TPEE多少钱一公斤?行情走势,聚酯弹性体的价格藏在硬度里
TPEE多少钱一公斤?
这个问题一搜,从二十五块一公斤到五十五块一公斤,报价差得比硬度还多。有人说我买的三十块的长春用得挺好,有人说我买的五十五块的杜邦Hytrel才叫耐疲劳。到底差在哪?
说实话,问TPEE多少钱一公斤的人,大概率还没搞懂TPEE这东西不是一个料——邵氏D硬度不同、聚酯/聚醚比例不同、功能改性不同,每个分支价格都不一样。你拿低硬度的价和高硬度耐疲劳比,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。
杜邦(DuPont,现塞拉尼斯)
Hytrel 5556,55D通用级,参考价约45-60元/公斤。耐疲劳、耐磨,软管、线缆、汽车部件。
Hytrel 6356,63D高硬度,参考价约40-50元/公斤。高强度,无声齿轮、结构件。
Hytrel 4056,40D低硬度,参考价约50-60元/公斤。高弹性,密封件、减震。
AMX1218,抗UV耐寒,参考价约55元/公斤。电缆护套、户外制品。
塞拉尼斯(Celanese)
RITEFLEX 655A,65A通用级,参考价约53元/公斤。注塑级,通用弹性件。
长春化工(Chang Chun)
长春TPEE通用级,参考价约30-45元/公斤。台湾品牌,性价比高,软管、线缆、鞋材。
中蓝晨光(中企大厂)
H5550E,55D电缆级,参考价约25-35元/公斤。国产主力,性价比高,电缆护套、光纤松套管。
晨光TPEE通用级,参考价约25-40元/公斤。汽车、工业、日用品。
一句话总结:通用级25-40块,高硬度40-50块,低硬度/特殊级50-60块,抗UV/耐候55-65块。你要的是啥硬度和功能,决定了你该在哪一档选。
二、同是TPEE,价差凭什么这么大
TPEE的价格差,主要藏在四个地方。
第一,硬度不同。邵氏硬度越低(越软),价格通常越贵;高硬度相对便宜。硬度由硬段/软段比例决定,软段越多成本越高。
第二,软段类型不同。聚醚软段耐水解、耐低温,价格贵;聚酯软段强度好、成本低,但耐水解差。
第三,功能改性不同。抗UV、耐候、阻燃、食品级——这些都要加钱。抗UV级比通用级贵20-30%。
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55D,杜邦比中蓝晨光贵50-100%,贵的是品控和研发。
三、采购避坑:别让硬度骗了你
我见过太多采购,比价比到最后选了最便宜的二十五块的,然后做出来的制品耐疲劳差、回弹不够、客户退货,一次损失够买半年的好料。
TPEE采购这行,水比你想的深。三个坑必须绕开:
第一,看硬度和拉伸强度不看牌号。同一个牌号不同批次硬度可能波动,拿到料先测硬度和拉伸,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TPE/TPU当TPEE卖,拿聚酯软段当聚醚软段卖。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25块,做出来次品率5%;B料单价45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——比如要阻燃又要高回弹、要耐水解又要抗UV、要食品级又要低成本——那不是TPEE的问题,是你需要的不是标准TPEE,是改性TPEE。
这时候可以看看宁波科隆新材目前在做的高性能改性TPEE方案,阻燃、耐水解、抗UV、玻纤增强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TPEE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,TPEE行情一天一个样,原油、PBT、PTMEG、汇率都在动。
如果你需要杜邦、塞拉尼斯、长春、中蓝晨光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TPEE这事儿,二十五的和五十五的,差的不是三十。
单价是门槛,选对硬度和软段类型才是底线。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 TPEE per kilogram?
TPEE 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.

2. Why prices differ so much
Four factors: (1) hardness — lower levels are cheaper; higher levels give better performance but cost more. (2) grade level — premium grades need special formulations and cost more. (3) functional modification — 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 TPEE, you need a modified compound. Ningbo Kolong New Materials is developing high-performance modified TPEE solutions covering glass-fiber reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified TPEE 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; TPEE 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.
