PEEK/PTFE多少钱一公斤?
这个问题一搜,从四百块一公斤到一千二百块一公斤,报价差得比PTFE比例还多。有人说我买的四百的国产通用用得挺好,有人说我买的一千二百的进口高耐磨才叫高端。到底差在哪?
说实话,问PEEK/PTFE多少钱一公斤的人,大概率还没搞懂PEEK/PTFE这东西不是一个料——通用级、高耐磨级、高强度级、自润滑级、特种级,每个分支价格都不一样。你拿通用级的价和高耐磨比,那不叫比价,叫被忽悠。
PEEK/PTFE就是聚醚醚酮/聚四氟乙烯合金,结合了PEEK的高强度和PTFE的自润滑耐磨,常用于航空航天、半导体、工业机械、耐磨零部件、特殊应用。
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PEEK/PTFE(外企大厂)
通用级,参考价约600-900元/公斤。航空航天、半导体、工业机械。
高耐磨级,参考价约800-1100元/公斤。耐磨零部件、工业机械、特殊应用。
自润滑级,参考价约900-1200元/公斤。轴承、密封件、特殊应用。
国产PEEK/PTFE(中企大厂)
通用级,参考价约400-650元/公斤。性价比高,航空航天、半导体、工业机械。
高耐磨级,参考价约550-850元/公斤。耐磨零部件、工业机械、特殊应用。
玻纤增强级,参考价约500-800元/公斤。结构件、航空航天、工业机械。
一句话总结:国产通用400-650块,国产高耐磨/玻纤增强500-850块,进口通用600-900块,进口高耐磨/自润滑800-1200块。你要的是啥PTFE比例和性能,决定了你该在哪一档选。
二、同是PEEK/PTFE,价差凭什么这么大
PEEK/PTFE的价格差,主要藏在四个地方。
第一,PTFE比例不同。低PTFE便宜,高PTFE贵。PTFE比例越高,自润滑性和耐磨性越好,但强度略降。
第二,耐磨等级不同。通用级便宜,高耐磨级贵。高耐磨需要特殊PTFE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。同样是高耐磨级,进口比国产贵30-50%,贵的是品控和研发。
三、采购避坑:别让PTFE比例骗了你
我见过太多采购,比价比到最后选了最便宜的四百的,然后做出来的制品耐磨差、摩擦系数高、客户退货,一次损失够买半年的好料。
PEEK/PTFE采购这行,水比你想的深。三个坑必须绕开:
第一,看摩擦系数和磨损率不看牌号。同一个牌号不同批次性能可能波动,拿到料先测摩擦系数和磨损率,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PEEK/PTFE卖,拿低PTFE当高PTFE卖。要COA、要PTFE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400块,做出来制品次品率5%;B料单价650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——比如要高耐磨又要高强度、要自润滑又要耐热、要低成本又要特种级——那不是PEEK/PTFE的问题,是你需要的不是标准PEEK/PTFE,是改性PEEK/PTFE。
这时候可以看看宁波科隆新材目前在做的高性能改性PEEK/PTFE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/PTFE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/PTFE行情一天一个样,聚醚醚酮、聚四氟乙烯、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PEEK/PTFE这事儿,四百的和一千二百的,差的不是八百。
单价是门槛,选对PTFE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,是一公斤能做出高耐磨自润滑零部件的方案。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。

How much is PEEK/PTFE per kilogram?
PEEK/PTFE is not one material: different grades, and each carries a different price.
1. Mainstream grade quotes (imported + domestic) — recent market references; live prices subject to same-day inquiry.
Imported PEEK/PTFE
general-purpose, approx. CNY 600-900/kg. aerospace; semiconductors; industrial machinery.
approx. CNY 800-1100/kg. industrial machinery; special applications.
approx. CNY 900-1200/kg. bearings; seals; special applications.
Domestic PEEK/PTFE
general-purpose, approx. CNY 400-650/kg. aerospace; semiconductors; industrial machinery.
approx. CNY 550-850/kg. industrial machinery; special applications.
GF-reinforced, approx. CNY 500-800/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) grade level — 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 PEEK/PTFE, you need a modified compound. Ningbo Kolong New Materials is developing high-performance modified PEEK/PTFE solutions covering glass-fiber reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified PEEK/PTFE 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/PTFE 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.
