  • 2026-04-23 Price Trend Daily Report

    Price Overview

    Material Current Price Range WoW Trend
    PTFE Suspension Resin (Medium Grain) 47,000-54,000 CNY/ton Flat → Stable
    PEEK Resin (Industrial Grade) 300,000-500,000 CNY/ton -3%~0% ↓ Slight Decline
    PEEK Resin (Medical Grade) 800,000-1,000,000 CNY/ton Flat → Stable
    Carbon Fiber (T300/T700 General Grade) 84-90 CNY/kg +3.1% ↑ Bottom Rebound
    Carbon Fiber Precursor 37,000 CNY/ton +41% ↑↑ Sharp Surge
    PI Film (Electronic Grade) 180-500 CNY/m² Flat → Stable
    Alumina (Futures) 2,601-2,675 CNY/ton -2.6% ↓ Slight Pullback
    Zirconia Powder (Industrial Grade) 28-30 CNY/kg Flat → Stable

    Key Changes

    • Carbon Fiber Precursor: +41% — On April 9, precursor prices surged 41% in a single day, breaking through 37,000 CNY/ton. Hengshen Co. led the price increase at 5,000-10,000 CNY/ton, followed by Jilin-series, Shanghai-series, and Toray. This rally is driven by rising acrylonitrile costs and a fundamental supply-demand reversal. Q1 2026 average carbon fiber price rose 3.07% YoY, ending a three-year downtrend.
    • PTFE Suspension Medium Grain: Flat — Oilchem reported 47,000-54,000 CNY/ton on April 17. Luxi Chemical recently cut 1,000 CNY/ton to 34,000 CNY/ton, but the overall market remains stable with no major supply disruptions.
    • PEEK Industrial Grade: Slight Decline — Domestic PEEK prices have fallen from a peak of 800,000-1,200,000 CNY/ton to 300,000-500,000 CNY/ton. Localization rate increased from 18% (2020) to 42%, with a 2026 policy target of 60%. Accelerating substitution continues to push industrial-grade prices down, while medical-grade remains firm at 800,000-1,000,000 CNY/ton.
    • Alumina Futures: -2.6% — AO2605 closed at 2,673 CNY/ton with a weekly drop of 2.6%. Capacity release and loose inventory are the main drivers, with cautious market sentiment prevailing.

    Impact Analysis

    Procurement Cost Impact

    • Carbon fiber precursor surge will transmit to finished products, raising cost pressure for wind turbine blades and hydrogen storage tanks. T800+ high-end grades remain in tight supply with greater price elasticity.
    • PEEK domestic substitution dividend continues; industrial-grade procurement costs expected to decline further, benefiting semiconductor and automotive component manufacturers.
    • Weakening alumina reduces cost support for specialty ceramic raw materials, but powder processing has lagged price transmission — limited short-term impact.

    Supply Chain Impact

    • Carbon fiber price hikes may trigger advance order locking by downstream customers. Short-term demand pulse combined with insufficient supply elasticity could push Q2 price center further upward.
    • PI film electronic-grade demand remains stable (FPC, battery separators). Domestic Kapton alternatives are scaling up, reducing import dependency.

    Actionable Recommendations

    Lock-in Prices

    • Carbon Fiber: Precursor surge is a clear signal; finished product price increases are highly likely. Recommend securing Q2 T700-and-below general-grade order volumes in advance.
    • PTFE Suspension Medium Grain: Currently stable, but fluorine chemical supply chain faces environmental production curbs. H2 supply contraction risk warrants moderate inventory building.

    Wait and Watch

    • PEEK Industrial Grade: Domestic substitution accelerating; further price decline expected. Avoid large-volume lock-in; adopt small-batch, high-frequency procurement strategy.
    • Alumina: Futures continuing to weaken; supply-loose pattern unchanged. Wait for lower price levels before large-order procurement.
    • PI Film: Prices stable; domestic alternatives emerging. Recommend monitoring domestic Kapton film mass-production progress before making procurement decisions.

  • 2026-04-23 价格趋势日报

    价格概览表

    材料 当前价格区间 周环比 趋势
    PTFE悬浮树脂（中粒） 4.7-5.4万元/吨 持平 → 稳定
    PEEK树脂（工业级） 30-50万元/吨 -3%~0% ↓ 小幅下行
    PEEK树脂（医疗级） 80-100万元/吨 持平 → 稳定
    碳纤维（T300/T700通用级） 84-90元/kg +3.1% ↑ 触底回升
    碳纤维原丝 3.7万元/吨 +41% ↑↑ 急涨
    PI薄膜（电子级） 180-500元/㎡ 持平 → 稳定
    氧化铝（期货） 2601-2675元/吨 -2.6% ↓ 小幅回调
    氧化锆粉体（工业级） 28-30元/kg 持平 → 稳定

