Description

Sodium Acrylate-Acrylamide-N,N''-Methylenebis(Acrylamide) Polymer is a high-performance, cross-linked copolymer designed for demanding industrial applications. This material is engineered to provide exceptional water absorption and retention capabilities, forming stable hydrogels under various conditions. It is essential for manufacturers in sectors requiring advanced fluid management, superabsorbent properties, and rheology modification. The compound is identified by CAS number 33882-67-6.

Application

• Superabsorbent Polymers (SAPs): A key component in the production of high-capacity SAPs for hygiene products such as diapers, adult incontinence pads, and feminine care items.
• Agricultural Hydrogels: Used as a soil conditioner to improve water retention, reduce irrigation frequency, and enhance seed germination in arid climates.
• Industrial Waste Treatment: Employed as a flocculant or absorbent gel for solidifying liquid waste, managing sludge, and controlling environmental spills.
• Construction Materials: Incorporated into cementitious mixes and coatings as a water-retaining agent to control curing, reduce cracking, and improve workability.
• Drilling Fluids: Functions as a viscosifier and fluid loss control additive in water-based drilling muds for oil and gas exploration.
• Personal Care & Cosmetics: Serves as a thickener, stabilizer, and moisture-locking agent in creams, lotions, and gel-based formulations.
• Medical & Pharmaceutical: Utilized in wound dressings, drug delivery systems, and other hydrogel-based medical devices for controlled fluid interaction.
• Cable Water-Blocking: Applied in the powder form within telecommunications and power cables to prevent water penetration and propagation.

Quality Control

Our production of Sodium Acrylate-Acrylamide-N,N''-Methylenebis(Acrylamide) Polymer adheres to stringent quality management protocols. Each batch is tested against comprehensive specifications for critical parameters such as absorption capacity, residual monomers, particle size distribution, and moisture content. We provide Certificates of Analysis (COA) with every shipment to ensure traceability and compliance with your technical requirements. Our quality system is designed to support applications requiring consistency, from industrial grades to more specialized formulations.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Keep the original container sealed when not in use to prevent moisture uptake and caking. Store away from incompatible materials such as strong oxidizing agents.
