检修装置重启，供应压力回升

Report Industry Investment Rating - Unspecified Core Viewpoints - Propylene supply pressure is significantly increasing, with short - term fundamentals showing no obvious improvement. New capacity is being released, and downstream demand is weak. However, PP powder production profit has recovered [3]. - For polyolefins, the third round of Sino - US economic and trade talks may bring positive news. Supply pressure is increasing due to the restart of maintenance devices and new device production. Cost - side support is weak, and downstream demand is mainly for rigid replenishment [3].
