  • Advanced Materials Price Trend Daily — July 24, 2026: Carbon Fiber Enters Hike Cycle

    Price Trend Daily Report — July 24, 2026

    Key takeaway: Carbon fiber has entered a price-hike cycle driven by surging acrylonitrile (AN) feedstock costs — the top item to watch this week. PTFE and technical ceramic raw materials remain weak-but-stable; PEEK and PI film prices are flat with notable structural divergence.

    Price Overview

    Material Current Price Range WoW Change Trend
    PTFE resin (suspension, medium granule) RMB 30,000–35,000/t (latest quote 31,800/t) ≈0% Stable to soft
    PEEK resin Domestic neat resin RMB 200,000–400,000/t; imported RMB 800,000–1,500,000/t 0% Stable
    Carbon fiber T300(12K) RMB 90/kg; T300(24/25K) RMB 80/kg; T700(12K) RMB 140/kg +3–4% (24/25K & 48/50K tows) Rising
    PI film Electronic grade RMB 600k–3M/t; standard insulation film RMB 20–50/m² 0% Stable (high-end tight)
    Technical ceramic raw materials SiC 98-grade lump RMB 5,700/t; Si3N4 powder RMB 150–350/kg 0% Weak but stable

    Key Movements

    • Carbon fiber: large-tow grades +3–4%. T300(24/25K) and T300(48/50K) each rose RMB 3/kg this week. The core driver is persistently rising acrylonitrile prices — supply cuts in North America and the Middle East combined with resilient demand from ABS and carbon fiber in China. Jilin Chemical Fiber has announced price increases across its carbon fiber product lines. Although industry inventory remains elevated (~15,700 t), cost-push price hikes are now an established trend.
    • PTFE: consolidating sideways. Latest Shandong quote for suspension medium-granule resin is RMB 31,800/t, with the 30-day range narrowing within RMB 30,000–48,000/t. Downstream offtake is moderate; environmental production curbs provide a supply-side floor. Short-term outlook: stable.
    • PEEK: flat quotes, domestic substitution capping upside. Imported grades (Victrex, Solvay) hold at RMB 800–1,500/kg; domestic grades at RMB 200–400/kg. Lightweighting demand from robotics and eVTOL is growing ~8–10% per year, but capacity expansion by domestic producers offsets upward price momentum.

    Impact Analysis

    • Procurement costs: Carbon fiber cost pressure is likely to persist — the AN rally is hard to break near term. Composite, wind-blade and sporting-goods manufacturers should expect Q3 procurement costs to rise 3–8%. PTFE and ceramic raw materials remain buyer-friendly.
    • Supply chain: High-end PI film (electronic grade, flexible display) remains heavily import-dependent (DuPont, UBE, Kaneka, SK), with highly concentrated supply. Disruption risk outweighs price risk under geopolitical or trade friction; dual sourcing is advised for critical programs.

    Action Recommendations

    • Lock in prices: Carbon fiber (especially T300 large-tow and T700). Leading producers have initiated hikes, and once AN inventory buffers (only 3–4 months at some producers) are depleted, a second round of increases is possible. Recommend securing Q3–Q4 long-term contracts.
    • Wait and see: PTFE and technical ceramic raw materials — weak supply and demand, bottom-range consolidation. Buy as needed; no need to pre-stock.
    • Watch: Domestic PEEK substitution opportunities as local prices trend down; qualification testing of domestic high-end PI film suppliers (e.g., Rayitek, Goldenmax).

  • 2026-07-24 新材料价格趋势日报：碳纤维开启涨价周期，PTFE弱稳盘整

    2026-07-24 价格趋势日报

    核心结论：碳纤维在原料丙烯腈持续上涨推动下开启涨价周期，是本周最需关注的品类；PTFE、特种陶瓷弱稳盘整，PEEK、PI薄膜价格稳定但结构分化明显。

    价格概览表

    材料 当前价格区间 周环比 趋势
    PTFE树脂（悬浮中粒） 3.0万–3.5万元/吨（近期报价31800元/吨） ≈0% 稳中偏弱
    PEEK树脂 国产纯树脂20–40万元/吨；进口80–150万元/吨 0% 稳定
    碳纤维 T300(12K) 90元/kg；T300(24/25K) 80元/kg；T700(12K) 140元/kg +3~4%（24/25K、48/50K丝束） 上涨
    PI薄膜 电子级60万–300万元/吨；普通绝缘膜20–50元/㎡ 0% 稳定（高端偏紧）
    特种陶瓷原料 碳化硅98块5700元/吨；氮化硅粉150–350元/kg 0% 弱稳

