PPA多少钱一公斤?价差金句,高温尼龙不是普通尼龙加价卖
PPA多少钱一公斤?
这个问题一搜,从十七块一公斤到六十五块一公斤,报价差得比耐温等级还多。有人说我买的四十八块的杜邦HTN用得挺好,有人说我买的五十块的苏威AS-4133才叫耐高温。到底差在哪?
说实话,问PPA多少钱一公斤的人,大概率还没搞懂PPA这东西不是一个料——纯树脂、玻纤增强、阻燃、耐高温、高CTI,每个分支价格都不一样。你拿纯树脂的价和玻纤增强阻燃比,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。
杜邦(DuPont)
HTN51G35HSL,35%玻纤增强热稳定,参考价约48-65元/公斤。Zytel系列,耐高温、高刚性,汽车传感器、电子连接器。
HTNFR52G30BL,30%玻纤增强无卤阻燃,参考价约48-50元/公斤。UL94 V-0,汽车点火系统、电子插座。
苏威(Solvay,原阿莫科)
AS-4133-BK,耐高温抗蠕变,参考价约48-52元/公斤。Amodel系列,尺寸稳定,汽车、电子元件。
AS-1240,40%玻纤增强,参考价约45-50元/公斤。高强度,注塑件、结构件。
HFFR-4133,无卤阻燃,参考价约50元/公斤。阻燃耐高温,汽车零部件。
巴斯夫(BASF)
Ultramid T系列,PPA通用级,参考价约40-55元/公斤。耐高温、耐化学,汽车、电子。
金发科技(中企大厂)
金发PPA玻纤增强,参考价约35-45元/公斤。国产主力,性价比高,汽车、电子部件。
金发PPA阻燃级,参考价约40-50元/公斤。无卤阻燃,电子电器。
一句话总结:纯树脂30-40块,玻纤增强40-55块,阻燃级45-60块,特殊级50-70块。你要的是啥填充和耐温,决定了你该在哪一档选。
二、同是PPA,价差凭什么这么大
PPA的价格差,主要藏在四个地方。
第一,玻纤含量不同。纯树脂便宜,30%玻纤贵一点,35%以上玻纤更贵。玻纤加得越多,强度和耐温越高,价格也越高。
第二,阻燃等级不同。纯树脂便宜,无卤阻燃V0贵很多。阻燃剂是PPA里最贵的添加剂之一。
第三,耐温等级不同。HDT越高,价格越贵。高温尼龙的核心价值就是耐温,耐温每升一档,价格都要加。
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。同样是玻纤增强,杜邦比金发贵20-30%,贵的是品控和研发。
三、采购避坑:别让耐温等级骗了你
我见过太多采购,比价比到最后选了最便宜的三十多块的,然后做出来的制品耐温不够、尺寸不稳、客户退货,一次损失够买半年的好料。
PPA采购这行,水比你想的深。三个坑必须绕开:
第一,看灰分和热变形温度不看牌号。同一个牌号不同批次玻纤含量可能波动,拿到料先测灰分和HDT,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PA66当PPA卖,拿纯树脂当增强级卖。要COA、要物性报告、要UL黄卡,三证合一才敢用。
第三,别只比单价,算综合成本。A料单价35块,做出来次品率5%;B料单价50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——比如要阻燃又要高流动、要增强又要增韧、要高CTI又要低成本——那不是PPA的问题,是你需要的不是标准PPA,是改性PPA。
这时候可以看看宁波科隆新材目前在做的高性能改性PPA方案,玻纤增强、无卤阻燃、增韧、高CTI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PPA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,PPA行情一天一个样,原油、芳香族二酸、汇率都在动。
如果你需要杜邦、苏威、巴斯夫、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PPA这事儿,三十多的和六十多的,差的不是三十。
单价是门槛,选对玻纤含量和耐温等级才是底线。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 PPA per kilogram?
PPA is not one material: flame-retardant, high-temperature, and each carries a different price.
1. Mainstream grade quotes (imported + domestic) — recent market references; live prices subject to same-day inquiry.
DuPont
HTN51G35HSL, approx. CNY 48-65/kg. high-temperature; high-rigidity; electronics connectors.
HTNFR52G30BL, approx. CNY 48-50/kg.
PPA
AS-4133-BK, approx. CNY 48-52/kg. dimensional stability; automotive.
AS-1240, approx. CNY 45-50/kg. high-strength; structural parts.
HFFR-4133, approx. CNY 50/kg. flame-retardant high-temperature.
BASF
approx. CNY 40-55/kg. high-temperature; chemical-resistant; automotive; electronics.
Kingfa
approx. CNY 35-45/kg. automotive; electronic components.
approx. CNY 40-50/kg. electronics.
2. Why prices differ so much
Four factors: (1) glass-fiber content — lower levels are cheaper; higher levels give better performance but cost more. (2) flame-retardant grade — premium grades need special formulations and cost more. (3) temperature 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 PPA, you need a modified compound. Ningbo Kolong New Materials is developing high-performance modified PPA solutions covering glass-fiber reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified PPA 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; PPA 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.
