PTA rebounded at night. The load reduction of PTA plant and the postponement of the commissioning of new plant also change the mentality of market participants. Fuhai Chuang's 4.5 million ton PTA plant recently reduced its load to 70% or 80% and is expected to maintain it until the end of May. The accumulation pressure of fundamentals from May to June is not big. Among them, the production of 3.3 million tons of Yisheng new material was postponed to July August, and the production of 2.5 million tons of new PX plant of Zhejiang Petrochemical was postponed to July. However, the polyester end and demand side were weak. Yesterday, the production and sales of filament staple fiber were 40-50%, and the downstream just needed to purchase. The polyester factory still had the pressure to go to the warehouse, and the start-up of the plant dropped to 90%. PTA spot price continued to discount, and the basis rose. Polyester plants reduce their load, PTA price can hardly rise too much, hold short position at 4950-5000 area .
