Key Movements
- PTFE Resin: General grade +2%, electronic grade +5%. NVIDIA adopted PTFE as the core material for its Rubin Ultra orthogonal backplane, driving surging AI-computing demand. Combined with rising fluorspar/hydrofluoric-acid costs and the industry’s “volume-control, price-protection” stance, the price center keeps climbing; high-end electronic-grade PTFE has exceeded RMB 150k/t.
- Carbon Fiber: Zhongfu Shenying disclosed on Sept 7 that it raised all product lines by 5%–10% starting in August — a strategic price calibration after half a year. Toray raised prices 10%–20% from January and Jilin Chemical Fiber followed. The core driver is acrylonitrile costs pressured by high, volatile international crude (Brent ~US$90/bbl); the company’s raw-material purchase cost rose 13.6% YoY in a single quarter, confirming a bottom reversal.
- Specialty Ceramic Raw Materials (Zirconia): General zirconia is up 29% YTD to RMB 56k/t; Sinocera raised powder prices 10%–40% from July 27; high-end fused zirconia touched RMB 33.5k/t. Zircon sand stays high (65% grade RMB 11.9k–12.5k/t), yttria export controls lifted YSZ costs, and demand from PCB grinding media, MLCC, and solid-state batteries is converging.
- PEEK Resin: Prices stable. Domestic players (Zhongyan, Junhua) keep expanding, and substitution is pressing down mid/low-end prices; imported Victrex and other high-end grades stay elevated at RMB 800–1,500/kg on tight supply.
- PI Film: Electrical grade (RMB 110–220/kg) steady; electronic grade +2%. Kaneka raised all PI film prices 20% in April; the global electronic-grade PI film supply gap is locked through 2027, with AI servers, advanced packaging, and foldable displays driving high-end demand.
Impact Analysis
- Procurement cost: PTFE, zirconia, and high-end PI film keep rising, lifting budgets for fluoropolymer and functional-ceramic products (recommend +5%–10% uplift); carbon fiber and PEEK supply is ample, keeping overall cost pressure contained.
- Supply chain: High-end PI film and high-end zirconia are highly import-dependent; overseas supply cuts and long-term lock-ins by major customers tighten supply elasticity — watch FX and geopolitical logistics risks. Carbon fiber and PEEK have ample domestic supply, improving buyer leverage.
Actionable Recommendations
- Lock in now: PTFE (especially electronic grade), high-end electronic PI film, yttria-stabilized zirconia — clear upward trend; sign 3–6 month contracts to lock prices.
- Watch / hold: PEEK industrial grade (domestic expansion pressing prices, buy opportunistically in batches); carbon fiber T300 (bottom-range oscillation, build positions in batches, no need to chase highs).
