Description

Triphosphate is a versatile inorganic salt widely used as a key intermediate and functional additive in industrial processes. Its primary value lies in its ability to act as a sequestrant and dispersant, effectively controlling water hardness and preventing scale formation. This product is essential for manufacturers in sectors such as water treatment, detergent formulation, and ceramic production, where consistent quality and reliable performance are critical.

Application

• Water Treatment: Acts as a scale and corrosion inhibitor in cooling towers, boilers, and reverse osmosis systems.
• Detergent & Cleaning Formulations: Serves as a builder to sequester calcium and magnesium ions, enhancing surfactant efficiency and preventing dirt redeposition.
• Ceramic & Glass Industry: Used as a dispersing agent for clays and pigments to improve slurry stability and processing.
• Oilfield Chemicals: Functions as a component in drilling muds and completion fluids for scale control.
• Food Processing (Technical Grade): Employed in equipment cleaning and water treatment applications within food manufacturing facilities.
• Metal Surface Treatment: Assists in cleaning and phosphating processes for metal finishing.

Quality Control

Our Triphosphate is manufactured under a stringent quality management system to ensure batch-to-batch consistency and reliability. Quality is verified against established specifications for key parameters such as assay (P2O5 content), bulk density, and pH. Certificates of Analysis (COA) documenting these results are provided with every shipment. We can supply grades compliant with various industry standards, including food-grade (FCC) and technical specifications, upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent caking and degradation due to absorption of atmospheric moisture. Store away from incompatible materials.
