Wanhua Chemical began maintenance at its phenol and acetone unit on August 10, 2026, according to a plant status tracker. The phenol/acetone maintenance coincided with the start of the company's 45-day BPA unit turnaround.
Integrated maintenance across the phenol/acetone and BPA chain removes significant capacity from the market simultaneously. Wanhua is China's largest producer of BPA and a major buyer of phenol and acetone feedstock.
