## 1. PTFE: Weak but Stabilizing, Electronic Grade Is the Strongest Structural Play
**Latest prices**: PTFE suspended medium-grain mainstream ¥42,000-44,000/ton, flat WoW; fine powder ¥46,000-48,000/ton; dispersion ¥27,000-29,000/ton; FEP cable grade ¥49,000-51,000/ton. Imported grades (DuPont MP1200 powder ~¥135/kg, Daikin MG-1050F ~¥178/kg) carry a wide premium over domestic supply.
**Market read**: Anhydrous HF staying high and rising chloroform offer cost support, but the R22 price cut in September weakened overall support — cost pressure still cannot be passed downstream. Operating rates hold at 60-70%, maintenance units are restarting, spot supply is ample, and downstream demand is only narrowly recovering at the tail of the off-season.
**Opportunity**: AI compute infrastructure keeps pushing high-frequency high-speed CCL upgrades along the PTFE path. Electronic-grade PTFE has broken through ¥150,000/ton, with the gap versus commodity grades still widening. High-end applications such as NVIDIA Rubin Ultra orthogonal backplanes are the new value anchors.
## 2. PEEK: Humanoid Robots + Domestic Substitution, Twin Engines
**Latest prices**: Domestic pure resin ¥320,000-380,000/ton, stable; GF/PEEK ¥400,000-700,000/ton; graphite/PTFE wear-resistant grades ¥400,000-600,000/ton; medical implant-grade high-purity PEEK ¥1.5-2.45M/ton (gross margin 60%+). Imported Victrex 450G ~USD 90-110/kg; leading Chinese grades about half that.
**Core driver**: Each humanoid robot uses 6.6-6.9kg of PEEK — the robot lightweight-skeleton demand engine keeps firing. Domestic capacity releases (Zhongyan, Junhua etc.) suppress low/mid-end prices and accelerate downstream adoption.
**Trend**: Global PEEK market 2026E USD 1.25-1.8B; China CAGR ~40%. Medium-high competition with large headroom for content marketing.
## 3. Carbon Fiber: Bottom Reversal Confirmed, High-End Structurally Tight
**Latest prices**: T700/12K mainstream ~¥105/kg, with taxed premium offers up to ¥135/kg; T300/25K ~¥90/kg; 3K small-tow ¥220/kg. Industry margin is still negative (~-¥8,000/ton), but leading producers have hiked 5%-10% across grades — a clear reversal signal.
**Fundamentals**: Inventory 13,270 t (+0.45% WoW); August capacity utilization 70.1%; low/mid-end destocking continues. 48K large-tow average price back to ~¥70/kg, lowering industrial adoption thresholds.
**Opportunity**: Humanoid robots (5-7kg per unit), eVTOL and commercial space pull T800+ demand, where certification barriers hold pricing firm. Domestic capacity exceeds 100,000 t with 86% localization and a 20-30% cost advantage.
## 4. Specialty Ceramics: Low-End Oversupply vs. High-End Boom
**Market data**: China advanced ceramic components market ¥18.5B in 2026 (+14.2%); global precision ceramics USD 18.5B (+6.8%). Alumina holds ~38% share, while zirconia and silicon nitride grow 18.5% and 22.3% respectively.
**Demand structure**: Semiconductor equipment accounts for 32% of component consumption, EV power/thermal management 28%. AlN high-thermal-conductivity substrates and Si3N4 high-temperature parts are accelerating domestic qualification — multiple producers have entered batch validation for AlN powders.
**Opportunity**: New functional ceramics (solid-state battery separator coatings, PV wire-saw busbars) are at the early growth stage with 25%+ CAGR over the next three years. The Yangtze River Delta contributes 45% of national output; top-10 concentration edges up to 41.5%.
## 5. Electronic Chemicals: Photoresist Substitution Enters the Deep-Water Zone
**Market data**: Global electronic chemicals 2026E USD 89.17B (+10.8%); China above ¥235B. Domestic semiconductor photoresist market ~¥11.8B in 2026 (+21% YoY).
**Key progress**: KrF localization 40-45%; ArF below 1% — but Dinglong’s ArF photoresist has reached a 92% yield, breaking the Japanese monopoly. Electronic specialty gas localization 40-45% with tungsten hexafluoride above 75%. High-frequency high-speed resins upgrade along BMI→PPO→hydrocarbon→PTFE paths; electronic-grade PPO import dependence is 90%+, with Dongcai Technology and Shengquan Group breaking through.
**Opportunity**: AI-server PCB evolving from M4 to M8/M8+; global high-frequency high-speed resin market reaches USD 5.07B by 2032 (CAGR 15.1%) — the highest-growth sub-segment.
## 6. Aerogel: Regulation-Driven Volume Ramp-Up Confirmed
**Market data**: China aerogel market ¥8.5B in 2026 (+18.5%), output above 3.5M m³; global market ~USD 1.66B, CAGR 9.9%; EV battery aerogel insulation sheet market tops ¥1.2B (CAGR 25%+).
**Core driver**: GB 38031-2025 mandates “no fire, no explosion” for new vehicle types from July 1, 2026 — cell-to-cell aerogel sheets shift from design option to compliance necessity. Aspen raised its 2026 European thermal-barrier revenue guidance to USD 20-30M in August (Q2 alone: USD 29.5M) as European automakers move from pilots to series production.
**Cost side**: Dry-process maturation cut average production cost ~22% vs. 2023; ordinary aerogel blanket prices are 40% below five years ago, opening civilian applications such as construction boards and insulating coatings.
