ETFE多少钱一公斤？
这个问题一搜，从一百一十二块一公斤到三百九十九块一公斤，报价差得比氟含量还多。有人说我买的一百一十二的杜邦HT-2004用得挺好，有人说我买的三百九十九的大金EC-6510才叫高端喷涂粉。到底差在哪？
说实话，问ETFE多少钱一公斤的人，大概率还没搞懂ETFE这东西不是一个料——注塑级、挤出级、粉末涂料级、薄膜级、色母粒级，每个分支价格都不一样。你拿注塑级的价和喷涂粉比，那不叫比价，叫被忽悠。
ETFE就是乙烯-四氟乙烯共聚物，氟塑料里的"塑料王"之一，耐化学、耐候、绝缘，常用于化工防腐、建筑膜结构、电线电缆、半导体。
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/科慕（DuPont/Chemours，美国）
Tefzel 200，通用注塑级，参考价约150元/公斤。通用注塑、挤出、防腐。
HT-2004，耐化学耐磨耐腐蚀电气电子，参考价约112元/公斤。电气/电子应用、连接器。
HT-2185，耐水解高抗冲，参考价约121元/公斤。高端应用、耐水解。
HT-2170，挤出级阀门电线，参考价约120-150元/公斤。挤出、阀门、电线电缆。
大金（Daikin，日本）
Neoflon EC-6510，静电喷涂粉厚喷，参考价约399元/公斤。粉末涂料、防腐涂层。
Neoflon EC6515/EC-6519，粉末涂料级，参考价约198元/公斤。电缆、管材、粉末涂料。
Neoflon F-40/EC-6519，乙烯-四氟乙烯共聚物，参考价约250元/公斤。通用注塑、挤出。
Neoflon EP620，抗溶剂衬里管件，参考价约219元/公斤。化工防腐、衬里。
Neoflon RP-5000，耐化学腐蚀粘结性好多层薄膜，参考价约162元/公斤。多层薄膜、食品包装。
Neoflon EP-521，薄膜级，参考价约160-200元/公斤。薄膜、建筑膜结构。
旭硝子/AGC（日本）
Fluon C-55AXP，工业应用级，参考价约200-300元/公斤。通用注塑、挤出。
Fluon C-88AP/C-88AXP，高端级，参考价约230-340元/公斤。高端应用、特殊制品。
国产ETFE（巨化/三爱富/敬信等中企）
国产ETFE色母粒，耐高温抗紫外线，参考价约210-270元/公斤（30-38美元）。挤出、注塑、线缆护套。
国产通用级，参考价约150-250元/公斤。性价比高，通用注塑、挤出。
一句话总结：进口注塑/挤出112-150块，进口薄膜/衬里160-220块，进口粉末涂料198-399块，国产通用150-270块。你要的是啥氟含量和形态，决定了你该在哪一档选。
二、同是ETFE，价差凭什么这么大
ETFE的价格差，主要藏在四个地方。
第一，形态不同。颗粒便宜，粉末适中，超细喷涂粉贵。不同形态对应不同加工方式，喷涂粉用于防腐涂层。
第二，氟含量不同。氟含量50%左右便宜，含量60%以上耐化学好但贵。氟含量越高，耐化学和耐候越好。
第三，用途不同。通用注塑便宜，挤出/薄膜适中，粉末涂料/半导体级贵。特殊用途需要特殊配方。
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起步晚。同样是注塑级，大金比国产贵30-50%，贵的是品控和研发。
三、采购避坑：别让氟含量骗了你
我见过太多采购，比价比到最后选了最便宜的一百一十二的，然后做出来的制品耐化学不够、涂层脱落、客户退货，一次损失够买半年的好料。
ETFE采购这行，水比你想的深。三个坑必须绕开：
第一，看熔指和氟含量不看牌号。同一个牌号不同批次性能可能波动，拿到料先测熔指和氟含量，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PVDF当ETFE卖，拿颗粒当粉末卖。要COA、要氟含量检测、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112块，做出来涂层寿命1年；B料单价250块，寿命5年。算到每平方米涂层上，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——比如要导电又要耐化学、要增强又要耐候、要低成本又要半导体级——那不是ETFE的问题，是你需要的不是标准ETFE，是改性ETFE。
这时候可以看看宁波科隆新材目前在做的高性能改性方案，ETFE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，ETFE行情一天一个样，四氟乙烯、乙烯、催化剂、汇率都在动。
如果你需要杜邦、大金、旭硝子、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ETFE这事儿，一百一十二的和三百九十九的，差的不是二百八十七。
单价是门槛，选对氟含量和形态才是底线。别让报价单上的数字迷惑了你——你买的不是一公斤塑料，是一公斤能做出耐化学涂层的方案。把账算到每平方米涂层上，再加上寿命和返工损失，你才知道谁真便宜谁真贵。

How much is ETFE per kilogram?
