TPV多少钱一公斤？牌号对版，动态硫化的弹性体不便宜
TPV多少钱一公斤？
这个问题一搜，从二十块一公斤到四十块一公斤，报价差得比硬度还多。有人说我买的二十六块的国产用得挺好，有人说我买的四十块的埃克森美孚才叫耐老化。到底差在哪？
说实话，问TPV多少钱一公斤的人，大概率还没搞懂TPV这东西不是一个料——通用级、耐油级、耐候级、食品级、阻燃级，每个分支价格都不一样。你拿通用级的价和耐油级比，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。
埃克森美孚（ExxonMobil，原塞拉尼斯山都平）
201-73，通用级73A，参考价约30-35元/公斤。Santoprene系列，耐候、耐臭氧，汽车密封、建筑。
121-67W175，耐候级67A，参考价约31-33元/公斤。抗紫外线，户外制品、汽车外饰。
8221-65M300，通用级65A，参考价约26-30元/公斤。高流动，通用注塑、密封件。
RC8001，耐热耐油级，参考价约39-40元/公斤。耐油耐化学，汽车油管、工业密封。
三井化学（Mitsui）
9070BKS，通用级70A，参考价约20-25元/公斤。Milastomer系列，性价比高，汽车内饰、密封件。
W800BC，耐候级80A，参考价约22-28元/公斤。抗紫外线，户外制品。
道康宁（Dow Corning，现陶氏）
道康宁TPV通用级，参考价约25-35元/公斤。耐候、耐臭氧，高端密封、建筑。
道恩股份（中企大厂）
道恩TPV通用级，参考价约20-26元/公斤。国产主力，性价比高，汽车密封、建筑、日用品。
道恩TPV耐油级，参考价约25-32元/公斤。耐油耐化学，工业密封、油管。
一句话总结：通用级20-30块，耐候级25-35块，耐油级30-40块，食品/阻燃级35-50块。你要的是啥硬度和功能，决定了你该在哪一档选。
二、同是TPV，价差凭什么这么大
TPV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。
第二，功能改性不同。耐油、耐候、阻燃、食品级——这些都要加钱。耐油级比通用级贵30-50%。
第三，硫化程度不同。动态硫化程度越高，弹性和耐温越好，价格也越贵。
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。同样是通用级，埃克森美孚比道恩贵30-50%，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，然后做出来的制品弹性不够、耐油差、客户退货，一次损失够买半年的好料。
TPV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当TPV卖，拿通用级当耐油级卖。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、要耐油又要耐候、要食品级又要低成本——那不是TPV的问题，是你需要的不是标准TPV，是改性TPV。
这时候可以看看宁波科隆新材目前在做的高性能改性TPV方案，阻燃、耐油、耐候、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TPV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，TPV行情一天一个样，原油、EPDM、聚丙烯、汇率都在动。
如果你需要埃克森美孚、三井化学、道康宁、道恩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TPV这事儿，二十的和四十的，差的不是二十。
单价是门槛，选对硬度和功能才是底线。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 TPV per kilogram?
TPV is not one material: oil-resistant, weatherability, food-grade, flame-retardant, and each carries a different price.

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