Description

Starch, Polymer With 2-Propenoic Acid, Graft, Sodium Salt is a high-performance, water-soluble graft copolymer derived from starch and acrylic acid. This engineered material is valued for its exceptional thickening, water absorption, and film-forming properties, making it a versatile functional additive. It is primarily utilized in industries such as personal care, textiles, and water treatment, where its unique combination of natural polymer backbone and synthetic graft chains delivers superior performance over conventional starches or polyacrylates alone.

Application

• Superabsorbent Polymers (SAPs): A key component in the manufacture of absorbent cores for hygiene products like diapers, adult incontinence pads, and feminine care items.
• Personal Care & Cosmetics: Functions as a thickener, stabilizer, and film-forming agent in creams, lotions, hair gels, and masks, providing a smooth texture and enhanced product stability.
• Textile Sizing & Finishing: Used as an eco-friendly sizing agent for yarns to reduce breakage during weaving and as a finishing agent to impart stiffness or handle to fabrics.
• Water Treatment: Acts as a flocculant aid and sludge dewatering agent due to its anionic character and ability to bridge particles.
• Adhesives & Binders: Serves as a biodegradable and renewable component in paper coatings, corrugated board adhesives, and other binding applications.
• Agriculture: Employed in soil conditioners and hydrogels for controlled-release fertilizers and to improve soil water retention.
• Oilfield Chemicals: Utilized as a fluid loss control additive and viscosifier in drilling muds and completion fluids.

Quality Control

Our production of Starch, Polymer With 2-Propenoic Acid, Graft, Sodium Salt adheres to stringent quality management protocols. Each batch undergoes rigorous testing to ensure consistent performance in key parameters such as absorbency, viscosity, and purity. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

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); ensure the container is kept tightly sealed to prevent caking or degradation due to atmospheric moisture.
