PTA fluctuated in a narrow range last week. The PTA unit load increased to 82.5%. Fuhaichuang's 4.5 million ton PTA load will be gradually increased. Hengli Petrochemical's 2.5 million ton PTA unit is scheduled to be overhauled from June 1 and is expected to be overhauled for half a month. Polyester end, weak demand performance, polyester repair last week focused on restart, start increased by 2 percentage points to 92.5%. But the filament inventory is still accumulating. At the weekend, the filament factory will reduce the price by 100-300 yuan / ton for promotion, and the weaving factory will purchase the inventory for 1-2 weeks. The sustainability of polyester end load increase is questionable, PTA uplink space is not effectively opened.
