Description

Glycine, N-(carboxymethyl)-N-[(3-ethenylphenyl)methyl]-, disodium salt, polymer with N-(carboxymethyl)-N-[(4-ethenylphenyl) methyl]glycine disodium salt, 1-(chloromethyl)-3-ethenylbenzene, 1-(chloromethyl)-4-ethenylbenzene, 1-(dichloromethyl)-3-ethenylben is a specialized polymeric chelating agent, commonly known as a polycarboxylate-based scale inhibitor. This high-performance polymer is engineered to effectively control scale formation and inhibit corrosion in complex aqueous systems. It is a critical component for industrial water treatment, oilfield production, and detergent formulations where superior sequestration of metal ions like calcium and magnesium is required.

Application

• Industrial Water Treatment: Primary application as a highly effective scale inhibitor and dispersant in cooling towers, boilers, and reverse osmosis (RO) systems.
• Oilfield Chemicals: Used in drilling fluids, completion brines, and production chemicals to prevent mineral scale deposition in downhole and surface equipment.
• Detergent & Cleaning Formulations: Acts as a powerful builder and sequestrant to enhance cleaning efficiency by inactivating water hardness ions.
• Pulp & Paper Processing: Employed as a chelant in bleaching processes and to control scale in paper mill white water systems.
• Textile Processing: Utilized in dyeing and finishing baths to sequester metal ions that can interfere with processes and affect fabric quality.
• Personal Care Products: Incorporated into formulations such as shampoos and liquid soaps for its chelating and stabilizing properties.

Quality Control

Our production of this polycarboxylate polymer adheres to stringent quality management protocols. Each batch is characterized for critical parameters including active content, molecular weight distribution, and chelation value to ensure consistent performance. Comprehensive Certificates of Analysis (COA) documenting purity, viscosity, pH, and residual monomer content are provided to guarantee the product meets your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. This product is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (15-25°C/59-77°F). Keep the container tightly sealed when not in use to prevent moisture absorption and caking.
