Since this year, yellow phosphorus prices have shown three waves of significant price increases. Since the second quarter, the price supply of yellow phosphorus has been significantly higher than that in previous years, and the overall inventory of yellow phosphorus has been continuously consumed. In the state of low inventory, the downstream demand of yellow phosphorus is rigidly supported, which effectively improves the price of yellow phosphorus. Insufficient supply continues to consume inventory, and the price of sodium hexametaphosphate rises.

As the key product of the thermal process, yellow phosphorus is mainly used in the downstream of phosphorus containing pesticides, phosphorus containing chlorides and thermal phosphoric acid. Among them, phosphate with high-quality thermal phosphoric acid as raw material is irreplaceable, which has become the rigid demand of yellow phosphorus downstream.

Sodium hexametaphosphate is a water softener, retarder, refractory additive and so on commonly used in industry. It is a high-quality improver in food production. It needs thermal phosphoric acid as raw material to meet relevant production indicators.

In terms of food grade sodium hexametaphosphate, food grade sodium hexametaphosphate is some substances that are not used as the main raw material of food and for the purpose of eating. In order to have a certain effect on the properties of food or achieve the desired purpose, food grade sodium hexametaphosphate is consciously added to food in a small amount during food processing, packaging, transportation and preservation. Sodium hexametaphosphate produced by thermal phosphoric acid has low heavy metal content, clear aqueous solution and controllable impurities, which can better meet the subsequent production and use.

Sodium hexametaphosphate is widely used, so the price of sodium hexametaphosphate has reached a new high with the rise of yellow phosphorus. Chongqing Chuandong Chemical Group complied with the changes of the situation and timely adjusted the production of sodium hexametaphosphate to cope with the price rise.
