In polyester, PTA market supply has tightened notably recently, with multiple production lines cutting loads or shutting down, affecting an estimated 12.75 million tonnes of capacity, or about 13 to 14 percent of total industry capacity. Supply-side disruptions may widen PTA processing margins, while upstream feedstock bottlenecks could further strengthen polyester products' pricing power and profit recovery potential.
