Recently, the market of flake caustic soda has risen in Tianjin. While the mainstream ex-factory price of local 99%-concentrated flake caustic soda is 5050-5100 yuan/ton, up 150-200 yuan/ton, the price is 4900-4950 yuan/ton for flake alkali with a concentration of 96%. Meanwhile, some transactions ended up at a lower price. Local manufacturers mainly produce flake caustic soda by the large pot process. Now, these plants work at a stable operating load, producing a normal amount of goods and leaving the inventory at a reasonable level. At the same time, downstream sectors in textile, dyeing, chemicals and healthcare operate steadily, increasing the stocks before the National Day holiday. With the cost increase of liquid caustic soda, the market price of flake alkali rises.