    重点变动

    • 碳纤维：大丝束+3~4%。T300(24/25K)、T300(48/50K)本周各上涨3元/kg。核心驱动是原料丙烯腈价格持续走高——北美与中东供应减量叠加国内ABS、碳纤维需求韧性，吉林化纤已宣布上调旗下各牌号碳纤维价格。行业库存虽仍处高位（约1.57万吨），但成本推动型涨价已成趋势。
    • PTFE：持稳盘整。山东悬浮中粒最新报价31800元/吨，30日内价格区间30000–48000元/吨波动收窄。下游出货一般，环保限产对供应端形成底部支撑，短期维稳。
    • PEEK：报价平稳，国产替代压价。进口料（威格斯、苏威）维持800–1500元/kg，国产料200–400元/kg。机器人、低空飞行器轻量化需求增长约8–10%/年，但中研股份等国产扩产对冲了涨价动能。

    影响分析

    • 采购成本：碳纤维成本推涨具有持续性——丙烯腈强势格局短期难破，下游复材、风电叶片、体育器材企业Q3采购成本预计上升3–8%。PTFE、陶瓷原料采购窗口相对友好。
    • 供应链：高端PI薄膜（电子级、柔性显示用）仍高度依赖进口（杜邦、宇部、钟渊、SK），供应集中度高，地缘或贸易扰动下断供风险大于价格风险；建议关键客户维持双源供应。

    行动建议

    • 建议锁价：碳纤维（尤其T300大丝束及T700）——头部企业已启动提价，且丙烯腈库存红利（部分企业仅够3–4个月）耗尽后或有第二轮上调，建议锁定Q3–Q4长单。
    • 建议观望：PTFE、特种陶瓷原料——供需双弱、价格底部盘整，无需提前备货，按需采购即可。
    • 建议关注：PEEK国产料价格下行通道中的替代验证机会；高端PI膜的国产化供应商（瑞华泰、国风新材等）导入测试。

  • 碳陶制动盘采购指南：中国供应商如何进入奔驰供应链

    在全球汽车制动系统向高性能、轻量化迈进的背景下，碳陶制动盘（Carbon Ceramic Brake Disc）凭借其卓越的热稳定性、耐磨性和制动一致性，已成为高端乘用车、赛车及部分轨道交通车辆的标配零部件。对于欧美汽车OEM和Tier1采购经理而言，了解中国碳陶制动盘供应商的能力边界、认证路径与品控体系，是实现供应链多元化的关键课题。

    一、碳陶制动盘 vs 铸铁刹车：核心差异与适用场景

    碳陶制动盘与铸铁刹车盘的本质区别在于基体材料：前者以碳纤维增强碳化硅复合材料（C/SiC）为核心，后者以灰铸铁为主。两者在关键性能指标上的差异直接决定了适用场景的分化。

    参数 碳陶制动盘（C/SiC） 铸铁刹车盘
    最高工作温度 1200°C（短时峰值） 约650°C
    重量（同级车型） 减轻约50%~60% 基准
    使用寿命 30万~50万公里 5万~8万公里
    摩擦系数稳定性 热衰减极低 高温下明显衰减
    单件成本 高（量产规模效应可降低） 低
    主要应用 高端轿车、赛车、轨道交通 经济型乘用车、商用车

    核心痛点：铸铁刹车盘在连续制动或高速制动场景下，温度超过临界点后摩擦系数急剧下降（称为”热衰减”），直接威胁制动安全。碳陶材料的热导率和比热容均优于铸铁，且氧化率极低，在1000°C以上仍能保持稳定的摩擦特性。对于装备高功率电机的电动汽车和高端性能车，这是选择碳陶方案的决定性因素。

    二、金博股份的碳陶制动盘：认证、参数与量产能力

    湖南金博碳素股份有限公司（简称”金博股份”，股票代码：688598.SH）总部位于湖南益阳，是国内碳/碳复合材料领域的龙头企业。公司早期以光伏、半导体用碳碳热场材料起家，2019年起战略布局碳陶制动盘业务，依托碳纤维预制体编织和化学气相浸渗（CVI）两大核心技术，迅速建立了完整的碳陶复合材料工艺体系。

    • 热膨胀系数：≤4.5×10⁻⁶ /K（室温~800°C）
    • 热导率：≥30 W/(m·K)
    • 最高工作温度：1200°C（惰性气氛），900°C（大气环境）
    • 摩擦系数：0.35~0.55（可调节配方）
    • 单盘重量：较同级铸铁盘减重约60%
    • 表面处理：抗氧化涂层（SiC外涂），满足500h盐雾测试

