Quick Answer: SHMP for water treatment refers to the use of sodium hexametaphosphate as a polyphosphate chemical for sequestration, moderate scale control, and dispersion in selected water systems. It is often evaluated for iron and manganese sequestration, deposit management, and threshold scale inhibition, but it is not a universal solution for every RO, cooling-water, or […]
STPP & SHMP in Seafood Processing: Technical Guide to Yield, Texture, and Compliance In seafood processing, food-grade phosphates such as sodium tripolyphosphate (STPP, E451(i)) and sodium hexametaphosphate (SHMP, E452(i)) are used to support water retention, texture control, metal-ion sequestration, and process consistency in products such as shrimp, fish fillets, squid, and surimi-type systems. On Goway, […]
Choosing the right deflocculant for ceramic slurry depends on more than viscosity reduction alone. STPP, SHMP, and sodium silicate differ in pH behavior, dosing sensitivity, raw-material compatibility, and slurry stability over time. This guide compares the three options from a process-selection perspective, helping ceramic manufacturers evaluate which deflocculant is more suitable for tile, sanitaryware, glaze, […]
STPP in ceramic manufacturing refers to the use of sodium tripolyphosphate as a deflocculant and dispersant in ceramic slurry, glaze, engobe, and slip systems. Its main job is to improve particle dispersion, reduce slurry viscosity, and lower water demand at a given solids level. In practical terms, that means a ceramic plant can often achieve […]

Sodium tripolyphosphate (STPP) is a condensed phosphate used in food processing and industrial systems for moisture retention, chelation, dispersion, and water-softening control. In procurement practice, STPP evaluation should focus on grade suitability, batch-level documentation, analytical consistency, and delivery condition rather than quoted price alone. For product context, see our industrial sodium tripolyphosphate overview. Technical Parameters […]
Technical reference: This dosage guide summarizes common STPP dosing ranges by application (food and industrial), with calculation examples and risk controls. Final limits depend on product category and local regulations. Food use (typical): 0.2–0.5% Seafood soak: 0.3–0.5% Ceramic slurry: 0.1–0.5% Powder detergents: 10–40% pH (1%): 9.5–10.0 Dosage table Calculation examples Risk controls Compliance note: Food […]

Technical reference: This page explains how STPP (Na5P3O10) specifications are defined, what each parameter means, and how to verify an STPP COA for food-grade vs industrial-grade applications. Topic: STPP specification Core anchors: Assay • P2O5 • pH (1%) Typical assay: ≥ 94% Typical P2O5: 57–59% Typical pH (1%): 9.5–10.0 How to read an STPP COA […]
Disodium phosphate (often abbreviated as DSP in formulation; also called disodium hydrogen phosphate) is a neutral-to-mildly alkaline phosphate salt with the formula Na2HPO4. It is widely used because it delivers three “system-control” functions at once: reliable pH buffering (typically in the alkaline range), metal ion sequestration (binding Ca2+/Mg2+), and protein/dispersion stabilization. These properties make DSP […]
