Key Movements
- PTFE Resin: Weakly stable (±0%). The national benchmark for suspension mid-grade stands at 43,000 CNY/t (Longzhong, Aug 20, flat), yet low-end quotes from Shandong Yihe are 31,800 CNY/t while high-end Hongyang reaches 45,500 CNY/t — a 43% intra-month spread. Upstream, anhydrous HF has climbed to 14,700-16,500 CNY/t (+40% YTD), strengthening producers’ price-support stance, but a downstream off-season and high inventories cap the rebound.
- PEEK Resin: Stable to slightly weak (flat). Domestic virgin resin is 300k-400k CNY/t; imported (Victrex, etc.) 550k-1,000k CNY/t. The earlier surge driven by humanoid-robot demand hype has cooled; continued domestic capacity ramp-up (Zhongyan, Jida, etc.) plus import substitution has rebalanced supply and demand.
- Carbon Fiber: Bottoming out and recovering (↗). Jilin T300/12K ~100 CNY/kg, T300/25K ~90 CNY/kg, +5.3%/+5.9% MoM; T700/12K Jiangsu 105 CNY/kg flat, major-mill offer 135 CNY/kg. The sector has ended a half-year decline; costs at 114,145 CNY/t (+3.2% MoM) while gross margin remains negative (-10,002 CNY/t), so the rise is largely corrective.
- PI Film: Confirmed uptrend (↑, +1% to +2%). Electrical-grade uniaxial 110-170 CNY/kg, biaxial 170-220 CNY/kg; electronic grade 200-500 CNY/kg. Kaneka’s 20% hike (effective April) keeps transmitting, backed by PMDA/ODA cost support and AI-server / foldable-screen demand; the global gap is ~20,000 t and overseas orders are locked through 2027.
- Specialty Ceramic Raw Materials: Divergent. Alumina (metallurgical grade) 2,700-2,800 CNY/t, -1% WoW, weak; fused zirconia ≥33,000 CNY/t, +26.7% YTD, with Guoci raising zirconia powder prices 10%-40% from Jul 27, driven by rising zircon sand (+17% YTD), yttria export controls, and Tosoh’s supply halt (~6,000 t/yr gap).
Impact Analysis
- On procurement cost: Rising PI film and zirconia prices directly lift costs for electronic packaging, dental, MLCC and PCB grinding media; PTFE and carbon fiber remain low and cost-controllable; slightly lower alumina is marginally favorable for refractories / ceramics.
- On supply chain: PI film and high-end zirconia are seller’s markets with extended lead times, requiring early order-locking; carbon fiber localization improves resilience; PTFE faces periodic tightness from upstream fluorochemical maintenance.
Action Recommendations
- Lock prices: Electronic-grade PI film, fused zirconia and yttria stabilizers — uptrends are clear and supply gaps will not close soon; adopt medium-term framework or volume / price locks.
- Hold / monitor: PTFE resin (weakly stable, await cost-pass-through confirmation), PEEK resin (suppressed by import substitution, slightly weak), alumina (declining trend). Carbon fiber can be built up in batches on dips.
