Key Movements
- PTFE suspension mid-particle: +1.5% — Upstream feedstock (fluorspar, HF) prices rose; Haohua Science & Technology disclosed on Aug 3 that PTFE selling prices have increased. At ~RMB 32,000/t, the grade remains near a three-year low, with cost support building.
- Carbon fiber T300/T700: +1.0% — Toray raised its TORAYCA carbon fiber, prepreg, fabric and laminate prices by 10%–20% from Jan 2026; Jilin Chemical Fiber hiked 12K and 3K by RMB 5,000 and RMB 10,000 per tonne respectively. Industry inventories have fallen from highs and the supply-demand balance is improving.
- PEEK resin: +1.0%–1.5% — Demand from robotics, low-altitude economy and eVTOL lightweighting is expanding; annual demand growth is ~14%–17%. Domestic substitution capacity surpassed 10kt in 2026 and share is heading toward 60%, keeping the price center firm-to-higher.
- PI film: standard stable, high-end firm — Supported by 5G, flexible displays and new-energy demand, with accelerating domestic substitution; ample standard-grade supply caps gains.
- Specialty ceramic raw materials: alumina slightly up, zirconia/silicon nitride stable-tight — Chalco reported minor regional increases in early June; high-purity powders are supported by electronics and new-energy ceramic demand.
Impact Analysis
Procurement cost: PTFE and carbon fiber, driven by costs and leader price hikes, posted ~1%–1.5% WoW cost increases; PEEK stays elevated, pressuring high-end BOM; specialty ceramic raw materials are broadly stable with limited cost impact.
Supply chain: Carbon fiber upstream hikes have passed through to prepreg and fabric, so aerospace and wind-power buyers should guard against lead-time volatility; PTFE dispersion resin inventories are low with tightness in some grades; PI film high-end domestic yield is improving, opening an import-substitution window.
Action Recommendations
Lock prices: Carbon fiber (T700 and above is tight with strong pricing power) and PTFE dispersion resin (low inventory, cost-push makes upside likely) — use quarterly framework agreements or forward pricing.
Hold/watch: PEEK (capacity additions and substitution will weigh on price — buy in batches opportunistically), standard PI film and alumina (ample supply, no near-term surge driver — maintain just-in-time purchasing).
