  • 2026-07-19 Price Trend Daily Report

    1. Price Overview

    Material Current Price Range WoW Trend
    PTFE Resin 30k–52k CNY/ton -4% Down
    PEEK Resin Domestic 370k–400k CNY/ton; Import 900k–1.5M CNY/ton +1% Stable (structural upside)
    Carbon Fiber T300 grade 78k–95k CNY/ton; T700 grade 118k CNY/ton +1.5% Up
    PI Film Electronic grade ≥1M CNY/ton +2% Up
    Specialty Ceramic Raw Materials Zirconia 89k CNY/ton; Nano alumina 150k CNY/ton 0% Stable

    2. Key Movements

    • PTFE Resin: -4%. Major quotes in East China and Shandong fell to 34k–50k CNY/ton; Luxi Chemical quoted 34k CNY/ton on Jul 17, down 1k from the prior day. Drivers: (1) anhydrous HF eased from its early-year peak (above 16k CNY/ton, ~+40% YTD) back to ~15k CNY/ton, weakening cost support; (2) new capacity keeps supply ample; (3) downstream buys only to need, thin trading — supply surplus persists.
    • Carbon Fiber: +1.5%. Toray raised TORAYCA series by 10%–20% from Jan 2026; Jilin Chemical followed (12K and 3K up 5k and 10k CNY/ton respectively), T300 12K around 95k CNY/ton. Prices are recovering from the post-overcapacity bottom as demand from wind power, hydrogen storage cylinders, robotics and auto light-weighting rebounds.
    • PI Film: +2%. Electronic grade (biaxially oriented) trades above 1M CNY/ton, heavily import-dependent and concentrated among DuPont, Ube, Kaneka, SK Kolon. EV, 5G and flexible electronics drive strong demand, creating a structural shortage.

    3. Impact Analysis

    • Procurement cost: Rising carbon fiber and PI film directly lift costs of advanced composites and electronic substrates; monthly gains already squeeze margins. Falling PTFE frees some cost room, but watch quality of low-end grades.
    • Supply chain: Carbon fiber and PI film rely heavily on imports; Toray and peers hold pricing power, so geopolitics/trade policy can trigger supply risk — build a multi-supplier base and strategic stock. PEEK localization is accelerating (domestic share ~60% by 2026), improving local supply security.

    4. Action Recommendations

    • Lock prices: Carbon fiber, PI film — clear upward trend and concentrated supply; sign mid/long-term contracts or lock in batches to avoid further hikes.
    • Wait and see: PTFE resin — still in a downtrend, delay bulk orders and restock as needed; PEEK resin and ceramic raw materials are stable, maintain a normal procurement rhythm.

  • 2026-07-19 价格趋势日报

    一、价格概览表

    材料 当前价格区间 周环比 趋势
    PTFE树脂 3.0–5.2万元/吨 -4% 下跌
    PEEK树脂 国产37–40万元/吨;进口90–150万元/吨 +1% 稳定(结构性上行)
    碳纤维 T300级7.8–9.5万元/吨;T700级11.8万元/吨 +1.5% 上涨
    PI薄膜 电子级≥100万元/吨 +2% 上涨
    特种陶瓷原料 氧化锆8.9万元/吨;纳米氧化铝15万元/吨 0% 稳定

    二、重点变动

    • PTFE树脂:-4%。华东、山东主流报价回落至3.4–5.0万元/吨,鲁西化工7月17日报价3.4万元/吨、较前日下调1000元。主因:(1)无水氢氟酸从年初高位(一度16000+元/吨,年内涨幅近40%)回落至1.5万元/吨附近,成本支撑减弱;(2)新增产能持续释放,市场供应宽松;(3)下游按需采购、成交清淡,供强需弱格局未改。
    • 碳纤维:+1.5%。日本东丽自2026年1月起上调TORAYCA系列10%–20%,吉林化纤同步跟涨(12K、3K分别上调0.5万、1万元/吨),T300 12K报盘约9.5万元/吨。当前价格处于产能出清后的修复通道,风电、氢能储氢瓶、机器人及汽车轻量化需求回暖,价量齐升。
    • PI薄膜:+2%。电子级(双轴向拉伸)市场价格100万元/吨以上,严重依赖进口、供给高度集中(杜邦、宇部、钟渊、SK Kolon),新能源车、5G、柔性电子带动需求快速增长,呈现结构性短缺。