    重点变动

    • 碳纤维原丝：+41% — 4月9日碳纤维原丝价格单日暴涨41%，突破3.7万元/吨。恒神股份率先调价，每吨上调5000-10000元，吉林系、上海系及日本东丽紧随其后。本轮涨价由丙烯腈成本推动叠加行业供需格局逆转驱动，2026年Q1碳纤维均价同比上涨3.07%，结束三年连跌趋势。
    • PTFE悬浮中粒：持平 — 隆众资讯4月17日报价4.7-5.4万元/吨，鲁西化工近期曾下调1000元/吨至3.4万元/吨，但整体市场仍以稳为主，供给端暂无重大变动。
    • PEEK工业级：小幅下行 — 国产PEEK价格已从高峰80-120万元/吨降至30-50万元/吨，国产化率从2020年18%升至42%，2026年政策目标60%。国产替代加速推动工业级价格持续下探，但医疗级价格仍坚挺在80-100万元/吨。
    • 氧化铝期货：-2.6% — 氧化铝期货AO2605周内收2673元/吨，周跌幅2.6%。供应端产能释放、库存宽松是主因，资金观望情绪浓厚。

    影响分析

    对采购成本的影响

    • 碳纤维原丝暴涨将传导至碳纤维成品，风电叶片、储氢瓶等下游成本压力上升。T800及以上高端品仍供不应求，价格弹性更大。
    • PEEK国产替代红利持续释放，工业级采购成本有望进一步下探，对半导体、汽车零部件企业是利好。
    • 氧化铝走弱对特种陶瓷原料端形成成本支撑减弱，但粉体加工环节价格传导滞后，短期影响有限。

    对供应链的影响

    • 碳纤维涨价可能引发下游客户提前锁定订单，短期需求脉冲叠加供应弹性不足，Q2价格中枢有望进一步上移。
    • PI薄膜市场电子级需求稳定（FPC、电池隔膜），国产Kapton替代品逐步放量，进口依赖度持续下降。

    行动建议

    建议锁定价格的材料

    • 碳纤维：原丝暴涨信号明确，成品跟涨确定性强，建议Q2提前锁定T700及以下通用级订单量。
    • PTFE悬浮中粒：虽然当前稳定，但氟化工产业链受环保限产影响，下半年供给收缩风险存在，建议适度备库。

    建议观望的材料

    • PEEK工业级：国产替代加速中，价格仍有下行空间，不急于锁量，可采用小批量多频次采购策略。
    • 氧化铝：期货持续走弱，供给宽松格局未改，可等待更低价位再行大单采购。
    • PI薄膜：价格平稳，国产替代品逐步推出，建议跟踪国产Kapton膜量产进度后再做决策。

    | 氮化硅粉体（工业级） | 420-700元/kg | 持平 | → 稳定 |

    **重点变动**

    – 碳纤维：+3.1%，触底反弹信号明确。2026年Q1季均价较去年同期涨3.07%，3月参考价回升至84元/kg。山东永成宣布5月起全线涨价10%，吉林化纤各规格上调5,000元/吨。丙烯腈原料价格大幅上涨为碳纤维成本端提供强力支撑。风电叶片、航空航天、低空经济等领域需求持续增长，高端T800及以上级别碳纤维供不应求。
    – PTFE树脂：鲁西化工报价下调至34,000元/吨，周降1,000元/吨。中粒主流报价4.7-4.9万元/吨，分散树脂5.4万元/吨持稳。行业产能充裕，下游需求偏弱，短期价格承压。
    – PEEK树脂：国产替代加速推进，国产化率已从2020年的18%提升至42%，政策目标2026年达60%。国产工业级PEEK价格降至30-50万元/吨，较进口80-120万元/吨差距显著缩小。全球PEEK市场预计以20.26%年复合增长率扩张，2032年达326亿元。
    – 氧化铝：冲高回落，期货主力合约较3月高点3,136元/吨回调超14%至2,695元/吨。现货均价2,774元/吨，涨幅缩窄至0.8%，市场观望情绪升温。
    – PI薄膜及氮化硅粉体：价格整体平稳，PI薄膜受FPC/新能源需求支撑维持高位，氮化硅粉体供应格局稳定，价格区间未现明显波动。

    **影响分析**

    – 采购成本：碳纤维涨价预期将对风电、储氢瓶、3D打印等行业采购成本造成5-10%上浮压力；PEEK国产替代则持续为下游降本提供红利；PTFE降价有利于密封件、防腐管道等领域降低原料支出。
    – 供应链：碳纤维原丝价格同步上涨（12K原丝37,000元/吨、24K原丝34,000元/吨），产业链自上而下传导涨价信号，需关注5月调价落地后的实际执行情况。氧化铝价格回落有利于陶瓷基板、耐火材料等下游成本改善。

    **行动建议**

    – 🔒 建议锁定价格：碳纤维——涨价信号密集，5月多家厂商调价在即，建议提前锁单或增加库存；PEEK国产料——国产替代窗口期，价格处于下降通道，适合推进国产替代采购。
    – 👀 建议观望：PTFE——产能过剩短期难改，价格仍有下探空间，可推迟批量采购；氧化铝——期货回调未止，等价格企稳后再做决策。
    – ✅ 按需采购：PI薄膜、氮化硅粉体——供需平稳，无急涨急跌预期，正常按需采购即可。
