Advanced Materials Price Trend Daily Report (2026-10-13): Markets Hold Steady, PI Film Q4 Price-Hike Odds Rising

Price Overview

Key Price Movements

• PI Film: Flat, but Q4 price-hike odds rising markedly. South-China electrical grade 25μm: uniaxial ¥130–170/kg, biaxial ¥190–220/kg, quotes flat for four straight weeks (Shandong is cheaper: uniaxial ¥110–140, biaxial ¥170–190/kg). However, upstream DMAC has surged since September (major plant maintenance + rising acetic acid), while PMDA/pyromellitic dianhydride has climbed to ¥44,000–45,000/ton, up 22–26% MoM. Film producers’ margins are nearing inversion. If feedstock momentum continues, electrical-grade PI film prices are likely to follow upward in Q4.

• Aluminum Nitride Powder: +2% (AI thermal-management shortage persists). Communication-grade AlN powder holds at ¥280,000–320,000/ton. Rare-earth export controls have cut overseas top producers’ capacity by 25–30%, with lead times beyond 24 weeks and high-end substrate orders backlogged into late 2027. China’s powder gap is estimated to widen to 3,100 tons in 2025. Demand from AI compute hardware (1.6T optical modules, HBM packaging, AI server thermal management) keeps growing structurally, accelerating domestic substitution.

• PTFE Resin: Flat (commodity weak, electronic strong). Longzhong’s Oct 10 report: PTFE medium-grain mainstream at ¥41,000–43,000/ton; Zhonghao Chenguang suspended medium-grain ex-works at ¥48,000/ton; low-end Shandong spot at ¥31,800/ton — the market is broadly sideways. Operating rates at 60–70% with soft downstream demand. Electronic-grade PTFE, driven by AI compute infrastructure (high-frequency high-speed CCL), holds above ¥150,000/ton, with the spread vs commodity grades still widening.

• PEEK Resin: +0.3% (robot demand underpins pricing). Domestic pure resin firm at ¥320–380/kg, with mainstream trader quotes clustered around ¥350/kg. The first year of humanoid-robot mass production (5–7 kg per unit) and EV 800V platform demand support prices, while domestic capacity releases cap the upside.

• Carbon Fiber: Flat (value-recovery cycle continues). T700 12K holds at ¥135/kg (tax-incl., ex-works) for a third straight week; T300 12K ~¥80/kg. Acrylonitrile up 8–10% YoY provides firm cost support. The industry has exited its price war and entered a “value-return plus divergent pricing” cycle; high-end small-tow (T800+, ¥180–240/kg) remains in short supply.

Impact Analysis

• On Procurement Costs: The PI film locking window is closing — with PMDA up over 22% MoM, a Q4 follow-up hike of 5–10% on electrical-grade film is plausible; confirm Q4 quotas before producers move. AlN overseas delivery delays may lift spot premiums by 10–15%. Crude oil remains elevated near $97/barrel on average, but the price-adjustment rate has turned negative (-4.65%); China’s Oct 15 fuel-price window is expected to cut retail prices by ¥270/ton, marginally easing chemical cost pressure.

• On Supply Chain: AlN overseas lead times now exceed 24 weeks — supply risk is concentrated in high-end electronic grades; prioritize domestic powder suppliers already qualified by semiconductor customers. PTFE and PI film supply is loose; industrial-grade carbon fiber is ample while high-end small-tow stays tight. The PEEK supply chain is stable; premium imported grades carry FX exposure.

Action Recommendations

• Lock in: PI film (Q4 hike odds rising — secure quotas before prices move); aluminum nitride powder (structural shortage — lock volume and pricing during the domestic-substitution window).
• Lock in: Carbon fiber T700 and above (cost support + value recovery; prices likely to hold firm or rise short term — lock 3–6 months of volume).
• Watch: PTFE commodity grades (buyer’s market; restock in phases on dips); electronic-grade PTFE requires early qualification-queue planning.
• Procure as needed: Domestic PEEK resin and calcined alumina (stable pricing; match purchases to production schedules).
