Technical Data Sheet (Industrial Grade SHMP 68%)
For industrial procurement, the most important control points are total phosphate (as P2O5), solubility/clarity, and impurity management. The following table is a typical specification reference;
Shipped batch parameters follow the COA and customer requirement.
| Item | Typical Spec | Why It Matters | Risk if Uncontrolled |
|---|---|---|---|
| Total Phosphate (as P2O5) | 68.0% Min | Key performance indicator for sequestration / dispersion. | Lower activity → more dosage, unstable results, higher cost. |
| Appearance | White powder / glassy flakes | Form affects handling, dissolution speed, feeding method. | Poor dissolution → uneven feed and inconsistent performance. |
| Solubility / Clarity | High solubility in water | Supports stable dosing and dispersion in process water. | Haze/insolubles → deposit risk and filtration burden. |
| Standard Reference | HG/T 2519-2017 (or customized) | Clear standard helps incoming QC and claim handling. | Spec ambiguity → disputes and higher complaint risk. |
Tip: If you have stricter limits on heavy metals / insolubles or require tighter impurity controls, please tell us your plant SOP and market requirements—we can match your spec sheet.
Why Industrial Buyers Choose SHMP 68%
Strong Sequestration
Binds Ca2+, Mg2+, Fe3+ and other ions to reduce scaling, staining, and process instability—especially in hard water.
Effective Dispersion
Improves dispersion of solids and fine particles, helping prevent agglomeration and deposit formation in industrial systems.
Process Stability
Supports stable performance across variable water quality conditions and improves consistency in production environments.
B2B Supply Reliability
Industrial packaging options, export documentation support (COA, MSDS), and stable production supply for bulk buyers.
Typical Dosage & Feeding Guidance (Starting Reference)
The correct dosage depends on hardness, alkalinity, temperature, flow, and system design. Below is a practical starting range used by many plants; always validate with your own monitoring data.
| Application | Typical Starting Range | Feeding Method | Notes for Engineers |
|---|---|---|---|
| Boilers / Industrial Softening Support | 10–50 ppm (as product) | Dissolve → metering pump / dosing tank | Adjust by hardness and scaling tendency; confirm with deposit inspection and trend logs. |
| Cooling Towers | 5–30 ppm (as product) | Continuous dosing preferred | Coordinate with inhibitors/biocides; validate with blowdown and heat-transfer performance. |
| Ceramics / Slurry Dispersion | 0.05–0.30% (in slurry) | Add during mixing / controlled addition | Optimize for viscosity and surface finish; avoid overuse that destabilizes rheology. |
| Detergent Builder / Dispersion | Formulation-based | Dry blending / granulation | Often paired with compatible builder/dispersant systems; confirm compatibility with surfactants and enzymes. |
| Textile & Dyeing | 0.05–0.20% (bath) | Pre-dissolve → add to bath | Monitor precipitation, hardness, and pH drift; validate with product quality metrics. |
Important: All ranges above are references only. Final dosage should be determined by on-site monitoring, performance results, and your compliance/ESG requirements.
Industrial Applications & Performance Benefits
1) Water Treatment
SHMP functions as a powerful sequestrant to reduce hardness-ion interference, improve water stability, and help control scaling and deposits in industrial systems. Explore more in our Water Treatment Solutions.
2) Ceramics Industry
As a highly effective dispersant, SHMP improves ceramic slurry fluidity and processing stability, helping reduce defects and improve surface finish. Learn more at Ceramic & Construction Solutions.
3) Textile & Dyeing
SHMP helps reduce metal-ion interference in dye baths, improving color consistency and reducing precipitation issues in hard water areas.
4) Paper Making
Used to improve dispersion of fillers and pigments, enhancing paper uniformity and brightness while helping reduce deposits in process water.

FAQ
What does “P2O5 68% Min” mean for industrial SHMP?
“Total phosphate as P2O5” is the main performance indicator often used by industrial buyers to evaluate activity level. A higher P2O5 value generally means stronger sequestration and dispersion capability under comparable conditions. The shipped-batch COA should be used as the final reference.
Can SHMP be used in boilers and cooling towers?
Yes. SHMP is widely used as a sequestrant and scale-control aid in industrial water systems. The correct dosage depends on hardness, temperature, cycles of concentration, and system design. Always validate by monitoring scaling tendency and system performance.
Do you provide COA and MSDS for industrial SHMP?
Yes. We provide COA per batch and MSDS for export. If your plant requires customized impurity limits or additional testing items, please share your target specification for confirmation.
What is the shelf life and how should SHMP be stored?
Store in a cool, dry, well-ventilated area with moisture protection. Keep packaging sealed to avoid caking and performance loss due to humidity exposure. Shelf life depends on storage conditions; please confirm with your receiving SOP and warehouse environment.
