TPE多少钱一公斤?选型省钱,别为用不上的性能买单
TPE多少钱一公斤?
这个问题一搜,从十二块一公斤到六十块一公斤,报价差得比硬度还多。有人说我买的十七块的李长荣用得挺好,有人说我买的四十五块的科腾G1651才叫耐老化。到底差在哪?
说实话,问TPE多少钱一公斤的人,大概率还没搞懂TPE这东西不是一个料——SBS、SEBS、TPEE、TPV、TPU,每个分支价格都不一样。你拿SBS的价和TPEE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。
科腾(Kraton)
G1651,SEBS高弹性,参考价约45元/公斤。抗氧化、耐老化,塑料改性、玩具、线材。
G1653V,SEBS高弹性,参考价约32-35元/公斤。耐老化、环保,医疗器械、共混改性。
D1155,SBS高硬度,参考价约32-33元/公斤。高内聚力,喷胶、胶粘剂。
李长荣(LCY)
7550,SEBS通用级,参考价约17-18元/公斤。惠州李长荣产,性价比高,塑料增韧、TPE原料。
7551,SEBS高弹性,参考价约18-20元/公斤。高回弹,玩具、线材、密封件。
杜邦(DuPont)
Hytrel 5556,TPEE聚酯弹性体,参考价约60元/公斤。耐磨、耐疲劳,软管、线缆、汽车部件。
巴陵石化(中企大厂)
YH-501,SEBS通用级,参考价约15-18元/公斤。国产主力,性价比高,塑料改性、TPE原料。
YH-792,SEBS高弹性,参考价约18-22元/公斤。高回弹,玩具、线材、密封件。
一句话总结:SBS 12-20块,SEBS 15-35块,TPEE 40-70块,TPV 20-40块。你要的是啥体系和硬度,决定了你该在哪一档选。
二、同是TPE,价差凭什么这么大
TPE的价格差,主要藏在四个地方。
第一,体系不同。SBS最便宜,SEBS贵一点,TPEE更贵,TPV最贵。体系决定了耐温、耐老化、耐油性能,也决定了价格。
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、耐油、耐老化、食品级——这些都要加钱。你买的不是纯TPE,是加了料的TPE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SEBS,科腾比巴陵石化贵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十二块的,然后做出来的制品回弹不够、耐老化差、客户退货,一次损失够买半年的好料。
TPE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SBS当SEBS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12块,做出来次品率5%;B料单价18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、要耐油又要耐老化、要食品级又要低成本——那不是TPE的问题,是你需要的不是标准TPE,是改性TPE。
这时候可以看看宁波科隆新材目前在做的高性能改性TPE方案,SEBS基、阻燃、耐油、耐老化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TPE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,TPE行情一天一个样,原油、苯乙烯、丁二烯、汇率都在动。
如果你需要科腾、李长荣、杜邦、巴陵石化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TPE这事儿,十二的和六十的,差的不是四十八。
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 TPE per kilogram?
TPE 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.
TPE
G1651, approx. CNY 45/kg. aging-resistant; plastics modification; toys.
G1653V, approx. CNY 32-35/kg. aging-resistant; eco-friendly; medical devices.
D1155, approx. CNY 32-33/kg. adhesives.
TPE
7550, approx. CNY 17-18/kg.
7551, approx. CNY 18-20/kg. toys; seals.
DuPont
Hytrel 5556, approx. CNY 60/kg. wear-resistant; fatigue-resistant; automotive parts.
TPE
YH-501, approx. CNY 15-18/kg. plastics modification.
YH-792, approx. CNY 18-22/kg. toys; seals.
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 TPE, you need a modified compound. Ningbo Kolong New Materials is developing high-performance modified TPE solutions covering glass-fiber reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified TPE 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; TPE 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.
