Description

Calgon CAS NO 59299-44-4 is a high-purity, water-soluble polymer widely recognized for its exceptional sequestering and dispersing properties. This product is critical for controlling scale formation and preventing corrosion in industrial water systems, ensuring operational efficiency and equipment longevity. It is an essential component for water treatment specialists, formulators of cleaning and detergent products, and professionals in the pulp & paper and textile processing industries.

Application

• Industrial Water Treatment: Primary application as a highly effective scale and corrosion inhibitor in cooling towers, boilers, and reverse osmosis systems.
• Detergent & Cleaning Formulations: Acts as a powerful builder and sequestrant to enhance cleaning efficacy by inactivating water hardness ions (calcium, magnesium).
• Pulp & Paper Processing: Used to control metal ions and prevent deposits during bleaching and papermaking processes, improving product quality and mill efficiency.
• Textile Processing: Employed as a dispersant and sequestrant in dyeing and scouring baths to ensure even color application and prevent staining from metal impurities.
• Oilfield Applications: Functions as a scale inhibitor in water flooding and production operations to maintain well productivity and flow assurance.
• Personal Care Products: Incorporated into formulations such as shampoos and liquid soaps as a chelating agent to stabilize the product and improve performance.