    认证进展

    金博股份于2023年正式进入梅赛德斯-奔驰乘用车制动盘供应商体系（SOP时间线按双方保密协议执行），这标志着中国碳陶制动盘供应商首次进入全球顶级OEM供应链。与国际竞争对手（如Brembo、Carbon Ceramics/Brembo旗下碳陶业务）相比，金博的成本结构优势约为20%~30%，在规模化量产后这一差距有望进一步扩大。

    公司同时通过了IATF 16949:2016汽车行业质量管理体系认证，碳陶制动盘产品已通过部分主机厂的内部DV（Design Verification）和PV（Process Validation）验证。

    量产能力

    三、海外采购碳陶制动盘的品质验证流程

    对于进口商和OEM采购团队而言，建立系统的来料验证体系是降低供应链风险的核心手段。以下为建议的验证流程框架：

    Step 1：文件审查（Document Review）

    • 核对材料成分表（C/SiC体积分数、碳纤维含量）
    • 验证热处理工艺记录（最高热处理温度、保温时间、冷却速率）
    • 确认表面涂层工艺规范及厚度参数
    • 审查尺寸公差图纸与CMM报告

    Step 2：理化性能测试（Physical Testing）

    • 密度与气孔率：阿基米德法测定，要求开孔率<3%
    • 三点弯曲强度：ISO 14704或GB/T 10700执行
    • 热膨胀系数：热机械分析仪（TMA）测定
    • 摩擦磨损试验：使用Link制动惯性试验台或SAE J2522标准进行衰退试验

    Step 3：台架验证（Bench Testing）

    • 制动盘总成惯性台架试验，模拟城市工况（NEDC/WLTC循环）
    • 高温制动衰退测试：连续10次100km/h→0制动，监测温度与摩擦系数曲线
    • 噪声、振动与声振粗糙度（NVH）测试

    Step 4：整车道路试验（On-Vehicle Testing）

    完成台架测试后，需在目标车型上进行实际道路验证，周期通常为6~12个月，依据主机厂规范执行。

    四、碳陶制动盘出口合规：认证文件与关税注意事项

  • Industrial Materials Procurement from China: A Step-by-Step Playbook for Overseas Buyers — RFQ, Sampling, QC, Incoterms and Customs

    Why This Guide Exists

    China is now the world’s largest producer of advanced engineering plastics, high-performance composites, specialty polymers and next-generation energy materials. For an overseas procurement team, the opportunity is real—but so are the pitfalls: vague specifications, inconsistent batches, hidden landed costs, and customs surprises. This playbook walks you through a repeatable, ten-step workflow for sourcing industrial and new materials from China, from the first RFQ to final customs clearance. It is written for buyers, not for supplier auditors: the focus is on product quality, transaction security, and total cost control.

    1. Start With a Precise Specification Sheet

    Before you contact a single factory, write down exactly what you need. A strong spec sheet removes ambiguity and lets suppliers quote like-for-like.

    • Base material & grade: e.g., PEEK (polyether ether ketone) 450G natural, or carbon-fiber prepreg T800 unidirectional.
    • Standards: ASTM, ISO, EN, or GB references that define the test methods you accept.
    • Key properties: tensile strength, HDT, melt flow, impurity limits, particle size, moisture content—whatever drives your application.
    • Form & packaging: pellets, sheet, roll, prepreg roll, or powder; bag/drum quantity; moisture-barrier requirements.
    • Certificates needed: COA (Certificate of Analysis), RoHS/REACH, FDA/ISO 10993 for medical, NADCAP for aerospace.

    2. Build a Focused RFQ

    Send the same spec sheet to 5–8 candidate suppliers. Keep the RFQ structured so answers are comparable:

    • Unit price and MOQ (minimum order quantity)
    • Lead time and production capacity
    • Available certificates and test reports
    • Sample policy (free or charged, who pays freight)
    • Incoterm and port of loading

    Tip: ask for a recent COA of a similar grade so you can judge real-world consistency before committing.

    3. Shortlist and Request Samples

    Rank replies by completeness and realism, then request physical samples. For sensitive materials, specify storage and transit conditions in the RFQ—PEEK and carbon-fiber prepreg are moisture-sensitive and prepreg must stay cold-chained.

