Description

Starch, Acetate, Oxidized CAS NO 68187-08-6 is a chemically modified starch derivative engineered for enhanced performance in demanding industrial applications. This compound offers superior film-forming, binding, and thickening properties compared to native starch, making it a critical functional additive. It is essential for manufacturers in the paper, textile, adhesive, and food packaging industries seeking to improve product quality and process efficiency.

Application

• Paper & Paperboard Coating: Acts as a surface sizing agent and coating binder to enhance printability, smoothness, and strength.
• Textile Sizing & Finishing: Provides efficient warp sizing for yarns and improves fabric hand feel and stiffness in finishing applications.
• Adhesive Formulations: Serves as a biodegradable and renewable binder in corrugating, laminating, and remoistenable adhesives.
• Food Packaging: Used in barrier coatings and biodegradable films for food contact materials, offering improved moisture resistance.
• Pharmaceutical Excipient: Functions as a tablet binder and disintegrant in controlled-release formulations.
• Construction Materials: Employed as an additive in gypsum boards and cement-based products to improve workability and adhesion.

Quality Control

Our Starch, Acetate, Oxidized is manufactured under a strict quality management system. Each batch is tested to ensure it meets precise specifications for degree of substitution, viscosity, and purity. Certificates of Analysis (COA) documenting key parameters such as acetyl content, carboxyl content, and heavy metals are available upon request. We can supply grades compliant with relevant food additive (FCC, E1451) and industrial standards.

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 after opening to prevent caking and degradation due to moisture absorption. Keep away from strong oxidizing agents.
