POM多少钱一公斤?货源参考,赛钢料的水比你想的深
POM多少钱一公斤?
这个问题一搜,从十一块一公斤到一百五十五块一公斤,报价差得比耐磨等级还多。有人说我买的十三块的云天化M90用得挺好,有人说我买的二十六块的杜邦100P才叫耐疲劳。到底差在哪?
说实话,问POM多少钱一公斤的人,大概率还没搞懂POM这东西不是一个料——均聚、共聚、玻纤增强、耐磨(加PTFE/硅油)、食品级,每个分支价格都不一样。你拿共聚的价和均聚耐磨级比,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)
100P,均聚高韧性,参考价约26-27元/公斤。Delrin系列,高强度耐疲劳,机械结构件、齿轮。
500P,均聚通用级,参考价约20-25元/公斤。中粘度,通用注塑、齿轮、轴承。
500AF,均聚加20%PTFE,参考价约155元/公斤。超高耐磨,精密齿轮、轴承。
塞拉尼斯(Celanese,原泰科纳)
C9021,共聚通用级,参考价约12-13元/公斤。Hostaform系列,高流动,通用注塑。
GC20,共聚20%玻纤增强,参考价约23-38元/公斤。高强度,汽车部件、电子结构件。
宝理(Polyplastics)
M90-44,共聚通用级,参考价约13-16元/公斤。Duranex系列,中粘度,通用注塑、齿轮。
M270,共聚高流动,参考价约15-18元/公斤。薄壁制品、复杂结构件。
云天化(中企大厂)
M90,共聚通用级,参考价约11-14元/公斤。国产主力,性价比高,通用注塑、齿轮。
M25,共聚高粘度,参考价约12-15元/公斤。挤出级,棒材、板材。
一句话总结:共聚通用11-16块,均聚通用20-27块,玻纤增强20-40块,耐磨/特殊级40-160块。你要的是啥聚合类型和功能,决定了你该在哪一档选。
二、同是POM,价差凭什么这么大
POM的价格差,主要藏在四个地方。
第一,聚合类型不同。共聚POM便宜,均聚POM贵。均聚结晶度高、强度好、耐疲劳,但热稳定性差;共聚热稳定好、易加工,但强度略低。
第二,功能改性不同。玻纤增强、耐磨(加PTFE/硅油/二硫化钼)、食品级——这些都要加钱。加PTFE的耐磨级比普通级贵好几倍。
第三,流动性不同。高流动适合薄壁注塑,加工效率高,价格也贵;通用流动价格适中。
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。同样是均聚通用级,杜邦比云天华贵50-100%,贵的是品控和研发。
三、采购避坑:别让聚合类型骗了你
我见过太多采购,比价比到最后选了最便宜的十一块的,然后做出来的制品耐磨不够、热分解、客户退货,一次损失够买半年的好料。
POM采购这行,水比你想的深。三个坑必须绕开:
第一,看熔指和密度不看牌号。同一个牌号不同批次性能可能波动,拿到料先测熔指和密度,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。有些贸易商拿共聚当均聚卖,拿普通级当耐磨级卖。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11块,做出来次品率5%;B料单价16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——比如要耐磨又要高流动、要增强又要食品级、要低成本又要高性能——那不是POM的问题,是你需要的不是标准POM,是改性POM。
这时候可以看看宁波科隆新材目前在做的高性能改性POM方案,玻纤增强、耐磨、增韧、抗静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POM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,POM行情一天一个样,原油、甲醛、三聚甲醛、汇率都在动。
如果你需要杜邦、塞拉尼斯、宝理、云天化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POM这事儿,十一的和一百五十五的,差的不是一百四十四。
单价是门槛,选对聚合类型和功能才是底线。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 POM per kilogram?
POM is not one material: food-grade, and each carries a different price.
1. Mainstream grade quotes (imported + domestic) — recent market references; live prices subject to same-day inquiry.
DuPont
100P, approx. CNY 26-27/kg. high-strength fatigue-resistant; gears.

2. Why prices differ so much
Four factors: (1) composition — lower levels are cheaper; higher levels give better performance but cost more. (2) functional modification — premium grades need special formulations and cost more. (3) flow — 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 melt flow index and density 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 POM, you need a modified compound. Ningbo Kolong New Materials is developing high-performance modified POM solutions covering glass-fiber reinforcement, flame retardancy, weatherability and conductivity. Message us for a modified POM 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; POM 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.