    4. Validate Samples With Independent Testing

    Do not rely on the supplier’s in-house report alone. Engage a third-party lab (SGS, BV, TÜV, or a local accredited lab) to verify the critical properties on your spec sheet. Independent verification of the product is the single most effective quality-control step—and it is distinct from auditing the supplier’s internal systems.

    5. Compare Total Landed Cost, Not Unit Price

    The cheapest ex-works quote is rarely the cheapest delivery. Build a cost model:

    • Unit price + domestic freight to port
    • Packaging for long transit (desiccant, moisture barrier, shock protection)
    • International freight (sea vs air) and insurance
    • Import duties, VAT, and brokerage at your end
    • Tooling, certificates, and inspection fees

    6. Lock the Contract and Incoterms

    Choose an Incoterm that matches your risk appetite:

    • EXW: you control everything from the factory gate—maximum control, maximum effort.
    • FOB: supplier delivers to vessel; you book freight and insurance.
    • CIF: supplier covers freight and insurance to your port.
    • DDP: supplier handles everything to your door, duties included—convenient but less transparent on cost.

    Put specs, certificates, penalties for non-conformance, and dispute venue in writing.

    7. Protect Payment With Secure Terms

    Avoid paying 100% upfront. Common, safer structures:

    • 30% deposit + 70% against bill of lading (B/L) copy
    • Irrevocable letter of credit (L/C) for larger first orders
    • Escrow or platform-held payment released on inspection pass

    8. Monitor Production and Pre-Shipment Inspection

    For ongoing or high-value orders, request a production schedule and a pre-shipment inspection (PSI) by a third party. The PSI confirms quantity, packaging, labeling, and a visual/measured check against spec before the container seals.

    9. Plan Logistics and Protective Packaging

    Industrial materials often need special handling:

    • Moisture-sensitive polymers & prepreg: aluminum-foil barrier bags with desiccant; prepreg in reefer containers.
    • Composites & rolls: core protectors, edge cushions, upright racking.
    • Hazmat / batteries: UN packaging, MSDS, and DG declarations.

    10. Clear Customs and Stay Compliant

    Get the HS code right and prepare documents early: commercial invoice, packing list, bill of lading, certificate of origin, COA, and MSDS where applicable. Confirm REACH/RoHS or regional substance rules for your market. Misclassified HS codes are the most common cause of clearance delays and penalties.

    Material-Specific Handling Notes

    • PEEK (aerospace, medical, semiconductor): verify melt flow and purity; medical grades need ISO 10993 / USP Class VI; semiconductor grades need low ionic contamination. Keep dry.
    • Carbon-fiber prepreg (T800 etc.): cold chain (≈ -18 °C), track out-life, protect from porosity; autoclave vs out-of-autoclave process matters.
    • Carbon-fiber fabric: watch drape and sizing; marine/wet-layup grades differ from aerospace.
    • Perovskite PV modules: confirm stability protocols and encapsulation; emerging tech—validate the exact cell architecture.
    • Solid-state battery electrolytes: confirm moisture/temperature specs and handling certifications.

    Pre-Shipment Checklist

    • Spec sheet signed off and attached to PO
    • Independent sample test passed
    • Certificates (COA, RoHS/REACH, applicable) received
    • Incoterm, price, and payment terms confirmed in contract
    • Packaging and transit conditions verified
    • PSI passed; documents template ready for customs

    Bottom Line

    Sourcing industrial materials from China rewards discipline, not luck. A precise spec, comparable RFQs, independent sample testing, secure payment terms, and correct customs paperwork turn a risky purchase into a predictable supply line. Use this playbook as your standard operating procedure for every new-material purchase.

  • 从中国采购工业材料实战手册：海外采购商 RFQ、样品验证、质检、贸易术语与清关全流程指南

    为什么需要这份手册

    中国已是全球最大的高性能工程塑料、先进复合材料、特种聚合物及下一代能源材料生产国。对海外采购团队而言，机会真实存在——但陷阱同样不少：规格含糊、批次不稳、到岸成本被隐藏、清关意外频发。本手册提供一套可复用的十步工作流，带您从首份询价（RFQ）一路走到最终清关，系统梳理从中国采购工业与新材料的方法。本文写给采购方，而非供应商审计方：重点放在产品质量、交易安全与总成本管控上。

