2. Segment Intelligence
1. PEEK (Polyether Ether Ketone)
Insight: Humanoid-robot mass production is the strongest growth driver for PEEK. Each humanoid robot uses about 5-7 kg of PEEK (value RMB 3,500-7,500). Global humanoid-robot PEEK demand was ~60-120 t in 2025 and is projected to exceed 12,000 t by 2030 (market size RMB 3-5 bn). Analysts estimate 100k robots drive 195 t of PEEK demand; China’s PEEK market could reach RMB 16.7 bn by 2027 (CAGR above 13%).
Competition: “One dominant leader, several strong challengers.” PEEK + carbon-fiber composites (strength raised to 230-250 MPa) is a key trend in high-end applications.
Action: 1) Target PEEK modified compounds for robot joints/gears/bearings; 2) Track PEEK+CF unidirectional tape capacity (RMB 3,000-5,000/kg); 3) Screen domestic substitution candidates.
2. Aerogel
Insight: Global aerogel market ~USD 1.776 bn in 2025, projected USD 3.304 bn by 2032 (CAGR 9.5%, QYResearch). Tightening EV-safety regulation makes aerogel the “standard firewall” for battery packs; in 2026 a Chinese team mass-produced a 2.3 mm Li-ion thermal barrier rated 1300°C, while LG Chem launched its Nexula® barrier. Process breakthroughs halved costs, shifting the industry from “premium option” to “mandatory scale adoption.”
Competition: Medium. Multi-component aerogels (ceramic nanofiber, graphene aerogel) are R&D hotspots; building insulation and petrochem pipeline markets keep expanding.
Action: 1) Lock in EV-battery thermal-barrier customers; 2) Track low-cost ambient-pressure processes; 3) Build ceramic-nanofiber aerogel portfolio.
3. PTFE (Polytetrafluoroethylene)
Insight: CICC notes surging compute-driven high-frequency/high-speed demand makes electronic-grade PTFE poised for mass adoption; Nvidia Rubin ultra server ramp sparks industry discussion of PTFE orthogonal backplanes, with Shengyi Tech validating. 5G’s low-dielectric/low-loss requirement makes PTFE the inevitable choice. China’s fluorochemical market may exceed RMB 130 bn in 2026.
Competition: Medium-high. High-end segments (semiconductor-grade PFA) rely on imports; Solvay, Daikin, 3M and AGC hold 89% of the high-end PFA market — large substitution headroom.
Action: 1) Enter electronic-grade PTFE film/CCL supply chain; 2) Track high-purity PFA localization; 3) Watch server high-speed cable and backplane materials.
4. Specialty Ceramics (SiC Fiber / Silicon Nitride)
Insight: SiC fiber market projected at USD 3.587 bn by 2026 (10-yr CAGR 34.4%); SiC/SiC ceramic-matrix composites grow from USD 8.8 bn (2021) to USD 25 bn (2031, CAGR 11%), ideal for aero-engine hot sections. China’s 3rd-gen iBN continuous SiC fiber passed expert review in Jun 2026 at world-leading level. Silicon nitride penetrates semiconductor hot zones, PV, storage and hydrogen. Yet ~60% of domestic specialty-ceramic firms lack core tech.
Competition: High. Long certification cycles open a domestic-substitution window.
Action: 1) Track SiC fiber industrialization capacity; 2) Build Si3N4 semiconductor hot-zone parts; 3) Avoid low-end red ocean.
5. Electronic Chemicals
Insight: WSTS (June) projects 2026 global semiconductor market up ~90% YoY to USD 1.511 tn (approx RMB 10.2 tn); memory +249.5% YoY. China’s semiconductor materials market hit USD 9.763 bn in 2024 (+12% YoY, #2 globally). High-end e-materials (large-size Si, SiC, GaN, high-frequency CCL) grow fast; electronic specialty gases expand with localization.
Competition: Medium-high. Oligopoly; low-localization high-barrier segments (wet chemicals, specialty gases, CMP) offer the best openings.
Action: 1) Focus on low-localization semiconductor-material segments; 2) Track HBM/advanced-packaging-driven e-chemical demand; 3) Watch SiC/GaN supporting chemicals.
6. Carbon Fiber
Insight: Carbon fiber heat is steady, but as a reinforcement for PEEK and specialty engineering plastics it benefits from robot light-weighting. T700/T800 CF + PEEK lifts strength to 230-250 MPa for aerospace, defense and robot structures.
Competition: Medium. Civilian oversupply; high-modulus/aerospace grades still imported.
Action: 1) Build high-modulus CF and thermoplastic prepreg; 2) Bind to PEEK-composite downstream (robots, aero-engines).
