High-Purity Diammonium Phosphate (DAP) 21-53-0 from China Suppliers | Factory & Water Soluble Fertigation Solutions
Product Overview
Diammonium Phosphate (DAP) 21-53-0 Tech Grade is a high-purity, fully water-soluble phosphate material designed for industrial processing, fertilizer blending, and advanced fertigation systems. Unlike conventional granular Diammonium Phosphate used in bulk agriculture, this Tech Grade Diammonium Phosphate (DAP) is produced in crystalline form with strict control over solubility, impurity levels, and stability in solution.
This product is developed to meet the growing demand for water-soluble phosphate sources in modern agricultural and industrial applications, where rapid dissolution, compatibility, and consistency are critical. As a premium Diammonium Phosphate (DAP), it provides a reliable source of nitrogen and phosphorus for precision nutrient delivery systems.
Production Process and Quality Control
Tech Grade Diammonium Phosphate (DAP) is manufactured through a controlled neutralization process using purified phosphoric acid and ammonia. Compared with standard agricultural-grade Diammonium Phosphate, the Tech Grade DAP undergoes additional purification and crystallization steps to ensure consistent quality across all batches.
Lower Insoluble Content
Minimizes residue and system blockages during application.Higher Purity in Solution
Delivers clarity and consistency in liquid formulations.Reduced Heavy Metals
Meets stringent industrial and food-grade safety requirements.Stable Chemical Composition
Ensures batch-to-batch reliability for blending and dosing.The result is a Diammonium Phosphate (DAP) that performs consistently in high-demand applications, especially where filtration systems, injectors, or mixing tanks are sensitive to impurities.
