Description

Sodium (4-Nonylphenyl) Phosphonate is an organophosphorus compound widely utilized as a high-performance scale and corrosion inhibitor. Its molecular structure provides excellent chelating and threshold inhibition properties, making it critical for protecting industrial water systems. This product is essential for chemical suppliers, water treatment formulators, and manufacturers in sectors requiring robust process water management.

Application

• Industrial Water Treatment: Primary application as a scale inhibitor for calcium carbonate, sulfate, and phosphate scales in cooling towers, boilers, and reverse osmosis systems.
• Corrosion Inhibition: Used in formulations to protect metal surfaces, particularly in recirculating cooling water and closed-loop heating systems.
• Detergent & Cleaning Formulations: Acts as a builder and sequestrant in industrial and institutional cleaning products to inactivate water hardness ions.
• Oilfield Chemicals: Employed in scale squeeze treatments and as a component in production chemicals to prevent mineral scale deposition in wells and pipelines.
• Pulp & Paper Processing: Serves as a dispersant and chelant to control scale in digesters, washers, and bleach plants.
• Textile Auxiliaries: Used in dyeing and finishing baths to sequester metal ions and prevent spotting or uneven dyeing.

Quality Control

Our Sodium (4-Nonylphenyl) Phosphonate is manufactured under a stringent quality management system. Each batch is tested to ensure consistent performance as a scale inhibitor. Key parameters including active content, pH, and solubility are verified. Certificates of Analysis (COA) documenting purity and specifications are available for every shipment to support your quality assurance protocols.

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); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which may affect product performance.
