酯、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PMMA/ASA这事儿，十五的和三十五的，差的不是二十。
单价是门槛，选对PMMA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 PMMA/ASA per kilogram?
PMMA/ASA is not one material: weatherability, heat-resistant, electroplating, and each carries a different price.
1. Mainstream grade quotes (imported + domestic) — recent market references; live prices subject to same-day inquiry.
Imported PMMA/ASA
general-purpose, approx. CNY 20-30/kg. automotive exteriors; appliance housings.
approx. CNY 22-33/kg. automotive exteriors.
weatherability, approx. CNY 23-35/kg. outdoor applications; automotive exteriors; construction materials.
Domestic PMMA/ASA
general-purpose, approx. CNY 15-24/kg. general injection; automotive; electronics.
approx. CNY 17-27/kg. automotive exteriors.
weatherability, approx. CNY 18-28/kg. outdoor applications; automotive exteriors; construction materials.
2. Why prices differ so much
Four factors: (1) composition — lower levels are cheaper; higher levels give better performance but cost more. (2) weatherability 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 key properties 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 PMMA/ASA, you need a modified compound. Ningbo Kolong New Materials is developing high-performance modified PMMA/ASA solutions covering glass-fiber reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified PMMA/ASA 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; PMMA/ASA 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.
