LCP多少钱一公斤?货源参考,液晶聚合物的价格不便宜
LCP多少钱一公斤?
这个问题一搜,从三十五块一公斤到八十五块一公斤,报价差得比耐温等级还多。有人说我买的三十六块的住友E4008用得挺好,有人说我买的八十五块的宝理C130才叫高性能。到底差在哪?
说实话,问LCP多少钱一公斤的人,大概率还没搞懂LCP这东西不是一个料——通用级、耐高温级、高流动级、玻纤增强级、低翘曲级,每个分支价格都不一样。你拿通用级的价和耐高温级比,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。
宝理(Polyplastics,日本)
E130I,通用级30%玻纤,参考价约56元/公斤。Laperos系列,耐高温、高流动,电子连接器。
E471I,低翘曲级,参考价约50-60元/公斤。尺寸稳定,精密电子部件。
C130,耐高温加纤阻燃,参考价约85元/公斤。防辐射,高端特种工程塑料。
A130,耐化学级,参考价约50-60元/公斤。化学腐蚀环境。
住友化学(Sumitomo,日本)
E4008MR,增强级阻燃,参考价约35-71元/公斤。SUMIKASUPER系列,高温连接器。
E6008,高强度级,参考价约62-63元/公斤。高强度,结构件。
E6810,通用级,参考价约35-36元/公斤。性价比高,通用电子。
塞拉尼斯(Celanese,美国)
6130L,耐磨改性,参考价约50-70元/公斤。Vectra/Zenite系列,打印机齿轮、滑动件。
6130LX,通用级,参考价约55-70元/公斤。汽车、电子、医疗。
沃特股份(中企大厂)
沃特LCP通用级,参考价约30-50元/公斤。国产主力,性价比高,电子连接器、5G部件。
沃特LCP耐高温级,参考价约45-65元/公斤。高端应用。
一句话总结:通用级30-50块,增强阻燃35-60块,耐高温/低翘曲50-70块,高端特种65-90块。你要的是啥耐温和流动,决定了你该在哪一档选。
二、同是LCP,价差凭什么这么大
LCP的价格差,主要藏在四个地方。
第一,耐温等级不同。通用级耐温200℃左右便宜,耐高温级耐温260℃以上贵。耐温是LCP的核心指标,每升一档价格都要加。
第二,玻纤含量不同。纯树脂便宜,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。
第三,流动性不同。高流动适合薄壁精密注塑,加工窗口宽,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。同样是通用级,宝理比沃特贵30-50%,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块的,然后做出来的制品耐温不够、翘曲变形、客户退货,一次损失够买半年的好料。
LCP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PPS当LCP卖,拿通用级当耐高温级卖。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30块,做出来次品率5%;B料单价60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——比如要阻燃又要超高流动、要增强又要低翘曲、要耐高温又要低成本——那不是LCP的问题,是你需要的不是标准LCP,是改性LCP。
这时候可以看看宁波科隆新材目前在做的高性能改性LCP方案,玻纤增强、低翘曲、高流动、耐高温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LCP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,LCP行情一天一个样,原油、芳香族二酸、汇率都在动。
如果你需要宝理、住友、塞拉尼斯、沃特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LCP这事儿,三十的和八十五的,差的不是五十五。
单价是门槛,选对耐温等级和流动性才是底线。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 LCP per kilogram? Source reference — liquid crystal polymer is not cheap
How much is LCP per kilogram?
Quotes range from CNY 35/kg to CNY 85/kg. LCP (liquid crystal polymer) is not one material: general, high-temperature, high-flow, glass-fiber-reinforced and low-warpage grades each carry a different price.
1. Mainstream grade quotes (imported + domestic) — recent market references; live prices subject to same-day inquiry.
Polyplastics (Japan)
E130I, general grade, 30% glass fiber, approx. CNY 56/kg. Laperos series; high temperature, high flow; electronic connectors.
E471I, low-warpage grade, approx. CNY 50-60/kg. Dimensional stability; precision electronic parts.
C130, high-temperature, reinforced, flame-retardant, approx. CNY 85/kg. Radiation-resistant; premium specialty engineering plastic.
A130, chemical-resistant grade, approx. CNY 50-60/kg. Corrosive environments.
Sumitomo Chemical (Japan)
E4008MR, reinforced, flame-retardant, approx. CNY 35-71/kg. SUMIKASUPER series; high-temperature connectors.
E6008, high-strength grade, approx. CNY 62-63/kg. High strength; structural parts.
E6810, general-purpose, approx. CNY 35-36/kg. Cost-effective; general electronics.
Celanese (USA)
6130L, wear-modified, approx. CNY 50-70/kg. Vectra/Zenite series; printer gears, sliding parts.
6130LX, general-purpose, approx. CNY 55-70/kg. Automotive, electronics, medical.
Wote (Chinese major)
Wote LCP general-purpose, approx. CNY 30-50/kg. Domestic workhorse; cost-effective; electronic connectors, 5G parts.
Wote LCP high-temperature grade, approx. CNY 45-65/kg. Premium applications.
In short: general CNY 30-50, reinforced/flame-retardant CNY 35-60, high-temperature/low-warpage CNY 50-70, premium specialty CNY 65-90.
2. Why prices differ so much
Four factors: (1) Temperature grade — general grades withstand about 200°C and are cheap; high-temperature grades above 260°C cost more; temperature is LCP's core metric. (2) Glass-fiber content — more fiber means higher strength and a higher price. (3) Flow — high flow suits thin-wall precision molding with a wide processing window, at a higher price. (4) Brand and origin — for the same general grade, Polyplastics costs 30-50% more than Wote, paying for quality control and R&D.
3. Procurement pitfalls
The cheapest material often fails on temperature resistance or warps, 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 PPS as LCP or general as high-temperature; demand the COA, a datasheet and original packaging. Third, calculate total cost: A at CNY 30/kg with a 5% defect rate vs. B at CNY 60/kg with 1% — B is cheaper per part.
4. Standard grades not enough? Consider modified compounds
If you need flame retardancy AND ultra-high flow, reinforcement AND low warpage — you need modified LCP. Ningbo Kolong New Materials is developing high-performance modified LCP grades covering GF reinforcement, low warpage, high flow and high temperature. Message us for a modified LCP 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
LCP prices change daily — crude oil, aromatic diacids and exchange rates all move. Message us for same-day quotes on specific grades from Polyplastics, Sumitomo, Celanese or Wote; real numbers.
Final words
The gap between CNY 30 and CNY 85 is not CNY 55. Unit price is the threshold; choosing the right temperature grade and flow is the baseline. Do the math per part, add rejected-goods loss, and you will know who is truly cheap.
