    2026-07-11 Price Trend Daily Report

    Price Overview

    Material Current Price Range WoW Change Trend
    PTFE Resin RMB 30k–52k/t -3% to -5% Declining
    PEEK Resin RMB 300k–400k/t (domestic); RMB 800k+/t (import) +1% to +3% Slight Up
    Carbon Fiber RMB 100k–150k/t +1% to +2% Rising
    PI Film RMB 600k–3.0M/t (electronic grade ≥RMB 1.0M/t) +1% to +2% Firm / Up
    Specialty Ceramic Raw Materials (Zirconium Oxychloride) RMB 18.8k/t; high-purity zirconia USD 50–65.7/kg +5% to +6% Sharply Up

    Key Movements

    • PTFE Resin: -3% to -5%. Weak demand and ample supply; Luxi Chemical cut quotes from RMB 35k to RMB 34k/t, and the PTFE spread is near historic lows. High fluorite/HF costs provide a floor, but soft demand caps upside.
    • Specialty Ceramic Raw Materials (Zirconium Oxychloride): +5% to +6%. Tosoh halted supply to domestic dental, electronic-ceramic and optical-communication customers, widening the high-end zirconia gap. Solid-state batteries, MLCC, photovoltaics and nuclear power jointly boost zirconium demand.
    • PEEK Resin: +1% to +3%. Demand surge from humanoid robots, the low-altitude economy and semiconductor equipment, with accelerating domestic substitution, keeps prices firm at a high level.
    • Carbon Fiber: +1% to +2%. Toray raised prices 10%–20% and Jilin Chemical lifted its 12K/3K by RMB 5k/10k per ton at the start of the year; elevated energy and logistics costs sustain the strength.

    Impact Analysis

    • On procurement cost: The PTFE softness benefits downstream sealing and cable makers on cost. However, carbon fiber, zirconium-based ceramics and PI film are in up or tight channels, pressuring budgets for aerospace, new-energy and electronic-packaging players, who should lock prices early.
    • On supply chain: Enterprises with high overseas dependence on zirconium feedstock face supply-interruption risk; domestic oxychloride substitution is accelerating but near-term supply remains tight. Combined with overseas carbon-fiber hikes and logistics costs, lead times for import-dependent segments are lengthening.

    Action Recommendations

    • Lock prices now: Carbon fiber, high-purity zirconia / zirconium oxychloride, and electronic-grade PI film — the up and shortage trends are clear; sign mid-to-long-term lock-in agreements or build safety stock.
    • Wait and watch: PTFE resin — ample supply and weak demand leave room for further downside; maintain just-in-time purchasing.
    • PEEK resin: Build positions in batches for rigid demand, and watch for pullbacks as new domestic capacity comes online.

    特种陶瓷原料（氧氯化锆） 1.88万元/吨；高纯氧化锆50–65.7美元/kg +5%~+6% 明显上涨

    重点变动

    • PTFE树脂：-3%~-5%。需求疲软、供应宽松，鲁西化工报价由3.5万降至3.4万元/吨，行业价差逼近历史底部；成本端萤石/氢氟酸高位，但需求不足压制价格。
    • 特种陶瓷原料（氧氯化锆）：+5%~+6%。东曹暂停对国内齿科、电子陶瓷、光通信企业供货，高端氧化锆供需缺口扩大；固态电池、MLCC、光伏、核电多领域共振推升锆需求。
    • PEEK树脂：+1%~+3%。人形机器人、低空经济、半导体设备需求爆发，国产替代加速，价格高位企稳上行。
    • 碳纤维：+1%~+2%。年初东丽提价10%–20%、吉林化纤12K/3K分别上调0.5万/1万元每吨，能源与物流成本高位，价格维持强势。

    影响分析

    • 对采购成本的影响：PTFE走弱利好下游密封、线缆企业降本；但碳纤维、特种陶瓷（锆）及PI薄膜处于上行或紧缺通道，航空航天、新能源、电子封装企业采购成本承压，需提前锁价。
    • 对供应链的影响：锆系原料对外依赖度高的企业面临断供风险，国产氧氯化锆替代加速但短期供给仍紧；碳纤维海外提价叠加物流成本，进口依赖环节交期拉长。

    行动建议

    • 建议锁价：碳纤维、高纯氧化锆/氧氯化锆、电子级PI薄膜——上行与紧缺趋势明确，宜签订中长期锁价协议或建立安全库存。
    • 建议观望：PTFE树脂——供应宽松、需求偏弱，价格仍有下探空间，维持按需采购即可。
    • PEEK树脂：刚需可分批建仓，关注国产新产能释放带来的回落机会。

  • Alumina Ceramic Industrial Procurement Guide: Key Points for Sourcing High-Temperature Wear-Resistant Materials from China (2026)

    Why Choose Alumina Ceramics?

