PC/PMMA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PC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透明才叫高端。到底差在哪？
说实话，问PC/PMMA多少钱一公斤的人，大概率还没搞懂PC/PMMA这东西不是一个料——通用级、高透明级、耐候级、耐热级、光学级，每个分支价格都不一样。你拿通用级的价和光学级比，那不叫比价，叫被忽悠。
PC/PMMA就是聚碳酸酯/聚甲基丙烯酸甲酯合金，结合了PC的韧性和PMMA的高透明，常用于汽车灯罩、光学镜片、家电面板、手机外壳、医疗器械。
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PC/PMMA（外企大厂）
通用级，参考价约25-38元/公斤。汽车灯罩、家电面板、电子电器。
高透明级，参考价约28-42元/公斤。光学镜片、手机外壳、高端家电。
光学级，参考价约30-45元/公斤。光学应用、汽车灯罩、高端电子。
国产PC/PMMA（中企大厂）
通用级，参考价约18-30元/公斤。性价比高，通用注塑、汽车、电子。
高透明级，参考价约20-35元/公斤。光学镜片、手机外壳、高端家电。
光学级，参考价约22-38元/公斤。光学应用、汽车灯罩、高端电子。
一句话总结：国产通用18-30块，国产高透明/光学20-38块，进口通用25-38块，进口高透明/光学28-45块。你要的是啥PC比例和性能，决定了你该在哪一档选。
二、同是PC/PMMA，价差凭什么这么大
PC/PMMA的价格差，主要藏在四个地方。
第一，PC比例不同。PC比例30%左右便宜，比例70%以上高韧性但贵。PC比例越高，韧性和耐热性越好，但透明度略降。
第二，透明等级不同。通用级便宜，高透明/光学级贵。高透明需要特殊工艺，价格更高。
第三，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。同样是光学级，进口比国产贵30-50%，贵的是品控和研发。
三、采购避坑：别让PC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，然后做出来的制品透明差、有黄变、客户退货，一次损失够买半年的好料。
PC/PMMA采购这行，水比你想的深。三个坑必须绕开：
第一，看透光率和黄变指数不看牌号。同一个牌号不同批次性能可能波动，拿到料先测透光率和黄变指数，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PC当PC/PMMA卖，拿低PC比例当高比例卖。要COA、要PC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30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——比如要高透明又要高耐候、要耐热又要高流动、要低成本又要光学级——那不是PC/PMMA的问题，是你需要的不是标准PC/PMMA，是改性PC/PMMA。
这时候可以看看宁波科隆新材目前在做的高性能改性PC/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PC/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，PC/PMMA行情一天一个样，双酚A、甲基丙烯酸甲酯、光气、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PC/PMMA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PC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，是一公斤能做出高透明汽车灯罩的方案。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 PC/PMMA per kilogram?
PC/PMMA is not one material: high-transparency, weatherability, heat-resistant, optical, and each carries a different price.
1. Mainstream grade quotes (imported + domestic) — recent market references; live prices subject to same-day inquiry.
Imported PC/PMMA
general-purpose, approx. CNY 25-38/kg. electronics.
high-transparency, approx. CNY 28-42/kg. optical lenses.
optical, approx. CNY 30-45/kg. optical applications.
Domestic PC/PMMA
general-purpose, approx. CNY 18-30/kg. general injection; automotive; electronics.
high-transparency, approx. CNY 20-35/kg. optical lenses.
optical, approx. CNY 22-38/kg. optical applications.
2. Why prices differ so much
Four factors: (1) composition — lower levels are cheaper; higher levels give better performance but cost more. (2) transparency grade — premium grades need special formulations and cost more. (3) weatherability grade — 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 PC/PMMA, you need a modified compound. Ningbo Kolong New Materials is developing high-performance modified PC/PMMA solutions covering glass-fiber reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified PC/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; PC/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.
