Description

2-Propenamide, Polymer With Formaldehyde And n-Methylmethanamine CAS NO 67953-80-4 is a cationic polyacrylamide-based polymer, specifically a Mannich-modified polyacrylamide. This chemical is valued for its high charge density and effectiveness as a flocculant and retention aid in aqueous systems. It is primarily needed by industries involved in water treatment, paper manufacturing, and mineral processing where efficient solid-liquid separation is critical.

Application

• Water & Wastewater Treatment: As a primary flocculant for clarifying industrial process water, municipal wastewater, and sludge dewatering.
• Paper & Pulp Industry: As a retention and drainage aid to improve fiber and filler retention on the paper machine wire, enhancing production efficiency and paper quality.
• Mineral Processing: For the settling and filtration of mineral tailings, including coal washing and beneficiation of ores.
• Textile Industry: As a dye-fixing agent and for the treatment of textile effluents.
• Oilfield Applications: In drilling mud formulations and as a component in enhanced oil recovery (EOR) processes.
• Industrial Process Aid: For solid-liquid separation in various chemical manufacturing processes.

Quality Control

Our 2-Propenamide, Polymer With Formaldehyde And n-Methylmethanamine is manufactured under a strict quality management system. Each batch undergoes rigorous testing for key parameters such as charge density, molecular weight, viscosity, and residual monomer content to ensure consistent performance. Certificates of Analysis (COA) documenting these 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); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
