Key Movements
- PTFE Resin: Suspension medium-particle +1.5%. Upstream feedstock (fluorspar, hydrofluoric acid) remains elevated — hydrofluoric acid is up +44.77% YoY and fluorspar +5.46% MoM — and producers are holding prices firm. After a sharp +30% spike in July, the gain has narrowed markedly, entering a high-level consolidation. Dispersion resin supply-demand is balanced and prices are steady.
- Carbon Fiber: T300/T700 both +1.0%. Toray raised its TORAYCA series 10%–20% from Jan 2026, with Jilin Chemical Fiber following; the key feedstock acrylonitrile hit a multi-year high in August (~RMB 11,700/t at East China ports), giving clear cost-push support. Industry inventories have fallen from their highs and a bottom-recovery signal is confirmed.
- PEEK Resin: +1.0%~1.5%. Lightweighting demand from robotics, the low-altitude economy and flying cars is ramping up, with annual demand growth of ~14%–17%; domestic substitution capacity surpassed 10kt in 2026 and its market share is heading toward 60%, lifting the price center steadily.
- PI Film: Standard grades stable, high-end firm. Demand from 5G, flexible displays, new energy and AI-server thermal management supports the market and domestic substitution is accelerating; however, ample supply of standard grades caps gains, while high-end electronic/semiconductor grades remain firm on a supply gap (globally ~10kt).
- Specialty Ceramic Raw Materials: Alumina +0.5%. Bauxite cost support is strengthening but the overall oversupply structure remains, limiting upside; high-end powders such as silicon nitride and zirconia are stable-to-tight, buoyed by new-energy and semiconductor demand.
Impact Analysis
- Procurement cost: After its earlier sharp rise, PTFE sits at a relatively high level for the past three years, pressuring costs for anti-corrosion linings and seals — lock in 2–3 months of inventory. Carbon fiber’s bottom recovery will push composite material costs mildly higher over the medium term. High-end PI film stays firm — place orders 3 months ahead. Specialty ceramic raw materials are overall benign, with limited cost impact.
- Supply chain: PTFE’s fluorspar supply cannot be eased near-term and supplier lead times are lengthening (raise inventory buffer from 30 to 45 days). Carbon fiber localization exceeds 86%, improving autonomy but intensifying price competition. High-end PI film remains highly dependent on imports (DuPont, Kaneka, UBE, SK); under geopolitical/trade friction, supply-disruption risk outweighs price risk — dual sourcing is advised for critical programs.
Action Recommendations
- Lock in now: ① PTFE resin (cost-push and tight supply — lock 2–3 months of volume immediately); ② Carbon fiber T700 (bottom recovery confirmed — sign Q3–Q4 long-term contracts); ③ High-end/semiconductor PI film (supply gap locked through 2027 — order 3 months ahead).
- Hold and watch: ① Domestic standard-grade PEEK (capacity expansion caps prices — procure in batches opportunistically); ② Standard electronic-grade PI film and alumina (ample supply, no near-term surge driver — maintain just-in-time purchasing).
