UHMWPE多少钱一公斤?
这个问题一搜,从二十四块一公斤到一百七十块一公斤,报价差得比分子量还多。有人说我买的二十四的国产通用用得挺好,有人说我买的一百七的三井XM220才叫高端。到底差在哪?
说实话,问UHMWPE多少钱一公斤的人,大概率还没搞懂UHMWPE这东西不是一个料——通用注塑级、挤出级、粉末级、超细粉、纤维级,每个分支价格都不一样。你拿通用颗粒的价和超细粉比,那不叫比价,叫被忽悠。
UHMWPE就是超高分子量聚乙烯,分子量150万以上,耐磨、耐冲击、自润滑,常用于齿轮、轴承、人工关节、防弹衣、滤材。
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。
泰科纳/塞拉尼斯(Ticona/Celanese,美国)
GUR 5113,超高抗冲击耐磨,参考价约60元/公斤。齿轮、轴承、通用注塑。
GUR 4150-3,细颗粒粉末,参考价约60-80元/公斤。挤出、模压、通用制品。
GUR 1020,通用级,参考价约50-70元/公斤。通用注塑、挤出。
三井化学(Mitsui,日本)
L4000,通用注塑级,参考价约125元/公斤。齿轮、汽车内部零件、轴承。
XM220,低摩擦高抗冲耐磨粉末,参考价约29-62-170元/公斤(不同渠道差异大)。过滤器、高端应用。
XM-200U,超细粉,参考价约100元/公斤。高端粉末、特殊应用。
LS4140,热塑性工程原料,参考价约80-120元/公斤。通用注塑、挤出。
240M/240S/145M/030S,通用系列,参考价约60-100元/公斤。通用注塑、挤出。
大韩油化(UHMWPE,韩国)
VH035,特高分子量,参考价约70-100元/公斤。通用注塑、挤出。
国产UHMWPE(中石化/燕山石化等中企)
国产通用颗粒,参考价约24-26元/公斤。性价比高,通用注塑、挤出。
国产粉末级,参考价约30-50元/公斤。模压、烧结、滤材。
一句话总结:国产通用24-50块,进口通用50-100块,高端粉末/超细粉100-170块。你要的是啥分子量和形态,决定了你该在哪一档选。
二、同是UHMWPE,价差凭什么这么大
UHMWPE的价格差,主要藏在四个地方。
第一,分子量不同。分子量150万便宜,300万以上贵,600万以上更贵。分子量越高,耐磨和抗冲越好,但加工越难。
第二,形态不同。颗粒便宜,粉末适中,超细粉贵。不同形态对应不同加工方式,超细粉用于高端涂层和滤材。
第三,纯度不同。工业级纯度适中价格便宜,医疗级/食品级纯度高价格贵。人工关节必须医疗级。
第四,品牌和产地。进口溢价高但批次稳定,国产性价比高但高端牌号少。同样是通用级,三井比国产贵3-5倍,贵的是品控和研发。
三、采购避坑:别让分子量骗了你
我见过太多采购,比价比到最后选了最便宜的二十四的,然后做出来的齿轮不耐磨、轴承寿命短、客户退货,一次损失够买半年的好料。
UHMWPE采购这行,水比你想的深。三个坑必须绕开:
第一,看分子量和熔指不看牌号。同一个牌号不同批次性能可能波动,拿到料先测分子量和熔指,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HDPE当UHMWPE卖,拿低分子量当高分子量卖。要COA、要分子量检测、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24块,做出来齿轮寿命1000小时;B料单价60块,寿命5000小时。算到每个零件上,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——比如要导电又要耐磨、要增强又要自润滑、要低成本又要医疗级——那不是UHMWPE的问题,是你需要的不是标准UHMWPE,是改性UHMWPE。
这时候可以看看宁波科隆新材目前在做的高性能改性UHMWPE方案,玻纤增强、导电、耐磨、耐候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UHMWPE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,UHMWPE行情一天一个样,乙烯、催化剂、汇率都在动。
如果你需要泰科纳、三井、大韩油化、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UHMWPE这事儿,二十四的和一百七的,差的不是一百四十六。
单价是门槛,选对分子量和形态才是底线。别让报价单上的数字迷惑了你——你买的不是一公斤塑料,是一公斤能做出耐磨零件的方案。把账算到每个零件上,再加上寿命和退货损失,你才知道谁真便宜谁真贵。

How much is UHMWPE per kilogram?
UHMWPE is not one material: extrusion, powder, and each carries a different price.

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