TPU多少钱一公斤?标准和改性价格差,差在配方不在标签
TPU多少钱一公斤?
这个问题一搜,从二十块一公斤到五十五块一公斤,报价差得比硬度还多。有人说我买的二十五块的万华用得挺好,有人说我买的五十五块的巴斯夫1075AU才叫耐水解。到底差在哪?
说实话,问TPU多少钱一公斤的人,大概率还没搞懂TPU这东西不是一个料——聚酯型、聚醚型、聚己内酯型,每个分支价格都不一样。你拿聚酯型的价和聚醚型比,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。
巴斯夫(BASF)
1185A,聚酯型85A,参考价约30-35元/公斤。Elastollan系列,耐磨、高拉伸,管材、密封件。
1075AU,聚醚型75A抗UV,参考价约55元/公斤。耐磨损、抗UV、耐水解,户外制品、线缆。
L785A,脂肪族TPU,参考价约35元/公斤。不黄变、耐候,高端户外、光学应用。
科思创(Covestro,原拜耳)
345X,聚酯型,参考价约25-30元/公斤。Desmopan系列,机械强度高,电线电缆。
110 FR,阻燃V0级,参考价约32元/公斤。防火透明,电子电器、线缆。
路博润(Lubrizol)
58889,聚酯型89A,参考价约35-40元/公斤。Estane系列,高耐磨,管材、薄膜。
5708,溶剂型TPU,参考价约30-35元/公斤。粘合剂、油墨专用。
万华化学(中企大厂)
万华TPU 85A,聚酯型通用级,参考价约20-25元/公斤。国产主力,性价比高,管材、密封件、鞋材。
万华TPU 95A,聚醚型,参考价约25-30元/公斤。耐水解,户外制品、线缆。
一句话总结:聚酯型20-35块,聚醚型25-45块,脂肪族35-55块,阻燃/特殊级30-50块。你要的是啥体系和硬度,决定了你该在哪一档选。
二、同是TPU,价差凭什么这么大
TPU的价格差,主要藏在四个地方。
第一,多元醇体系不同。聚酯型便宜,聚醚型贵一点,聚己内酯型更贵,脂肪族最贵。体系决定了耐水解、耐候、耐油性能。
第二,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。
第三,功能改性不同。阻燃、耐水解、抗UV、食品级、医疗级——这些都要加钱。你买的不是纯TPU,是加了料的TPU方案。
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。同样是聚醚型,巴斯夫比万华贵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块的,然后做出来的制品耐水解差、回弹不够、客户退货,一次损失够买半年的好料。
TPU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。有些贸易商拿聚酯型当聚醚型卖,拿填充料当纯料卖。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20块,做出来次品率5%;B料单价30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TPU的问题,是你需要的不是标准TPU,是改性TPU。
这时候可以看看宁波科隆新材目前在做的高性能改性TPU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TPU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,TPU行情一天一个样,原油、MDI、多元醇、汇率都在动。
如果你需要巴斯夫、科思创、路博润、万华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TPU这事儿,二十的和五十五的,差的不是三十五。
单价是门槛,选对体系和硬度才是底线。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 TPU per kilogram?
TPU 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.
BASF
1185A, approx. CNY 30-35/kg. wear-resistant; pipe; seals.
1075AU, approx. CNY 55/kg. UV-resistant; hydrolysis-resistant.
L785A, approx. CNY 35/kg. weather-resistant; optical applications.
Covestro
345X, approx. CNY 25-30/kg. wire and cable.
110 FR, approx. CNY 32/kg. electronics.
Lubrizol
58889, approx. CNY 35-40/kg. high-wear; pipe; film.

approx. CNY 25-30/kg. hydrolysis-resistant.
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) 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 TPU, you need a modified compound. Ningbo Kolong New Materials is developing high-performance modified TPU solutions covering glass-fiber reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified TPU 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; TPU 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.
