PPS/PA多少钱一公斤?
这个问题一搜,从四十块一公斤到一百块一公斤,报价差得比PPS比例还多。有人说我买的四十的国产通用用得挺好,有人说我买的一百的进口高耐热才叫高端。到底差在哪?
说实话,问PPS/PA多少钱一公斤的人,大概率还没搞懂PPS/PA这东西不是一个料——通用级、高耐热级、玻纤增强级、耐磨级、阻燃级,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。
PPS/PA就是聚苯硫醚/尼龙合金,结合了PPS的耐热和PA的韧性,常用于汽车发动机周边、电子电器、工业机械、结构件、耐磨件。
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PPS/PA(外企大厂)
通用级,参考价约60-85元/公斤。汽车发动机周边、电子电器、工业机械。
高耐热级,参考价约70-95元/公斤。工业机械、结构件、高温应用。
玻纤增强级,参考价约75-100元/公斤。结构件、汽车、工业机械。
国产PPS/PA(中企大厂)
通用级,参考价约40-65元/公斤。性价比高,汽车发动机周边、电子电器、工业机械。
高耐热级,参考价约48-75元/公斤。工业机械、结构件、高温应用。
玻纤增强级,参考价约55-85元/公斤。结构件、汽车、工业机械。
一句话总结:国产通用40-65块,国产高耐热/玻纤增强48-85块,进口通用60-85块,进口高耐热/玻纤增强70-100块。你要的是啥PPS比例和性能,决定了你该在哪一档选。
二、同是PPS/PA,价差凭什么这么大
PPS/PA的价格差,主要藏在四个地方。
第一,PPS比例不同。PPS比例30%左右便宜,比例60%以上高耐热但贵。PPS比例越高,耐热性和耐化学性越好,但韧性略降。
第二,耐热等级不同。通用级便宜,高耐热级贵。高耐热需要特殊配方,价格更高。
第三,增强方式不同。无筋通用便宜,玻纤增强贵。玻纤增强比无筋通用贵30-50%。
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。同样是高耐热级,进口比国产贵30-50%,贵的是品控和研发。
三、采购避坑:别让PPS比例骗了你
我见过太多采购,比价比到最后选了最便宜的四十的,然后做出来的制品耐热差、变形、客户退货,一次损失够买半年的好料。
PPS/PA采购这行,水比你想的深。三个坑必须绕开:
第一,看热变形温度和冲击强度不看牌号。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冲击强度,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PPS当PPS/PA卖,拿低PPS比例当高比例卖。要COA、要PPS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40块,做出来制品次品率5%;B料单价65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——比如要高耐热又要高韧性、要玻纤增强又要高流动、要低成本又要耐磨级——那不是PPS/PA的问题,是你需要的不是标准PPS/PA,是改性PPS/PA。
这时候可以看看宁波科隆新材目前在做的高性能改性PPS/PA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PPS/PA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,PPS/PA行情一天一个样,对二氯苯、硫化钠、己内酰胺、玻纤、阻燃剂、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PPS/PA这事儿,四十的和一百的,差的不是六十。
单价是门槛,选对PPS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,是一公斤能做出高耐热汽车发动机部件的方案。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 PPS/PA per kilogram?
PPS/PA is not one material: high-heat, GF-reinforced, wear-resistant, flame-retardant, and each carries a different price.
1. Mainstream grade quotes (imported + domestic) — recent market references; live prices subject to same-day inquiry.
Imported PPS/PA
general-purpose, approx. CNY 60-85/kg. engine compartments; electronics; industrial machinery.
high-heat, approx. CNY 70-95/kg. industrial machinery; structural parts.
GF-reinforced, approx. CNY 75-100/kg. structural parts; automotive; industrial machinery.
Domestic PPS/PA
general-purpose, approx. CNY 40-65/kg. engine compartments; electronics; industrial machinery.
high-heat, approx. CNY 48-75/kg. industrial machinery; structural parts.
GF-reinforced, approx. CNY 55-85/kg. structural parts; 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) heat grade — premium grades need special formulations and cost more. (3) reinforcement — 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 PPS/PA, you need a modified compound. Ningbo Kolong New Materials is developing high-performance modified PPS/PA solutions covering glass-fiber reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified PPS/PA 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; PPS/PA 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.
