PES多少钱一公斤？
这个问题一搜，从四十块一公斤到二百六十块一公斤，报价差得比分子量还多。有人说我买的四十的巴斯夫E2010用得挺好，有人说我买的二百六的索尔维Veradel A-301才叫高端。到底差在哪？
说实话，问PES多少钱一公斤的人，大概率还没搞懂PES这东西不是一个料——注塑级、挤出级、薄膜级、粉末级、医疗级，每个分支价格都不一样。你拿通用注塑级的价和高端粉末比，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。
巴斯夫（BASF，德国）
Ultrason E2010，通用注塑级，参考价约40-100元/公斤。尺寸稳定、高流动、耐高温。
Ultrason E2010 HC，高纯度医疗级，参考价约155元/公斤。医疗器械、食品接触。
Ultrason E6020，医疗过滤高压膜支撑层，参考价约104.5元/公斤。膜专用片状粉末、超高粘度。
Ultrason E3010，挤出级，参考价约80-120元/公斤。板材、管材、薄膜。
Ultrason E1010，耐高温注塑级，参考价约100元/公斤。高端注塑、电子电器。
索尔维（Solvay，比利时）
Veradel 3400P，高韧性耐热粉末，参考价约249元/公斤。汽车部件、高端应用。
Veradel A-301，高流动PESU粉末，参考价约260元/公斤。高端注塑、精密部件。
Veradel AG-330，30%玻纤增强，参考价约200-250元/公斤。结构件、耐高温部件。
住友化学（Sumitomo，日本）
住友PES 3600G，通用级，参考价约120-180元/公斤。电子电器、汽车部件。
国产PES
国产PES通用注塑级，参考价约80-120元/公斤。性价比高，通用注塑、电子电器。
国产PES挤出级，参考价约70-100元/公斤。板材、管材、薄膜。
一句话总结：通用注塑级40-100块，挤出/薄膜级70-120块，医疗/高纯度100-160块，高端粉末/玻纤增强200-260块。你要的是啥分子量和用途，决定了你该在哪一档选。
二、同是PES，价差凭什么这么大
PES的价格差，主要藏在四个地方。
第一，分子量不同。低分子量适合注塑价格便宜，高分子量适合挤出和薄膜价格贵，超高粘度粉末用于膜支撑层价格更贵。
第二，纯度不同。工业级纯度适中价格便宜，医疗级/食品级纯度高价格贵。医疗级PES需要生物相容性认证。
第三，形态不同。颗粒适合注塑挤出价格适中，粉末适合涂层和膜价格高。粉末加工难度大，价格也高。
第四，品牌和产地。进口溢价高但批次稳定，国产性价比高但高端牌号少。同样是通用级，索尔维比国产贵1-2倍，贵的是品控和研发。
三、采购避坑：别让分子量骗了你
我见过太多采购，比价比到最后选了最便宜的四十块的，然后做出来的制品耐热不够、膜强度差、客户退货，一次损失够买半年的好料。
PES采购这行，水比你想的深。三个坑必须绕开：
第一，看熔指和玻璃化转变温度不看牌号。同一个牌号不同批次性能可能波动，拿到料先测熔指和Tg，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PSU当PES卖，拿工业级当医疗级卖。要COA、要分子量检测、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40块，做出来次品率5%；B料单价150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、要增强又要耐水解、要低成本又要医疗级——那不是PES的问题，是你需要的不是标准PES，是改性PES。
这时候可以看看宁波科隆新材目前在做的高性能改性PES方案，玻纤增强、阻燃、耐水解、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PES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，PES行情一天一个样，双酚S、4,4'-二氯二苯砜、汇率都在动。
如果你需要巴斯夫、索尔维、住友、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PES这事儿，四十的和二百六的，差的不是二百二。
单价是门槛，选对分子量和纯度才是底线。别让报价单上的数字迷惑了你——你买的不是一公斤塑料，是一公斤能做出耐高温制品的方案。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 PES per kilogram?
PES is not one material: extrusion, film, powder, and each carries a different price.
1. Mainstream grade quotes (imported + domestic) — recent market references; live prices subject to same-day inquiry.
BASF
Ultrason E2010, approx. CNY 40-100/kg. dimensional stability; high-flow; high-temperature.
Ultrason E2010 HC, approx. CNY 155/kg. medical devices; food contact.
Ultrason E6020, approx. CNY 104.5/kg.
Ultrason E3010, extrusion, approx. CNY 80-120/kg. sheet; pipe; film.
Ultrason E1010, high-temperature injection, approx. CNY 100/kg. electronics.
PES
Veradel 3400P, approx. CNY 249/kg. automotive parts; premium applications.
Veradel A-301, approx. CNY 260/kg. precision parts.
Veradel AG-330, approx. CNY 200-250/kg. structural parts.
Sumitomo Chemical
general-purpose, approx. CNY 120-180/kg. electronics; automotive parts.
Domestic PES

2. Why prices differ so much
Four factors: (1) molecular weight — lower levels are cheaper; higher levels give better performance but cost more. (2) purity — premium grades need special formulations and cost more. (3) form — 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 PES, you need a modified compound. Ningbo Kolong New Materials is developing high-performance modified PES solutions covering glass-fiber reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified PES 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; PES 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.
