  • 2026-05-06 Advanced Materials Price Trend Daily

    Price Overview

    Material Current Price Range WoW Trend
    PTFE Dispersion Resin 50,000-58,000 CNY/ton Flat → Stable
    PEEK Pure Resin (Imported) 350-980 CNY/kg +2%~3% ↑ Slight Increase
    Carbon Fiber (T300 Grade) 120,000-145,000 CNY/ton +5%~8% ↑↑ Significant Rise
    PI Film (Domestic) 475-600 CNY/kg Flat → Stable
    Specialty Ceramic Raw Materials (Al2O3 75%) 2,000-2,400 CNY/ton Flat → Stable

    Key Changes

    • Carbon Fiber: +5%~8% — The most significant move this week. Jilin Chemical Fiber raised all grades by 5,000 CNY/ton in early April, followed by an additional 10,000 CNY/ton hike on wet-process 3K carbon fiber. PAN precursor surged past 37,000 CNY/ton, up 41% WoW. Drivers: ① Sharp rise in acrylonitrile feedstock costs; ② Middle East tensions pushing energy prices higher; ③ Explosive demand growth from low-altitude economy, UAVs, and wind energy; ④ Sustained supply shortage for T800+ high-end grades.
    • PEEK Pure Resin: +2%~3% — Imported Victrex 450G quotes edging higher; high-end medical/semiconductor grades tightening. DIC raised epoxy resin and curing agent prices effective April 15 (up to 280 JPY/kg), signaling cost pressure across specialty resins.
    • PTFE Dispersion Resin: Flat — Fuxin Hengtong quoted at 54,000 CNY/ton, unchanged. Hexafluoropropylene at 36,400 CNY/ton with stable supply. Juhua’s 44,000-ton TFE capacity expansion underway, potentially easing mid-term supply.
    • PI Film: Flat — Domestic PI film around 475 CNY/kg; DuPont high-end grades at 2,000 CNY/kg. Electronics-grade PI film demand driven by flexible circuits and OLED, but accelerating domestic substitution caps upward price movement.
    • Specialty Ceramic Raw Materials: Flat to Firm — Bauxite (Al2O3 75%) at 2,400 CNY/ton. Guocai Materials explicitly monitoring zirconia powder market changes and preparing to adjust pricing strategies — a price hike is anticipated.

    Impact Analysis

    Procurement Cost Impact

    • Carbon fiber price hikes most severely impact wind blade, aerospace, and low-altitude economy procurement, adding 5,000-10,000 CNY/ton in cost
    • Modest PEEK increases have limited impact on semiconductor/medical high-end parts, but import-dependent buyers should monitor FX risk
    • PTFE and PI film stability means sealing and flexible circuit sectors see manageable short-term costs

    Supply Chain Impact

    • Carbon fiber supply chain tightening intensifies — domestic leaders (Jilin Chemical Fiber, Hengshen, Guangwei) have all issued price increase notices; Japan’s Toray raising prices in parallel, signaling global supply contraction
    • Middle East geopolitical risks continue driving crude oil and acrylonitrile prices higher, sustaining carbon fiber cost support in the near term
    • Zirconia powder price hike expectations rising — downstream dental and specialty ceramics firms should lock in prices early

    Actionable Recommendations

    • Lock Prices Now: Carbon fiber (especially T700/T800 high-end grades) and zirconia powder — price increase cycle underway; delayed procurement carries significant cost risk
    • Strategic Restocking: Imported PEEK pure resin — moderate increases but tightening supply; semiconductor/medical buyers should secure H2 volumes during Q2
    • Monitor Only: PTFE dispersion resin and PI film — stable supply-demand fundamentals, no major volatility risk in the near term; maintain normal procurement cadence
    • Key Watch: Acrylonitrile price trajectory and Middle East situation evolution — these are the core variables determining carbon fiber’s next price direction

    影响分析

    对采购成本的影响

    • 碳纤维涨价对风电叶片、航空航天及低空经济领域采购成本冲击最大，单吨成本增加5,000-10,000元
    • PEEK小幅上涨对半导体/医疗行业高端零件成本影响有限，但进口依赖型采购需关注汇率波动
    • PTFE与PI薄膜价格稳定，相关密封件和柔性电路领域短期成本可控

    对供应链的影响

    • 碳纤维供应链紧张加剧，国内龙头（吉林化纤、恒神股份、光威复材）均已发布调价函，国际巨头日本东丽同步涨价，全球供给收缩
    • 中东地缘政治风险持续推高原油及丙烯腈价格，碳纤维成本支撑短期难以缓解
    • 氧化锆粉体提价预期升温，下游齿科和特种陶瓷企业需提前锁定价格

