【Lead】: Amid factors such as the traditional off-season for PI film demand and the release of new production capacity in the pyromellitic anhydride market, domestic pyromellitic anhydride producers have been cutting prices to move volumes.

Under the accumulation of these multiple bearish factors, the durene market price has halted its stabilization and turned downward, with a sluggish buying and selling atmosphere.
