PMMA多少钱一公斤？
这个问题一搜，从十二块一公斤到二十块一公斤，报价差得比透光率还多。有人说我买的十二块的三菱VH4-001用得挺好，有人说我买的二十块的万华HD03才叫高透射。到底差在哪？
说实话，问PMMA多少钱一公斤的人，大概率还没搞懂PMMA这东西不是一个料——通用级、高流动级、耐候级、高透射级、导光级，每个分支价格都不一样。你拿通用级的价和导光级比，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。
三菱化学（Mitsubishi，日本/南通）
VH001，注塑高透明耐候，参考价约15元/公斤。通用注塑、亚克力制品。
VH4-001，通用级，参考价约12元/公斤。性价比高，通用注塑。
VH5，板材级，参考价约12元/公斤。亚克力板材、挤出。
VRL-40，高流动级，参考价约22元/公斤。薄壁制品、导光板。
奇美（Chi Mei，中国台湾/镇江）
CM-207，耐高温光学级，参考价约13元/公斤。光学性能、热稳定。
CM-211，通用级，参考价约14元/公斤。高透明、注塑。
CM-203，高刚性，参考价约11元/公斤。亚克力板材、注塑。
CM-205，耐候级，参考价约14元/公斤。户外制品、抗UV。
万华化学（中企大厂）
HD01L，耐刮擦高透射耐候，参考价约19元/公斤。汽车领域、高端应用。
HD03，通用级，参考价约20元/公斤。性价比高，通用注塑。
HD01，通用级，参考价约15-18元/公斤。国产主力，通用注塑。
一句话总结：通用级11-15块，耐候/光学级13-16块，高透射/耐刮擦18-20块，导光/高流动20-22块。你要的是啥透光率和用途，决定了你该在哪一档选。
二、同是PMMA，价差凭什么这么大
PMMA的价格差，主要藏在四个地方。
第一，透光率不同。通用级透光率92%左右便宜，高透射级透光率93%以上贵。透光率是PMMA的核心指标，每提升0.5%价格都要加。
第二，流动性不同。通用流动适合普通注塑价格便宜，高流动适合薄壁和导光板价格贵。高流动PMMA需要特殊工艺。
第三，耐候性能不同。通用级耐候一般价格便宜，耐候级添加UV吸收剂价格贵。户外用PMMA必须耐候。
第四，品牌和产地。进口溢价高但光学性能稳定，国产性价比高但质量参差。同样是通用级，三菱比万华略贵，贵的是品控和光学一致性。
三、采购避坑：别让透光率骗了你
我见过太多采购，比价比到最后选了最便宜的十二块的，然后做出来的制品黄变、透光率不够、客户退货，一次损失够买半年的好料。
PMMA采购这行，水比你想的深。三个坑必须绕开：
第一，看透光率和熔指不看牌号。同一个牌号不同批次性能可能波动，拿到料先测透光率和熔指，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PS当PMMA卖，拿回收料当新料卖。要COA、要透光率检测、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，做出来次品率5%；B料单价18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——比如要阻燃又要高透明、要耐刮擦又要低成本、要导光又要耐候——那不是PMMA的问题，是你需要的不是标准PMMA，是改性PMMA。
这时候可以看看宁波科隆新材目前在做的高性能改性PMMA方案，阻燃、耐刮擦、导光、耐候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行情一天一个样，甲基丙烯酸甲酯、丙酮、氰化氢、汇率都在动。
如果你需要三菱、奇美、万华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这事儿，十二的和二十的，差的不是八块。
单价是门槛，选对透光率和用途才是底线。别让报价单上的数字迷惑了你——你买的不是一公斤塑料，是一公斤能做出高透明制品的方案。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 per kilogram?
PMMA is not one material: high-flow, weatherability, and each carries a different price.
1. Mainstream grade quotes (imported + domestic) — recent market references; live prices subject to same-day inquiry.
PMMA
VH001, injection high-transparency weather-resistant, approx. CNY 15/kg. general injection.
VH4-001, general-purpose, approx. CNY 12/kg. general injection.
VH5, approx. CNY 12/kg. extrusion.
VRL-40, high-flow, approx. CNY 22/kg. thin-wall parts.
Chi Mei
CM-207, high-temperature optical, approx. CNY 13/kg. heat-stabilized.
CM-211, general-purpose, approx. CNY 14/kg. high-transparency; injection.
CM-203, high-rigidity, approx. CNY 11/kg. injection.
CM-205, weatherability, approx. CNY 14/kg. UV-resistant.
Wanhua Chemical
HD01L, approx. CNY 19/kg. premium applications.
HD03, general-purpose, approx. CNY 20/kg. general injection.
HD01, general-purpose, approx. CNY 15-18/kg. general injection.
2. Why prices differ so much
Four factors: (1) composition — lower levels are cheaper; higher levels give better performance but cost more. (2) flow — 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, you need a modified compound. Ningbo Kolong New Materials is developing high-performance modified PMMA solutions covering glass-fiber reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified PMMA 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 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.
