Description

Polyphosphonate CAS NO 38720-58-0 is a specialized organophosphorus compound known for its excellent chelating and scale inhibition properties. This chemical is critical for industries requiring precise control over water chemistry and metal ion sequestration to prevent equipment fouling and maintain process efficiency. It is primarily utilized by water treatment, industrial cleaning, and oilfield chemical formulation sectors.

Application

• Industrial Water Treatment: Acts as a highly effective scale and corrosion inhibitor in cooling towers, boilers, and reverse osmosis systems.
• Oilfield Chemicals: Used in drilling fluids and production chemicals to control scale formation in pipes and equipment under high-temperature, high-salinity conditions.
• Detergent & Cleaning Formulations: Serves as a powerful builder and chelating agent to enhance cleaning efficiency by sequestering hardness ions like calcium and magnesium.
• Pulp & Paper Processing: Employed to control scale and manage metal ion interference during bleaching and pulping operations.
• Textile Processing: Used in dyeing and finishing baths to prevent metal-ion catalyzed degradation of dyes and fabrics.
• Industrial Cleaning: A key component in acid cleaning formulations for industrial equipment to inhibit metal corrosion.

Quality Control

Our Polyphosphonate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance and meets relevant industry specifications for scale inhibition and chelation. Certificates of Analysis (COA) documenting key parameters such as active content, pH, density, and iron content 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, and well-ventilated area at room temperature (15-25°C/59-77°F). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance.
