96 Pure STPP Sodium Tripolyphosphate Powder Water Free SGS ISO

Technical Grade ≥ 96% Cas. 7758-29-4 STPP For Protect Pipe

• Molecular formula: Na5P3O10
• Molecular weight: 367.86
• Industrial grade CAS 7758-29-4
• Industrial grade products & COA meets GB/T 9983-2004 standard

• Chemical Formula: Na₅P₃O₁₀
• Molecular Weight: 367.86 g/mol
• Appearance: White crystalline or powdery solid
• Form: Typically exists as an anhydrous compound (Na₅P₃O₁₀) or a hexahydrate (Na₅P₃O₁₀*6H₂O)
• Water Solubility: Highly soluble in water, with solubility increasing with temperature
• Other Solvent: Insoluble in organic solvents (e.g., ethanol)
• Aqueous Solution pH: The pH of a 1% aqueous solution is approximately 9.5-10.5, making it alkaline
• Decomposition Temperature: Decomposes at high temperatures (around 622°C) into sodium pyrophosphate (Na₄P₂O₇) and sodium metaphosphate (NaPO₃)
• Hydrate Stability: The hexahydrate tends to effloresce in dry air, losing its water of crystallization
• Property: Strong hygroscopicity; easily absorbs moisture from the air and may form clumps
• Property: STPP has strong chelating ability, forming stable soluble complexes with metal ions such as calcium, magnesium, and iron in water
• Application: This property makes it highly valuable in water treatment, detergents, and food processing

Western Europe: the most stringent environmental regulations, the use of sodium tripolyphosphate is greatly limited, and the market share is gradually replaced by alternatives.

Eastern Europe: Environmental regulations are relatively relaxed, and the use of sodium tripolyphosphate is high, but with the gradual implementation of the EU environmental policy, it may be more restricted in the future.

Environmentally friendly products: With the increase of environmental awareness, the use of sodium tripolyphosphate will be further reduced, and more environmentally friendly alternatives will be promoted.

Sustainable development: The European chemical industry will pay more attention to sustainable development, and the production and use of sodium tripolyphosphate will pay more attention to environmental protection and resource conservation.

Challenge:

• Increasingly stringent environmental regulations have restricted the use of sodium tripolyphosphate
• Increased competition from alternatives could affect their market share

Chance:

• In specific areas such as water treatment and food processing, sodium tripolyphosphate still has a certain market demand
• Technological advances and process improvements provide new opportunities for environmentally friendly applications of sodium tripolyphosphate

The development prospects of sodium tripolyphosphate in Europe are strictly limited by environmental regulations, and its use has been significantly reduced in areas such as detergents, and its market share has been gradually replaced by environmentally friendly alternatives. However, in certain areas such as food processing and water treatment, sodium tripolyphosphate still has a certain market demand. In the future, with the enhancement of technological progress and environmental awareness, the application of sodium tripolyphosphate will pay more attention to environmental protection and sustainable development.