Quotes range from CNY 112/kg to CNY 399/kg. ETFE (ethylene-tetrafluoroethylene copolymer) is not one material: injection, extrusion, powder-coating, film and masterbatch grades each carry a different price. Comparing an injection-grade quote with a spray-coating powder is not price comparison; it is how you get fooled.
ETFE, one of the "king of plastics" fluoropolymers, offers chemical resistance, weatherability and insulation, and is used in chemical anti-corrosion, architectural membrane structures, wire and cable, and semiconductors.
1. Mainstream grade quotes (imported + domestic) — recent market references; live prices subject to same-day inquiry.
DuPont/Chemours (USA)
Tefzel 200, general injection grade, approx. CNY 150/kg. General injection, extrusion, anti-corrosion.
HT-2004, chemical-, wear- and corrosion-resistant for electrical/electronics, approx. CNY 112/kg. Electrical/electronic applications, connectors.
HT-2185, hydrolysis-resistant, high impact, approx. CNY 121/kg. Premium applications.
HT-2170, extrusion grade for valves and wire, approx. CNY 120-150/kg. Extrusion, valves, wire and cable.
Daikin (Japan)
Neoflon EC-6510, electrostatic spray powder, thick coating, approx. CNY 399/kg. Powder coating, anti-corrosion coatings.
Neoflon EC6515/EC-6519, powder-coating grade, approx. CNY 198/kg. Cable, pipe, powder coating.
Neoflon F-40/EC-6519, ETFE, approx. CNY 250/kg. General injection, extrusion.
Neoflon EP620, solvent-resistant lining and fittings, approx. CNY 219/kg. Chemical anti-corrosion, lining.
Neoflon RP-5000, chemical-resistant, high-adhesion multilayer film, approx. CNY 162/kg. Multilayer film, food packaging.
Neoflon EP-521, film grade, approx. CNY 160-200/kg. Film, architectural membranes.
AGC (Japan)
Fluon C-55AXP, industrial grade, approx. CNY 200-300/kg. General injection, extrusion.
Fluon C-88AP/C-88AXP, premium grade, approx. CNY 230-340/kg. Premium applications, special products.
Domestic ETFE (Juhua, 3F, Jingxin and other Chinese producers)
Domestic ETFE masterbatch, high-temperature, UV-resistant, approx. CNY 210-270/kg (USD 30-38). Extrusion, injection, cable jacketing.
Domestic general-purpose, approx. CNY 150-250/kg. Cost-effective; general injection, extrusion.
In short: imported injection/extrusion CNY 112-150, imported film/liner CNY 160-220, imported powder coating CNY 198-399, domestic general-purpose CNY 150-270.
2. Why prices differ so much
Four factors: (1) Form — pellets are cheap, powders mid-range, ultra-fine spray powders expensive; each form matches a different process. (2) Fluorine content — higher content means better chemical and weather resistance but a higher price. (3) Application — general injection is cheap; powder-coating/semiconductor grades are expensive. (4) Brand and origin — for the same injection grade, Daikin costs 30-50% more than domestic, paying for quality control and R&D.
3. Procurement pitfalls
The cheapest material often fails on chemical resistance or coating adhesion, causing returns. Three traps to avoid:
First, test melt flow index and fluorine content against the COA instead of trusting the grade name. Second, watch for substitution: some traders sell PVDF as ETFE or pellets as powder; demand the COA, a fluorine-content test and original packaging. Third, calculate total cost per square meter of coating: A at CNY 112/kg with a 1-year coating life vs. B at CNY 250/kg with 5 years — B is cheaper.
4. Standard grades not enough? Consider modified compounds
If you need conductivity AND chemical resistance, reinforcement AND weatherability — you need modified ETFE. Ningbo Kolong New Materials is developing high-performance modified ETFE grades covering reinforcement, conductivity, wear resistance and weatherability. Message us for a 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
ETFE prices change daily — tetrafluoroethylene, ethylene, catalysts and exchange rates all move. Message us for same-day quotes on specific grades from DuPont, Daikin, AGC or domestic producers; real numbers.
Final words
The gap between CNY 112 and CNY 399 is not CNY 287. Unit price is the threshold; choosing the right fluorine content and form is the baseline. You are buying a solution for making chemical-resistant coatings. Add coating life and rework loss into the per-square-meter math, and you will know who is truly cheap.
