PEBA多少钱一公斤?
这个问题一搜,从五十块一公斤到一百五十块一公斤,报价差得比聚醚含量还多。有人说我买的五十的国产通用用得挺好,有人说我买的一百五十的进口高弹性才叫高端。到底差在哪?
说实话,问PEBA多少钱一公斤的人,大概率还没搞懂PEBA这东西不是一个料——通用级、高弹性级、医用级、食品级、导电级,每个分支价格都不一样。你拿通用级的价和高弹性比,那不叫比价,叫被忽悠。
PEBA就是聚醚嵌段酰胺,由聚酰胺硬段和聚醚软段嵌段共聚制得,高弹性、耐低温、轻量化,常用于运动鞋底、医疗器械、汽车配件、电子电器、工业软管。
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PEBA(外企大厂)
通用级,参考价约80-120元/公斤。运动鞋底、汽车配件、电子电器。
高弹性级,参考价约100-140元/公斤。高端运动鞋底、医疗器械、工业软管。
医用级,参考价约120-150元/公斤。医疗器械、医用耗材、食品接触。
国产PEBA(中企大厂)
通用级,参考价约50-85元/公斤。性价比高,运动鞋底、汽车配件、电子电器。
高弹性级,参考价约65-105元/公斤。高端运动鞋底、医疗器械、工业软管。
导电级,参考价约75-120元/公斤。电子电器、防静电应用、特殊制品。
一句话总结:国产通用50-85块,国产高弹性/导电65-120块,进口通用80-120块,进口高弹性/医用100-150块。你要的是啥聚醚含量和性能,决定了你该在哪一档选。
二、同是PEBA,价差凭什么这么大
PEBA的价格差,主要藏在四个地方。
第一,聚醚含量不同。低聚醚便宜,高聚醚贵。聚醚含量越高,弹性和耐低温性越好,但强度略降。
第二,硬度不同。高硬度便宜,低硬度贵。低硬度弹性好,但价格更高。
第三,用途不同。通用级便宜,医用/食品级贵。特殊用途需要特殊认证,价格更高。
第四,品牌和产地。进口溢价高但批次稳定,国产性价比高但牌号少。同样是高弹性级,进口比国产贵30-50%,贵的是品控和研发。
三、采购避坑:别让聚醚含量骗了你
我见过太多采购,比价比到最后选了最便宜的五十的,然后做出来的鞋底弹性差、回弹不够、客户退货,一次损失够买半年的好料。
PEBA采购这行,水比你想的深。三个坑必须绕开:
第一,看硬度和回弹率不看牌号。同一个牌号不同批次性能可能波动,拿到料先测硬度和回弹率,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TPU当PEBA卖,拿低聚醚当高聚醚卖。要COA、要聚醚含量检测、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50块,做出来鞋底次品率5%;B料单价85块,次品率1%。算到每双鞋上,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——比如要高弹性又要高强度、要耐低温又要耐化学、要低成本又要医用级——那不是PEBA的问题,是你需要的不是标准PEBA,是改性PEBA。
这时候可以看看宁波科隆新材目前在做的高性能改性PEBA方案,玻纤增强、阻燃、耐候、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PEBA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,PEBA行情一天一个样,己内酰胺、聚醚多元醇、催化剂、导电剂、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PEBA这事儿,五十的和一百五十的,差的不是一百。
单价是门槛,选对聚醚含量和性能才是底线。别让报价单上的数字迷惑了你——你买的不是一公斤塑料,是一公斤能做出高回弹运动鞋底的方案。把账算到每双鞋上,再加上次品退货损失,你才知道谁真便宜谁真贵。

How much is PEBA per kilogram?
PEBA is not one material: high-elasticity, medical, food-grade, and each carries a different price.
1. Mainstream grade quotes (imported + domestic) — recent market references; live prices subject to same-day inquiry.
Imported PEBA
general-purpose, approx. CNY 80-120/kg. automotive parts; electronics.
high-elasticity, approx. CNY 100-140/kg. medical devices; industrial hoses.
medical, approx. CNY 120-150/kg. medical devices; food contact.
Domestic PEBA
general-purpose, approx. CNY 50-85/kg. automotive parts; electronics.
high-elasticity, approx. CNY 65-105/kg. medical devices; industrial hoses.
approx. CNY 75-120/kg. electronics.
2. Why prices differ so much
Four factors: (1) composition — lower levels are cheaper; higher levels give better performance but cost more. (2) hardness — 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 PEBA, you need a modified compound. Ningbo Kolong New Materials is developing high-performance modified PEBA solutions covering glass-fiber reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified PEBA 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; PEBA 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.
