PEI多少钱一公斤？新手避坑，琥珀色透明的耐高温料不便宜
PEI多少钱一公斤？
这个问题一搜，从八十块一公斤到两百块一公斤，报价差得比耐温等级还多。有人说我买的一百零五的沙伯基础2200用得挺好，有人说我买的两百块的Ultem 1000FV才叫高性能。到底差在哪？
说实话，问PEI多少钱一公斤的人，大概率还没搞懂PEI这东西不是一个料——纯树脂、玻纤增强、碳纤增强、食品级、医疗级，每个分支价格都不一样。你拿玻纤增强的价和纯树脂医疗级比，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。
SABIC（沙伯基础，原GE）
Ultem 1000，纯树脂通用级，参考价约120-200元/公斤。琥珀色透明，耐温201℃，阻燃V0，电子电器、医疗。
Ultem 1000R，纯树脂高流动，参考价约120-160元/公斤。薄壁制品、复杂结构件。
Ultem 1010F，高流动高韧性，参考价约140-180元/公斤。食品接触级，高端应用。
Ultem 2100，10%玻纤增强，参考价约130元/公斤。高强度，阻燃，结构件。
Ultem 2200，20%玻纤增强，参考价约105元/公斤。可食品接触，高强度。
Ultem 2300R，30%玻纤增强，参考价约107元/公斤。耐高温防火V0，高强度。
三菱化学（Mitsubishi）
三菱PEI通用级，参考价约100-180元/公斤。日本品牌，质量稳定。
中福实业/国产（中企）
国产PEI纯树脂，参考价约80-150元/公斤。性价比高，通用注塑、电子电器。
国产PEI玻纤增强，参考价约70-120元/公斤。增强级，结构件。
一句话总结：纯树脂100-200块，玻纤增强70-130块，食品/医疗级150-250块，3D打印级400-600块。你要的是啥填充和等级，决定了你该在哪一档选。
二、同是PEI，价差凭什么这么大
PEI的价格差，主要藏在四个地方。
第一，填充类型不同。纯树脂贵，玻纤增强便宜一点（玻纤降低了单位成本），碳纤增强更贵。填充决定了强度、刚性、价格。
第二，流动性不同。高流动适合薄壁注塑，加工窗口宽，价格也贵；通用流动价格适中。
第三，等级不同。工业级便宜，食品级/医疗级贵很多。医疗级需要生物相容认证，价格翻倍。3D打印级（如9085）更是天价。
第四，品牌和产地。进口溢价高但批次稳定，国产性价比高但质量参差。同样是纯树脂，SABIC比国产贵30-50%，贵的是品控和研发。
三、采购避坑：别让颜色骗了你
我见过太多采购，比价比到最后选了最便宜的八十块的，然后做出来的制品耐温不够、强度不行、客户退货，一次损失够买半年的好料。
PEI采购这行，水比你想的深。三个坑必须绕开：
第一，看热变形温度和密度不看牌号。同一个牌号不同批次性能可能波动，拿到料先测HDT和密度，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PES/PSU当PEI卖，拿玻纤增强当纯树脂卖。要COA、要物性报告、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80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——比如要阻燃又要高流动、要增强又要透明、要医疗级又要低成本——那不是PEI的问题，是你需要的不是标准PEI，是改性PEI。
这时候可以看看宁波科隆新材目前在做的高性能改性PEI方案，玻纤增强、碳纤增强、阻燃、耐磨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PEI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，PEI行情一天一个样，原油、双酚A二酐、间苯二胺、汇率都在动。
如果你需要SABIC、三菱、国产PEI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PEI这事儿，八十的和两百的，差的不是一百二。
单价是门槛，选对填充类型和等级才是底线。别让报价单上的数字迷惑了你——你买的不是一公斤塑料，是一公斤能做出合格制品的方案。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 PEI per kilogram?
PEI is not one material: food-grade, and each carries a different price.
1. Mainstream grade quotes (imported + domestic) — recent market references; live prices subject to same-day inquiry.
SABIC
Ultem 1000, approx. CNY 120-200/kg. electronics.
Ultem 1000R, approx. CNY 120-160/kg. thin-wall parts; complex structural parts.
Ultem 1010F, high-flow high toughness, approx. CNY 140-180/kg. premium applications.
Ultem 2100, approx. CNY 130/kg. high-strength; flame-retardant; structural parts.
Ultem 2200, approx. CNY 105/kg. high-strength.
Ultem 2300R, approx. CNY 107/kg. high-strength.
PEI
approx. CNY 100-180/kg.
Domestic PEI
approx. CNY 80-150/kg. general injection; electronics.
approx. CNY 70-120/kg. reinforced; structural parts.
2. Why prices differ so much
Four factors: (1) fillers type — 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 PEI, you need a modified compound. Ningbo Kolong New Materials is developing high-performance modified PEI solutions covering glass-fiber reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified PEI 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; PEI 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.
