Description

2-Propenoic Acid, Polymer With Diethenylbenzene, Sodium Salt is a synthetic, cross-linked polyacrylate copolymer in its sodium salt form. This specialized polymer is valued for its exceptional water-absorbing and thickening properties, making it a critical functional additive in various industrial processes. It is primarily sought by manufacturers in the water treatment, personal care, and construction industries for its ability to modify rheology and retain moisture.

Application

• Water Treatment: Used as a superabsorbent polymer or flocculant aid in sludge dewatering and as a thickening agent in drilling muds for oil & gas applications.
• Personal Care & Cosmetics: Serves as a key rheology modifier and thickener in creams, lotions, and gels, and as an absorbent in hygiene products.
• Construction & Building Materials: Employed as a water-retaining agent and workability aid in cementitious mixes, mortars, and tile adhesives.
• Agriculture & Horticulture: Functions as a soil conditioner to improve water retention and aeration in arid climates or for potted plants.
• Paints & Coatings: Acts as a thickener and stabilizer to prevent pigment settling and control application viscosity in water-based formulations.
• Textile Processing: Utilized as a thickener for printing pastes and dye formulations to achieve precise print definition and color yield.

Quality Control

Our production of 2-Propenoic Acid, Polymer With Diethenylbenzene, Sodium Salt adheres to stringent quality management protocols. Each batch undergoes rigorous testing for critical parameters such as absorption capacity, viscosity, particle size distribution, and residual monomer content. Certificates of Analysis (COA) documenting full specifications are available upon request to ensure compliance with your specific application requirements.

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 in its original, sealed packaging until use to prevent caking and performance degradation due to moisture absorption.