    1. 先做精确的规格书

    在联系任何工厂之前，先把需求写清楚。一份严谨的规格书能消除歧义，让供应商”同口径”报价。

    • 基材与牌号：例如 PEEK（聚醚醚酮）450G 本色，或 T800 单向碳纤维预浸料。
    • 执行标准：标注您接受的 ASTM、ISO、EN 或 GB 测试方法标准。
    • 关键性能：拉伸强度、热变形温度、熔融指数、杂质上限、粒径、含水率——以您的应用为准。
    • 形态与包装：颗粒、板材、卷材、预浸料卷或粉末；每袋/每桶数量；防潮要求。
    • 所需证书：COA（分析证书）、RoHS/REACH、医疗级需 FDA/ISO 10993、航空级需 NADCAP。

    2. 制作结构化 RFQ

    把同一份规格书发给 5–8 家候选供应商，保持结构一致以便比价：

    • 单价与最小起订量（MOQ）
    • 交期与产能
    • 可提供的证书与检测报告
    • 样品政策（免费或收费，运费由谁承担）
    • 贸易术语与装运港

    建议：索取相近牌号近期的 COA，在下单前据此判断实际一致性。

    3. 筛选并索取样品

    按回复的完整度与合理性排序，再索取实物样品。对敏感材料，在 RFQ 中注明储运条件——PEEK 与碳纤维预浸料怕潮，预浸料必须冷链运输。

    4. 用第三方检测验证样品

    不要只信供应商的厂内报告。委托第三方实验室（SGS、BV、TÜV 或本地认可实验室）按您的规格书核验关键性能。对产品做独立验证，是性价比最高的一道质控关卡，也不同于对供应商内部体系的审核。

    5. 比较到岸总成本，而非单价

    工厂交货（EXW）最低的报价，往往不是到货最便宜的。建立成本模型：

    • 单价 + 至港口的国内运费
    • 长途运输包装（干燥剂、防潮层、防震）
    • 国际运费（海运 vs 空运）与保险
    • 目的国进口关税、增值税与报关费
    • 模具、证书与检测费用

    6. 锁定合同与贸易术语

    选择与风险偏好匹配的 Incoterm：

    • EXW：从工厂门口起一切由您掌控——控制最高，事务最多。
    • FOB：供应商货交承运人；您订舱与投保。
    • CIF：供应商承担至目的港的运费与保险。
    • DDP：供应商包办到门并含关税——省心，但成本透明度低。

    把规格、证书、不符罚则、争议管辖地都写进合同。

    7. 用安全付款条件护住资金

    避免 100% 预付。更稳妥的常见结构：

    • 30% 定金 + 70% 见提单（B/L）副本付款
    • 大额首单采用不可撤销信用证（L/C）
    • 托管或平台代付，验货合格后释放

    8. 生产跟进与发货前检验

    对持续或高价值订单，索取生产排期并安排第三方发货前检验（PSI）。PSI 在集装箱封箱前确认数量、包装、标签，并按规格做目视/实测核对。

    9. 规划物流与防护包装

    工业材料常需特殊处理：

    • 怕潮聚合物与预浸料：铝箔防潮袋加干燥剂；预浸料用冷藏箱。
    • 复合材料与卷材：纸管保护、边角缓冲、直立货架。
    • 危险品/电池：UN 包装、MSDS 与危险品申报。

    10. 清关与合规

    准确归类 HS 编码并提早备单：商业发票、装箱单、提单、原产地证、COA，以及适用的 MSDS。确认目的市场的 REACH/RoHS 或区域物质法规。HS 归类错误是清关延误与罚款最常见的原因。

    分材料储运要点

    • PEEK（航空、医疗、半导体）：核验熔融指数与纯度；医疗级需 ISO 10993 / USP Class VI；半导体级需低离子污染；保持干燥。
    • 碳纤维预浸料（T800 等）：冷链（约 -18 °C）、追踪适用期（out-life）、防孔隙；热压罐与免热压罐工艺有差别。
    • 碳纤维织物：关注悬垂性与上浆剂；海洋/湿法铺层牌号不同于航空级。
    • 钙钛矿光伏组件：确认稳定性方案与封装；属新兴技术——核验具体电池结构。
    • 固态电池电解质：确认温湿度规格与操作证书。

    发货前清单

    • 规格书已签批并附于采购单
    • 第三方样品检测已通过
    • 证书（COA、RoHS/REACH 及适用项）已收到
    • 贸易术语、价格、付款条件已在合同中确认
    • 包装与储运条件已核实
    • PSI 通过；清关单据模板已就绪

    核心结论

    从中国采购工业材料，靠的是纪律而非运气。精确的规格、可比的 RFQ、独立的样品检测、安全的付款条件，加上正确的清关文件，能把一次高风险采购变成一条可预测的供应线。把本手册作为每次新材料采购的标准作业流程。
