Sodium Hexametaphosphate (SHMP) 68%

Sodium hexametaphosphate (SHMP) is a kind of sodium phosphate polymer, which is usually white powder crystal or transparent glass flake in appearance. The SHMP chemical has strong hygroscopic property and will become sticky after hygroscopic. It is very easy to deliquescent in air and soluble in water with higher solubility and milder dissolution rate. Its aqueous solution is acid and easy to hydrolyze to phosphite. In addition, SHMP chemical has ability to form a soluble complex for some metal ions, so it can be used to soft water, as well as a wide range of uses in food processing and various industry fields.

Main Applications of Sodium Hexametaphosphate

• Food additives. As a food additive, sodium hexametaphosphate is mainly used to improve food quality, such as as a preservative, stabilizer, leavening agent, etc. It can improve the taste and texture of food and extend the shelf life of food.
• Industrial water treatment. SHMP is used as a water softener, dispersant, scale inhibitor, etc. in industrial water treatment. It can chelate hardness ions such as calcium and magnesium in water, reduce water hardness, and prevent the formation of scale.
• Textile and papermaking. In the textile industry, sodium hexametaphosphate is used as a dyeing auxiliary, bleaching stabilizer, etc., which can improve the coloring rate and color fastness of dyes. In the papermaking industry, it can be used as a sizing agent, reinforcing agent, etc. to improve the water resistance and strength of paper.
• Petroleum and metallurgy. In the process of oil extraction and smelting, sodium hexametaphosphate can be used as a flotation agent, corrosion inhibitor, etc. to help improve the mining efficiency of mineral resources and the quality of metals.
• Other fields. Sodium hexametaphosphate is also widely used in ceramics, glass, rubber, plastics and other industries as an additive, modifier, etc.

Performance Characteristics​

As an important inorganic compound, SHMP chemical has a series of unique characteristics, which make them widely used in many fields. The following is an introduction to the main characteristics of sodium hexametaphosphate SHMP:

• Excellent complexing ability. SHMP chemical can form stable complexes with a variety of metal ions, especially with calcium, magnesium, iron and other metal ions. This characteristic makes SHMP have important application value in the separation, purification and chelation of metal ions.
• Good water solubility and dispersibility. This chemical is easily soluble in water and can quickly form a uniform solution. At the same time, it can also effectively disperse particulate matter and prevent it from agglomerating, thereby improving the stability and fluidity of the system.
• Buffering performance. It can adjust the pH value of the solution within a certain range and play a buffering role. This makes SHMP play an important role in the process that needs to maintain a specific pH environment.
• High temperature resistance. SHMP can remain stable at high temperatures and is not easy to decompose or fail. This characteristic makes SHMP advantageous in the application of high temperature environments, such as in the textile, papermaking and other industries as a high temperature additive.
• Versatility. The product has multiple functions and can play different roles in different fields. For example, in the food industry, SHMP can be used as a quality improver to improve the taste and texture of food; in the textile industry, it can be used as a dyeing auxiliary to improve the dyeing rate and color fastness of dyes; in the papermaking industry, SHMP can be used as a sizing agent to improve the water resistance and strength of paper, etc.
• Compatibility. SHMP generally has good compatibility with other chemicals and can be mixed with a variety of substances without adverse reactions or reduction of its performance.
• Non-toxicity and safety. It is considered safe in the food industry and will not have toxic effects on the human body. At the same time, it also has good environmental performance and will not pollute the environment.
• Easy to store and transport. SHMP sodium hexametaphosphate has good stability at room temperature and is not easily affected by moisture, agglomeration or deterioration. It is usually stored and transported in solid form, which is convenient for storage and use.
