For industrial and food-grade applications, understanding the precise specifications of Sodium Tripolyphosphate (STPP) is crucial for ensuring optimal performance and regulatory compliance. As a bulk purchaser, your ability to source consistently high-quality STPP hinges on knowing what to look for. As a leading STPP manufacturer in China, we provide a comprehensive range of STPP products with detailed specifications to meet diverse industrial needs.

The most critical specification for STPP is its purity, typically indicated by the percentage of Na5P3O10. For most industrial applications, a purity of 94% minimum is standard, while food-grade STPP often requires slightly higher purity (e.g., ≥94.00% with stricter limits on impurities like iron, heavy metals, and arsenic). Another key parameter is the percentage of water-insoluble matter, which should be kept to a minimum (≤0.15% or lower) for optimal performance. The pH of a 1% solution, generally falling between 9.2-10.0, is also important for applications sensitive to alkalinity.

Particle size and form (powder vs. granular) are also significant considerations. Fine powders offer greater surface area and faster dissolution, often preferred for detergents requiring rapid mixing. Granular forms might offer better handling and reduced dust. When you buy STPP in bulk, clarify these physical characteristics with your supplier to ensure they align with your manufacturing processes. As a dedicated STPP supplier, we offer various grades to suit different requirements.

Furthermore, understanding the packaging and storage requirements is vital for maintaining product integrity. STPP should be stored in a dry environment, typically in plastic-woven sacks with polythene inner bags, to prevent moisture absorption. For bulk purchasers, discussing logistics and ensuring secure packaging is part of the procurement process. We are committed to transparency and providing clear product information to our clients. When inquiring about STPP price, consider the value derived from adherence to stringent specifications and reliable supply.

Making an informed decision when purchasing STPP in bulk requires a thorough understanding of these specifications. We encourage all bulk buyers to reach out to us for detailed product data sheets and to discuss their specific application needs. Partnering with a quality-conscious STPP manufacturer ensures you receive products that deliver consistent performance and value.
