Description

Sodium Methacrylate CAS NO 5536-61-8 is the sodium salt of methacrylic acid, a versatile monomer essential for creating water-soluble polymers. This compound is a key building block for imparting anionic character and enhanced functionality to polymeric materials. It is primarily used by manufacturers in the water treatment, personal care, coatings, and textile industries to synthesize superabsorbent polymers, dispersants, and rheology modifiers.

Application

• Superabsorbent Polymers (SAPs): A critical monomer for manufacturing SAPs used in hygiene products like diapers and adult incontinence pads.
• Water Treatment Chemicals: Used in the synthesis of scale inhibitors and dispersants for industrial water systems and desalination plants.
• Coatings and Adhesives: Serves as a functional monomer to improve adhesion, water resistance, and rheological properties in acrylic paints, pressure-sensitive adhesives, and textile coatings.
• Personal Care Products: Employed in the production of hair fixatives, thickeners, and film-forming agents in cosmetics and toiletries.
• Textile Auxiliaries: Used to create fabric finishes, dyeing assistants, and soil-release agents.
• Construction Chemicals: A component in concrete admixtures and cement modifiers to improve workability and reduce water content.
• Enhanced Oil Recovery (EOR): Used in polymer flooding applications to increase oil production from reservoirs.

Quality Control

Our Sodium Methacrylate is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) are provided with every shipment, detailing key parameters such as assay, moisture content, and inhibitor levels to guarantee batch-to-batch consistency and reliability for your polymerization processes.

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) and must be kept under dry conditions to prevent caking and hydrolysis. Keep away from heat sources and incompatible materials such as strong oxidizing agents.
