Description

Cellulose Acetate is a versatile synthetic polymer derived from cellulose, offering an excellent balance of clarity, toughness, and processability. This material is crucial for manufacturers seeking a high-performance, bio-based polymer with excellent film-forming properties and solvent resistance. It is widely utilized across industries such as textiles, filtration, coatings, and consumer goods for its unique functional characteristics.

Application

• Textile Fibers: Production of high-quality acetate fibers for apparel linings, dresses, and home furnishings.
• Filtration Media: Key component in the manufacture of high-flow, low-protein binding membranes for laboratory and biopharmaceutical filtration.
• Film and Sheet Casting: Used to produce clear, glossy films for packaging, photographic film bases, and protective coatings.
• Lacquer and Coating Formulations: Serves as a primary film-forming agent in specialty lacquers, inks, and wood finishes.
• Plastic Products: Molded into frames for eyewear, tool handles, and other consumer items requiring dimensional stability.
• Controlled Release Systems: Employed in pharmaceutical applications for tablet coatings and encapsulation.

Quality Control

Our Cellulose Acetate is manufactured under a strict quality management system. Each batch is tested against critical parameters including acetyl content, viscosity, and moisture to ensure batch-to-batch consistency and performance. Certificates of Analysis (COA) documenting these results are provided and available 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). Keep away from heat sources and open flames. The material is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent moisture uptake.
