MPPO多少钱一公斤?标准改性对比,聚苯醚的价格差在共混比
MPPO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PPO含量还多。有人说我买的二十四块的SABIC Noryl SE100用得挺好,有人说我买的五十块的Noryl GTX840才叫汽车级。到底差在哪?
说实话,问MPPO多少钱一公斤的人,大概率还没搞懂MPPO这东西不是一个料——PPO/PS合金、PPO/PA合金、玻纤增强级、阻燃级、导电级,每个分支价格都不一样。你拿PPO/PS的价和PPO/PA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。
SABIC(沙伯基础,美国)
Noryl SE100,PPO+PS通用阻燃,参考价约24元/公斤。电子电器、防火配件。
Noryl GTX840,PPE/PA 40%玻纤,参考价约40-50元/公斤。汽车引擎盖、外饰件。
Noryl PX1630,30%玻纤增强耐水解,参考价约40-60元/公斤。水处理、饮用水应用。
Noryl N1150,通用级,参考价约25-35元/公斤。连接器、汽车部件、线轴。
Noryl 115EM4,导电级,参考价约31元/公斤。导电、防静电应用。
旭化成(Asahi Kasei,日本)
Xyron系列MPPO,参考价约30-50元/公斤。汽车、电子、办公设备。
金发科技(中企大厂)
金发MPPO通用级,参考价约20-28元/公斤。国产主力,性价比高,电子电器、汽车。
金发MPPO玻纤增强级,参考价约25-35元/公斤。结构件、汽车部件。
一句话总结:通用级20-30块,阻燃级24-35块,玻纤增强30-50块,PPO/PA合金40-60块,导电/特殊级30-50块。你要的是啥合金体系和增强,决定了你该在哪一档选。
二、同是MPPO,价差凭什么这么大
MPPO的价格差,主要藏在四个地方。
第一,PPO含量不同。PPO含量越高,耐热和尺寸稳定越好,价格也越贵。高PPO含量比低含量贵30-50%。
第二,合金体系不同。PPO/PS便宜,PPO/PA贵,PPO/PBT更贵。合金体系决定了性能和价格。
第三,玻纤含量不同。纯合金便宜,30%玻纤增强贵一点,40%以上玻纤更贵。玻纤加得越多,强度越高,价格也越高。
第四,品牌和产地。进口溢价高但批次稳定,国产性价比高但质量参差。同样是玻纤增强,SABIC比金发贵30-50%,贵的是品控和研发。
三、采购避坑:别让PPO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热不够、分层、客户退货,一次损失够买半年的好料。
MPPO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HIPS当MPPO卖,拿PPO/PS当PPO/PA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35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、要增强又要耐水解、要低成本又要高性能——那不是MPPO的问题,是你需要的不是标准MPPO,是定制改性MPPO。
这时候可以看看宁波科隆新材目前在做的高性能改性MPPO方案,玻纤增强、阻燃、耐水解、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MPPO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,MPPO行情一天一个样,原油、2,6-二甲苯酚、PS、汇率都在动。
如果你需要SABIC、旭化成、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MPPO这事儿,二十的和六十的,差的不是四十。
单价是门槛,选对合金体系和PPO含量才是底线。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 MPPO per kilogram? Standard vs. modified — the price of polyphenylene ether lies in the blend ratio
How much is MPPO per kilogram?
Quotes range from CNY 20/kg to CNY 60/kg. MPPO is not one material: PPO/PS alloy, PPO/PA alloy, glass-fiber-reinforced, flame-retardant and conductive grades each carry a different price. Comparing a PPO/PS quote with a PPO/PA one is not price comparison; it is how you get fooled.
1. Mainstream grade quotes (imported + domestic) — recent market references; live prices subject to same-day inquiry.
SABIC (USA)
Noryl SE100, PPO+PS, general flame-retardant, approx. CNY 24/kg. Electronics, fire-retardant parts.
Noryl GTX840, PPE/PA, 40% glass fiber, approx. CNY 40-50/kg. Automotive hoods, exterior parts.
Noryl PX1630, 30% GF-reinforced, hydrolysis-resistant, approx. CNY 40-60/kg. Water treatment, drinking-water applications.
Noryl N1150, general-purpose, approx. CNY 25-35/kg. Connectors, automotive parts, wire spools.
Noryl 115EM4, conductive grade, approx. CNY 31/kg. Conductive, antistatic applications.
Asahi Kasei (Japan)
Xyron series MPPO, approx. CNY 30-50/kg. Automotive, electronics, office equipment.
Kingfa (Chinese major)
Kingfa MPPO general-purpose, approx. CNY 20-28/kg. Domestic workhorse; cost-effective; electronics, automotive.
Kingfa MPPO GF-reinforced, approx. CNY 25-35/kg. Structural parts, automotive parts.
In short: general CNY 20-30, flame-retardant CNY 24-35, GF-reinforced CNY 30-50, PPO/PA alloy CNY 40-60, conductive/special CNY 30-50.
2. Why prices differ so much
Four factors: (1) PPO content — higher PPO means better heat resistance and dimensional stability but a price 30-50% higher. (2) Alloy system — PPO/PS is cheap, PPO/PA costs more, PPO/PBT costs most; the system decides performance and price. (3) Glass-fiber content — more fiber means higher strength and a higher price. (4) Brand and origin — for the same GF-reinforced grade, SABIC costs 30-50% more than Kingfa, paying for quality control and R&D.
3. Procurement pitfalls
The cheapest material often fails on heat resistance or delaminates, causing returns. Three traps to avoid:
First, test HDT and melt flow index against the COA instead of trusting the grade name. Second, watch for substitution: some traders sell HIPS as MPPO or PPO/PS as PPO/PA; demand the COA, a datasheet and original packaging. Third, calculate total cost: A at CNY 20/kg with a 5% defect rate vs. B at CNY 35/kg with 1% — B is cheaper per part.
4. Standard grades not enough? Consider custom modification
If you need flame retardancy AND high flow, reinforcement AND hydrolysis resistance — you need custom modified MPPO. Ningbo Kolong New Materials is developing high-performance modified MPPO grades covering GF reinforcement, flame retardancy, hydrolysis resistance and conductivity. Message us for a modified MPPO quote reference.
In plain terms: standard grades are a big pot of shared rice; modified compounds are a dish cooked to order.
5. Same-day quotes via message
MPPO prices change daily — crude oil, 2,6-xylenol, PS and exchange rates all move. Message us for same-day quotes on specific grades from SABIC, Asahi Kasei or Kingfa; real numbers.
Final words
The gap between CNY 20 and CNY 60 is not CNY 40. Unit price is the threshold; choosing the right alloy system and PPO content is the baseline. Do the math per part, add rejected-goods loss, and you will know who is truly cheap.
