Description

Potassium Polyacrylate is a high-performance, water-absorbing polymer salt derived from polyacrylic acid. This compound is valued for its exceptional ability to absorb and retain large volumes of aqueous fluids, forming stable hydrogels. It is a critical material for industries requiring advanced moisture management, superabsorbent properties, and soil conditioning. Potassium Polyacrylate CAS NO 25608-12-2 serves as a versatile functional polymer in agriculture, personal care, and various industrial applications.

Application

• Agricultural Hydrogels: Used as a soil conditioner and water-retaining agent to improve water-holding capacity in arid regions and reduce irrigation frequency.
• Personal Care Products: A key ingredient in disposable hygiene products such as diapers, adult incontinence pads, and feminine hygiene items for its superior absorbency.
• Industrial Water Management: Employed in water-blocking tapes, cables, and construction materials for sealing and waterproofing applications.
• Horticulture & Gardening: Incorporated into potting mixes and growing media to maintain consistent moisture levels for plants.
• Medical & Wound Care: Utilized in advanced wound dressings and medical pads to manage exudate and maintain a moist healing environment.
• Desiccant & Humidity Control: Acts as a moisture absorber in packaging for electronics, pharmaceuticals, and sensitive goods.
• Waste Solidification: Applied to solidify liquid industrial waste for safer and easier disposal or transportation.
• Research & Development: Serves as a model polymer for studying hydrogel properties, drug delivery systems, and smart materials in academic and industrial labs.

Quality Control

Our Potassium Polyacrylate is manufactured under a strict quality management system. Each batch undergoes rigorous testing for critical parameters including absorbency capacity, purity, particle size distribution, and residual monomers to ensure consistent performance and reliability. Certificates of Analysis (COA) documenting full specifications 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). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent moisture absorption and caking.