    行动建议

    • 建议锁定价格：碳纤维（特别是T700/T800高端品种）和氧化锆粉体 — 当前涨价通道已开启，延迟采购成本风险大
    • 建议择机补库：PEEK进口纯树脂 — 涨幅温和但供应偏紧，半导体/医疗客户宜在Q2提前锁定H2用量
    • 建议观望：PTFE分散树脂和PI薄膜 — 供需格局稳定，短期无大幅波动风险，可按常规节奏采购
    • 重点关注：丙烯腈价格走势和中东局势演变，这是碳纤维后续价格方向的核心变量

  • Comprehensive Review of Aluminum Nitride (AlN) Ceramic Substrates for High-Power Electronics

    Product Review: Aluminum Nitride (AlN) Ceramic Substrates for High-Power Electronics

    Aluminum Nitride (AlN) ceramic substrates have emerged as the go-to thermal management solution for high-power electronic devices in recent years, outperforming traditional alumina (Al₂O₃) and aluminum nitride composites in both thermal conductivity and electrical insulation. This review evaluates the mainstream industrial-grade AlN substrates from LiiFooRoom, focusing on specification compliance, application adaptability, and selection best practices.

    Specifications & Parameters

    LiiFooRoom’s industrial-grade AlN substrates comply with IPC-4101D standards, with core parameters as follows:

    • Thermal conductivity: 175–200 W/m·K (tested per ASTM E1461 laser flash method, 30% higher than alumina substrates)
    • Volume resistivity: >1×10¹⁴ Ω·cm (at 25°C, 50% RH), meeting Class I insulation requirements for high-voltage applications
    • Dielectric constant: 8.8 ± 0.2 (1 MHz, 25°C), with dielectric loss tangent < 0.001
    • Coefficient of thermal expansion (CTE): 4.5 ± 0.1 ppm/°C (20–300°C), perfectly matching silicon (4.1 ppm/°C) and SiC (4.0 ppm/°C) chips to avoid thermal stress cracking
    • Available thicknesses: 0.25mm, 0.38mm, 0.5mm, 1.0mm (tolerance ±0.02mm)
    • Maximum panel size: 150mm × 150mm, with surface roughness Ra < 0.08μm for direct copper bonding (DCB) compatibility
    • Operating temperature range: -55°C to 850°C, with no phase change or performance degradation

    Application Scenarios

    Based on third-party testing and customer feedback, LiiFooRoom’s AlN substrates are widely adopted in the following high-value industrial scenarios:

    • New energy vehicle (NEV) power modules: Used as the baseplate for IGBT and SiC MOSFET modules, with 30% lower junction temperature than alumina substrates under 200A continuous current load, extending module lifespan by 40%.
    • 5G base station RF devices: Serves as the heat dissipation carrier for GaN power amplifiers, supporting 100W+ continuous RF output power with stable dielectric performance to avoid signal distortion.
    • High-power LED packaging: Applied in 100W+ industrial street lights and automotive headlights, reducing LED chip junction temperature by 15°C to improve luminous efficiency by 12%.
    • Aerospace electronics: Used in satellite power supplies and avionics systems, with stable performance under extreme temperature cycling (-55°C to 125°C) and low outgassing rate meeting NASA low-outgassing standards.

    Selection Guide

    To maximize performance and cost efficiency, follow these selection principles when procuring AlN substrates:

    • Thickness selection: For power density > 150W/cm² (e.g., SiC power modules), choose 0.25mm ultra-thin substrates to minimize thermal resistance; for conventional power devices (<100W/cm²), 0.5mm or 1.0mm substrates offer better mechanical strength.
    • Surface treatment: Select gold-plated (Au) or silver-plated (Ag) surfaces for soldering processes, and polished bare surfaces for direct copper bonding (DCB) or active metal brazing (AMB) processes.
    • Size customization: For small signal devices, 50mm×50mm standard panels are cost-effective; for large power modules, custom 150mm×150mm panels reduce splicing costs and thermal interface resistance.
    • Parameter verification: Require suppliers to provide third-party test reports for thermal conductivity and CTE, and avoid products with “typical value” labels without batch test data.

    Overall, LiiFooRoom’s AlN ceramic substrates deliver reliable performance in high-power electronic scenarios, with stable parameter consistency and competitive pricing for industrial batch procurement. They are recommended for enterprises upgrading from alumina substrates to high-performance thermal management solutions.
