Description

Polyphosphoric Acids, Potassium Salts are a versatile class of inorganic compounds, primarily valued for their role as effective sequestrants, dispersants, and buffering agents in industrial formulations. This product is crucial for processes requiring the control of water hardness ions and the stabilization of pH in aqueous systems. It finds significant utility across diverse sectors including water treatment, detergent manufacturing, ceramic production, and as a component in specialty cleaning and textile processing chemicals.

Application

• Water Treatment: Acts as a scale inhibitor and sequestrant for calcium and magnesium ions in boiler and cooling water systems.
• Detergent & Cleaner Formulations: Serves as a builder and dispersant to enhance cleaning efficiency and prevent soil redeposition.
• Ceramic & Clay Processing: Used as a deflocculant to control the viscosity and rheology of slips and slurries.
• Textile Processing: Functions as a dispersing agent in dyeing and printing processes and as a stabilizer in peroxide bleaching baths.
• Industrial & Institutional (I&I) Cleaners: A key ingredient in metal cleaning and dairy/brewery cleaning formulations for its sequestering power.
• Pulp & Paper Industry: Employed in peroxide bleaching stages to stabilize the bleaching agent and improve pulp brightness.
• Oilfield Applications: Can be used as a clay stabilizer and scale inhibitor in drilling and production fluids.
• Food Processing Equipment Cleaners: Incorporated into formulations for its ability to bind mineral ions that interfere with cleaning.

Quality Control

Our Polyphosphoric Acids, Potassium Salts are manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets defined specifications for parameters such as P2O5 content, potassium oxide (K2O) content, pH, and solubility. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 or degradation due to absorption of atmospheric moisture. Store away from strong acids.
