PBI/PEEK塑料合金多少钱一公斤？
这个问题一搜，从三百块一公斤到一千块一公斤，报价差得比PBI比例还多。有人说我买的三百的国产通用用得挺好，有人说我买的一千的进口超高耐热才叫高端。到底差在哪？
说实话，问PBI/PEEK塑料合金多少钱一公斤的人，大概率还没搞懂PBI/PEEK这东西不是一个料——通用级、超高耐热级、高强度级、耐磨级、特种级，每个分支价格都不一样。你拿通用级的价和超高耐热比，那不叫比价，叫被忽悠。
PBI/PEEK塑料合金就是聚苯并咪唑/聚醚醚酮合金，结合了PBI的超高耐热和PEEK的高强度易加工，常用于航空航天、半导体、工业机械、高温应用、特殊零部件。
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PBI/PEEK（外企大厂）
通用级，参考价约500-750元/公斤。航空航天、半导体、工业机械。
超高耐热级，参考价约700-950元/公斤。高温应用、特殊零部件、航空航天。
高强度级，参考价约750-1000元/公斤。结构件、航空航天、特殊应用。
国产PBI/PEEK（中企大厂）
通用级，参考价约300-500元/公斤。性价比高，航空航天、半导体、工业机械。
超高耐热级，参考价约450-700元/公斤。高温应用、特殊零部件、航空航天。
玻纤增强级，参考价约400-650元/公斤。结构件、航空航天、工业机械。
一句话总结：国产通用300-500块，国产超高耐热/玻纤增强400-700块，进口通用500-750块，进口超高耐热/高强度700-1000块。你要的是啥PBI比例和性能，决定了你该在哪一档选。
二、同是PBI/PEEK，价差凭什么这么大
PBI/PEEK的价格差，主要藏在四个地方。
第一，PBI比例不同。低PBI便宜，高PBI贵。PBI比例越高，耐热性越好，但价格更高。
第二，耐热等级不同。通用级便宜，超高耐热级贵。超高耐热需要特殊PBI含量，价格更高。
第三，增强方式不同。无筋通用便宜，玻纤/碳纤增强贵。增强比无筋通用贵20-40%。
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。同样是超高耐热级，进口比国产贵30-50%，贵的是品控和研发。
三、采购避坑：别让PBI比例骗了你
我见过太多采购，比价比到最后选了最便宜的三百的，然后做出来的制品耐热差、强度不够、客户退货，一次损失够买半年的好料。
PBI/PEEK采购这行，水比你想的深。三个坑必须绕开：
第一，看热变形温度和拉伸强度不看牌号。同一个牌号不同批次性能可能波动，拿到料先测热变形温度和拉伸强度，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PEEK当PBI/PEEK卖，拿低PBI当高PBI卖。要COA、要PBI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300块，做出来制品次品率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——比如要超高耐热又要高强度、要耐磨又要高流动、要低成本又要特种级——那不是PBI/PEEK的问题，是你需要的不是标准PBI/PEEK，是改性PBI/PEEK。
这时候可以看看宁波科隆新材目前在做的高性能改性PBI/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PBI/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，PBI/PEEK行情一天一个样，聚苯并咪唑、聚醚醚酮、玻纤、碳纤、耐磨剂、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PBI/PEEK这事儿，三百的和一千的，差的不是七百。
单价是门槛，选对PBI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，是一公斤能做出超高耐热航空航天零部件的方案。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。

PBI/PEEK加工常见问题及解决
How much is PBI/PEEK per kilogram?
PBI/PEEK is not one material: ultra-high-heat, wear-resistant, and each carries a different price.
1. Mainstream grade quotes (imported + domestic) — recent market references; live prices subject to same-day inquiry.
Imported PBI/PEEK
general-purpose, approx. CNY 500-750/kg. aerospace; semiconductors; industrial machinery.
ultra-high-heat, approx. CNY 700-950/kg. aerospace.
approx. CNY 750-1000/kg. structural parts; aerospace; special applications.
Domestic PBI/PEEK
general-purpose, approx. CNY 300-500/kg. aerospace; semiconductors; industrial machinery.
ultra-high-heat, approx. CNY 450-700/kg. aerospace.
GF-reinforced, approx. CNY 400-650/kg. structural parts; aerospace; industrial machinery.
2. Why prices differ so much
Four factors: (1) composition — lower levels are cheaper; higher levels give better performance but cost more. (2) heat grade — premium grades need special formulations and cost more. (3) reinforcement — 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 PBI/PEEK, you need a modified compound. Ningbo Kolong New Materials is developing high-performance modified PBI/PEEK solutions covering glass-fiber reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified PBI/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; PBI/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.
