    PI Film (Electronic Grade) 180–475 CNY/kg 0% → Stable
    Alumina (Ceramic Grade) 2,695–2,774 CNY/ton -0.8% ↓ Under Pressure

    Key Movements

    Carbon Fiber: +3.1% — The standout this week. Jilin Chemical Fiber announced a price increase of 5,000 CNY/ton across all carbon fiber specifications in early April, driven by surging acrylonitrile feedstock prices. Kaiyuan Securities notes that T800+ high-end grades remain in tight supply-demand balance, with robust demand from wind turbine blades, aerospace, and the low-altitude economy. Q1 2026 average carbon fiber prices rose 3.07% YoY. The carbon fiber concept index gained 0.47%–0.63% this week.

    PTFE: -2.9% — Luxi Chemical lowered its PTFE quote to 34,000 CNY/ton, down 1,000 CNY/ton from the prior period. Domestic PTFE capacity expansion combined with sluggish demand continues to pressure prices. However, dispersion resin (Fuxin Hengtong at 54,000 CNY/ton) remains relatively firm, and imported brands (Daikin, Chemours) hold steady at 120–180 CNY/kg.

    PEEK: +1.3% — The PEEK concept index edged up 1.34%. Virgin resin (Victrex 450G) is quoted at 880 CNY/kg, while the 600G grade reaches 980 CNY/kg. Domestic modified PEEK trades in the 280–350 CNY/kg range with balanced supply and demand.

    PI Film: Stable — No significant price movement for electronic-grade PI film. Domestic products range from 180–475 CNY/kg, while premium imports like DuPont KAPTON exceed 2,000 CNY/kg. FPC and new energy demand supports the price floor.

    Alumina: -0.8% — Spot average price around 2,774 CNY/ton, pulling back from recent highs. The futures front-month contract dipped to 2,695 CNY/ton, down over 14% from the March peak. The alumina oversupply pattern persists, with new capacity continuing to come online as the main downward pressure.

    Impact Analysis

    Cost Side: Rising acrylonitrile prices are the core driver of carbon fiber price increases; crude oil volatility indirectly affects PTFE and PEEK cost structures; for alumina, Guinea policy uncertainty remains the biggest supply-side variable.

    Demand Side: Emerging sectors like low-altitude economy and aerospace are driving rapid demand growth for high-end carbon fiber (T800+); semiconductors and new energy continue to pull PI film and specialty ceramics demand; PTFE demand remains weak, with slower procurement in wire & cable and chemical corrosion protection.

    Supply Side: PTFE and alumina overcapacity is unlikely to reverse in the short term; high-end carbon fiber grades face supply tightness, with domestic substitution accelerating but high-end capacity still limited; PEEK domestic players like Jilin Zhongyan are expanding, but import dependency remains high.

    Actionable Recommendations

    Lock-in Prices:

    • Carbon Fiber (T700/T800) — Strong cost support + robust demand; further upside expected. Recommend locking in long-term contracts.
    • Imported PEEK Resin — Tight supply pattern; recommend advance stocking.

    Stay on the Sidelines:

    • PTFE Suspension Resin — In a downtrend; no rush to purchase, wait for bottom signals.
    • Alumina — Oversupply persists; further downside expected.

    Monitor Closely:

    • Jilin Chemical Fiber carbon fiber price increase implementation and industry follow-through

    Price Overview

    Material Current Price Range (CNY/ton) WoW Trend
    PTFE Resin (Medium Granule) 34,000 – 54,000 -2.8% ↓ Slight Decline
    PEEK Resin (General Grade) 350,000 – 500,000 0% → Stable
    Carbon Fiber (T700/12K) 120,000 – 180,000 +3.1% ↑ Moderate Increase
    PI Film (Electronic Grade) 200,000 – 400,000 +1.5% ↑ Slight Increase
    Alumina (Metallurgical Grade) 2,670 – 2,720 +2.7% ↑ Futures-driven
    Silicon Nitride Powder 145,000 – 300,000 0% → Stable

    Key Movements

    • PTFE Resin: -2.8% — Luxi Chemical lowered its offer to 34,000 CNY/ton, down 1,000 CNY/ton. Domestic fluoropolymer capacity continues to expand while downstream demand from sealing and tubing remains flat, creating a supply surplus. Longzhong Info reports PTFE medium granule at 47,000 CNY/ton. Premium imports (Daikin, DuPont) remain firm at 130-135 CNY/kg.
    • Carbon Fiber: +3.1% — Q1 2026 average price rose 3.07% YoY, supported by sharp increases in acrylonitrile costs. CITIC Securities identifies three drivers: rising costs, tight supply of high-end grades, and domestic technology breakthroughs. T800+ grades remain in persistent shortage. Demand from wind turbine blades, aerospace, high-pressure hydrogen storage, and low-altitude economy is growing rapidly.
    • Alumina: +2.7% (Futures) — The April 27 futures contract closed at 2,899 CNY/ton, up 2.66%, driven by rumors of Guinea bauxite export cuts. Spot prices remained flat at 2,670-2,720 CNY/ton in South/East China. Warehouse receipts near 465,000 tons (historical high) and total inventory exceeding 5.9 million tons maintain the oversupply narrative. The widening futures-spot spread limits further upside.
    • PEEK Resin: Stable — Victrex 450G quoted at 65-880 CNY/kg depending on specifications. Medical-grade PEEK saw price reductions under volume-based procurement but significant volume growth — Kuantu Medical reported 10.01% revenue growth in PEEK products for 2025, with share rising to 66.23%. Industrial-grade bulk prices remain stable as domestic substitution accelerates.
    • PI Film: +1.5% — DuPont 300HN quoted at ~2,000 CNY/kg; domestic electronic grades range 13-475 CNY/kg. Demand from lithium batteries and flexible printed circuits continues to pull high-end PI film consumption upward. Domestic substitution is progressing steadily.

    Impact Analysis

    Procurement Cost Impact

    • Continued carbon fiber price increases will raise raw material costs for wind energy and composite manufacturers, with T700-grade procurement costs up ~3% YoY
    • PTFE price decline benefits seal and tubing manufacturers — consider increasing purchase volumes
    • Alumina futures volatility has not materially impacted specialty ceramic raw material costs as spot prices remain stable

    Supply Chain Impact

    • High-end carbon fiber (T800+) supply-demand imbalance unlikely to resolve short-term — recommend locking in long-term supply contracts
    • PEEK domestic substitution is accelerating with new capacity coming online, helping shorten lead times and reduce costs
    • Guinea bauxite policy uncertainty adds risk to the alumina supply chain — monitor closely

    Actionable Recommendations

    Lock-in Pricing

    • Carbon Fiber T700/T800 — Acrylonitrile cost support + high-end tight balance; upward trend confirmed. Recommend quarterly fixed-price contracts.
    • PI Film (Electronic Grade) — Battery/FPC demand growth driving moderate price increases. Recommend advance stockpiling.

    Hold and Watch

    • PTFE Resin — Capacity expansion + soft demand; further downside possible. Purchase on-demand, avoid bulk price-locking.
    • Alumina — Futures driven by news but spot stable with high inventories. Wait for Guinea policy clarity before committing.
