Crude oil futures continued to rise

Crude oil futures continued to rise, and the profit of polyester industry chain products continued to be compressed. In addition to PET bottle chips and DTY, all the other products are in a loss. In particular, PTA-PX margin has dropped to negative values for two consecutive days. If acetic acid cost is considered, PTA processing cost has dropped to -200yuan/mt, a new low in history. Under the influence of such low processing cost, will more PTA producers shut the units for maintenance in the later period?
