Description

Poly(Allylamine) is a synthetic, cationic polymer derived from the monomer allylamine, characterized by a high density of primary amine functional groups along its polymer chain. This unique structure makes it a highly versatile and effective agent for binding, modifying, and stabilizing various materials through electrostatic and covalent interactions. It is a critical raw material for industries requiring advanced functional polymers, particularly in water treatment, biomedical research, and specialty coatings.

Application

• Water Treatment: Acts as a highly effective flocculant and coagulant aid for the removal of suspended solids, organic matter, and phosphates in municipal and industrial wastewater.
• Biomedical & Life Sciences: Used for surface modification, cell encapsulation, and as a building block for gene/drug delivery systems due to its positive charge and biocompatibility.
• Paper Manufacturing: Functions as a dry-strength additive and retention aid to improve paper quality and production efficiency.
• Personal Care & Cosmetics: Employed as a conditioning agent and film-former in hair care and skincare formulations.
• Adhesives & Sealants: Serves as a cross-linking agent and modifier to enhance adhesive strength and durability.
• Textile Industry: Used as a dye-fixing agent and for fabric finishing to improve color fastness and feel.
• Electronics: Applied in the fabrication of multilayer printed circuit boards (PCBs) and as a component in photoresists.
• Chromatography & Diagnostics: Utilized to functionalize surfaces and beads for ion-exchange chromatography and diagnostic assay platforms.

Quality Control

Our Poly(Allylamine) is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistency, purity, and performance. Key parameters such as molecular weight distribution, amine content, and impurity profiles are controlled. A comprehensive Certificate of Analysis (COA) detailing the specific results is provided with each shipment to guarantee compliance with your technical 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 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.
