TSC多少钱一公斤？
这个问题一搜，从二十块一公斤到六十块一公斤，报价差得比交联度还多。有人说我买的二十的国产通用用得挺好，有人说我买的六十的进口高弹性才叫高端。到底差在哪？
说实话，问TSC多少钱一公斤的人，大概率还没搞懂TSC这东西不是一个料——通用级、高弹性级、耐油级、耐热级、医用级，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。
TSC就是热塑性硫化橡胶，由橡胶相和塑料相动态硫化制得，高弹性、可回收、易加工，常用于汽车密封、电线电缆、工业制品、消费电子、医疗。
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TSC（外企大厂）
通用级，参考价约30-45元/公斤。汽车密封、电线电缆、工业制品。
高弹性级，参考价约40-55元/公斤。高端密封、消费电子、特殊应用。
耐油级，参考价约45-60元/公斤。工业制品、汽车、特殊应用。
国产TSC（中企大厂）
通用级，参考价约20-32元/公斤。性价比高，汽车密封、电线电缆、工业制品。
高弹性级，参考价约28-42元/公斤。高端密封、消费电子、特殊应用。
耐热级，参考价约30-48元/公斤。高温应用、汽车、工业机械。
一句话总结：国产通用20-32块，国产高弹性/耐热28-48块，进口通用30-45块，进口高弹性/耐油40-60块。你要的是啥交联度和性能，决定了你该在哪一档选。
二、同是TSC，价差凭什么这么大
TSC的价格差，主要藏在四个地方。
第一，交联度不同。低交联便宜，高交联贵。交联度越高，弹性和耐热性越好，但价格更高。
第二，弹性等级不同。通用级便宜，高弹性级贵。高弹性需要特殊橡胶相，价格更高。
第三，耐油等级不同。通用级便宜，耐油级贵。耐油需要特殊配方，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：别让交联度骗了你
我见过太多采购，比价比到最后选了最便宜的二十的，然后做出来的制品弹性差、压缩永久变形大、客户退货，一次损失够买半年的好料。
TSC采购这行，水比你想的深。三个坑必须绕开：
第一，看硬度和压缩永久变形不看牌号。同一个牌号不同批次性能可能波动，拿到料先测硬度和压缩永久变形，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TSC卖，拿低交联当高交联卖。要COA、要交联度检测、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20块，做出来制品次品率5%；B料单价32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——比如要高弹性又要耐油、要耐热又要高流动、要低成本又要医用级——那不是TSC的问题，是你需要的不是标准TSC，是改性TSC。
这时候可以看看宁波科隆新材目前在做的高性能改性TSC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TSC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，TSC行情一天一个样，橡胶、塑料、硫化剂、交联剂、耐油剂、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TSC这事儿，二十的和六十的，差的不是四十。
单价是门槛，选对交联度和性能才是底线。别让报价单上的数字迷惑了你——你买的不是一公斤塑料，是一公斤能做出高弹性汽车密封的方案。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 TSC per kilogram?
TSC is not one material: high-elasticity, oil-resistant, heat-resistant, medical, and each carries a different price.
1. Mainstream grade quotes (imported + domestic) — recent market references; live prices subject to same-day inquiry.
Imported TSC
general-purpose, approx. CNY 30-45/kg. wire and cable.
high-elasticity, approx. CNY 40-55/kg. special applications.
oil-resistant, approx. CNY 45-60/kg. automotive; special applications.
Domestic TSC
general-purpose, approx. CNY 20-32/kg. wire and cable.
high-elasticity, approx. CNY 28-42/kg. special applications.
heat-resistant, approx. CNY 30-48/kg. automotive; industrial machinery.
2. Why prices differ so much
Four factors: (1) composition — lower levels are cheaper; higher levels give better performance but cost more. (2) grade level — premium grades need special formulations and cost more. (3) oil-resistance grade — 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 TSC, you need a modified compound. Ningbo Kolong New Materials is developing high-performance modified TSC solutions covering glass-fiber reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified TSC 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; TSC 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.
