PA/PPE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PPE比例还多。有人说我买的二十的旭化成A0210用得挺好，有人说我买的六十的基础创新GTX810才叫高端。到底差在哪？
说实话，问PA/PPE多少钱一公斤的人，大概率还没搞懂PA/PPE这东西不是一个料——通用级、玻纤增强级、耐高温级、耐化学级、低翘曲级，每个分支价格都不一样。你拿通用级的价和玻纤增强比，那不叫比价，叫被忽悠。
PA/PPE就是聚酰胺/聚苯醚合金（PPE=PPO），结合了PA的耐化学性和PPE的耐热性、尺寸稳定性，常用于汽车外饰、电子电器、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。
基础创新塑料（SABIC，美国）
NORYL GTX810-1710 GF10，10%玻纤增强耐高温抗化学，参考价约60元/公斤。汽车部件、结构件、高端应用。
NORYL GTX820，玻纤增强耐高温，参考价约23.75元/公斤。汽车部件、电子电器。
NORYL GTX910，抗化学尺寸稳定，参考价约25-40元/公斤。汽车部件、电子电器、家电外壳。
旭化成（Asahi Kasei，日本）
XYRON AG213，30%玻纤增强，参考价约25-40元/公斤。汽车、电子、结构件。
XYRON A0210，低翘曲高流动耐化学，参考价约25.2元/公斤。汽车内饰、电子电器。
XYRON AG511，玻纤增强，参考价约20.8元/公斤。汽车、电子、通用应用。
国产PA/PPE（中企大厂）
国产通用级，参考价约15-28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18-35元/公斤。结构件、汽车、电子。
一句话总结：国产通用15-28块，国产玻纤增强18-35块，进口通用20-40块，进口玻纤增强/高端23-60块。你要的是啥PPE比例和性能，决定了你该在哪一档选。
二、同是PA/PPE，价差凭什么这么大
PA/PPE的价格差，主要藏在四个地方。
第一，PPE比例不同。PPE比例20%左右便宜，比例50%以上耐热好但贵。PPE比例越高，耐热性和尺寸稳定性越好，但加工越难。
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，耐化学等级不同。通用级便宜，高耐化学级贵。高耐化学需要特殊配方，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。同样是玻纤增强，基础创新比国产贵30-50%，贵的是品控和研发。
三、采购避坑：别让PPE比例骗了你
我见过太多采购，比价比到最后选了最便宜的十五的，然后做出来的制品耐热不够、翘曲、客户退货，一次损失够买半年的好料。
PA/PPE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，拿到料先测热变形温度和熔指，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PA当PA/PPE卖，拿低PPE比例当高比例卖。要COA、要PPE比例检测、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15块，做出来制品次品率5%；B料单价28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——比如要耐化学又要高耐热、要增强又要低翘曲、要低成本又要阻燃——那不是PA/PPE的问题，是你需要的不是标准PA/PPE，是改性PA/PPE。
这时候可以看看宁波科隆新材目前在做的高性能改性PA/PPE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PA/PPE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，PA/PPE行情一天一个样，己内酰胺、己二胺、聚苯醚、玻纤、汇率都在动。
如果你需要基础创新塑料、旭化成、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PA/PPE这事儿，十五的和六十的，差的不是四十五。
单价是门槛，选对PPE比例和性能才是底线。别让报价单上的数字迷惑了你——你买的不是一公斤塑料，是一公斤能做出耐热汽车外饰的方案。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 PA/PPE per kilogram?
PA/PPE is not one material: GF-reinforced, and each carries a different price.
1. Mainstream grade quotes (imported + domestic) — recent market references; live prices subject to same-day inquiry.

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) 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 PA/PPE, you need a modified compound. Ningbo Kolong New Materials is developing high-performance modified PA/PPE solutions covering glass-fiber reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified PA/PPE 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; PA/PPE 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.