    三、影响分析

    • 采购成本:碳纤维与PI薄膜持续上行将直接抬升高端复材与电子基材采购成本,单月累计涨幅已对毛利形成挤压;PTFE下行则释放部分成本空间,但需警惕低端料品质波动。
    • 供应链:碳纤维、PI薄膜对外依存度高,东丽等海外巨头掌握定价权,地缘与贸易政策变动易引发断供风险,建议建立多元供应商与战略库存。PEEK国产替代加速(2026年国产份额预计升至60%),本土供给安全性改善。

    四、行动建议

    • 建议锁定价格:碳纤维、PI薄膜——上行趋势明确、供给集中,宜签订中长期协议或分批锁价,规避后续提价。
    • 建议观望:PTFE树脂——仍在下行通道,可延后大单采购、按需补货;PEEK树脂与特种陶瓷原料价格平稳,维持常规采购节奏即可。

  • Toray Carbon Fiber Prepreg T800 FAQ: Cure, Storage, and Handling Questions for Composite Engineers (2026)

    What is Toray Carbon Fiber Prepreg T800?

    Toray Carbon Fiber Prepreg T800 is an aerospace-grade composite in which Torayca T800 intermediate-modulus carbon fibers are pre-impregnated with a controlled amount of epoxy resin on a backing film. Prepreg means fiber and matrix are combined at the supplier under tight control, so the laminator receives a ready-to-lay-up sheet with consistent resin content. The T800 fiber provides about 5.5 GPa tensile strength with an intermediate modulus near 294 GPa, making it a main choice for primary aircraft structures where strength-to-weight and damage tolerance are critical.

    Which resin systems are available for T800 prepreg?

    Toray offers T800 prepreg with several epoxy systems for different processes. Common options include 250 F (121 C) curing toughened epoxies for general airframe use and higher-temperature 350 F (177 C) systems for engine-adjacent or demanding structural zones. The resin choice sets the cure cycle, service temperature, toughness, and out-of-autoclave capability. Buyers should match the resin system to the part design allowables and the qualified process on file.

    What are the key mechanical properties?

    With T800 fibers, typical unidirectional laminate properties reach tensile strengths above 2,500 MPa and compressive strengths near 1,500 MPa in the fiber direction, plus good interlaminar fracture toughness from the toughened epoxy. The intermediate modulus gives better stiffness than T300-class fibers without the cost and brittleness of high-modulus grades, which explains why T800 dominates modern fuselage and wing skins.

    How should T800 prepreg be stored and what is its shelf life?

    Prepreg is temperature-sensitive and must stay frozen, typically at -18 C (0 F) or below, in sealed moisture-barrier packaging. Under proper frozen storage, out-life can reach 6 to 12 months depending on the resin system. After removal from the freezer, a controlled thaw inside the sealed bag prevents condensation, after which a limited room-temperature out-life of often 7 to 30 days applies before the resin advances too far to process.

    What are tack and drape, and why do they matter?

    Tack is the surface stickiness that lets plies adhere during hand or automated lay-up. Drape is how well the prepreg conforms to complex contours. T800 prepreg is formulated with enough tack and drape to handle double-curvature tooling while staying controllable. Too much tack causes bridging on steep radii, while too little leads to ply lift-off. The specified tack window is part of the material process specification.

    What cure cycle is typical?

    A standard autoclave cure ramps to the gel temperature, holds under vacuum to remove volatiles, then applies full consolidation pressure of often 3 to 7 bar and dwells at the resin cure temperature, commonly 177 C for 2 to 3 hours, followed by a controlled cooldown. Out-of-autoclave variants use vacuum-bag-only processing with engineered bleeder and breather layers but need careful compaction to avoid porosity.

    Autoclave or out-of-autoclave?

    Autoclaves remain the default for the most demanding primary structures because external pressure drives out voids and ensures low porosity. OOA prepreg reduces capital and energy cost and suits larger tools that will not fit an autoclave, but it demands stricter process control and tends to show slightly higher void content if not optimized.

    Is T800 prepreg qualified to aerospace standards?

    Yes. Toray T800-based systems are qualified under major airframe specifications and backed by full material qualification data, including aged properties and allowable databases. Procurement should require the certificate of analysis, lot traceability, and the qualified resin and fiber combination documented in the relevant process specification.

    Any tips for cutting and kitting?

    Use sharp, dedicated prepreg scissors or a chilled knife, and plan plies to limit waste. Automated ply cutters with vision systems improve accuracy for production. Keep kitting at controlled temperature and return unused material to frozen storage promptly to preserve out-life.

    How does cost compare with other grades?

    T800 prepreg costs more than standard-modulus T300-class material but less than high-modulus or ultra-high-toughness aerospace systems. Savings come from thinner, lighter structures and fewer plies for the same strength, which often offsets the higher per-kilo price over a program life.
