In terms of PTA supply, 700,000 tons of Yadong Petrochemical and 1.5 million tons of Honggang Petrochemical equipment were overhauled, and the operating rate dropped overall. Overhaul of 2.2 million tons of Hengli Petrochemical plant was postponed. On the cost side, the price of PX is weak. In the early stage, it is expected that the new PTA device will be put into production to stock the PX, but the actual start-up is delayed, which makes the supply of PX appear loose and the spread of PX naphtha decreases. PTA spot processing fee is about 600 yuan/ton. In terms of polyester, the Xiaoshan Plant continued to reduce its load, and the overall polyester load dropped to 90%. The start of the Shengze loom was regulated by environmental protection, and the start of the operation was two and one was stopped. Last week, the purchase of the loom was roughly stocked in about 1-2 weeks, and the stock was stocked until around the Dragon Boat Festival. Sluggish terminal orders have limited the upside of raw material prices.
