PC/PBT多少钱一公斤？国产进口对比，合金料的价格差在配方
PC/PBT多少钱一公斤？
这个问题一搜，从二十块一公斤到三十七块一公斤，报价差得比PC含量还多。有人说我买的二十五块的金发用得挺好，有人说我买的三十三块的科思创Makroblend才叫稳定。到底差在哪？
说实话，问PC/PBT多少钱一公斤的人，大概率还没搞懂PC/PBT这东西不是一个料——通用级、耐化学级、抗UV级、玻纤增强级、阻燃级，每个分支价格都不一样。你拿通用级的价和耐化学级比，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。
科思创（Covestro，原拜耳）
Makroblend UT6005，通用级，参考价约33元/公斤。高抗冲、耐化学，汽车、电子外壳。
Makroblend UT6007，通用级，参考价约30-35元/公斤。机械、仪器仪表、汽车部件。
Makroblend S7916，低温韧性耐化学，参考价约32元/公斤。抗紫外线、阻燃、玻纤增强。
SABIC（沙伯基础）
XENOY ENH2900，通用级，参考价约25-35元/公斤。抗溶剂、抗UV、耐低温冲击，电子、个人护理。
XENOY CL100S，耐化学抗UV，参考价约30-40元/公斤。汽车外饰、户外制品。
5220UC，冲击改性耐寒，参考价约30-40元/公斤。耐应力开裂，汽车部件。
VALOX IQ507，PC+PBT合金，参考价约36-37元/公斤。充电桩、汽车外饰。
金发科技（中企大厂）
金发PC/PBT通用级，参考价约20-28元/公斤。国产主力，性价比高，汽车、电子外壳。
金发PC/PBT耐化学级，参考价约25-32元/公斤。汽车外饰、工业部件。
一句话总结：通用级20-30块，耐化学/抗UV 25-35块，玻纤增强/阻燃30-40块，高端特殊级35-45块。你要的是啥性能，决定了你该在哪一档选。
二、同是PC/PBT，价差凭什么这么大
PC/PBT的价格差，主要藏在四个地方。
第一，PC含量不同。PC含量越高，耐热和抗冲越好，价格也越贵。PC含量70%的比50%的贵不少。
第二，功能改性不同。耐化学、抗UV、阻燃、玻纤增强——这些都要加钱。耐化学级比通用级贵20-30%。
第三，相容剂不同。好的相容剂能提升合金性能，但成本也高。便宜的PC/PBT可能用低档相容剂，性能不稳定。
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，科思创比金发贵30-50%，贵的是品控和研发。
三、采购避坑：别让PC含量骗了你
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化学差、分层、客户退货，一次损失够买半年的好料。
PC/PBT采购这行，水比你想的深。三个坑必须绕开：
第一，看热变形温度和熔指不看牌号。同一个牌号不同批次性能可能波动，拿到料先测HDT和熔指，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PC/ABS当PC/PBT卖，拿通用级当耐化学级卖。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——比如要阻燃又要耐化学、要增强又要抗UV、要低成本又要高性能——那不是PC/PBT的问题，是你需要的不是标准PC/PBT，是改性PC/PBT。
这时候可以看看宁波科隆新材目前在做的高性能改性PC/PBT方案，玻纤增强、阻燃、耐化学、抗UV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PC/PBT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，PC/PBT行情一天一个样，原油、双酚A、PBT、汇率都在动。
如果你需要科思创、SABIC、金发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PC/PBT这事儿，二十的和三十七的，差的不是十七。
单价是门槛，选对PC含量和功能才是底线。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 PC/PBT per kilogram?
PC/PBT is not one material: GF-reinforced, flame-retardant, and each carries a different price.

2. Why prices differ so much
Four factors: (1) composition — 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 heat deflection temperature and melt flow index 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 PC/PBT, you need a modified compound. Ningbo Kolong New Materials is developing high-performance modified PC/PBT solutions covering glass-fiber reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified PC/PBT 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; PC/PBT 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.