    Alumina (Al₂O₃) is the most widely used advanced ceramic material in industrial applications today. With excellent high-temperature resistance (up to 1600°C), outstanding wear resistance, good electrical insulation, and chemical stability, it serves as a core material in mining machinery, electronic components, and refractory components. Compared to zirconia and silicon carbide, alumina offers a superior cost-performance balance, making it especially suitable for large-volume industrial procurement.

    Core Technical Parameters

    • Al₂O₃ Content: Common grades include 75%, 90%, 95%, and 99% purity. Higher purity means better thermal resistance and insulation, but higher cost.
    • Density: Theoretical density 3.98 g/cm³; industrial products typically ≥3.6–3.9 g/cm³. Higher density indicates denser grain structure.
    • Rockwell Hardness: HRA 80–92; 95% Al₂O₃ typically HRA≥85.

  • 氧化铝陶瓷工业采购指南：耐高温耐磨材料从中国采购的核心要点（2026版）

    为什么选择氧化铝陶瓷？

    氧化铝（Al₂O₃）是目前工业应用最广泛的先进陶瓷材料。其优异的耐高温性（最高使用温度达1600°C）、卓越的耐磨性、良好的电绝缘性和化学稳定性，使其成为矿山机械、电子元件、耐火构件等领域的核心材料。相比氧化锆和碳化硅，氧化铝在成本与性能的平衡上具有显著优势，尤其适合大批量工业采购。

    氧化铝陶瓷的核心性能参数

    • 氧化铝含量（Al₂O₃ Content）：常见牌号包括75%（75% Al₂O₃）、90%（90% Al₂O₃）、95%（95% Al₂O₃）和99%（99% Al₂O₃）。纯度越高，耐温性能和电绝缘性越强，但成本也相应提高。
    • 密度（Density）：理论密度3.98 g/cm³；工业级产品通常≥3.6–3.9 g/cm³，密度越高晶粒越致密。
    • 洛氏硬度（Hardness）：HRA 80–92，95% Al₂O₃通常HRA≥85。
    • 抗弯强度（Flexural Strength）：300–400 MPa（95% Al₂O₃），99% Al₂O₃可达500 MPa。
    • 耐压强度（Compressive Strength）：2500–3000 MPa。
    • 热膨胀系数（Coefficient of Thermal Expansion）：7.2–8.0 × 10⁻⁶ /°C（25–1000°C）。
    • 热导率（Thermal Conductivity）：20–30 W/(m·K)。
    • 电阻率（Volume Resistivity）：10¹⁴–10¹⁵ Ω·cm（95–99% Al₂O₃）。

    常见规格与采购形态

    按形态分类

    国内厂家已具备从原料加工到精密加工的全链条能力，95% Al₂O₃陶瓷件价格通常比欧美日供应商低40–60%，是中国采购的核心价值所在。

    采购流程与质量控制要点

    标准采购流程

    1. 需求确认：明确氧化铝含量、尺寸公差、表面处理要求。
    2. 样品确认（Sample Approval）：大货前务必索取2–5件样品测试性能参数。
    3. 小批量试单：首次采购建议100–500件，验证供应商交期和质量稳定性。
    4. 批量订单：确认样品合格后，签订正式合同，明确技术规范和验收标准。
    5. 出货检验（Outgoing Inspection）：要求供应商提供出厂检测报告（材质单/Certificate of Conformance）。

    质量控制必须项

    • 来料检测：X射线荧光光谱（XRF）验证Al₂O₃含量；阿基米德法测密度。
    • 尺寸检验：关键尺寸全检或AQL 1.0抽样。
    • 外观检验：无裂纹、无崩边、无明显色差，表面缺陷按双方确认标准执行。

    • 最小起订量（MOQ）：常规产品MOQ 50–200件，定制件可能要求500件以上。

    物流与付款建议

    • 运输方式：样品和小批量走DHL/FedEx空运（3–7天），批量订单走海运拼箱（25–35天）。
    • 包装要求：陶瓷件必须使用泡沫垫+纸箱+托盘包装，要求供应商加”易碎品”标识。
    • 付款方式：新客户建议30%预付+70%提单副本支付；有合作历史后可谈T/T 45–60天或L/C。
    • 关税注意：氧化铝陶瓷通常归入HS Code 6903，欧美进口关税5–6.5%，请提前确认。

    总结：氧化铝陶瓷中国采购核心清单

    • ✅ 先确认Al₂O₃含量需求（75%/90%/95%/99%）
    • ✅ 要求样品测试密度、硬度、尺寸公差
    • ✅ 小批量试单验证质量稳定性后再下大单
    • ✅ 选择有ISO认证和出口经验的供应商
