PBT/ASA多少钱一公斤？
这个问题一搜，从二十块一公斤到五十块一公斤，报价差得比ASA含量还多。有人说我买的二十的国产通用用得挺好，有人说我买的五十的巴斯夫高端才叫耐候。到底差在哪？
说实话，问PBT/ASA多少钱一公斤的人，大概率还没搞懂PBT/ASA这东西不是一个料——通用级、玻纤增强级、耐候级、阻燃级、高流动级，每个分支价格都不一样。你拿通用级的价和耐候级比，那不叫比价，叫被忽悠。
PBT/ASA就是聚对苯二甲酸丁二醇酯/丙烯腈苯乙烯丙烯酸酯合金，结合了PBT的耐热性和ASA的耐候性，常用于汽车外饰、户外电子、家电外壳、电动工具。
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，德国）
Ultradur PBT/ASA系列，通用级，参考价约28-45元/公斤。汽车外饰、户外电子、家电外壳。
Ultradur PBT/ASA玻纤增强级，参考价约32-50元/公斤。结构件、汽车、户外应用。
英力士苯领（INEOS Styrolution，德国）
PBT/ASA系列，通用级，参考价约26-42元/公斤。汽车、电子、家电。
PBT/ASA耐候级，参考价约30-48元/公斤。户外应用、汽车外饰。
国产PBT/ASA（中企大厂）
国产通用级，参考价约18-30元/公斤。性价比高，通用注塑、汽车、电子。
国产玻纤增强级，参考价约22-38元/公斤。结构件、汽车、户外应用。
国产耐候级，参考价约25-40元/公斤。户外应用、汽车外饰。
一句话总结：国产通用18-30块，国产玻纤增强22-38块，进口通用26-45块，进口玻纤增强/耐候30-50块。你要的是啥ASA含量和性能，决定了你该在哪一档选。
二、同是PBT/ASA，价差凭什么这么大
PBT/ASA的价格差，主要藏在四个地方。
第一，ASA含量不同。ASA含量20%左右便宜，含量50%以上耐候好但贵。ASA含量越高，耐候性越好，但耐热性略降。
第二，玻纤增强不同。无筋通用便宜，30%玻纤增强贵。玻纤增强比通用级贵20-30%。
第三，耐候等级不同。通用级便宜，高耐候级贵。高耐候需要特殊配方和UV稳定剂，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。同样是通用级，巴斯夫比国产贵30-50%，贵的是品控和研发。
三、采购避坑：别让ASA含量骗了你
我见过太多采购，比价比到最后选了最便宜的十八的，然后做出来的户外制品耐候差、变色、客户退货，一次损失够买半年的好料。
PBT/ASA采购这行，水比你想的深。三个坑必须绕开：
第一，看耐候等级和熔指不看牌号。同一个牌号不同批次性能可能波动，拿到料先测耐候等级和熔指，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PBT当PBT/ASA卖，拿低ASA含量当高含量卖。要COA、要ASA含量检测、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18块，做出来户外制品次品率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——比如要耐候又要高耐热、要增强又要高流动、要低成本又要阻燃——那不是PBT/ASA的问题，是你需要的不是标准PBT/ASA，是改性PBT/ASA。
这时候可以看看宁波科隆新材目前在做的高性能改性PBT/ASA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PBT/ASA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，PBT/ASA行情一天一个样，对苯二甲酸、丁二醇、ASA、玻纤、汇率都在动。
如果你需要巴斯夫、英力士苯领、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PBT/ASA这事儿，十八的和五十的，差的不是三十二。
单价是门槛，选对ASA含量和性能才是底线。别让报价单上的数字迷惑了你——你买的不是一公斤塑料，是一公斤能做出耐候汽车外饰的方案。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 PBT/ASA per kilogram?
PBT/ASA is not one material: GF-reinforced, weatherability, flame-retardant, high-flow, and each carries a different price.
1. Mainstream grade quotes (imported + domestic) — recent market references; live prices subject to same-day inquiry.
BASF
general-purpose, approx. CNY 28-45/kg. automotive exteriors; appliance housings.
approx. CNY 32-50/kg. structural parts; automotive; outdoor applications.
PBT/ASA
general-purpose, approx. CNY 26-42/kg. automotive; electronics; appliances.
approx. CNY 30-48/kg. outdoor applications; automotive exteriors.
Domestic PBT/ASA
Domestic general-purpose, approx. CNY 18-30/kg. general injection; automotive; electronics.
Domestic GF-reinforced, approx. CNY 22-38/kg. structural parts; automotive; outdoor applications.
Domestic weatherability, approx. CNY 25-40/kg. outdoor applications; automotive exteriors.
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) weatherability 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 PBT/ASA, you need a modified compound. Ningbo Kolong New Materials is developing high-performance modified PBT/ASA solutions covering glass-fiber reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified PBT/ASA 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; PBT/ASA 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.
