Description

2-Propenoic Acid, 2-Methyl-, Sodium Salt, Polymer With Diethenylbenzene is a cross-linked, water-absorbing polymer known as a superabsorbent polymer (SAP). This material is valued for its exceptional capacity to absorb and retain aqueous solutions under load, making it a critical functional component in various industries. It is primarily sought by manufacturers in the hygiene, agriculture, construction, and specialty chemical sectors for its reliable performance in moisture management applications.

Application

• Hygiene Products: Core absorbent material in disposable diapers, adult incontinence pads, and feminine hygiene products.
• Agriculture & Horticulture: Used as a soil conditioner and water-retaining agent to improve moisture availability for plants and reduce irrigation frequency.
• Construction Materials: Incorporated into cementitious mixtures and sealants to provide internal curing, reduce shrinkage cracking, and control water migration.
• Cable & Wire Manufacturing: Acts as a water-blocking agent in telecommunications and power cables to prevent longitudinal water penetration.
• Waste Solidification: Employed to gel and solidify liquid industrial waste for safer and more efficient disposal or transportation.
• Medical & Wound Care: Utilized in advanced wound dressings and medical pads to manage exudate and maintain a moist healing environment.
• Packaging: Integrated into absorbent pads for food packaging to control drip and moisture in trays containing fresh meat, poultry, or seafood.

Quality Control

Our production of 2-Propenoic Acid, 2-Methyl-, Sodium Salt, Polymer With Diethenylbenzene adheres to stringent quality management protocols. Each batch is tested against key performance indicators such as absorbency under load, particle size distribution, and residual monomer content to ensure consistency and reliability. 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 product is hygroscopic (moisture-sensitive) and must be kept in its original, sealed packaging until use to prevent caking and performance degradation due to atmospheric moisture.
