Key Price Movements
- PTFE Resin: +30.11% (Strong Rally)
Driven by sustained increases in upstream fluorspar prices, PTFE market prices rebounded sharply. The Chemicalbook index showed a 60% volatility range over 30 days. Shandong suspended medium-particle quotes reached ¥45,500/MT on July 22. Short-term tight supply continues to support prices. - Carbon Fiber T700 (Domestic): -3% (Slight Decline)
On June 28, Zhongfu Shenying put three world-scale carbon fiber production lines into operation simultaneously, rapidly expanding capacity and intensifying market competition. Domestic T700 prices have fallen below the critical ¥100,000/MT level, now 15-20% lower than imported equivalents. Supply-side pressure is evident. - Silicon Carbide (98%): +1% (Slight Rise)
Ningxia-region silicon carbide prices showed a modest upward movement, supported by rising upstream coal prices and environmental production restrictions. Short-term cost support remains firm, with prices expected to remain stable to slightly firm. - Alumina: -2% (Slight Decline)
Xinjiang alumina bidding prices fell approximately ¥50/MT, with port inventories at 629,000 MT (up 2.4% weekly). Shanxi alumina producers face potential production halts due to safety inspections on red mud storage facilities, adding supply-side uncertainty.
Impact Analysis
Impact on Procurement Costs:
- PTFE’s sharp price increase has directly raised costs for chemical anti-corrosion linings and seals — recommend locking in 2-3 months of inventory immediately
- Carbon fiber T700’s continued decline benefits wind turbine blade and aerospace composite procurement — consider extending inventory buffers
- Silicon carbide’s modest rise has limited impact on specialty ceramics and refractory material costs, but monitor Ningxia environmental policy developments
Impact on Supply Chain:
- PTFE: Tight fluorspar supply cannot be resolved short-term; supplier lead times are extending — recommend extending inventory buffers from 30 to 45 days
- Carbon Fiber: Domestic production capacity rising with 90% localization rate reduces import dependency and improves supply chain autonomy, but price competition is intensifying
- PI Film: DuPont and other import brands maintain stable supply; domestic substitution is accelerating
Action Recommendations
| Material | Recommendation | Rationale |
|---|---|---|
| PTFE Resin | 🔴 Lock In Now | 30%+ rally in 30 days with tight supply — lock in 2-3 months immediately |
| PEEK Resin | 🟡 Stock moderately | Stable market with aerospace/semiconductor demand support; no major volatility expected |
| Carbon Fiber T700 | 🟢 Hold & Watch | Capacity expansion driving prices down — defer large-volume procurement, await stabilization |
| PI Film | 🟡 Standard Purchase | Stable electronic-grade demand; domestic substitution improving cost-performance ratio |
| Silicon Carbide | 🟡 As-Needed | Firm cost support with limited volatility — avoid hoarding |
| Alumina | 🟡 Monitor Supply | Shanxi environmental inspections ongoing — maintain 2-week safety stock |
