PEEK多少钱一公斤？今日报价，塑料里的黄金不是噱头
PEEK多少钱一公斤？
这个问题一搜，从三百块一公斤到七百块一公斤，报价差得比耐温等级还多。有人说我买的三百多的中研股份用得挺好，有人说我买的七百块的威格斯450G才叫高性能。到底差在哪？
说实话，问PEEK多少钱一公斤的人，大概率还没搞懂PEEK这东西不是一个料——纯树脂、玻纤增强、碳纤增强、耐磨、医疗级，每个分支价格都不一样。你拿纯树脂的价和碳纤增强医疗级比，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。
威格斯（Victrex，英国）
450G，纯树脂通用级，参考价约365-700元/公斤。高刚性、耐高温260℃以上，食品医疗级，注塑挤出通用。
150G，纯树脂高流动，参考价约520-670元/公斤。阻燃V-0，电子电气、汽车部件、薄壁制品。
450FE20，20%石墨+PTFE耐磨，参考价约500-700元/公斤。超高耐磨，轴承、齿轮、密封件。
索尔维（Solvay，比利时）
KT-820SL45，45%碳纤增强，参考价约600-700元/公斤。KetaSpire系列，超高强度，航空航天、半导体。
AV-A GF30，30%玻纤增强，参考价约400-550元/公斤。高强度，工业部件、汽车。
赢创（Evonik，德国）
VESTAKEEP纯树脂，参考价约400-600元/公斤。耐高温、耐化学，医疗、工业。
中研股份（中企大厂）
330P，纯树脂，参考价约300-400元/公斤。国产主力，科创板上市公司，性价比高，通用注塑。
550G，纯树脂高刚性，参考价约350-450元/公斤。高强度，工业部件。
551LG，纯树脂高抗疲劳，参考价约380-480元/公斤。电线电缆、高端应用。
一句话总结：纯树脂300-500块，玻纤增强400-600块，碳纤增强500-700块，耐磨/医疗级500-800块。你要的是啥填充和等级，决定了你该在哪一档选。
二、同是PEEK，价差凭什么这么大
PEEK的价格差，主要藏在四个地方。
第一，填充类型不同。纯树脂相对便宜，玻纤增强贵一点，碳纤增强更贵，加PTFE/石墨耐磨最贵。填充决定了强度、导电、耐磨性能。
第二，纯度和等级不同。工业级便宜，医疗级/食品级贵很多。医疗级需要生物相容认证，价格翻倍。
第三，分子量和流动性不同。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，威格斯比中研股份贵50-100%，贵的是品控和研发。
三、采购避坑：别让纯度骗了你
我见过太多采购，比价比到最后选了最便宜的三百块的，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。
PEEK采购这行，水比你想的深。三个坑必须绕开：
第一，看灰分和热变形温度不看牌号。同一个牌号不同批次填充量可能波动，拿到料先测灰分和HDT，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PEK当PEEK卖，拿回料当新料卖。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300块，做出来次品率5%；B料单价500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——比如要耐磨又要高流动、要增强又要导电、要医疗级又要低成本——那不是PEEK的问题，是你需要的不是标准PEEK，是改性PEEK。
这时候可以看看宁波科隆新材目前在做的高性能改性PEEK方案，玻纤增强、碳纤增强、耐磨、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PEEK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，PEEK行情一天一个样，原油、4,4-二氟二苯甲酮、对苯二酚、汇率都在动。
如果你需要威格斯、索尔维、赢创、中研股份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PEEK这事儿，三百的和七百的，差的不是四百。
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 PEEK per kilogram?
PEEK is not one material: wear-resistant, and each carries a different price.
1. Mainstream grade quotes (imported + domestic) — recent market references; live prices subject to same-day inquiry.

2. Why prices differ so much
Four factors: (1) fillers type — lower levels are cheaper; higher levels give better performance but cost more. (2) grade level — 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 PEEK, you need a modified compound. Ningbo Kolong New Materials is developing high-performance modified PEEK solutions covering glass-fiber reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified PEEK 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; PEEK 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.
