Description

Cationic Amylopectin is a chemically modified starch derivative where cationic groups, typically quaternary ammonium salts, are introduced onto the amylopectin polymer backbone. This modification imparts a positive charge, making it a highly effective flocculant and retention aid in aqueous systems. It is essential for industries requiring efficient solid-liquid separation and charge neutralization. Key sectors that utilize this specialty chemical include paper manufacturing, water treatment, and personal care product formulation.

Application

• Paper & Pulp Industry: As a wet-end additive for improved retention of fines and fillers, enhanced drainage, and better sheet formation.
• Water & Wastewater Treatment: As a cationic flocculant for clarifying process water, treating industrial effluent, and sludge dewatering.
• Personal Care & Cosmetics: As a conditioning agent and thickener in shampoos, creams, and lotions, where it provides a smooth feel and aids in film formation.
• Textile Industry: As a sizing agent and finishing chemical to improve fabric handle, strength, and dye uptake.
• Oilfield Applications: As a component in drilling muds and completion fluids for viscosity control and shale inhibition.
• Adhesives & Construction: As a rheology modifier and binder in gypsum boards, tile adhesives, and other building materials.

Quality Control

Our Cationic Amylopectin is manufactured under a strict quality management system. Each batch is tested to ensure consistent performance in key parameters such as degree of substitution, viscosity, and charge density. Certificates of Analysis (COA) documenting purity, physical properties, and application performance 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); the container must be kept tightly sealed to prevent caking or degradation due to moisture absorption.
