Market Analysis

Updated:2026-09▲ Up this month
This Month's Trend

In September MEK rose with the solvent chain and crude costs, East China prices moving from about 8,350 to 9,200 RMB/t — a weekly gain of about 10% and roughly +30% YoY.

Key Drivers
  • Crude and C4-chain costs lifted MEK cost support
  • Downstream coatings, adhesives and synthetic leather improved on 'Golden September' demand
  • Export orders and shipping节奏 affect short-term supply节奏
Outlook

Short term firm oscillation; medium term, if crude stabilises and new supply is released, prices may range-bound. Lock volumes as needed.
