Description

Poly(Vinylamine) Hydrochloride is a cationic, water-soluble polymer derived from the hydrolysis of poly(N-vinylformamide). This unique polyelectrolyte is valued for its high density of primary amine functional groups, which provide exceptional reactivity and binding capacity. It is a critical material for industries requiring advanced flocculation, surface modification, and chemical cross-linking. Key sectors utilizing this polymer include water treatment, paper manufacturing, personal care, and biomedical research.

Application

• Water & Wastewater Treatment: Acts as a highly effective cationic flocculant and coagulant aid for the removal of suspended solids, organic matter, and heavy metals.
• Paper & Pulp Industry: Used as a wet-strength additive, retention aid, and drainage promoter to improve paper quality and production efficiency.
• Personal Care & Cosmetics: Functions as a conditioning agent and film-former in hair care and skincare formulations due to its cationic nature and substantivity.
• Biomedical & Life Sciences: Employed in gene transfection, enzyme immobilization, and as a building block for hydrogels and drug delivery systems.
• Textile & Leather Processing: Serves as a dye-fixing agent, anti-static agent, and functional coating to enhance fabric properties.
• Adhesives & Sealants: Utilized as a cross-linking agent and modifier to improve adhesive strength and water resistance.

Quality Control

Our Poly(Vinylamine) Hydrochloride is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, molecular weight distribution, and performance. Certificates of Analysis (COA) detailing key parameters such as assay, chloride content, viscosity, and residual monomers are provided with every shipment. We adhere to relevant industry standards and can support requirements for GMP, ISO, or other specific regulatory frameworks upon request.

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 absorption of atmospheric moisture, which can affect product performance.
