## Segment Deep Dive
### 1. PTFE: Commodity Grades Flat, Electronic Grade Structurally Strong
**Price**: Per Fluorine Online (Oct 4), PTFE suspended medium-grain RMB 43,000/ton, dispersion resin RMB 44,000/ton, dispersion emulsion RMB 28,000/ton — all flat WoW. Commodity-grade supply remains loose with no directional breakout.
**Structural opportunity**: AI compute infrastructure is driving high demand for electronic-grade PTFE (low-dielectric resin for high-frequency CCL). The price spread between electronic and commodity grades keeps widening.
**Action**: Commodity resin is a buyer’s market — restock in phases on dips. Watch the qualification window for electronic-grade PTFE in high-frequency copper-clad laminate supply chains.
### 2. PEEK: Humanoid Robot Engine Keeps Igniting
**Price**: Domestic pure resin RMB 320-380k/ton. Market quotes: Zhongyan 770CA30 (30% CF) RMB 568/kg, Victrex 90G RMB 680/kg, Evonik L4000G RMB 520/kg, pure resin 450G ~RMB 560/kg.
**Core driver**: Each humanoid robot uses ~5-7 kg of PEEK; every 1 million robots adds 6,600-6,900 tons of demand. eVTOL and semi-solid-state battery thermal management support premium grades. Domestic 10,000-ton capacity (Ningbo Huaxiang 12,000t) landing widens domestic cost-performance advantage.
**Action**: Robot supply-chain qualification takes 3-5 years — early binding with head OEMs is valuable. Buy domestic resin as needed; time imported premium grades around FX windows.
### 3. Carbon Fiber: Bottom Confirmed, a “Divergent Pricing” Cycle Begins
**Price**: Longzhong (Sep 30): Jilin Chemical Fiber wet-spun 3K at RMB 220/kg, Guotai Dacheng T700 12K at RMB 135/kg incl. tax — stable for two straight weeks; T300 12K ~RMB 80/kg. Acrylonitrile average price up 8-10% YoY in 2026, providing firm cost support.
**Trend**: The industry is exiting its “price war” and entering value-return with divergent pricing: T300 12K expected at RMB 75-85/kg, T700 12K at RMB 140-160/kg, and aerospace-grade T800+ small-tow holding at RMB 220-260/kg. EV lightweighting (2026 demand 13,000t, +25%) and hydrogen storage vessels (8,000t) form the new growth poles.
**Action**: Buy industrial T300/T700 large-tow on dips; lock T800+ premium grades for 3-6 months — tight supply persists.
### 4. Specialty Ceramics: Aluminum Nitride Is the Tightest AI Thermal Material (Today’s Top Story)
**Key event**: AI compute hardware iteration has pushed telecom-grade aluminum nitride (AlN) powder to **RMB 280-320k/ton**, a clear step up from prior years. With 170-230 W/m·K thermal conductivity, AlN is a must-have substrate for 1.6T optical modules, HBM advanced packaging, and AI server thermal management.
**Supply-demand**: China’s AlN powder gap was 1,950t in 2022, projected to widen to 3,100t by 2025. Rare-earth export controls have cut overseas head producers’ capacity by 25-30%, stretched lead times beyond 24 weeks, and backlogged high-end substrate orders into late 2027. Domestic substitution is accelerating across the board.
**Other moves**: Metallurgical alumina weak at ~RMB 2,673/ton; Sinocera’s sulfide solid-state electrolyte line completed, with its new-energy materials segment posting H1 revenue of RMB 339M (+56.5%) at 34.7% gross margin.
**Action**: 🔒 Lock prices now on AlN powder and high-end silicon nitride; with overseas lead times deteriorating, prioritize domestic suppliers already qualified by semiconductor customers.
### 5. Electronic Chemicals: The Photoresist Localization Breakout Year
**Market size**: China photoresist market reached RMB 19.806B in 2025 (+23.2%); 2026’s three segments (IC RMB 7.79B, display RMB 8.08B, PCB RMB 6.12B) total ~RMB 22B. Wet chemicals are projected at RMB 25.71B in 2026 (2025: RMB 25.4B, +11.5%) on 4.90M tons of demand.
**Localization**: ArF localization is below 5% — consensus holds that 2026 is the “photoresist breakout year”. Dinglong’s 330-ton KrF/ArF capacity in Qianjiang landed, with 8 products winning batch orders from mainstream fabs in H1; Nata Opto’s ArF passed SMIC qualification with small-batch supply; Chengzhi (Tonda) self-produces KrF resin at 35% below import cost. G5 wet chemicals remain below 20% localized; Xingfu Electronics Q1 revenue +36.7%.
**Action**: Tightening overseas high-end photoresist supply plus accelerating domestic qualification is the highest-certainty localization window. Track ArF mass-production announcements and G5 wet-chemical adoption.
### 6. Aerogel: Regulatory Mandate Plus European Ramp — Twin Engines
**Market size**: Global aerogel ~USD 1.85B in 2026 (+22%); China est. RMB 4.5-8.5B (+18.5%), with nano-porous aerogel insulation exceeding RMB 12B. EV battery aerogel insulation sheets surpass RMB 1.2B at a 25%+ CAGR.
**Latest**: Aspen Aerogels in August doubled its 2026 European thermal-barrier revenue guidance to **USD 20-30M** (from 10-15M) as European OEMs move from pilots to series production. GB38031-2025 (in force since July 1) upgrades battery thermal-propagation requirements to “suppress propagation,” making aerogel sheets standard in premium packs. China capacity exceeds 500,000 m³; ambient-pressure drying cuts costs another 20-30%.
**Action**: Automotive-grade aerogel sheets are backlogged post-regulation — lock capacity early. Low-end commodity blankets are commoditized and price-competitive; buy as needed.

## Impact Analysis
– **Procurement costs**: Upward channels are clear for AlN, PEEK and high-end carbon fiber — raise budgets 5-10%; commodity PTFE and industrial carbon fiber are buyer’s markets — restock on dips.
– **Supply chain**: AlN overseas lead times exceed 24 weeks with orders backlogged into late 2027 — domestic substitution is the most urgent supply-chain rebuild; photoresist qualification is the highest-certainty replacement window.
– **Content marketing**: AlN AI thermal management, ArF photoresist localization, and aerogel GB38031 compliance are the three highest traffic-plus-conversion topics right now.
## Action Summary
– 🔒 **Lock in now**: AlN powder (AI thermal shortage), automotive-grade aerogel sheets, T800+ carbon fiber
– ⏳ **Buy on dips**: Commodity PTFE resin, industrial T300/T700 large-tow carbon fiber
– 📋 **Monitor**: Q4 fluorochemical pricing policy, carbon fiber head-makers’ hike pass-through, ArF photoresist mass-production announcements, pace of domestic AlN capacity release
